What causes the itch in mozzie bites? And why do some people get such a bad reaction?

Are you one of these people who loathes spending time outdoors at dusk as the weather warms and mosquitoes start biting?
Female mosquitoes need blood to develop their eggs. Even though they take a tiny amount of our blood, they can leave us with itchy red lumps that can last days. And sometimes something worse.
So why does our body react and itch after being bitten by a mosquito? And why are some people more affected than others?
What happens when a mosquito bites?
Mosquitoes are attracted to warm blooded animals, including us. They’re attracted to the carbon dioxide we exhale, our body temperatures and, most importantly, the smell of our skin.
The chemical cocktail of odours from bacteria and sweat on our skin sends out a signal to hungry mosquitoes.
Some people’s skin smells more appealing to mosquitoes, and they’re more likely to be bitten than others.
Once the mosquito has made its way to your skin, things get a little gross.
The mosquito pierces your skin with their “proboscis”, their feeding mouth part. But the proboscis isn’t a single, straight, needle-like tube. There are multiple tubes, some designed for sucking and some for spitting.
Once their mouth parts have been inserted into your skin, the mosquito will inject some saliva. This contains a mix of chemicals that gets the blood flowing better.
There has even been a suggestion that future medicines could be inspired by the anti-blood clotting properties of mosquito saliva.
It’s not the stabbing of our skin by the mosquito’s mouth parts that hurts, it’s the mozzie spit our bodies don’t like.
Are some people allergic to mosquito spit?
Once a mosquito has injected their saliva into our skin, a variety of reactions can follow. For the lucky few, nothing much happens at all.
For most people, and irrespective of the type of mosquito biting, there is some kind of reaction. Typically there is redness and swelling of the skin that appears within a few hours, but often more quickly, after just a few minutes.
Occasionally, the reaction can cause pain or discomfort. Then comes the itchiness.
Some people do suffer severe reactions to mosquito bites. It’s a condition often referred to as “skeeter syndrome” and is an allergic reaction caused by the protein in the mosquito’s saliva. This can cause large areas of swelling, blistering and fever.
The chemistry of mosquito spit hasn’t really been well studied. But it has been shown that, for those who do suffer allergic reactions to their bites, the reactions may differ depending on the type of mosquito biting.
We all probably get more tolerant of mosquito bites as we get older. Young children are certainly more likely to suffer more following mosquito bites. But as we get older, the reactions are less severe and may pass quickly without too much notice.
How best to treat the bites?
Research into treating bites has yet to provide a single easy solution.
There are many myths and home remedies about what works. But there is little scientific evidence supporting their use.
The best way to treat mosquito bites is by applying a cold pack to reduce swelling and to keep the skin clean to avoid any secondary infections. Antiseptic creams and lotions may also help.
There is some evidence that heat may alleviate some of the discomfort.
It’s particularly tough to keep young children from scratching at the bite and breaking the skin. This can form a nasty scab that may end up being worse than the bite itself.
Applying an anti-itch cream may help. If the reactions are severe, antihistamine medications may be required.
To save the scratching, stop the bites
Of course, it’s better not to be bitten by mosquitoes in the first place. Topical insect repellents are a safe, effective and affordable way to reduce mosquito bites.
Covering up with loose fitted long sleeved shirts, long pants and covered shoes also provides a physical barrier.
Mosquito coils and other devices can also assist, but should not be entirely relied on to stop bites.
There’s another important reason to avoid mosquito bites: millions of people around the world suffer from mosquito-borne diseases. More than half a million people die from malaria each year.
In Australia, Ross River virus infects more than 5,000 people every year. And in recent years, there have been cases of serious illnesses caused by Japanese encephalitis and Murray Valley encephalitis viruses.

