[|Human|] I am usually light-headed in the morning and during the day but it goes away in the early evening until the next morning. This will happen for a while and then it will go away for a few weeks. Any suggestions? I am not overweight and exercise daily.
[|AI|]  Hello and thank you for asking Chat Doctor, I understand your concern. You are probably experiencing low blood pressure when you stand up, called orthostatic hypotension. As a result, not enough blood reaches your brain, and you feel lightheaded or dizzy. Here are some advices: move gradually from lying down to sitting to a standing position, wiggle your toes and flex your feet before you stand up. This causes the muscles in your legs to squeeze more blood back up into your heart and to slightly raise blood pressure. Try to sleep with your head higher than your feet keeps blood pressure higher. Chat Doctor.  Unless you have high blood pressure already, this is a good idea.
