Daylight Saving Time (DST) is more than just adjusting your clocks; it can profoundly impact your health in ways you might not anticipate. As we spring forward or fall back, our bodies must adapt to the change, leading to various effects. Here are eight unexpected ways DST can affect your health.
Disruption of Sleep Patterns

The immediate effect of DST is the disruption of our circadian rhythms, making it harder to fall asleep and wake up at our usual times. This disruption can lead to sleep deprivation, affecting mood, concentration, and overall health.
Increased Risk of Heart Attack

Studies have shown a slight increase in heart attack rates in the days following the start of DST. Losing one hour of sleep is thought to stress the heart, especially in at-risk people.
Impact on Mental Health

The change in time can affect mental health, leading to issues such as seasonal affective disorder (SAD), especially during the fall transition. The decrease in sunlight can affect serotonin levels, influencing mood and happiness.

Even minor sleep disruptions can impair the immune system's efficiency, making the body more susceptible to infections and illnesses. The week following DST, we can see an uptick in sickness attributed to this phenomenon.
Increased Accident Rates

The lack of sleep and the adjustment to new light conditions can lead to a higher rate of car accidents and workplace injuries. People are less alert, and reaction times can be slower.
Effects on Appetite and Metabolism

DST can mess with the hormones regulating hunger, leading to increased appetite and weight gain. The disruption of circadian rhythms can also affect metabolism, making it harder to lose weight.
Worsening of Chronic Conditions

For individuals with chronic conditions, such as diabetes or heart disease, the change in routine and sleep pattern can complicate the management and control of their condition, potentially leading to adverse health events.
Alteration of Exercise Routines

The change in daylight hours can disrupt regular exercise routines, either by providing more daylight hours in the evening to encourage activity in the spring or by reducing it in the fall, leading to decreased motivation for physical activity.
