What Your Mucus Says About Your Health

It’s not a sexy topic (unless perhaps you have a fetish), but it is a useful topic to know about.
So, let’s get down to business with this much-maligned bodily fluid:
What is mucus? And why?
Sometimes, it can seem that mucus only exists to be an inconvenience, and to convey disease.
And… Actually, that’s mostly true.
While some kinds of mucus have other jobs beyond the scope of today’s article (did you know semen is mostly mucus? If not, now you do), the primary job of most of our mucus is to stop things (especially pathogens) going where they shouldn’t.
So, in essence, it really does exist to be an inconvenience—to pathogens. And to convey those pathogens to where they can be disposed of safely, either outside of the body, or to be an easy meal (what with being stuck in mucus, and thus at least moderately immobilized) for our various active immune cells. To make matters worse for the pathogens, there are (usually) enzymes in our mucus that have antimicrobial properties, too.
Some of mucus’s protective role can be in other ways too, such as by lining our stomach. You know, the stomach that contains the acid that can dissolve meat, despite us also being made of meat.
The slimiest rainbow
Ok, maybe not the slimiest rainbow—there’s probably a YouTube slime channel producing more colors. But, our noses are capable of dispensing astonishing quantities of mucus sometimes, and the color can vary widely, so here’s what we can know from that:
Clear
This is as it should be, in good health. If you’re getting lots of it but it’s clear, then it’s usually allergies, but watch out in case it changes color, heralding an infection. This “clear is how it looks when in ideal health”, by the way, is why when someone is sobbing in abject grief, any mucus that shows up to add to that picture will generally be clear.
White
As above, but now inflamed. Inflammation is usually something we don’t want, but in the case of a threat from a pathogen, we actually do want acute inflammation like this—the body is assembling its armies, of which, the most visible (when they appear in mass) are white blood cells. Because of their abundant presence at this stage, the mucus will also become thicker.
Yellow
As above, but the battle is now truly underway, and the yellow color comes from dead white blood cells. This does not, however, mean the battle is necessarily going badly—the body treats its white blood cells as very disposable fighters, and their deaths in large numbers are expected and normal when doing battle.
Green
As above, but neutrophils (a specific kind of white blood cell) have joined the party. They release an enzyme that colors the mucus green—and kills a lot of pathogens. Popular lore says that green mucus means a bacterial infection, but it’s not always so; these can be deployed against viruses too, depending on various factors beyond the scope of this article (but generally pertaining to severity). In any case, this too does not mean the battle is necessarily going badly, but it does express that your body is taking it very seriously—and you should, too.
Red
Nothing to do with infections, usually—it’s just a little blood (the red kind, this time). Usually it got into the mucus because the mucus membrane got damaged, usually due to some kind of physical trauma (e.g. very vigorous nose-blowing, poking things up the nose, etc) or sometimes if the air is very dry (then the mucus itself can dry out, and become stabby inside the nose; when more mucus is produced, it gets infused with blood from the injury).
Pink
As above, but combined with the “white” stage of infection response.
Orange
As above, but combined with the “yellow” stage of infection response.
Brown
As above, but the blood has oxidized—or, as a completely alterative possibility, it could mean you have been breathing a lot of pollutants. Smoke of various kinds (from fires, from smoking, etc) can cause this.
Black
There are various possible explanations here and all of them are bad. Get thee to a doctor. Superficial examples include:
- Fungal infection (you thought toxic black mold was bad when it was on the wall of the house, wait until it’s on the walls of your respiratory system)
- Blood, in abundance, oxidized (which begs the question of what caused that, but certainly: something wrong is not right)
- Pollutants again, but this time at absurd levels of exposure
That last one might sound very transient and self-correcting, but it’s not, and it comes with many increased short- and long-term health risks.

Grapes vs Strawberries – Which is Healthier?
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.
Our Verdict
When comparing strawberries to grapes, we picked the strawberries.
Why?
In terms of macros, grapes have more than 2x the carbs while strawberries have more than 2x the fiber, making this category an easy win for strawberries.
In the category of vitamins, grapes have more of vitamins A, B1, B2, B6, and K, while strawberries have more of vitamins B3, B5, B9, C, and E, making for a 5:5 tie with comparable margins of difference.
Looking at minerals, grapes have more potassium and manganese, while strawberries have more calcium, copper, iron, magnesium, phosphorus, selenium, and zinc. A clear win for strawberries here.
When it comes to polyphenols, both of these fruits are abundant in many polyphenols, but it might interest you to know that strawberries have slightly more resveratrol than red/black grapes! Still, it’s close, and there are many other polyphenols in both, and honestly we’re calling this category a tie.
Adding up the sections makes for a compelling overall win for strawberries, but by all means enjoy either or both; diversity is good!

