What does Harvard Medical School say?
Many of the costs of poor sleep go unnoticed. Medical conditions, such as obesity, diabetes, and cardiovascular disease, develop over long periods of time and result from a number of factors, such as genetics, poor nutrition, and lack of exercise. Insufficient sleep has also been linked to these and other health problems, and is considered an important risk factor. Although scientists have just begun to identify the connections between insufficient sleep and disease, most experts have concluded that getting enough high-quality sleep may be as important to health and well-being as nutrition and exercise.
