chronotherapy
Pronunciation: KROH-noh-therapy
Treatment approach that uses controlled manipulation of sleep-wake timing to treat circadian rhythm disorders.
Full Definition
Chronotherapy is a therapeutic approach that involves the systematic manipulation of sleep-wake timing to realign disrupted circadian rhythms with desired schedules. Common techniques include bright light therapy, melatonin administration, and gradual sleep schedule shifts. The treatment is based on the principle that circadian rhythms can be reset through precisely timed exposure to external cues (zeitgebers). Chronotherapy is particularly effective for treating delayed sleep phase syndrome, advanced sleep phase syndrome, and circadian rhythm disruptions associated with shift work or jet lag.
Usage
Usage note: Distinguish from phototherapy, which may be used in other medical contexts; chronotherapy specifically targets circadian timing.
