Because of climate change, last summer was the hottest in the Northern Hemisphere in 2,000 years—and this summer is expected to be even hotter. The record may continue to be broken: Extreme heat is expected to become even more frequent.
The scorching heat has led to an increase in heat-related deaths in the United States, according to the Department of Health and Human Services, with approximately 2,300 deaths in the summer of 2023. Extreme heat, defined as a period of two to three days with high heat and humidity with temperatures above 90 degrees Fahrenheit, can have serious health consequences, including symptoms like headache, dizziness, loss of consciousness, nausea, and confusion.
As we face more extreme heat, you may be wondering how you can protect yourself and your loved ones. Read on to learn about heat-related illness, who’s most at risk, and more.
What happens when our bodies are exposed to extreme heat?
As our body temperature rises, our bodies attempt to cool down by opening up more blood vessels near the skin to begin sweating. The evaporation of our sweat regulates our body temperature, but it also leads to losing fluids and minerals.
When it’s too humid, sweating alone doesn’t do the trick. The heart must work harder to bring blood around the body. It starts beating faster, which can cause light-headedness, nausea, and headache.
This process can affect our health in different ways, including increasing our risk of hospitalization for heart disease, worsening asthma, and injuring kidneys due to dehydration. It can also result in heat-related illness. Below are some effects of heat on our bodies:
- Heat cramps: Occur when a person loses salt through sweating, which causes painful cramps. Symptoms begin as painful spasms after heavy sweating, usually in the legs or the stomach. Heat cramps can lead to heat exhaustion or heat stroke.
- Heat exhaustion: This occurs when the body loses an excessive amount of water and salt, usually during intense physical activity. Symptoms include irritability, heavy sweating, and weakness, including muscle cramps. Heat exhaustion can lead to heat stroke.
- Heat stroke: This is the most severe heat-related illness. It happens when the body can’t cool down and reaches a temperature of 106 Fahrenheit or higher within 10 to 15 minutes. If the person doesn’t receive emergency treatment, it can cause permanent disability or death. Symptoms include confusion, loss of consciousness, and seizures.
What should I do if someone experiences a heat-related illness?
If you or someone you’re with begins to show signs of heat illness, the Centers for Disease Control and Prevention recommends the following:
- Heat cramps: Stop all physical activity, drink water or a sports drink, move to a cool place, and wait for cramps to go away before resuming activity. If the cramps last more than an hour, you’re on a low-sodium diet, or you have heart problems, get medical help.
- Heat exhaustion: Move the person to a cool place, loosen their clothes, use a cool bath or cloths to try to lower their body temperature, and give them a sip of water. If the person throws up, or if their symptoms last longer than an hour or worsen, get medical help.
- Heat stroke: Call 911 immediately. Then, move the person to a cooler place, use cool cloths or a cool bath to help lower their temperature, and don’t give them anything to drink.
Read more about heat-related illness and what to do in each case.
Who’s more vulnerable to extreme heat?
While everyone can be affected by extreme heat, some people are more at risk, including people of color.
A 2023 KFF report outlined that because of historical residential segregation in the U.S. (known as “redlining”), people of color are more likely to live in areas that experience higher temperatures from rooftops, asphalt, and sidewalks that retain the sun’s heat (known as the “urban heat island effect”). Additionally, communities of color are more likely to live in areas with fewer trees, which act as a canopy and provide shade, making the heat worse and more direct.
Children under 5, adults 65 or over, and pregnant people are also more vulnerable to extreme heat. If you have a chronic health condition like diabetes, heart problems, or a mental health condition, you’re also at higher risk. (Some psychiatric medications, like antidepressants, can also make people more susceptible to heat).
Lastly, anyone exposed to the sun and extreme heat for long periods is also at higher risk. This includes athletes, people who work outdoors, and unhoused people.
What can I do to prevent heat-related illness during a heat wave?
During a heat wave, follow these tips to stay cool and protect yourself from heat-related illness:
- Never leave your pets or children inside a car.
- Wear loose, light-colored clothing (dark colors absorb more heat).
- Find shade if you’re outside.
- If you don’t have air conditioning in your home, go to a place where you can cool down, such as a local library, community center, local pool or splash pad, or mall. Check to see if your city has designated cooling centers. (Cities like New York have a list of places.)
- Wear a hat.
- Drink (non-alcoholic) fluids often to stay hydrated—and if you have pets, give them water frequently as well.
