Many people think that just sleeping enough hours is enough, but experts say that sleeping at the wrong circadian rhythm also increases the risk of disease.
According to the National Sleep Organization (USA), frequent late sleep can disrupt the biological clock, reducing the quality of sleep even if sleep time is still sufficient. This prolonged condition easily leads to daytime fatigue, memory decline, reduced work performance and increased risk of stress.
Dr. Abhinav Singh, a sleep medicine expert at the National Sleep Foundation (USA), said that the human body is programmed to rest at night. When staying up late for a long time, the hormone melatonin is affected, causing deep sleep difficulty and reducing the body's ability to recover.
Meanwhile, the Stanford Medical System (USA) warns that prolonged late sleep is also associated with the risk of high blood pressure, metabolic disorders and cardiovascular disease. People who regularly stay up late also tend to eat more at night, thereby increasing the risk of obesity and type 2 diabetes.
Experts recommend that people who regularly sleep after 11 pm should build relaxation habits before bed such as reading books, listening to light music or taking a warm bath. At the same time, it is necessary to limit the use of phones and computers for at least 30 minutes before going to bed to avoid blue light that inhibits melatonin.
In addition, you should maintain a fixed sleep and wake-up time every day, including weekends. If insomnia, staying up late persists with fatigue or mental decline, people should see a doctor for early support.
