Wearing a watch at night is harmful to your health, especially wearing a luminous watch, because the luminous materials on the luminous watch are usually radium and zinc sulfide, which are harmful to your health. If you wear a luminous watch for a long time, your body will be affected by radium radiation for a long time.
Wearing a watch will also put pressure on the blood vessels of the wrist, especially those who like to sleep by the wrist, which has a greater impact on the body. This will lead to the serious pressure of the wristband on the blood vessels, resulting in poor blood flow after long-term pressure on the blood vessels.
If you wear a watch while sleeping, it is not conducive to the maintenance of the watch. Because the temperature in the bed is relatively high, water vapor may be generated in the watch mirror, and dander and dust falling on the bed are more likely to enter the watch mirror, which will affect the operation of the internal parts of the watch for a long time.
