Human Health
Timing of medical treatment in coordination with the body clock may significantly increase efficacy and reduce drug toxicity or adverse reactions. For example, appropriately timed treatment with angiotensin converting enzyme inhibitors (ACEi) may reduce nocturnal blood pressure and also benefit left ventricular (reverse) remodelling.
A number of studies have concluded that a short period of sleep during the day, a power-nap, does not have any measurable effect on normal circadian rhythms, but can decrease stress and improve productivity.
There are many health problems associated with disturbances of the human circadian rhythm, such as seasonal affective disorder (SAD), delayed sleep phase syndrome (DSPS) and other circadian rhythm disorders. Circadian rhythms also play a part in the reticular activating system, which is crucial for maintaining a state of consciousness. In addition, a reversal in the sleep–wake cycle may be a sign or complication of uremia, azotemia or acute renal failure.
Studies have also shown that light has a direct effect on human health because of the way it influences the circadian rhythms.

Famous quotes containing the words human and/or health:
“Sure the people are stupid: the human race is stupid. Sure Congress is an inefficient instrument of government. But the people are not stupid enough to abandon representative government for any other kind, including government by the guy who knows.”
—Bernard Devoto (1897–1955)
“All health and success does me good, however far off and withdrawn it may appear; all disease and failure helps to make me sad and does me evil, however much sympathy it may have with me or I with it.”
—Henry David Thoreau (1817–1862)
