Feeling itchy? There are some interesting new solutions to address that irritation.
There’s a compact device that connects to your smartphone, bypassing the usual creams and chemicals, using heat to alleviate insect bites instead.
We talked to Dr. David Bank, a certified dermatologist, to explore other clever methods for managing those nagging itches this summer.
So, why do bug bites itch anyway?
When an insect bites, it injects saliva into your skin.
“The protein in that saliva triggers an inflammatory response in your body, leading to the release of a chemical called histamine,” Bank noted.
“It’s this histamine that causes the redness, itching, and swelling associated with bites,” he added.
Enter: Heat
Developed by researchers in Germany, the device called Heat it launched in Europe in 2020 and made its way to the U.S. market in 2023.
About the size of a Bumblebee, it connects to your smartphone and generates targeted heat using its battery.
When applied to bug bites, it delivers a quick burst of warmth that can help relieve itching and pain from mosquito, horsefly, and bee stings.
The accompanying app allows users to adjust the temperature and duration based on their skin sensitivity.
Does heat really help with bug bites?
“Applying heat can break down the proteins in insect saliva,” Bank explained. “This reduces the release of histamine, leading to less redness, itching, and swelling.”
He also mentioned that heat can influence the nerve endings in the skin, effectively lowering the itch signals sent to the brain.
In a recent study involving over 1,750 participants, it was found that itching was reduced by 63% within just two minutes of device use, and after ten minutes, that figure increased to 78%.
Old methods vs. New technology
While this smartphone-powered solution is quite novel, the concept of using heat to relieve bug bites isn’t new at all.
For ages, people have turned to home remedies like warm compresses or heated metal spoons to ease discomfort.
“The issue with these traditional methods is that they often lack accuracy in temperature,” Bank pointed out. “If they’re not warm enough, they won’t work, and if they’re too hot, they can burn the skin.”
He mentioned that the ideal temperature range for treating bug bites is between 122°F and 125°F. The Heat it device maintains a steady 124°F, complete with adjustable settings for both children and adults with sensitive skin.
Additional tips
First and foremost, try not to scratch those bites — it usually makes the situation worse.
For mild cases, over-the-counter options like hydrocortisone or calamine lotion can be effective. Bank also suggests taking oral antihistamines such as cetirizine or loratadine to help reduce itching and other symptoms.
If the bite is painful, you might consider using pain relievers like acetaminophen or ibuprofen.
And if you notice any changes, like signs of infection or a severe allergic reaction, it’s important to seek medical attention right away.
