The dark side of daylight saving time

The start of daylight saving time in the spring can have a profound impact on people’s well-being. Moving the clock ahead one hour can cause sleep deprivation, affect focus and concentration, and exacerbate existing problems like depression, anxiety, and seasonal affective disorder. People can lessen the effect by taking steps a week prior to the time change, such as adjusting their sleep schedule, getting more light exposure, and cutting back on caffeine and alcohol.
