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.

The Alzheimer’s Gut-Brain Connection—Caught On X-Ray!
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.
We’ve written before about Alzheimer’s disease (a lot), and if you’re just joining us, then a great place to start is here:
How To Reduce Your Alzheimer’s Risk
We’ve also written about gut health (a lot), and if you’re just joining us, then a great place to start is here:
Make Friends With Your Gut! (Here’s Why & How)
And as a hat trick, yes, we’ve also written (admittedly not as much) about the gut-brain connection; here’s a primer:
The Brain-Gut Highway: A Two-Way Street
Because of how gut microbes influence brain function, behavior, and cognition, scientists wondered whether one’s microbiome might play a role in Alzheimer’s development. Recently, scientists from Italy’s Institute of Nanotechnology, working with the European Synchrotron Radiation Facility (ESRF), found some concrete answers:
How gut health affects Alzheimer’s
When the gut loses its healthy balance of bacteria, harmful bacteria (and fungi, like C. albicans, also popularly called by its first name, “Candida”) take the wheel. This problem (called “dysbiosis”) allows harmful microbes to produce toxic substances, leading to inflammation and weakening the protective barriers between the gut and brain.
In some cases, like the aforementioned C. albicans, they’ll even put roots through your gut wall (and interact with your nervous system, and they are a common reason for sugar and alcohol cravings—your CNS has literally been hacked by a fungal colony that wants sugar (including the sugar that occurs when alcohol is broken down—and that’s without considering the fact that alcohol also kills several of C. albicans competitors that rank amongst the “good bacteria”). Suffice it to say, the holes it puts in your gut wall aren’t great for the health either.
In any case, once the gut barrier is breached, it’s been hypothesized that harmful bacteria may even travel to the brain, triggering Alzheimer’s.
How the x-rays helped
To better understand gut changes in Alzheimer’s, scientists used a technique called nano- and micro- x-ray phase-contrast tomography (XPCT) at the aforementioned ESRF. That very fancy string of words refers to a commensurately powerful imaging method, which allows researchers to see detailed structures inside the gut without damaging tissue, or even adding contrast agents (like those unpleasant drinks that are sometimes required to be taken before soft-tissue x-rays).
The study examined gut samples from mice with Alzheimer’s (so yes, this does need to be repeated with humans, but in this case there’s no obvious reason why it shouldn’t be the same).
The scans revealed important changes in gut structures, including:
- The tiny finger-like villi and corresponding crypts in the gut lining
- Important cells* that help with digestion and protection
- Neurons involved in gut function
*e.g. Paneth cells, goblet cells, telocytes, and erythrocytes, all of whom would take more explanation than we have room for here, but suffice it to say they’re important to both digestion and correct mucus production (bearing in mind, mucus membranes are one of the main physical barriers to harmful bacteria—as humans, our conscious interactions with mucus are usually only the nuisance that occurs when we get a cold or something, but rest assured, mucus keeps us alive).
In short, all these findings suggest (we’d say “show”, but technically cause and effect have not been proven) gut health indeed plays a crucial role in Alzheimer’s disease pathogenesis and pathology (i.e., how the disease begins and progresses, respectively).
Why it matters
To quote Dr. Alessia Cedola,
❝This technique represents a real breakthrough for the thorough analysis of the gut, and it could be pivotal in early detection and prognosis of the disease.
By gaining a deeper understanding of these processes, we hope to identify new therapeutic targets and develop innovative treatments for this devastating disease.❞
In short: the technology can be used as a super-early diagnostic tool, and ultimately, improve prevention (by encouraging people to focus on gut health) as well as, hopefully, leading to new treatments, too.
Want to see it?
Here’s the paper itself, where there are also abundant very clear images:
Are you on top of your gut health already?
If not, do refer back to that first link we dropped about gut health, up top!
If you are already sure you’re looking after your gut and want to do something else to avoid Alzheimer’s coming to call, you might want to consider:
How To Clean Your Brain (Glymphatic Health Primer) ← your glymphatic system, something many people neglect, is the brain’s cleanup crew, and removes things like the beta-amyloid proteins that are implicated in Alzheimer’s pathogenesis. So, it’s worth knowing how to keep it in working order!

