According to a new study, a person needs at least 8 hours sleep in a day to keep himself healthy & to avoid all health problems specially related to the heart.

The study led by researchers in Sweden found that the risk of a heart attack dropped during the first week after the clocks were set back and people have an extra hour of sleeping.
 
The research, based on heart attacks in Sweden, shows that sleep deprivation has adverse effects on one’s cardiovascular health.

The study researchers found 5% increase in heart attack rate during Mondays to Wednesdays. Because the stress rate is higher during the week starts.

These days, the shifts jobs are going on so the people have to work in different shifts.

Working people are more affected from heart attacks than retired people because they don’t have flexible time to rest. The effect was more pronounced in women and in people under age 65.

Researchers suggest those who are working for more than 40 hours in a week, should get at least 2 days rest in a months and enough sleep.