- Check on your family members or older neighbors who may be more sensitive to extreme heat.
- Avoid using your stove or oven too often or during the hottest parts of the day.
- Cover your windows with shades to keep the heat out.
What are some resources to prevent heat-related illness?
If you need financial assistance to cool down your home, such as to purchase an air conditioner, apply to the federal government’s Low Income Home Energy Assistance Program.
Before you head outside during a heat wave, use the CDC’s HeatRisk tool: Enter your zip code to find the current heat risk in your area and get tips on what to do to stay safe with each risk level.
During a heat wave, also look for a cooling center in your state using the National Center for Healthy Housing’s list.
Check out the National Weather Service’s for more tips and resources.

The first pig kidney has been transplanted into a living person. But we’re still a long way from solving organ shortages
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
In a world first, we heard last week that US surgeons had transplanted a kidney from a gene-edited pig into a living human. News reports said the procedure was a breakthrough in xenotransplantation – when an organ, cells or tissues are transplanted from one species to another. https://www.youtube.com/embed/cisOFfBPZk0?wmode=transparent&start=0 The world’s first transplant of a gene-edited pig kidney into a live human was announced last week.
Champions of xenotransplantation regard it as the solution to organ shortages across the world. In December 2023, 1,445 people in Australia were on the waiting list for donor kidneys. In the United States, more than 89,000 are waiting for kidneys.
One biotech CEO says gene-edited pigs promise “an unlimited supply of transplantable organs”.
Not, everyone, though, is convinced transplanting animal organs into humans is really the answer to organ shortages, or even if it’s right to use organs from other animals this way.
There are two critical barriers to the procedure’s success: organ rejection and the transmission of animal viruses to recipients.
But in the past decade, a new platform and technique known as CRISPR/Cas9 – often shortened to CRISPR – has promised to mitigate these issues.
What is CRISPR?
CRISPR gene editing takes advantage of a system already found in nature. CRISPR’s “genetic scissors” evolved in bacteria and other microbes to help them fend off viruses. Their cellular machinery allows them to integrate and ultimately destroy viral DNA by cutting it.
In 2012, two teams of scientists discovered how to harness this bacterial immune system. This is made up of repeating arrays of DNA and associated proteins, known as “Cas” (CRISPR-associated) proteins.
When they used a particular Cas protein (Cas9) with a “guide RNA” made up of a singular molecule, they found they could program the CRISPR/Cas9 complex to break and repair DNA at precise locations as they desired. The system could even “knock in” new genes at the repair site.
In 2020, the two scientists leading these teams were awarded a Nobel prize for their work.
In the case of the latest xenotransplantation, CRISPR technology was used to edit 69 genes in the donor pig to inactivate viral genes, “humanise” the pig with human genes, and knock out harmful pig genes. https://www.youtube.com/embed/UKbrwPL3wXE?wmode=transparent&start=0 How does CRISPR work?
A busy time for gene-edited xenotransplantation
While CRISPR editing has brought new hope to the possibility of xenotransplantation, even recent trials show great caution is still warranted.
In 2022 and 2023, two patients with terminal heart diseases, who were ineligible for traditional heart transplants, were granted regulatory permission to receive a gene-edited pig heart. These pig hearts had ten genome edits to make them more suitable for transplanting into humans. However, both patients died within several weeks of the procedures.
Earlier this month, we heard a team of surgeons in China transplanted a gene-edited pig liver into a clinically dead man (with family consent). The liver functioned well up until the ten-day limit of the trial.
How is this latest example different?
The gene-edited pig kidney was transplanted into a relatively young, living, legally competent and consenting adult.
The total number of gene edits edits made to the donor pig is very high. The researchers report making 69 edits to inactivate viral genes, “humanise” the pig with human genes, and to knockout harmful pig genes.
Clearly, the race to transform these organs into viable products for transplantation is ramping up.
From biotech dream to clinical reality
Only a few months ago, CRISPR gene editing made its debut in mainstream medicine.
In November, drug regulators in the United Kingdom and US approved the world’s first CRISPR-based genome-editing therapy for human use – a treatment for life-threatening forms of sickle-cell disease.
The treatment, known as Casgevy, uses CRISPR/Cas-9 to edit the patient’s own blood (bone-marrow) stem cells. By disrupting the unhealthy gene that gives red blood cells their “sickle” shape, the aim is to produce red blood cells with a healthy spherical shape.