Managing Chronic Pain (Realistically!)
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.
Realistic chronic pain management
We’ve had a number of requests to do a main feature on managing chronic pain, so here it is!
A quick (but important) note before we begin:
Obviously, not all chronic pain is created equal. Furthermore, we know that you, dear reader with chronic pain, have been managing yours for however long you have, learning as you go. You also doubtlessly know your individual condition inside out.
We also know that people with chronic health conditions in general are constantly beset by well-meaning unsolicited advice from friends and family, asking if you’ve heard about [thing you heard about 20 years ago] that will surely change your life and cure you overnight.
It’s frustrating, and we’re going to try to avoid doing that here, while still offering the advice that was asked for. We ask you, therefore, to kindly overlook whatever you already knew, and if you already knew it all, well, we salute you and will not be surprised if that’s the case for at least some readers. Chronic pain’s a… Well, it’s a chronic pain.
All that said, let’s dive in…
How are you treating your body right now?
Are you hydrated; have you eaten; are you standing/sitting/lying in a position that at least should be comfortable for you in principle?
The first two things affect pain perception; the latter can throw a spanner in the works if something’s not quite right.
Move your body (gently!)
You know your abilities, so think about the range of motion that you have, especially in the parts of your body that hurt (if that’s “everywhere”, then, our sympathies, and we hope you find the same advice applies). Think about your specific muscles and joints as applicable, and what the range of motion is “supposed” to be for each. Exercise your range of motion as best you can (gently!) to the point of its limit(s) and/or pain.
- If you take it past that limit, there is a good chance you will make it worse. You don’t want that.
- If you don’t take it to the limit, there is a good chance your range of movement will deteriorate, and your “safe zone” (i.e., body positions that are relatively free from pain) will diminish. You definitely don’t want that, either.
Again, moderation is key. Yes, annoying as the suggestion may be, such things as yoga etc can help, if done carefully and gently. You know your limits; work with those, get rest between, and do what you can.
For most people this will at least help keep the pain from getting worse.
Hot & Cold
Both of these things could ease your pain… Or make it worse. There is an element of “try it and see”, but here’s a good general guide:
Here’s How to Choose Between Using Ice or Heat for Pain
Meditation… Or Distraction
Meditating really does help a lot of people. In the case of pain, it can be counterintuitively helpful to focus for a while on the sensation of the pain… But in a calm, detached fashion. Without judgement.
“Yes, I am experiencing pain. Yes, it feels like I’m being stabbed with hot knives. Yes, this is tortuous; wow, I feel miserable. This truly sucks.”
…it doesn’t sound like a good experience, does it? And it’s not, but paying it attention this way can paradoxically help ease things. Pain is, after all, a messenger. And in the case of chronic pain, it’s in some ways a broken messenger, but what a messenger most needs is to be heard.
The above approach a) is good b) may have a limit in how long you can sustain it at a time, though. So…
The opposite is a can be a good (again, short-term) approach too. Call a friend, watch your favorite movie, play a video game if that’s your thing. It won’t cure anything, but it can give you a little respite.
Massage
Unless you already know this makes your pain worse, this is a good thing to try. It doesn’t have to be a fancy spa; if the nature of your pain and condition permits, you can do self-massage. If you have a partner or close friend who can commit to helping, it can be very worth them learning to give a good massage. There are often local courses available, and failing that, there is also YouTube.
Here’s an example of a good video for myofascial release massage, which can ease a lot of common kinds of chronic pain:
Some quick final things to remember:
- If you find something helps, then it helps, do that.
- That goes for mobility aids and other disability aids too, even if it was designed for a different disability. If it helps, it helps. You’re not stealing anyone’s thunder (or resources) by using something that makes your life easier. We’re not in this life to suffer!
- There is no such thing as “this pain is not too much”. The correct amount of pain is zero. Maybe your body won’t let you reach zero, but more than that is “too much” already.
- You don’t have to be suffering off the scale to deserve relief from pain

Chicken or Fish – 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 chicken to fish, we picked the fish.
Why?
To understand the choice, we have to start a bit earlier on the decision tree. For most people most of the time, when it comes to a diet high in plants or high in animals, the plant-centric diet will generally be best:
Do We Need Animal Products To Be Healthy?
When it comes to animal meats, red meat is a fairly uncontroversial first thing to strike off the list:
…with pork and some other meats not being much better.
But chicken? Poultry in general appears to be quite health-neutral. The jury is out and the science has mixed results, but the data is leaning towards “it’s probably fine”.
See for example this huge (n=29,682) study:
this same paper shows that…
❝higher intake of processed meat, unprocessed red meat, or poultry, but not fish, was significantly associated with a small increased risk of incident CVD, whereas higher intake of processed meat or unprocessed red meat, but not poultry or fish, was significantly associated with a small increased risk of all-cause mortality❞
So, since poultry isn’t significantly increasing all-cause mortality, and fish isn’t significantly increasing all-cause mortality or cardiovascular disease, fish comes out as the hands-down (fins-down?) winner.
One more (this time, easy) choice to make, though!
While fish in general (please, not fried, though!) is generally considered quite healthy, there is a big difference (more than you might think, and for reasons that are quite alarming), between…

