Why do I still feel tired after 8 hours of sleep?

Is it better to get 3 hours of sleep or none?
Yes, most of the time, catching even just a few zzz’s is better than nothing. When you truly have less than an hour, power napping for 20 could be in your best interest.

Is it OK to stay up all night?
Summary. It is generally best to avoid staying up all night, as going without sleep can adversely affect how a person copes the next day and may cause health problems.

Does lack of sleep affect your mind?
Sleep deprivation makes us moody and irritable, and impairs brain functions such as memory and decision-making. It also negatively impacts the rest of the body – it impairs the functioning of the immune system, for example, making us more susceptible to infection.
Is 2 hours of sleep better than none?
Sleeping for a couple of hours or fewer isn’t ideal, but it can still provide your body with one sleep cycle. Ideally, it’s a good idea to aim for at least 90 minutes of sleep so that your body has time to go through a full cycle.
Should I just stay up if I can’t sleep?
