1. Turn your bedroom into a sleep paradise. First of all, your bedroom must be quiet, dark and dark, because the dark environment will promote the pineal gland to produce melatonin, which controls the circadian rhythm. Use heavy curtains or other things to isolate external light sources, and use fans to create a cool temperature, which is helpful for sleep. If the indoor air is too dry, you can also use a humidifier.

2. Increase the content of negative air ions in the air. Air negative ions can reduce the level of 5-HT(5- hydroxytryptamine) in brain and tissue by promoting the oxidative deamination of monoamine oxidase MAO, which causes obvious physiological changes in endocrine and nervous system, and has a good regulatory effect on autonomic higher center and autonomic nervous system. Therefore, it can improve the function of cerebral cortex, cheer up the spirit, eliminate fatigue, improve work efficiency, improve sleep and increase appetite. Small particle size negative ions, also called light ions or small ions, are equivalent to air negative ions in nature, and some materials are also called ecological negative ions. Medical research shows that it is air negative ions with small particle size that have medical and health care effects on human body. Because only negative ions with small particle size can easily penetrate the blood-brain barrier of human body and exert their biological effects.

Make sure your bed is only used for sleeping. Avoid working in bed, paying bills, reading or watching TV. If you want to only associate sleeping with your bed, all you need to do in bed is fall asleep instead of turning pancakes all night.
