In this solo video, dermatologist Shereene Idriss explains why female mosquitoes are drawn to certain people and how to stop the bites. She describes the biological cues that act as a mosquito GPS: exhaled carbon dioxide, heat, and a unique skin scent created by metabolites such as lactic acid, ammonia, and carboxylic acids that interact with skin bacteria. Factors that amplify these cues—exercise, pregnancy, and alcohol consumption—make some individuals especially attractive. Idriss clarifies that the itchy bump is not caused by the bite itself but by proteins in mosquito saliva that trigger a histamine‑mediated allergic reaction. She then offers three practical prevention strategies: (1) use a portable neck fan to create airflow over the face, neck, and chest; (2) after exercising, shower and stay indoors to remove sweat that signals mosquitoes; (3) wear light‑colored clothing at dusk and dawn to reduce visual contrast. For those already bitten, she recommends keeping mini de‑puffers and applying cortisone cream to reduce swelling and itch. The video blends scientific explanation with actionable tips for a bite‑free summer.

Why is it that every single summer I get eaten up alive by mosquitoes while my husband gets absolutely nothing? Because mosquitoes are literally attracted to your body chemistry. It's not your blood type, it's not because your blood is sweet. I'm sorry, fellas, if that's a pickup line that you're telling girls because your face looks effed up, but it's because your body is radiating a chemical fingerprint that female mosquitoes can detect from up to 1,000 feet away. Yes, female, because it's only the females that bite. Nature versus nurture. I'm gonna be sharing 3 ways to avoid getting bit, but before I So I genuinely think it is fascinating why and how this happens. So just bear with me. Your body emits carbon dioxide. So as you're breathing, that is like your GPS signal attracting that little mosquito in. And as that mosquito gets closer, it switches to, I think, your body's chemical je ne sais quoi signature scent. So your skin naturally releases compounds like lactic acid, ammonia, carboxylic acid, and other metabolites that through your sweat get on the surface of your skin and then interact with the billions of bacteria on the surface of your skin to create your own unique signature scent. Some people's scent profile is just more attractive than others, and that is why one person can get eaten alive, whereas somebody standing right next to them gets barely even a scraping. If you are exercising, if you're somebody who runs warm, if you're pregnant— sorry, Prego— or if you are drinking alcohol, you tend to produce more heat and carbon dioxide, and that makes you an easier target to find. But here's the part that most people will get wrong. Your itch is not from the bite itself, it is from the saliva of the mosquito. So when the mosquito puts their little zinger into your skin, they release certain protein that your body detects as a foreign body. And what happens? Histamine release. And with histamine release, you get dilated blood vessels, you get leakiness in your skin, swelling, and the itch nerves fire up, which is why you end up with that raised, swollen, incredibly itchy bump. So technically, you are allergic to the mosquitoes bit and not the bite itself. And so 3 ways to avoid being bit this summer is number 1, get a neck fan. Protect your face, neck, and chest, aka your moneymaker, and it's going to fluff those little mosquitoes away. Number 2, do not be the post-workout snack. Literally, when you work out, you have a neon open sign above your head for these mosquitoes. So after exercising, go shower, go indoors. And number 3, dark colors are attractive to mosquitoes because it creates more visual contrast. So at dusk and dawn, mosquitoes are more prevalent. Wearing lighter colored clothing can create less of a visual impact and make you a harder target to find. But if that mosquito already got its little stinger in you and you're just suffering through life, carry one of these baby— not that one, I have so many things in these pockets— mini de-puffers around to help to minimize the swell, and a cortisone cream can help to stop the itch. Hope this was helpful.
