Frequently asked questions
When do I use heat it®?
heat it® can be used for all kinds of insect bites and stings, including those from mosquitoes, horseflies, bees and wasps. Whether you use heat it® straight away or later on, it can help relieve the symptoms effectively. When used immediately, symptoms can often be prevented altogether.
How hot does heat it® get?
heat it® classic & pro: Depending on the app settings, the treatment temperature can be set between 47°C and 52°C. You can choose a treatment duration of 4, 7 or 9 seconds (short, medium or long). Combined, these settings offer a total of 12 intensity levels.
heat it® unplug: Using the five-level dial, the treatment temperature can be set between 47°C and 51°C, with treatment times ranging from 4 to 8 seconds.
Is the treatment painful?
Whether the treatment feels painful or uncomfortable varies from person to person. As the skin’s sensitivity to heat differs between individuals and across different areas of the body, heat it® offers a range of treatment settings. For safe and effective use, please note the following:
Only a mild heat sensation is needed for an effective treatment. If you experience severe pain, stop the treatment. When using heat it® for the first time, select the lowest setting. The same applies when treating an area of the body you have not used it on before. Please refer to the instructions for use for detailed information.
What should I pay attention to?
heat it® may be used on children from the age of 3. From the age of 12, children may use heat it® themselves.
heat it® is designed exclusively for use on external skin. The device must not be used inside body openings, on mucous membranes, gums, nail beds, eyes, the outer ear canal or broken skin.
Before treating a bee sting, the stinger must first be removed. heat it® is not suitable for treating allergic reactions or tick bites.
Please follow the instructions for use. Improper use may cause minor burns.
How much battery does heat it® use?
heat it® classic & pro: With a fully charged smartphone, up to 1,000 treatments are possible at the highest setting. A sophisticated safety system helps protect both your smartphone and its battery.
heat it® unplug: This model has a built-in rechargeable battery that can be charged using a standard USB-C cable. A full charge provides up to 1,000 treatments.
How does the principle work?
The principle of hyperthermia for the treatment of itching and pain is based on a brief heating of the skin to which the nerves respond. Current research suggests that this reduces the transmission of the stimulus. As a result, the itch signal can no longer be properly transmitted and the need to scratch disappears. To achieve this itch-relieving effect on the skin nerves, a short period of heat pain is necessary.
In June 2023, we published our first study on the principle (abstract).
"New study proves effective and safe relief of itching and pain after insect bites by heat-based sting healers"
What happens when a mosquito bites?
The itching caused by a mosquito bite is a body reaction to the mosquito's saliva, which is injected during the biting process. Our immune system defends itself against the foreign saliva by releasing histamine. As a result, the blood vessels dilate, the bite swells and begins to itch. By heating the affected skin area with heat it®, various endogenous reactions are induced that can relieve itching and pain.
