Anonymous users2024-02-10The 8-hour sleep theory, as a universal recommendation, does not apply to everyone. The sleep needs of each individual who raises their hands vary from person to person, so 8 hours cannot simply be used as the sole measure of healthy sleep. In fact, sleeping for too long can also have a negative impact on the body, leading to fatigue.
So, what kind of sleep is considered healthy?
Personalized sleep time: Everyone's sleep needs vary depending on age, lifestyle habits, physical condition, etc. In general, adults sleep between 7-9 hours per day, and older people may need less sleep.
The key is to adapt to your situation and make sure you don't over-fatigue or oversleep.
Sleep quality: Sleep quality is another important measure of healthy sleep. Good sleep quality is manifested as falling asleep easily, waking up less during sleep, and feeling more energetic after waking up.
Sleep regularity: Maintaining a regular sleep schedule and falling asleep and waking up at similar times each day can help establish a good biological clock. This helps to improve the quality of sleep and allows the body to adapt to a regular routine.
Comfortable sleeping environment: Maintaining a quiet, dark, and comfortable sleeping environment is conducive to improving sleep quality.
If you find that you still feel tired after sleeping for 8 hours, it is recommended to pay attention to factors such as your sleep quality, work and rest routine, and sleep environment to find out what may affect your sleep. If necessary, seek the help of a medical professional.