Why You Probably Need More Sleep
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.
Sleep: yes, you really do still need it!
We asked you how much sleep you usually get, and got the above-pictured, below-described set of responses:
- A little of a third of all respondents selected the option “< 7 hours”
- However, because respondents also selected options such as < 6 hours, < 5 hours, and < 4 hours, so if we include those in the tally, the actual total percentage of respondents who reported getting under 7 hours, is actually more like 62%, or just under two thirds of all respondents.
- Nine respondents, which was about 5% of the total, reported usually getting under 4 hours sleep
- A little over quarter of respondents reported usually getting between 7 and 8 hours sleep
- Fifteen respondents, which was a little under 10% of the total, reported usually getting between 8 and 9 hours of sleep
- Three respondents, which was a little under 2% of the total, reported getting over 9 hours of sleep
- In terms of the classic “you should get 7–9 hours sleep”, approximately a third of respondents reported getting this amount.
You need to get 7–9 hours sleep: True or False?
True! Unless you have a (rare!) mutated ADRB1 gene, which reduces that.
The way to know whether you have this, without genomic testing to know for sure, is: do you regularly get under 6.5 hours sleep, and yet continue to go through life bright-eyed and bushy-tailed? If so, you probably have that gene. If you experience daytime fatigue, brain fog, and restlessness, you probably don’t.
About that mutated ADRB1 gene:
NIH | Gene identified in people who need little sleep
Quality of sleep matters as much as duration, and a lot of studies use the “RU-Sated” framework, which assesses six key dimensions of sleep that have been consistently associated with better health outcomes. These are:
- regularity / usual hours
- satisfaction with sleep
- alertness during waking hours
- timing of sleep
- efficiency of sleep
- duration of sleep
But, that doesn’t mean that you can skimp on the last one if the others are in order. In fact, getting a good 7 hours sleep can reduce your risk of getting a cold by three or four times (compared with six or fewer hours):
Behaviorally Assessed Sleep and Susceptibility to the Common Cold
^This study was about the common cold, but you may be aware there are more serious respiratory viruses freely available, and you don’t want those, either.
Napping is good for the health: True or False?
True or False, depending on how you’re doing it!
If you’re trying to do it to sleep less in total (per polyphasic sleep scheduling), then no, this will not work in any sustainable fashion and will be ruinous to the health. We did a Mythbusting Friday special on specifically this, a while back:
Could Just Two Hours Sleep Per Day Be Enough?
PS: you might remember Betteridge’s Law of Headlines
If you’re doing it as a energy-boosting supplement to a reasonable night’s sleep, napping can indeed be beneficial to the health, and can give benefits such as:
- Increased alertness
- Helps with learning
- Improved memory
- Boost to immunity
- Enhance athletic performance
However! There is still a right and a wrong way to go about it, and we wrote about this previously, for a Saturday Life Hacks edition of 10almonds:
How To Nap Like A Pro (No More “Sleep Hangovers”!)
As we get older, we need less sleep: True or False
False, with one small caveat.
The small caveat: children and adolescents need 9–12 hours sleep because, uncredited as it goes, they are doing some seriously impressive bodybuilding, and that is exhausting to the body. So, an adult (with a normal lifestyle, who is not a bodybuilder) will tend to need less sleep than a child/adolescent.
But, the statement “As we get older, we need less sleep” is generally taken to mean “People in the 65+ age bracket need less sleep than younger adults”, and this popular myth is based on anecdotal observational evidence: older people tend to sleep less (as our survey above shows! For any who aren’t aware, our readership is heavily weighted towards the 60+ demographic), and still continue functioning, after all.
Just because we survive something with a degree of resilience doesn’t mean it’s good for us.
In fact, there can be serious health risks from not getting enough sleep in later years, for example:
Sleep deficiency promotes Alzheimer’s disease development and progression
Want to get better sleep?
What gets measured, gets done. Sleep tracking apps can be a really good tool for getting one’s sleep on a healthier track. We compared and contrasted some popular ones:

Lemon vs Lime – 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 lemons to limes, we picked the lemons.
Why?
This one’s simple today. They’re both comparable fruits in most ways, and their macro profiles are almost identical. When it comes to vitamins, however, they stand apart a little.
Both are most well-known for their vitamin C content, but lemons contain about 2x the vitamin C of limes.
In other vitamins, they’re not too far apart. Technically limes have 2x the vitamin A, but this doesn’t count for much because it’s a case of “two times almost nothing is still almost nothing”.
In the category of minerals, neither fruit is a very good source of most minerals, and the minerals they do have, are mostly more or less the same.
Both are acidic, and this can have blood sugar benefits in both cases (and, if not careful, damage tooth enamel in both cases). Nothing to set either apart from the other here.
So, it comes down to the vitamin C! In which category, lemons take the prize with their higher content.

