Although the change applies to most of the country, there are areas where it is not implemented, such as Hawaii, most of Arizona, and territories like Puerto Rico, Guam, and the Virgin Islands.
Experts advise anticipating change with gradual adjustments to sleep and meal schedules. Additionally, exposing oneself to sunlight in the morning, reducing screen time before bed, and avoiding stimulants like caffeine can help minimize the impact on the body.
