Older people who get five hours of sleep a night or less may face a far greater risk of developing two or more chronic illnesses, such as heart disease, cancer or diabetes, compared to people who sleep longer, a new study suggests.

The research, published Tuesday in the journal PLOS Medicine, tracked the impact of sleep duration on the health of more than 7,000 men and women at the ages of 50, 60 and 70.

This was done via a 25-year follow up of participants in the Whitehall II cohort study involving members of the British civil service.

The British and French researchers, led by University College London, found that sleeping for five hours or less at the ages of 50, 60, and 70 was linked to a 30% to 40% increased risk of developing multiple chronic diseases versus people who slept for up to seven hours.
