Why sleep is needed ? Your body will be able to rest when you sleep after doing various activities throughout the day. Not only the body but also your brain will rest then. If you sleep properly, you will be able to work with new vigor again the next day. A person needs 6/7/8 hours of sleep considering age , occupation or amount of work . But since you are saying that you are having trouble getting up in the morning even after 8/9 hours of sleep, it means that you are not actually getting any sleep. One thing to keep in mind is the name of closing the eyes from lying down but not sleeping. Sleep means rest. Your brain may not be resting. And this is why you feel uncomfortable when you wake up in the morning . Didn't say anything about whether you had various dreams in your sleep. Many people have nightmares while sleeping. If this is the case with you then I would say you need to see a doctor. And before going to bed at night, get rid of all worries and then go to sleep. Blood pressure is a problem but sleep is not good. So you first see where your main problem is. Then he has to take action accordingly. And if you don't understand something by yourself, then you must see a doctor. Because sleep is very important. If you can't sleep properly, your life will be ruined. Thanks.
