Circadian Rhythm Disorder

Circadian Rhythm Disorder refers to a group of conditions in which a person's internal biological clock, which regulates the timing of sleep and wakefulness, becomes misaligned with the external day-night cycle or with the demands of their social and work schedule. This misalignment can cause significant difficulty falling asleep, staying asleep, or waking at conventional times, even though total sleep quality may otherwise be normal when the person sleeps according to their internal rhythm. Common forms include delayed sleep phase, where sleep and wake times are pushed later, and disruptions caused by shift work or jet lag. The condition can significantly impact daytime functioning, mood, and overall health.

The most common symptoms include: Difficulty falling asleep or waking at socially conventional times; excessive daytime sleepiness; difficulty concentrating; mood disturbances. Early recognition is key to prompt diagnosis and effective treatment.

No, Circadian Rhythm Disorder is not contagious. It cannot spread through casual contact. However, certain risk factors and genetic predispositions may increase susceptibility.

Treatment options include: Treatment typically involves carefully timed light exposure therapy to help realign the internal clock; along with strict adherence to a consistent sleep-wake schedule. Melatonin supplementation at specific times can help shift sleep timing; and gradual schedule adjustments are often recommended for those dealing with shift work or jet lag.. Treatment should always be guided by a qualified Sleep Medicine specialist. Do not self-medicate.

While Circadian Rhythm Disorder cannot always be fully prevented, several measures can reduce risk: Maintaining a consistent sleep and wake schedule even on weekends; getting adequate morning light exposure; limiting light exposure in the evening especially from screens.

Consult a Sleep Medicine specialist if symptoms persist for more than a few days, worsen despite home care, or significantly affect your daily activities. Early diagnosis leads to better outcomes.
