Some people sleep 5 hours and wake up feeling energetic and ready for a new day.
Some people sleep more than 8 hours and still feel lethargic, restless and tired.
This shows that it is not how many hours you sleep that matters. What is important is the quality of sleep. If your sleep is shallow, you can’t really get a good restful sleep. If yours is deep sleep, you are bound to feel great the next day.
But how to get a good night sleep? There are many ways that people would advise – drink milk before you sleep; don’t eat after 8 pm; don’t watch TV before you sleep; have a wash with warm water etc..
This really depends on individual. If your mind is stressed out, probably the above won’t help much.
