People usually spend 1/3 of the day and night sleeping, i.e., they go to sleep at night and wake up during the day, forming a sleep-wake rhythm. Sleep-wake rhythm disorders are sleep disorders caused by a sleep-wake rhythm that is different from the usual one. The disorder is usually seen in adults, but is rarely seen in childhood or adolescence. The dietary contraindications of sleep-wake time disorders: Avoid eating a full meal. Do not eat before going to bed, so as not to add to the gastrointestinal burden. Avoid drinking strong tea and coffee Do not drink strong tea, coffee and other foods at night, so as not to affect the normal sleep due to mental excitement or frequent urination. Avoid drinking alcohol Research has proven that drinking alcohol seems to help people fall asleep, but it is actually incorrect. Alcohol releases a natural stimulant in the metabolic process that disrupts our sleep in the second half of the night. Warm tip: Drinking alcohol before bedtime was once thought by many to promote sleep, but recent studies have proven that while it can make people fall asleep quickly, it keeps sleep conditions in the light sleep period and makes it difficult to enter the deep sleep period. So, even if people who drink alcohol sleep for a long time, they will still feel tired when they wake up.
