A good night's sleep can fend off the risk of heart disease, researchers said. It's especially true among older people. Blood pressure tends to go up at night in people over age 70.

Scientist studied the sleep patterns of more than 12-hundred senior citizens.

After four years, they found that most of those who had heart attacks or strokes were those who suffered from a lack of sleep.

In general, people are sleeping less these days in modern societies.

Sleep deprivation can also lead to obesity and diabetes.

Sleeping less than seven and half hours a day is considered a sleep deficiency.

The study was conducted in Japan.
