Complete Information on Advanced sleep phase syndrome with Treatment and Prevention
Advanced sleep phase syndrome is mediated with chronotherapy or bright light therapy.
Advanced sleep phase syndrome (ASPS) is a condition in which patients feel very sleepy early in the evening and wake up very early in the night. The disorder is more likely to appear in the elderly. ASPS may be corrected through exposure to bright light for two hours during the evening, which may shift the body’s circadian timing mechanism and delay the onset of sleep until a typical bedtime. The exact cause of ASPS is not known, but the disorder is related to circadian rhythms, which regulate the internal biological clock and influence functions such as sleep-wake patterns. It has been postulated that ASPS is a circadian rhythm disorder in which the phase of the circadian rhythm of sleep and wake is advanced in relation to the “normal timing,” which is synchronized, to the external environment.
