Take a nap for health, low blood pressure, and take a nap for no more than half an hour.
Actually, I don't know what you want to ask or give you such advice. I don't take a nap, but I can actually take a nap. It takes less than half an hour to take a nap. Half an hour's sleep can make you refreshed in the afternoon, but sleeping too much will make you feel more sleepy, and you will have no spirit in the afternoon.
