Sleep well every night and be healthy every day! Don't let poor sleep poison your life! Sleeping habits are closely related to people's health. Once people are in a state of sleep debt due to insufficient sleep and poor quality for a long time, the brain will not have enough time to maintain itself, which will eventually cause the brain to become overworked and cause physical illness. Blue light and melatonin deeply affect sleep! Modern people's lives are closely related to technology. Perhaps most people have the habit of "scrolling on their phones before going to bed".
