IPA: /ˌkrɒnəʊθəˈrɛrəpi/
KK: /krɒnəʊθəˈræpi/
A method of treating sleep disorders by adjusting the times a person sleeps and wakes, aiming to realign their internal biological clock.
Chronotherapy can help people with insomnia by shifting their sleep schedule to better match their natural rhythms.
Chronotherapy is formed from "chrono-" (from Greek "chronos", meaning time) and "therapy" (from Greek "therapeia", meaning treatment or healing). The word refers to treatment that is timed according to the body's natural rhythms.
Think of 'time' ('chrono-') being used for 'treatment' ('therapeia') — that's why chronotherapy means treatment that considers the timing of the body's natural cycles.