Genital herpes is on the rise. Here’s what to know about this common infection
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 World Health Organization (WHO) recently released new estimates suggesting around 846 million people aged between 15 and 49 live with a genital herpes infection.
That’s equivalent to one in every five people from that age group.
At least one person each second (42 million people annually) contracts a new genital herpes infection.
So what is genital herpes, and are cases on the rise? Here’s what to know about this common infection.
Peakstock/Shutterstock First, what causes genital herpes?
Genital herpes is a sexually transmitted infection (STI) caused by the herpes simplex virus, which also causes cold sores.
There are two types of herpes simplex virus, HSV-1 and HSV-2 (and it’s possible to be infected by both at the same time).
HSV-1 most commonly spreads through oral contact such as kissing or sharing infected objects such as lip balm, cups or utensils, and presents as cold sores (or oral herpes) around the mouth. But it can also be sexually transmitted to cause a genital herpes infection.
An estimated 3.8 billion people under the age of 50 (64%) globally have HSV-1.
HSV-2 is less prevalent, but almost always causes a genital herpes infection. Some 520 million people aged 15–49 (13%) worldwide are believed to have HSV-2.
The initial episode of genital herpes can be quite painful, with blisters, ulcers and peeling skin around the genitals over 7–10 days.
Not all people have severe (or any) initial symptoms. This means a person might not know they have been infected with a herpes virus.
Herpes is a lifelong infection, which means once you contract the virus, you have it forever. After an initial episode, subsequent episodes can occur, but are usually less painful or even symptom free.
Both oral and genital herpes are particularly easy to spread when you have active lesions (cold sores or genital ulcers). But even with no symptoms, herpes can still be spread to a partner.
And although relatively rare, oral herpes can be transmitted to the genital area, and genital herpes can be transmitted to the mouth through oral sex.
If an expectant mother exhibits a genital herpes infection close to childbirth, there are risks to the baby. A herpes infection can be very serious in a baby, and the younger the infant, the more vulnerable they are. This is also one reason why you should avoid kissing a baby on the mouth.
Changing trends
WHO’s recent figures brought together data from around the world to estimate the prevalence of genital herpes in 2020, compared with previous estimates in 2012 and 2016.
This data shows no significant difference in the prevalence of genital herpes caused by HSV-2 since 2016, but does highlight increases in genital herpes infections caused by HSV-1.
The estimated number of genital HSV-1 infections globally was nearly twice as high in 2020 compared with 2016 (376 million compared with 192 million).
A 2022 study looking at Australia, New Zealand and Canada found more than 60% of genital herpes infections are still caused by HSV-2. But this is declining by about 2% each year while new genital infections that result from HSV-1 are rising.
Genital herpes can be quite painful, presenting as sores and lesions that in severe cases, may take up to a month to fully heal. Christian Moro There’s no simple fix, but safe sex is important
Genital herpes causes a substantial disease burden and economic cost to health-care services.
With such a large proportion of the world’s population infected with HSV-1, evidence this virus is increasingly causing genital herpes is concerning.
There’s no cure for genital herpes, but some medications, such as antivirals, can help reduce the amount of virus present in the system. While this won’t kill it completely, it helps to prevent symptomatic genital herpes recurrences, improve quality of life, and minimise the risk of transmission.
To prevent the spread of genital herpes and other STIs, practise safe sex, particularly if you’re not sure of your partner’s sexual health. You need to use a barrier method such as condoms to protect against STIs (a contraceptive such as the pill won’t work). This includes during oral sex.
As herpes is now so common, testing is not usually included as part of a regular sexual health check-up, except for in specific circumstances such as during pregnancy or severe episodes.
So it’s wise not to let your guard down, even if your partner insists they have received the all-clear from a recent check-up.
If there are herpes lesions present around the genitals, avoid sex entirely. Even condoms are not fully effective at these times, as exposed areas can still transmit the infection.
Practising safe sex can help prevent the spread of herpes. cottonbro studio/Pexels Immune health
If you are infected with HSV-1 or HSV-2 it’s more likely symptoms will appear when you’re stressed, tired or overwhelmed. During these times, our immune system may not be as functional, and dormant viruses such as herpes can start to develop quickly in our bodies.
To reduce the risk of recurrent herpes infections, try to eat healthily, get at least seven hours of sleep each night if possible, and look out for when your body may be telling you to take a step back and relax. This self-care can go a long way towards keeping latent viruses at bay.
While the prevalence has increased significantly in recent years, we have not lost the war on genital herpes just yet. Safe sexual practices, education and awareness can help reduce its spread, and the stigma around it.
If you have personal concerns, you should discuss them with a medical professional.

Older, Faster, Stronger – by Margaret Webb
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 author, now in her 60s, made it her mission in her 50s to become the best runner she could. Before that, she’d been a keen runner previously, but let things slip rather in her 40s. But the book’s not about her 40s, it’s about her 50s and onwards, and other female runners in their 50s, 60s, 70s, 80s, and even 90s.
There’s a lot of this book that’s about people’s individual stories, and those should certainly be enough to prompt almost any reader that “if they can do it, I can”.
A lot, meanwhile, is about health and exercise science, training methods, and what has worked for various later-life athletes, including the author. So, it’s also partway instruction manual, with plenty of reference to science and medical considerations too.
Bottom line: sometimes, life throws us challenges. Sometimes, the best response is “Yeah? Bet” and surprise everyone.
