The Xiaomi Smart Watch causes allergies symptoms.

The Xiaomi Smart Watch comes with a watch strap made of professional health antibacterial material that meets the medical criteria.
If you are allergic to the watch, please check the following aspects:
1. The watch is worn too tight with no room for your skin to breathe. A red, itchy rash may be caused by repeated friction after the watch leaves marks on the skin;
2. The watch is worn in the bath and left uncleaned for a long time, and the accumulation of residues leads to suspected allergies.
If there are only mild redness and itching symptoms, please refer to the following methods:
1. Please try adjusting the strap to your preferences during workouts. The watch should be tight enough if it does not slide up and down the wrist; 
2. For daily use, the strap can be slightly loosened to leave room for your skin to breathe. The watch should be snug but comfortable;
3. After wearing the watch for a long time, remove it and allow your wrist to rest for about half an hour. Wash and wipe the sweat on your arm and the strap after workouts. Clean and dry the strap before you wear the watch again.
Note:
If you experience severe allergies while wearing the watch, it is recommended to consult your physician before you put the watch back on.
