why do I have hypetension when I'm awake but when I sleep it goes away when I wake up

There are several reasons why blood pressure may be higher during waking hours compared to when you are asleep. One possible explanation is that during the day, your body is more active and stress levels may be higher, which can contribute to an increase in blood pressure. Additionally, certain lifestyle factors such as diet, exercise, and caffeine consumption may also play a role in elevated blood pressure during waking hours.

When you sleep, your body goes into a state of relaxation and your blood pressure naturally decreases. This is known as nocturnal dipping, which is a normal process where blood pressure drops by about 10-20% during sleep. If your blood pressure does not decrease during sleep, it may be a sign of an underlying health condition such as sleep apnea or problems with the autonomic nervous system.

It is important to monitor your blood pressure regularly and consult with a healthcare provider if you have concerns about fluctuations in your blood pressure. They can provide further evaluation and recommend appropriate treatment to help manage and control your blood pressure levels.
