It’s not in your head. Those summer evenings around the fire, trips to the beach, and family hikes through the trail where you were practically covered in mosquito bites while everyone else was left virtually untouched? Why do mosquitoes bite some people and not others? It turns out, there’s actually a scientific reason some people are much more attractive meals to mosquitos than others. Luckily, there are also extra things you can do to help prevent those itchy bug bites in the future.
Why do mosquitoes bite some people more than others?
There are several factors that influence those winged insects’ choice of meal, and unfortunately, almost all of them are out of your control. Here’s what makes some people more attractive to mosquitos:
Mosquitos Love Heavy Breathers
Mosquitos are attracted by our breath- specifically, the carbon dioxide that we all exhale. So, if you’re outside working up a sweat (more on that later) and increasing your breathing rate, you’re putting yourself on more mosquitos’ radar. Unfortunately, this can also affect people who sometimes struggle with heavy breathing even when inactive- people with severe asthma, obesity that affects their mobility, and pregnant women.
Mosquitos Prefer Sticky People
Your sweat has a few different ingredients, the most attractive of which to mosquitos is lactic acid. The more you sweat, the tastier you’ll seem. In fact, there has been some evidence that older sweat leads to more mosquito bites than “fresh” sweat. That’s why you might notice you’re getting more bug bites the longer it’s been since you last showered (looking at you, family camping trip).
Mosquitos Are Obsessed With Drinkers
Bad news for everyone who likes to enjoy a glass of wine or a cold one on the porch at night. A 2002 study demonstrated that the increased ethanol content in your sweat and breath when drinking increases mosquito attraction.
Mosquitos Have Taste… In Bacteria
Our bodies are teeming with bacterial cultures- it’s all a part of keeping our bodies healthy and in balance. But everyone’s microflora collection is a little different, and some types of bacteria work to repel mosquitos, while others are practically ringing the dinner bell.