Blueberries vs Banana – 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 blueberries to banana, we picked the banana.
Why?
Surprise, that which is more expensive is not always commensurately more healthy! A lot of the price difference between bananas and blueberries comes down to:
- ease of transport (unripe bananas can be transported quite easily without too much risk of bruising; unripe blueberries can’t even be usefully picked)
- shelf-life (unripe bananas will take their time to ripen; the already-ripe blueberries will often go bad very quickly)
For this reason, frozen blueberries are a great option for budget-friendly berries. But, onto the comparisons:
In terms of macros, bananas have slightly more protein, carbs, and fiber, and the slightly lower glycemic index. Really, both are good, but by the numbers, bananas win.
When it comes to vitamins, blueberries have more of vitamins B1, C, E, and K, while bananas have more of vitamins A, B2, B3, B5, B6, B9, and choline. Another win for bananas, though of course we could quibble which vitamins are most likely to be not found in sufficient abundance in the rest of one’s diet, but as it is, we just compared the nutrients head-to-head without trying to guess the rest of someone’s diet.
In the category of minerals, blueberries have more calcium and manganese, while bananas have more copper, magnesium, phosphorus, potassium, and selenium. Another win for bananas.
As for polyphenols, this is where blueberries shine, with a lot more than bananas (difficult to calculate exactly due to variations, but, in the order of hundreds of times more). A win for blueberries this time.
Adding up the section gives us an overall win for bananas, but by all means enjoy either or both; perhaps even together!

Nanotechnology vs Alcohol Damage!
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.
One Thing That Does Pair Well With Alcohol…
Alcohol is not a healthy thing to consume. That shouldn’t be a controversial statement, but there is a popular belief that it can be good for the heart:
Red Wine & The Heart: Can We Drink To Good Health?
The above is an interesting and well-balanced article that examines the arguments for health benefits (including indirectly, e.g. social aspects).
Ultimately, though, as the World Health Organization puts it:
WHO: No level of alcohol consumption is safe for our health
There is some good news:
We can somewhat reduce the harm done by alcohol by altering our habits slightly:
How To Make Drinking Less Harmful
…and we can also, of course, reduce our alcohol consumption (ideally to zero, but any reduction is an improvement already):
And, saving the best news (in this section, anyway) for last, it is almost always possible to undo the harm done specifically to one’s liver:
Nanotechnology to the rescue?
Remember when we had a main feature about how colloidal gold basically does nothing by itself (and that that’s precisely why gold is used in medicine, when it is used)?
Now it has an extra bit of nothing to do, for our benefit (if we drink alcohol, anyway), as part of a gel that detoxifies alcohol before it can get to our liver:
Gold is one of the “ingredients” in a gel containing a nanotechnology lattice of protein fibrils coated with iron (and the gold is there as an inert catalyst, which is chemistry’s way of saying it doesn’t react in any way but it does cheer the actual reagents on). There’s more chemistry going on than we have room to discuss in our little newsletter, so if you like the full details, you can read about that here:
Single-site iron-anchored amyloid hydrogels as catalytic platforms for alcohol detoxification
The short and oversimplified explanation is that instead of alcohol being absorbed from the gut and transported via the bloodstream to the liver, where it is metabolized (poisoning the liver as it goes, and poisoning the rest of the body too, including the brain), the alcohol is degraded while it is still in the gastrointestinal tract, converted by the gel’s lattice into acetic acid (which is at worst harmless, and actually in moderation a good thing to have).
Even shorter and even more oversimplified: the gel turns the alcohol into vinegar in the stomach and gut, before it can get absorbed into the blood.
But…
Of course there’s a “but”…
There are some limitations:
It doesn’t get it all (tests so far found it only gets about half of the alcohol), and so far it’s only been tested on mice, so it’s not on the market yet—while the researchers are sufficiently confident about it that a patent application has now been made, though, so it’ll probably show up on the market in the near future.
You can read a pop-science article about it (with diagrams!) here:
New gel breaks down alcohol in the body
Want to read more…
…about how to protect your organs (including your brain) from alcohol completely?
We’ve reviewed quite a number of books about quitting alcohol, so it’s hard to narrow it down to a single favorite, but after some deliberation, we’ll finish today with recommending:

