Lack of physical activity detrimentally increases several risk factors for chronic disease and death... Inactive people are more likely to develop obesity, diabetes, cardiovascular disease (heart disease and stroke), osteoporosis and some cancers (breast and bowel), all of which pose major public health problems.

For serious cases of rhythmic misalignment bright light therapy can also be used.
