Blood pressure is affected by many factors related to sleep. This includes its duration, quality and regularity.
The possibility of developing hypertension may increase with both lack of sleep and excessive sleep. The optimal sleep time for adults is 7-9 hours per day. It is important to sleep regularly. A meta-analysis of 16 studies involving more than 1 million people found that sleeping less than 7 hours a day increased the risk of hypertension by 7%, while sleeping less than 5 hours a day increased the risk of hypertension by 11%.
Frequent tossing, turning, or waking up is closely associated with increased blood pressure and the risk of developing hypertension. Even if you sleep enough hours a day. In a study of adults, researchers found that those who rated their sleep quality as very poor had a 22% higher risk of developing hypertension. Participants with very poor sleep quality had an even higher risk, at 48%, compared to those who reported high sleep quality.
Those whose sleep patterns vary greatly are much more likely to suffer from hypertension than those who have regular sleep patterns. The consequences of this can make themselves felt quite quickly. A study of 1,600 older adults found that just one week of irregular sleep caused blood pressure to rise even in people without hypertension. Another 9-month study showed that an average 34-minute change in bedtime increased the risk of hypertension by up to 32%. And this does not depend on the total sleep time or the time of falling asleep.
If you have obstructive sleep apnea, you are at risk of developing high blood pressure. Up to 50% of this disease have hypertension and vice versa. Sleep apnea occurs especially in people with resistant hypertension, that is, when blood pressure remains high even while taking medications or other treatments.
