When you want a long life, begin to improve the quality of sleep. A study proved that most people who reach the age of 100 years have a good sleep quality.

“The age and health condition are two things that are most influenced by the duration and quality of sleep,” said Danan Gu, Ph.D. from Portland State University who led the study, quoted from ScienceDaily.

Since 2005, Gu and his colleagues made observations of China’s 15 638 residents aged 65 years and over, in all 22 provinces. A total of 2794 in antarnya aged 100 years or more, while those aged 90-97 years as many as 3927 people.

Sleep quality in 65 percent of participants were categorized as good and very good, with an average duration of 7.5 hours a day including naps. Surprisingly, participants with the age of 100 years and over have the sleep quality better than 70 percent of 65-79 year-old.

Health issues are also closely related to the quality of sleep. Experience deep sleep on the participants who have health problems observed 46 percent lower. This happened to participants who are experiencing anxiety, chronic illness, and routine life unpleasant.

Another fact which is revealed, the relationship between the sexes with sleep quality. Experience deep sleep on male participants 23 percent more than in female participants.

This survey was not designed to actually see the cause-effect relationships. However, from existing data, the authors believe there is strong correlation between quality of sleep to health and longevity.

China deliberately chosen as the location of the study, because the elderly population in the region recorded the highest in the world. Based on World Bank data (World Bank), nearly 40.5 million of the total 1.3 billion population of China has the age of 75 years and over.

Observations since 2005 have been published in the journal Sleep. At the end of this year, the same team will also publish the years 2008-2009 as the comparison data.
