How many hours of sleep is the healthiest every day?

Traditionally, people think they need 8 hours' sleep every night to stay healthy. However, recent research shows that the sleep time required by each person varies from person to person, and the sleep time may be between 6 and 9 hours.

So everyone has no fixed sleep time. The amount of sleep a person needs depends on many factors, including age, health, lifestyle, work pressure and so on. In some cases, such as some diseases or pregnancy, people may need more sleep.

In addition, it is important to pay attention to the quality of sleep, not just the time of sleep. A person's sleep quality will be affected by many factors, such as environment, diet, exercise, stress and so on. A healthy sleep needs a certain depth and continuity, and it needs to be undisturbed. In order to get better sleep quality, you can try the following methods:

Create a quiet, comfortable, dark and cool sleeping environment.

Exercise regularly, but don't do strenuous exercise within 2 hours before going to bed.

Avoid drinking irritating substances such as caffeine, alcohol and nicotine before going to bed.

Avoid using mobile phones, computers, televisions and other electronic devices before going to bed.

Establish a regular sleep schedule and try to get up while sleeping.

In short, a healthy sleep mode should be based on personal needs and sleep quality. If you feel tired or lack of energy, you may need to change your sleep habits to improve your sleep quality and overall health.
