Some studies show that lack of sleep can lead to increased blood pressure.
In October 2007 the American journal "Hypertension" published a study that said that women who sleep duration of less than 7:00 at night, there is an increased risk of developing hypertension. The study involved 10,300 women aged 35-55 years in 5 years. Compared with women who sleep which lasted 7:00, women, sleep, which lasted for 6 hours the risk of hypertension was 42% higher. Women who slept in the day not more than 5 hours, this risk was higher by 31%.
The same conclusion was reached by scientists as a result of a similar study in 2006, which indicates a lack of sleep effects on the risk of hypertension.
The researchers analyzed data on 4810 people aged 32-86 years. Among the study participants aged 32-59 years, those who slept less than a day 6:00 a risk of hypertension was higher than in 2 times. Participants older than 59 years, this relationship was not as pronounced.
