Daylight saving time (DST) begins each year in March, requiring most regions in the United States to set their clocks forward by one hour. This change creates darker mornings but longer daylight in the evening. Originally introduced to save energy and make better use of daylight, DST affects people’s internal body clocks, which control sleep patterns. Studies show that sleep problems caused by DST can last for weeks. Research also links this shift to a short-term rise in heart attacks, strokes, and traffic accidents, highlighting its possible health risks. While most of the U.S. follows DST, states like Hawaii and most of Arizona stay on standard time all year. Other countries also use DST, though their start and end dates vary.

To adjust smoothly to daylight saving time, sleep experts suggest gradually changing sleep schedules. Going to bed 15 to 20 minutes earlier each night before the shift can help. Getting morning sunlight also helps reset the body’s internal clock, improving sleep and overall health. Lack of sleep has been linked to heart disease, obesity, and memory problems, making good rest essential. Lawmakers continue to debate whether to keep switching times or choose a permanent schedule. Health experts argue that standard time is better for natural sleep patterns. Until a final decision is made, individuals must take steps to reduce the impact of these changes.
