1, endangering health. Wearing a watch to sleep, especially wearing a luminous watch, will be harmful to your health. Because the hands on the luminous watch and the luminous materials on the dial are made of radium and zinc sulfide which are harmful to human body. Radiation from radium can excite zinc sulfide crystal to emit light. When people sleep with a luminous watch, they will be exposed to radium radiation for 8-9 hours during sleep, which is harmful to their health.

2. The watch is damaged. Sleeping with a watch is not conducive to the maintenance of the watch. When sleeping at night, people's dander and fiber stolen goods in bed are easy to go up the watchcase hill and gradually sneak into the watch. Over time, it seriously affects the parts and walking quality of the watch, especially when the wrist is exposed outside the bedding, the watch is easy to touch the bedstead, bedside table and wall, which may damage the case and even damage the parts.

3, causing unnecessary harm. Because watches and straps are angular, people often twist when they sleep. Therefore, wearing a watch to sleep is easy to snag or even damage knitted mosquito nets, underwear and bedding, causing unnecessary losses.

People's sleep is the most complete, systematic and effective rest method, and it is also an important content of scientific health preservation. But if we ignore some small things in sleep, it will have bad consequences for us, so remember to take off our watches before going to bed.
