Daylight Saving Time, or DST, is a practice where clocks are set forward by one hour in the spring to make better use of natural daylight during the summer months. However, this time change can have significant effects on people's mental and physical health, particularly in the short term. The one-hour change may not seem like much, but it can wreak havoc on people's sleep patterns, making them feel worn out, groggy, and less alert. According to a study by the University of Colorado Boulder, car accidents rose by 6% after the springtime change, highlighting the potential risks associated with DST.

Trouble sleeping can exacerbate conditions like anxiety, depression, and seasonal affective disorder, as the time change disrupts the body's natural 24-hour cycles that control vital functions like eating, mood, and sleep. Exposure to light plays a crucial role in regulating these cycles, and the darker mornings and lighter evenings created by the time change can throw off the body's internal clock. With less morning light, the body may produce lower amounts of the hormone serotonin, which elevates mood, while evenings with more light may delay the production of the hormone melatonin, which promotes sleep.

The transition from winter to spring can trigger mental health problems for many people, with about 10% of people with seasonal affective disorder experiencing symptoms during the spring and summer months. Sleep deprivation is also common in the first few days of the time change, with people sleeping 40 minutes less on Mondays after DST starts than they do on other nights of the year. To mitigate these effects, experts recommend improving sleep habits, enjoying sunny days, following a healthy diet, and keeping moving. Some natural alternatives to therapy and medication for milder cases of seasonal affective disorder and depression include:

Here are some tips to help adjust to the time change: * Improve your sleep habits by changing your sleep schedule over a few days in increments of 15 or 30 minutes to gradually adopt a new routine. * Enjoy sunny days by taking a brisk walk or sitting in a park to soak up the sunshine and help adjust your internal clock. * Follow a healthy diet by avoiding overindulgence in caffeine or alcohol, which can affect sleep habits. * Keep moving by exercising, even in small amounts, to help feel better and more energized. The clocks "spring forward" in the U.S. and Canada on March 9 and in the U.K. and Europe on March 30, 2025, marking the beginning of Daylight Saving Time. While the time change is designed to create more hours of sunlight, it can have significant effects on people's mental and physical health, particularly in the short term.

Daylight Saving Time is used in over 70 countries, according to timeanddate.com, and was initially introduced to conserve energy. However, the health risks associated with DST, including social jet lag, depression, and fatigue, are debated. Some states have passed legislation or resolutions for permanent DST, but approval from Congress is required. As the time change approaches, it is essential to be aware of the potential effects on mental health and sleep patterns and take steps to mitigate them. By understanding the impact of DST and taking proactive measures, individuals can reduce the risks associated with the time change and maintain their overall well-being.
