The Claim
Some believe that taking melatonin can permanently reset their circadian rhythms, providing a long-term solution to sleep disorders.
Origin
This idea might stem from the way melatonin is used to manage temporary circadian disruptions like jet lag.
What Science Says
Melatonin can temporarily shift circadian rhythms, as shown in circadian rhythm research and clinical trials, but it does not cause permanent changes. Adjustments in sleep patterns require continued use or lifestyle changes to maintain effects.
Verdict
Partially True
