Getting too little sleep can harm your health by making it harder for you to maintain a healthy lifestyle, according to a Finnish study in the International Journal of Epidemiology.
Research has strongly linked chronic poor sleep to everything from hypertension, diabetes, and heart disease to cognitive impairment and depression. One way that insufficient or disturbed sleep can contribute to these disorders, the new study suggests, is by increasing the likelihood that people will smoke, drink alcohol to excess, be physically inactive, and become overweight or obese (the result of consuming too many calories).
The researchers analyzed data from more than 37,500 Finnish government employees participating in a long-running study of lifestyle behaviors and health.
