Q: Sometimes if I wake up early and it's too soon to start the day, I fall back asleep. But later, I wake up feeling tired. Would it be better if I just got up when I initially woke up?

First of all, you have to determine your own sleep requirement, which is how many hours of sleep you need to function during the day. The average is 7.5-8 hours, but some people can function adequately with 4 hours or less while some need 9 hours or more.

A person should stay in bed only for the entire duration of sleep requirement, no longer. At times, a person can experience sleep inertia, or a state of reduced alertness, performance, or vigilance when they wake up. This is often caused by staying in bed longer than necessary and can be worse when someone wakes up from deep sleep. Don't stay in bed longer than you are required.
