Problems with the Body’s Internal Clock

Circadian rhythm sleep disorders lead to insomnia and excessive daytime sleepiness, impacting quality of life.

• These disorders arise from a misalignment between the internal circadian timing system and the external environment.
• Factors influencing circadian rhythm sleep disorders include physiological, behavioral, and environmental elements.
• Current treatments aim to align circadian rhythms or enhance the circadian signal using methods like bright light exposure and melatonin.
• The effectiveness of existing treatments is limited by the lack of adequate diagnostic tools and large-scale clinical trials.
• Advances in understanding the biological basis of circadian regulation may enable more targeted treatments in the future.