Although the treatment uses the patient’s own cells, the same underlying principle applies to recent clinical xenotransplants: unsuitable cellular materials may be edited to make them therapeutically beneficial in the patient.
CRISPR technology is aiming to restore diseased red blood cells to their healthy round shape. Sebastian Kaulitzki/Shutterstock We’ll be talking more about gene-editing
Medicine and gene technology regulators are increasingly asked to approve new experimental trials using gene editing and CRISPR.
However, neither xenotransplantation nor the therapeutic applications of this technology lead to changes to the genome that can be inherited.
For this to occur, CRISPR edits would need to be applied to the cells at the earliest stages of their life, such as to early-stage embryonic cells in vitro (in the lab).
In Australia, intentionally creating heritable alterations to the human genome is a criminal offence carrying 15 years’ imprisonment.
No jurisdiction in the world has laws that expressly permits heritable human genome editing. However, some countries lack specific regulations about the procedure.
Is this the future?
Even without creating inheritable gene changes, however, xenotransplantation using CRISPR is in its infancy.
For all the promise of the headlines, there is not yet one example of a stable xenotransplantation in a living human lasting beyond seven months.
While authorisation for this recent US transplant has been granted under the so-called “compassionate use” exemption, conventional clinical trials of pig-human xenotransplantation have yet to commence.
But the prospect of such trials would likely require significant improvements in current outcomes to gain regulatory approval in the US or elsewhere.
By the same token, regulatory approval of any “off-the-shelf” xenotransplantation organs, including gene-edited kidneys, would seem some way off.

The Anti-Stress Herb That Also Fights Cancer
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
What does Rhodiola rosea actually do, anyway?
Rhodiola rosea (henceforth, “rhodiola”) is a flowering herb whose roots have adaptogenic properties.
In the cold, mountainous regions of Europe and Asia where it grows, it has been used in herbal medicine for centuries to alleviate anxiety, fatigue, and depression.
What does the science say?
Well, let’s just say the science is more advanced than the traditional use:
❝In addition to its multiplex stress-protective activity, Rhodiola rosea extracts have recently demonstrated its anti-aging, anti-inflammation, immunostimulating, DNA repair and anti-cancer effects in different model systems❞
Nor is how it works a mystery, as the same paper explains:
❝Molecular mechanisms of Rhodiola rosea extracts’s action have been studied mainly along with one of its bioactive compounds, salidroside. Both Rhodiola rosea extracts and salidroside have contrasting molecular mechanisms on cancer and normal physiological functions.
For cancer, Rhodiola rosea extracts and salidroside inhibit the mTOR pathway and reduce angiogenesis through down-regulation of the expression of HIF-1α/HIF-2α.
For normal physiological functions, Rhodiola rosea extracts and salidroside activate the mTOR pathway, stimulate paracrine function and promote neovascularization by inhibiting PHD3 and stabilizing HIF-1α proteins in skeletal muscles❞
~ Ibid.
And, as for the question of “do the supplements work?”,
❝In contrast to many natural compounds, salidroside is water-soluble and highly bioavailable via oral administration❞
~ Ibid.
And as to how good it is:
❝Rhodiola rosea extracts and salidroside can impose cellular and systemic benefits similar to the effect of positive lifestyle interventions to normal physiological functions and for anti-cancer❞
~ Ibid.
Source: Rhodiola rosea: anti-stress, anti-aging, and immunostimulating properties for cancer chemoprevention
But that’s not all…
We can’t claim this as a research review if we only cite one paper (even if that paper has 144 citations of its own), and besides, it didn’t cover all the benefits yet!
Let’s first look at the science for the “traditional use” trio of benefits:
When you read those, what are your first thoughts?
Please don’t just take our word for things! Reading even just the abstracts (summaries) at the top of papers is a very good habit to get into, if you don’t have time (or easy access) to read the full text.
Reading the abstracts is also a very good way to know whether to take the time to read the whole paper, or whether it’s better to skip onto a different one.
- Perhaps you noticed that the paper we cited for anxiety was quite a small study.
- The fact is, while we found mountains of evidence for rhodiola’s anxiolytic (antianxiety) effects, they were all small and/or animal studies. So we picked a human study and went with it as illustrative.