How to Fall Asleep Faster: CBT-Insomnia Treatment
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.
Insomnia affects a lot of people, and is even more common as we get older. Happily, therapist Emma McAdam is here with a drug-free solution that will work for most people most of the time.
Cognitive Behavioral Therapy for Insomnia (CBTI)
While people think of causes of insomnia as being things such as stress, anxiety, overthinking, disturbances, and so forth, these things affect sleep in the short term, but don’t directly cause chronic insomnia.
We say “directly”, because chronic insomnia is usually the result of the brain becoming accustomed to the above, and thus accidentally training itself to not sleep.
The remedy: cut the bad habit of staying in bed while awake. Lying in bed awake trains the brain to associate lying in bed with wakefulness (and any associated worrying, etc). In essence, we lie down, and the brain thinks “Aha, we know this one; this is the time and place for worrying, ok, let’s get to work”.
So instead: if you’re in bed and not asleep within 15 minutes, get up and do something non-stimulating until you feel sleepy, then return to bed. This may cause some short term tiredness, but it will usually correct the chronic insomnia within a week.

What’s the difference between heat exhaustion and heat stroke? One’s a medical emergency
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.
When British TV doctor Michael Mosley died last year in Greece after walking in extreme heat, local police said “heat exhaustion” was a contributing factor.
Since than a coroner could not find a definitive cause of death but said this was most likely due to an un-identified medical reason or heat stroke.
Heat exhaustion and heat stroke are two illnesses that relate to heat.
So what’s the difference?
Studio Nut/Shutterstock A spectrum of conditions
Heat-related illnesses range from mild to severe. They’re caused by exposure to excessive heat, whether from hot conditions, physical exertion, or both. The most common ones include:
- heat oedema: swelling of the hands, feet and ankles
- heat cramps: painful, involuntary muscle spasms usually after exercise
- heat syncope: fainting due to overheating
- heat exhaustion: when the body loses water due to excessive sweating, leading to a rise in core body temperature (but still under 40°C). Symptoms include lethargy, weakness and dizziness, but there’s no change to consciousness or mental clarity
- heat stroke: a medical emergency when the core body temperature is over 40°C. This can lead to serious problems related to the nervous system, such as confusion, seizures and unconsciousness including coma, leading to death.
As you can see from the diagram below, some symptoms of heat stroke and heat exhaustion overlap. This makes it hard to recognise the difference, even for medical professionals.
CC BY-SA How does this happen?
The human body is an incredibly efficient and adaptable machine, equipped with several in-built mechanisms to keep our core temperature at an optimal 37°C.
But in healthy people, regulation of body temperature begins to break down when it’s hotter than about 31°C with 100% humidity (think Darwin or Cairns) or about 38°C with 60% humidity (typical of other parts of Australia in summer).
This is because humid air makes it harder for sweat to evaporate and take heat with it. Without that cooling effect, the body starts to overheat.
Once the core temperature rises above 37°C, heat exhaustion can set in, which can cause intense thirst, weakness, nausea and dizziness.
If the body heat continues to build and the core body temperature rises above 40°C, a much more severe heat stroke could begin. At this point, it’s a life-threatening emergency requiring immediate medical attention.
At this temperature, our proteins start to denature (like an egg on a hotplate) and blood flow to the intestines stops. This makes the gut very leaky, allowing harmful substances such as endotoxins (toxic substances in some bacteria) and pathogens (disease causing microbes) to leak into the bloodstream.
The liver can’t detoxify these fast enough, leading to the whole body becoming inflamed, organs failing, and in the worst-case scenario, death.
Who’s most at risk?
People doing strenuous exercise, especially if they’re not in great shape, are among those at risk of heat exhaustion or heat stroke. Others at risk include those exposed to high temperatures and humidity, particularly when wearing heavy clothing or protective gear.
Outdoor workers such as farmers, firefighters and construction workers are at higher risk too. Certain health conditions, such as diabetes, heart disease, or lung conditions (such as COPD or chronic obstructive pulmonary disease), and people taking blood pressure medications, can also be more vulnerable.
Adults over 65, infants and young children are especially sensitive to heat as they are less able to physically cope with fluctuations in heat and humidity.
Firefighters are among those at risk of heat-related illness. structuresxx/Shutterstock How are these conditions managed?
The risk of serious illness or death from heat-related conditions is very low if treatment starts early.
For heat exhaustion, have the individual lie down in a cool, shady area, loosen or remove excess clothing, and cool them by fanning, moistening their skin, or immersing their hands and feet in cold water.
As people with heat exhaustion almost always are dehydrated and have low electrolytes (certain minerals in the blood), they will usually need to drink fluids.
However, emergency hospital care is essential for heat stroke. In hospital, health professionals will focus on stabilising the patient’s:
- airway (ensure no obstructions, for instance, vomit)
- breathing (look for signs of respiratory distress or oxygen deprivation)
- circulation (check pulse, blood pressure and signs of shock).
Meanwhile, they will use rapid-cooling techniques including immersing the whole body in cold water, or applying wet ice packs covering the whole body.
Take home points
Heat-related illnesses, such as heat stroke and heat exhaustion, are serious health conditions that can lead to severe illness, or even death.
With climate change, heat-related illness will become more common and more severe. So recognising the early signs and responding promptly are crucial to prevent serious complications.

