sleep 5 “no” until dawn
1. Don’t leave your mobile phone on when you sleep.
At present, the research on electromagnetic waves is half good and half bad. Long term exposure to electromagnetic waves will affect the nervous system and physiological functions (decreased secretion of melatonin) and affect sleep.
2. You should not wear a watch when sleeping.
Not only watches, but also clothes that are bound or too tight during sleep should be avoided. Electronic watches have trace electromagnetic waves. Quartz watches or luminous watches contain radium radiation. Long term accumulation may affect nerves and brain waves, resulting in difficulty in falling asleep.
3. Don’t wear a bra when sleeping.
Influence on chest health: research indicates that those who wear bras for more than 12 hours a day have a 20 times higher risk of breast cancer than those who wear bras for a short time or do not wear underwear. The reason is that the chest tissue is compressed, which hinders the flow of lymph and makes the toxin stay in the chest.
4. Don’t turn on the light when sleeping.
Turning on the light to sleep will inhibit the secretion of melatonin and reduce the immune function of the human body. The secretion of melatonin is mainly affected by light. In places with strong light, melatonin is secreted very little, which is not conducive to sleep. Therefore, flight attendants, doctors, nurses and other night shift people have more than twice the probability of cancer than normal people.
5. Don’t wear makeup when sleeping.
The more often you sleep with makeup, the more serious your skin problems will be. Like other organs of the body, our skin also has a day and night rule. Removing makeup is not only a cleaning step, but also an important part of skin care, because night is the prime time for skin metabolism and self-healing. Don’t be bothered and ignore your delicate skin.
