A person's blood pressure changes all the time, and it's important to know when it reaches a high point, Rosenthal continues. Studies show that blood pressure normally falls at the beginning of sleep and begins to rise at around 4 a.m. Therefore, doctors advise hypertension patients to take their medication immediately upon rising. Patients who have secondary hypertension due to diabetes or an adrenal gland tumor have high blood pressure through the night. Blood pressure varies according to one's daytime activities as well, including working at a computer, driving, speaking on the phone, or even chewing food or gum.
Noise increases it as well.
