The magic behind heat it™
To relieve itch and pain, the affected skin area is briefly heated to approx. 124 °F. Current research suggests, heat application reduces the transmission of stimuli. Therefore, the itching signal can no longer be transmitted properly and the need to scratch disappears. In order to achieve this itch-relief effect on the skin nerves, a short heat pain is necessary.
heat it™ Scientific Study (June 23)Why mosquito bites itch?
Itching is the body's reaction to the mosquito saliva injected during the bite. Our immune system fights back by releasing histamine. As a result, the blood vessels dilate, the bite swells and begins to itch. Heat treatment of the bite causes various endogenous reactions that can relieve itching and pain.

Customer Reviews
I can’t recommend this device enough. It actually works as advertised and I don’t have to always have anti itch cream for my kids with me. I would recommend this to anyone!!
I work with mosquitoes on a daily basis in an entomology laboratory, so naturally I was intrigued by the Heat-it devices. After receiving this device, I was eager to test it out and see how well it worked, so I went to the mosquito cages*. I let mosquitoes bite my arms for 2 minutes, without disruption (much longer than most people would let a mosquito bite them for), and treated several bites with the Heat-it, while leaving other bites untreated.
Treated bites still had some swelling (which is to be expected), but to a lesser degree than untreated, but most significantly, they had much less of an itch. The itch of treated bites went away entirely within 10 minutes of use, whereas untreated bites were still noticeable even an hour later.
I quite enjoy how portable and easy it is to use. Highly recommend!
(*Disclaimer: I do not recommend sticking your arm in any mosquito/insect cages that you are unfamiliar with.)
Use this product on a recent camp out had a number of mosquito bites and in every case it stopped, the itch. Works as expected.
The very best small medical device that stops itching from bites on 1st application. And it is always with your keys. I would recommend this for everyone to buy, great product.
It really works so well! I'm back to buy more to make sure I have them everywhere!!!
