Lack of Sleep Making Hypertension

Those who slept only 6 hours, 42 percent tend to have hypertension, while the habitual sleep no more than 5 hours the risk 31 percent higher. The research is reported in the journal Hypertension.

This research is the new women only, not on men. According to the head of the research, Dr. Francesco P. Cappuccio from Warwick Medical School, Coventry, these findings indicate the possibility of a special relationship of sex, decrease in sleep time, and blood pressure. However, the reason for certain of these findings is not yet known.

A number of studies that associate poor sleep quality to increase the risk of high blood pressure, diabetes, and heart disease. Much of the research is focused on people with sleep apnea respiratory disturbances (stopping the breath during sleep). However, some evidence indicates, the loss of sleep, without the interference of clear, also hurt health.

To research, Cappuccio and his team use data from long-term health study of 10,300 British civil officers aged white 35-55 years old. The researchers focused on respondents who are free from high blood pressure in the years 1997-1999 research phase and re-assessed in 2003-2005.

During phase two, the 76 and 68 percent, in a row, the group's origin, included in the evaluation. In the re-assessment, 20 percent of respondents diagnosed with high blood pressure and the risk is greater among women with a shorter sleep time.

Risk factors for heart disease, such as smoking, excess body weight, or lifestyle sedentari, contributing to the partial relationship. However, the relationship between sleep and free blood pressure still exists.

Experts speculate that the loss of sleep can contribute to high blood pressure. This time because of lack of sleep make nervous system is on the hiperaktif, which then affect the entire body system, including the heart and blood vessel.

According to the team Cappuccio, need more research to mengonfirmasi that affect sleep duration of level of blood pressure, and why this effect can be different in women and men
