Short-term use will not cause any harm, but long-term use will lead to erythema and blisters when the skin is exposed to fever above body temperature for a long time.

When using the foot warming patch, do not touch the skin directly to avoid scalding. The best way is to stick it on the outside of socks.

When using, you need to wear shoes of the right size. If the air permeability of shoes is poor, which leads to the temperature drop of the foot warmer, you can take off your shoes for a period of time to let the air circulate, so that the foot warmer can warm up.

At the same time, avoid using it in the same place for a long time, and pay attention to confirm the skin condition. If it's not normal, take it off immediately.
