The heat added to the skin is distributed through blood flow. Pressure on the site where HEAT CHARGER® is used inhibits the blood flow while raising the temperature causing a burn.
The following is important:
1) Do not put pressure on the site where a HEAT CHARGER® is placed,
2) Do not put a HEAT CHARGER® in the same place for a long time, and
3) Move a HEAT CHARGER® immediately when feeling hot.
Pay careful attention especially when a HEAT CHARGER® is used for children, the elderly, people with vascular deficiency, people with disabilities or those who cannot remove HEAT CHARGER® immediately when they feel hot.