- Perhaps you noticed that the paper we cited for fatigue pertained mostly to stress-related fatigue.
- This, we think, is a feature not a bug. After all, most of us experience fatigue because of the general everything of life, not because we just ran a literal marathon.
- Perhaps you noticed that the paper we cited for depression said it didn’t work as well as sertraline (a very common pharmaceutical SSRI antidepressant).
- But, it worked almost as well and it had far fewer adverse effects reported. Bear in mind, the side effects of antidepressants are the reason many people avoid them, or desist in taking them. So rhodiola working almost as well as sertraline for far fewer adverse effects, is quite a big deal!
Bonus features
Rhodiola also putatively offers protection against Alzheimer’s disease, Parkinson’s disease, and cerebrovascular disease in general:
Rosenroot (Rhodiola): Potential Applications in Aging-related Diseases
It may also be useful in the management of diabetes (types 1 and 2), but studies so far have only been animal studies, and/or in vitro studies. Here are two examples:
- Antihyperglycemic action of rhodiola-aqeous extract in type 1 diabetic rats
- Evaluation of Rhodiola crenulata and Rhodiola rosea for management of type 2 diabetes and hypertension
How much to take?
Dosages have varied a lot in studies. However, 120mg/day seems to cover most bases. It also depends on which of rhodiola’s 140 active compounds a particular benefit depends on, though salidroside and rosavin are the top performers.
Where to get it?
As ever, we don’t sell it (or anything else) but here’s an example product on Amazon.

Rosehip’s Benefits, Inside & Out
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
It’s In The Hips
Rosehip (often also written: “rose hip”, “rosehips”, or “rose hips”, but we’ll use the singular compound here to cover its use as a supplement) is often found as an extra ingredient in various supplements, and also various herbal teas. But what is it and what does it actually do?
What it is: it’s the fruiting body that appears on rose plants underneath where the petals appear. They are seasonal.
As for what it does, read on…
Anti-inflammatory
Rosehip is widely sought for (and has been well-studied for) its anti-inflammatory powers.
Because osteoarthritis is one of the most common inflammatory chronic diseases around, a lot of the studies are about OA, but the mechanism of action is well-established as being antioxidant and anti-inflammatory in general:
❝Potent antioxidant radical scavenging effects are well documented for numerous rose hip constituents besides Vitamin C.
Furthermore, anti-inflammatory activities include the reduction of pro-inflammatory cytokines and chemokines, reduction of NF-kB signaling, inhibition of pro-inflammatory enzymes, including COX1/2, 5-LOX and iNOS, reduction of C-reactive protein levels, reduction of chemotaxis and chemoluminescence of PMNs, and an inhibition of pro-inflammatory metalloproteases.❞
Note that while rosehip significantly reduces inflammation, it doesn’t affect the range of movement in OA—further making clear its mechanism of action:
Read: Rosa canina fruit (rosehip) for osteoarthritis: a cochrane review
Anti-aging
This is partly about its antioxidant effect, but when it comes to skin, also partly its high vitamin C content. In this 8-week study, for example, taking 3mg/day resulted in significant reductions of many measures of skin aging:
Heart healthy
The dose required to achieve this benefit is much higher, but nonetheless its effectiveness is clear, for example:
❝Daily consumption of 40 g of rose hip powder for 6 weeks can significantly reduce cardiovascular risk in obese people through lowering of systolic blood pressure and plasma cholesterol levels. ❞
~ Dr. Mona Landin-Olsson et al.

How to Eat to Change How You Drink – by Dr. Brooke Scheller
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
Whether you want to stop drinking or just cut down, this book can help. But what makes it different from the other reduce/stop drinking books we’ve reviewed?
Mostly, it’s about nutrition. This book focuses on the way that alcohol changes our relationship to food, our gut, our blood sugars, and more. The author also explains how reducing/stopping drinking, without bearing these things in mind, can be unnecessarily extra hard.
The remedy? To bear them in mind, of course, but that requires knowing them. So what she does is explain the physiology of what’s going on in terms of each of the above things (and more), and how to adjust your diet to make up for what alcohol has been doing to you, so that you can reduce/quit without feeling constantly terrible.
The style is very pop-science, light in tone, readable. She makes reference to a lot of hard science, but doesn’t discuss it in more depth than is necessary to convey the useful information. So, this is a practical book, aimed at all people who want to reduce/quit drinking.