Undoing Creatine’s Puffiness Side Effect
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 Q&A Day at 10almonds!
Have a question or a request? We love to hear from you!
In cases where we’ve already covered something, we might link to what we wrote before, but will always be happy to revisit any of our topics again in the future too—there’s always more to say!
As ever: if the question/request can be answered briefly, we’ll do it here in our Q&A Thursday edition. If not, we’ll make a main feature of it shortly afterwards!
So, no question/request too big or small 😎
❝Creatine is known to increase “puffiness”, especially in my face. Are there any supplements that do the opposite?!❞
So first, let’s examine why this happens: creatine is most often taken to boost muscle size and performance. Your muscles are, of course, mostly water by mass, and so building your muscles requires extra water, which triggers systemic water retention.
In other words: you take creatine, exercise, and as the muscles start growing, the body goes “oh heck, we are running out of water, better save as much as possible in order to keep hydrating the muscles without running out” and starts putting it anywhere it can that’s not your bladder, so this will largely be the soft tissues of your body.
So, this results in classic water retentions symptoms including bloating and, yes, facial puffiness.
How much this happens, and how long the effects last, depend on three main things:
- What daily dose of creatine you are taking
- What kind of exercise you are doing
- What your hydration is like
The dose is relevant as it’s most common to get this puffiness during the “loading” phase, i.e. if you’re taking an increased dose to start with.
The exercise is relevant as it affects how much your body is actually using the water to build muscles.
The hydration is relevant because the less water you are taking, the more the body will try to retain whatever you do have.
This means, of course, that the supplement you are looking for to undo the facial puffiness is, in fact, water (even, nay, especially, if you feel bloated too):
Water For Everything? Water’s Counterintuitive Properties
Additionally, you could scale back the dose of creatine you’re taking, if you’re not currently doing heavy muscle-building exercise.
That said, the recommended dose for cognitive benefits is 5g/day, which is a very standard main-phase (i.e., post-loading) bodybuilding dose, so do with that information what you will.
See also: Creatine’s Brain Benefits Increase With Age
On which note: whether or not you want to take creatine for brain benefits, however, may depend on your age:
Creatine: Very Different For Young & Old People
Most research on creatine’s effects on humans has usually been either collegiate athletes or seniors, which leaves quite a research gap in the middle—so it’s unclear at what age the muscle-building effects begin to taper off, and at what age the cognitive benefits begin to take off.
Want a quicker fix?
If you want to reduce your facial puffiness acutely (e.g., you have a date in an hour and would like to not have a puffy face), then there are two things you can do that will help immediately, and/but only have short-term effects, meaning you’d have to do them daily to enjoy the results every day:
The first is an ice bath; simply fill a large bowl with water and ice cubes, give it a couple of minutes to get down to temperature, hold your breath and plunge your face in for as long as you can comfortably hold your breath. Repeat a few times, and towel off.
This helps by waking up the vasculature in your face, helping it to reduce puffiness naturally.
The second is facial yoga or guā shā, which is the practice of physically manipulating the soft tissues of your face to put them where you want them, rather than where you don’t want them. This will work against water retention puffiness, as well as cortisol puffiness, lymphatic puffiness, and more:

Which Comes First, Cardio or Weights? – by Alex Hutchinson
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.
This is a book of questions and answers, myths and busts, and in short, all things exercise.
It’s laid out as many micro-chapters with questions as headers. The explanations are clear and easy to understand, with several citations (of studies and other academic papers) per question.
While it’s quite comprehensive (weighing in at a hefty 300+ pages), it’s not the kind of book where one could just look up any given piece of information that one wants.
Its strength, rather, lies in pre-emptively arming the reader with knowledge, and correcting many commonly-believed myths. It can be read cover-to-cover, or just dipped into per what interests you (the table of contents lists all questions, so it’s easy to flip through).
Bottom line: if you’ve found the world of exercise a little confusing and would like it demystifying, this book will result in a lot of “Oooooh” moments.
Click here to check out Which Comes First, Cardio or Weights?, and know your stuff!
PS: the short answer to the titular question is “mix it up and keep it varied”
