Too much sleep ‘bad for your heart’
GETTING too much sleep may be bad for your heart, a new study has found.
Research, published in the European Heart Journal, concluded that the amount of time a person sleeps is linked to their risk of cardiovascular disease and premature death.
It found sleeping too much – more than six to eight hours a day – raises the risk of serious health problems and fatality.
The study examined data on 116,000 people aged between 35 and 70 from 21 different countries. It analysed participants and returned to them about eight years later.
Researchers recorded 4,381 deaths and 4,365 ‘major cardiovascular events’.
They found people who slept longer than eight hours had a higher risk of dying or developing diseases of the heart or blood vessels in the brain compared to those who slept for between six and eight hours. “Sleep is essential to human health, and people spend about a third of their hours sleeping. It is increasingly regarded as an important lifestyle behaviour that can affect cardiovascular disease (CVD) and death,” the team of international researchers wrote. Compared to people who slept six to eight hours, those who slept a total of eight to nine hours a day had a five per cent increased risk.