Bottom line: if you feel like it’s hard to drink less because it feels like something is missing, it’s probably because indeed something is missing, and this book can help you bridge that gap!

A Urologist Explains Edging: What, Why, & Is It Safe?
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
“Edging” is the practice of intentionally delaying orgasm, which can be enjoyed by anyone, with a partner or alone.
On the edge
Question: why?
Answer: the more tension is built up, the stronger the orgasm can be at the end of it. And, even before then, pleasure along the way is pleasure along the way, which is generally considered a good thing—especially for any (usually but not always women, for hormonal and social reasons) who find it difficult to orgasm. It’s also a great way to experiment and learn more about one’s own body and/or that of one’s partner(s), personal responses, and so forth. Also, for any (usually but not always men, for hormonal reasons) who find they usually orgasm sooner than they’d like, it’s a great way to change that, if changing that is what’s wanted.
Bonus answer: for some (usually but not always men, for hormonal reasons) who find they have an uncomfortable slump in mood after orgasm, that can simply be skipped entirely, postponed for another time, etc, with pleasure being derived from the sexual activity rather than orgasm. That way, there’s a lasting dopamine high, with no prolactin crash afterwards ← this is very much tied to male hormones, by the way. If you have female hormones, there’s usually no prolactin crash either way, and instead, the post-orgasm spike in oxytocin is stronger, and a wave of serotonin makes the later decline of dopamine much more gentle.
Question: can it cause any problems?
Answer: yep! Or rather, subjectively, it may be considered so—this is obviously a personal matter and your mileage may vary. The main problem it may cause is that if practised habitually, it may result in greater difficulty achieving orgasm, simply because the body has got used to “ok, when we do this (sex/masturbation), we are in no particular rush to do that (orgasm)”. So whether not this would be a worry for you is down to any given individual. Lastly, if your intent was a long edging session with an orgasm at the end and then something happened to interrupt that, then your orgasm may be unintentionally postponed to another time, which again, may be more or less of an issue depending on your feelings about that.

The Art of Being Unflappable (Tricks For Daily Life)
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
The Art of Being Unflappable
From Stoicism to CBT, thinkers through the ages have sought the unflappable life.
Today, in true 10almonds fashion, we’re going to distil it down to some concentrated essentials that we can all apply in our daily lives:
Most Common/Impactful Cognitive Distortions To Catch (And Thus Avoid)
These are like the rhetorical fallacies with which you might be familiar (ad hominem, no true Scotsman, begging the question, tu quoque, straw man, etc), but are about what goes on between your own ears, pertaining to your own life.
If we learn about them and how to recognize them, however, we can catch them before they sabotage us, and remain “unflappable” in situations that could otherwise turn disastrous.
Let’s take a look at a few:
Catastrophizing / Crystal Ball
- Distortion: not just blowing something out of proportion, but taking an idea and running with it to its worst possible conclusion. For example, we cook one meal that’s a “miss” and conclude we are a terrible cook, and in fact for this reason a terrible housewife/mother/friend/etc, and for this reason everyone will probably abandon us and would be right to do so
- Reality: by tomorrow, you’ll probably be the only one who even remembers it happened
Mind Reading
- Distortion: attributing motivations that may or may not be there, and making assumptions about other people’s thoughts/feelings. An example is the joke about two partners’ diary entries; one is long and full of feelings about how the other is surely dissatisfied in their marriage, has been acting “off” with them all day, is closed and distant, probably wants to divorce, may be having an affair and is wondering which way to jump, and/or is just wondering how to break the news—the other partner’s diary entry is short, and reads “motorcycle won’t start; can’t figure out why”
- Reality: sometimes, asking open questions is better than guessing, and much better than assuming!
All-or-Nothing Thinking / Disqualifying the Positive / Magnifying the Negative
- Distortion: having a negative bias that not only finds a cloud in every silver lining, but stretches it out so that it’s all that we can see. In a relationship, this might mean that one argument makes us feel like our relationship is nothing but strife. In life in general, it may lead us to feel like we are “naturally unlucky”.
- Reality: those negative things wouldn’t even register as negative to us if there weren’t a commensurate positive we’ve experienced to hold them in contrast against. So, find and remember that positive too.
For brevity, we put a spotlight on (and in some cases, clumped together) the ones we think have the most bang-for-buck to know about, but there are many more.
So for the curious, here’s some further reading:
