Safety Precautions
Low-temperature burns are burns that occur when a heating element warmer than body temperature is applied for a long time, causing symptoms such as erythema and blisters. Note that low-temperature burns can sometimes occur without subjective symptoms.
Do not use outside of shoes.
Do not use with footwear that allows air to enter easily, such as slippers, sandals, or oversized shoes, as this may cause high temperatures.
Do not use while sleeping.
Do not use in conjunction with other heating appliances, as this may cause high temperatures.
Do not use on any part of the foot other than the underside of the toes.
Do not use when exercising, such as jogging.
Do not use if you have impaired sensation or blood circulation, such as due to diabetes.
Do not use if the person is an infant or physically disabled and unable to remove it themselves.
If you feel it is too hot, remove it immediately.
Avoid using in situations where you cannot immediately remove it if you feel it is too hot.
Do not use multiple warmers on one foot simultaneously.
Those with sensitive skin should be especially careful of low-temperature burns.
Do not apply directly to the skin.
In the unlikely event that symptoms of a burn appear, discontinue use immediately and consult a doctor.
