Sleeping Less Than 5 Hours Was Linked to Higher Risk of 37 Diseases

Sleeping less than five hours a night was associated with a higher risk of dozens of diseases in a large study that tracked nearly 100,000 adults for almost nine years. The analysis also found that people who slept less than seven hours a night had a higher risk of developing or dying from a wide range of conditions, including heart disease, stroke, diabetes, and certain cancers.
