A good night's sleep means getting eight hours of sleep

How much sleep do you get every night? Six hours? Eight hours? Some wake up groggy from a night of dreaming. Others sleep four or five hours but feel refreshed.

The normal structural sleep cycle is divided into two phases: non-rapid eye movement sleep (NREM) and rapid eye movement sleep (REM). NREM alternates with REM, which is called a sleep cycle.

What really determines the quality of our sleep is not the amount of sleep we get, but how many full cycles we sleep in a night and when we wake up. To be fully rested through sleep, we need to sleep for four to five complete cycles each night.

Snoring = better sleep

If you have a dad or boyfriend who snores, don't let them tell you that snoring means you sleep well.

Long-term, severe snoring is called sleep apnea syndrome, which can cause sleepiness, difficulty recovering sleep, fatigue or insomnia, and even sudden death, and is associated with a range of diseases such as hyperlipidemia and diabetes.

If you know someone who snores, remind them to keep a healthy schedule, exercise, stay awake during the day and not stay up late. If the snoring is very serious, be sure to seek medical attention immediately

I don't sleep enough on weekends

With the fast pace of modern society and great work pressure, many office workers have to stay up late and work overtime on weekdays. As a result, most of the weekend was spent catching up on sleep

Proper catch-up sleep can really help restore energy. However, long-term "catch up sleep" on weekends will break the weekday sleep rhythm and disrupt the body's original biological clock, which will cause metabolism disorders in the long term, and in serious cases will lead to chronic insomnia. It's okay to catch up on the occasional weekend sleep, but it's best not to make a habit of it.
