Lack Of Sleep Can Cause High Blood Pressure

lack of sleepEveryone needs adequate sleep, because lack of sleep can lead to many health problems, including high blood pressure, a new study suggests.

People who lack of sleep were easier to be depressed and felt irritable in the morning. But the consequences don’t necessarily end there. Over time, sleep deprivation can contribute to high blood pressure.

When sleeping, a person will have a phase of sleep brain waves known as slow-wave sleep. This sleep phase is considered restorative and has been shown to be important for memory and mental performance.

In the study, involving 784 participants found people who spent less than 4% of their sleep time in the slow-wave phase had 83 percent higher chance of developing high blood pressure (hypertension).

“These results indicate an important aspect of good quality sleep with the risk of high blood pressure, and older people tend to get less slow-wave sleep as they age,” said Eve Van Cauter, the director of the Sleep, Metabolism and Health Center at the University of Chicago.

In a previous analysis, the researcher has found that sleep disorders was related to high blood pressure. Sleep disorder like sleep apnea, a chronic disorder in which a person wakes up struggling for breath several times during the night, this condition is strongly associated with high blood pressure.

Dr. Susan Redline, one of the study authors and a professor of sleep medicine at Harvard Medical School, says that going to bed and waking up at the same time each day, avoiding alcohol and tobacco before bedtime, as well as good “sleep hygiene” can help people sleep longer and more deeply.

“But the most important thing to maximize slow-wave sleep is to ensure that there is not a sleep disorder like sleep apnea or periodic leg movement that is causing disruptions,” said Dr. Susan.
