1. Disrupted sleep-wake cycles can result from a loss of normal circadian rhythm . 2. Also, circadian rhythm of autonomic nervous system activity was dampened during confinement. 3. The circadian rhythm influences the ideal timing of a restorative sleep episode. 4. Studies focused on bone, neuromuscular and vestibular physiology, circadian rhythms , and metabolism. 5. Circadian rhythm exerts some influence on the nighttime secretion of growth hormone.6. These observations indicate that body temperature is partially regulated by circadian rhythms . 7. Recommended treatments for circadian rhythm disorders are light therapy and dark therapy. 8. Inhibiting proteasome function leads to a circadian rhythm with a longer period. 9. Mice whose visual photoreceptors are destroyed by disease still have circadian rhythms . 10. Researchers continue to pursue a range of health topics connected to circadian rhythms .
