Good quality sleep can add years to people’s lives, study suggests

Researchers say findings indicate quantity of sleep alone is not enough to benefit; quality is key

It is no mystery that a good night's sleep and a lie-in can improve your day. But researchers are suggesting that, far from just being enjoyable, quality sleep may even add years to people's lives.

Men who regularly sleep well could live almost five years longer than those who do not, while women could benefit by two years, research suggests. And they could also enjoy better health during their lives.
