While feeling tired during the day at times is fine, feeling this way on a daily basis is something that does need attention.

You can consult your doctor after you figure out what the problem is and a doctor’s consultation can help you get prescriptions for medication which will help you to feel active and energized all day.Apart from having a problem in your body, depression could also cause you to feel sleepy all day. People who are depressed do not to want to get out of the house and they prefer to stay indoors. When people who are depressed think about the bad things happening in their life all they feel like doing is sleep. This is why you need to check if you are depressed.
