Don't let the night light become poison to you
Everyone knows that a balanced diet, exercise and sleep are the three major elements for maintaining health, but the prerequisite for quality sleep is that the night must be dark enough! Because darkness is like the fourth key to deep sleep.
As long as you are in a dark environment, your body will begin to secrete melatonin, which will gradually lower your blood pressure, blood sugar, and body temperature, and naturally enter a sleep state. If you are still exposed to daylight at night, melatonin will be suppressed by more than half, and even stimulate the secretion of "cortisone". Cortisone is originally a hormone that makes people wake up during the day. It will speed up the heartbeat and raise blood pressure, making people more and more awake, but it will become a resistance to sleep.
Artificial light at night not only affects sleep, interferes with the body's circadian rhythm, but may even increase the risk of breast cancer. When the biological clock is disrupted and melatonin is reduced, cell repair ability will be reduced, which can easily lead to chronic inflammation and disease in the long run. In fact, in addition to helping to fall asleep, melatonin also has the functions of antioxidant, inhibiting tumors, delaying aging, and protecting the cardiovascular and metabolic systems. It is an indispensable night repair helper for the body.
Under normal circumstances, melatonin rises at night, reaches a peak in the middle of the night, and drops in the early morning; cortisone is secreted more during the day. If the indoor environment is too bright at night, if we use our mobile phones before going to bed and turn on the lights to sleep, our bodies will think it is still daytime. As a result, it will be difficult to fall asleep, not sleep deeply and not be full. Therefore, if you want to improve your sleep and gain health, the best thing to do is to dim the lights before going to bed and turn off the night light when you fall asleep to return to total darkness at night. This is more effective than taking health supplements!