How Stress Affects Your Body
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.
Dr. Sharon Bergquist gives us a tour:
Stress, from the inside out
Stress is a natural physical and emotional response to challenges or being overwhelmed. It can be beneficial in short-term situations (e.g. escape from a tiger) but is harmful when prolonged or frequent (e.g. escape the rat-race).
Immediate physiological response: cortisol, adrenaline (epinephrine), and norepinephrine are released by the adrenal glands.
The effects this has (non-exhaustive list; we’re just citing what’s in the video here):
- Cortisol impairs blood vessel function, promoting atherosclerosis.
- Adrenaline increases heart rate and blood pressure, leading to hypertension.
- Stress disrupts the brain-gut connection, causing:
- Digestive issues like irritable bowel syndrome and heartburn.
- Changes in gut bacteria composition, potentially affecting overall health.
- Cortisol increases appetite and cravings for energy-dense “comfort foods”.
- This in turn promotes visceral fat storage, which raises the risk of heart disease and insulin resistance.
- Immune-specific effects:
- Stress hormones initially aid in healing and immune defense.
- Chronic stress weakens immune function (by over-working it constantly), increasing susceptibility to infections and slowing recovery.
- Other systemic effects:
- Chronic stress shortens telomeres, which protect chromosomes. Shortened telomeres accelerate cellular aging.
- Chronic stress can also cause acne, hair loss, sexual dysfunction, headaches, muscle tension, fatigue, irritability, and difficulty concentrating.
So, how to manage this? The video says that viewing stressful situations as controllable challenges, rather than insurmountable threats, leads to better short-term performance and long-term health.
Which would be wonderful, except that usually things are stressful precisely because they are not entirely within the field of our control, and the usual advice is to tend to what we can control, and accept what we can’t.
However… That paradigm still leaves out the very big set of “this might be somewhat within our control or it might not; we really don’t know yet; we can probably impact it but what if we don’t do enough, or take the wrong approach and do the wrong thing? And also we have 17 competing stressors, which ones should we prioritize tending to first, and…” and so on.
To that end, we suggest checking out the “Want to learn more?” link we drop below the video today, as it is about managing stress realistically, in a world that, if we’re honest about it, can sometimes be frankly unmanageable.

Here’s how to help protect your family from norovirus
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 you need to know
- Norovirus is a very contagious infection that causes vomiting and diarrhea.
- The best way to help protect against norovirus is to wash your hands often with soap and warm water, since hand sanitizer may not be effective at killing the virus.
- If someone in your household has symptoms of norovirus, isolate them away from others, watch for signs of dehydration, and take steps to help prevent it from spreading.
If you feel like everyone is sick right now, you’re not alone. Levels of respiratory illnesses like COVID-19, flu, and RSV remain remain high in many states, and the U.S. is also battling a wave of norovirus, one of several viruses that cause a very contagious infection of the stomach and intestines.
Although norovirus infections are more common during the colder months—it’s also called the “winter vomiting disease”—the virus can spread at any time. Right now, however, cases have more than doubled since last year’s peak.
Read on to learn about the symptoms of norovirus, how it spreads, and what to do if someone in your household gets sick.
What are the symptoms of norovirus?
Norovirus is a very contagious infection that causes vomiting and diarrhea, which typically begins 12 to 48 hours after exposure to the virus. Additional symptoms may include stomach pain, body aches, headaches, and a fever. Norovirus typically resolves within three days, but people who are infected may still be contagious for up to two days after symptoms resolve.
Norovirus may cause dehydration, or a dangerous loss of fluids, especially in young children and older adults. See a health care provider if you or someone in your household shows signs of dehydration, which may include decreased urination, dizziness, a dry mouth and throat, sleepiness, and crying without tears.
How can you help protect against norovirus?
You can get norovirus if you have close contact with someone who is infected, touch a contaminated surface and then touch your mouth or nose, or consume contaminated food or beverages.
The best way to help protect yourself and others against norovirus is to wash your hands often with soap and warm water, since hand sanitizer may not be effective at killing the virus. Other ways to help protect yourself may include cooking food thoroughly and washing fruits and vegetables before eating them.
You can get sick with norovirus even if you’ve had it before, since there are many different strains.
How can families help protect against the spread of norovirus at home?
If someone in your household has symptoms of norovirus, isolate them away from others and watch for signs of dehydration. If you are sick with norovirus, do not prepare food for others in your household and use a separate bathroom, if possible.
When cleaning up after someone who has norovirus, wear rubber, latex, or nitrile gloves. Then wash your hands thoroughly.
Clean surfaces using a solution containing five to 25 tablespoons of bleach (that’s 12.5 fluid ounces, or just over ¾ cup), per gallon of water. Leave the bleach-water mix on surfaces for at least five minutes before wiping it off.
For more information, talk to your health care provider.
