While most of the world follows standard time all year, much of the United States shifts between standard and daylight saving time (DST). Whether you enjoy falling back or springing forward, have you ever wondered about the health impacts of DST? Us too!
Besides disrupted sleep patterns, studies show that DST has also been linked to an increased risk of developing certain disorders, from cognitive and mental health issues to digestive and heart diseases. During the week after the shift to DST, research (Northwestern Medicine, Feb. 2021, nm.org) shows an associated rise in the following:
- Cardiovascular disease, with a 24% greater risk of heart attacks
- Injuries, including a 6% jump in fatal car accidents
- Stroke rate, which increases by 8%
- Mental health and cognitive issues, with an 11% increase in depressive episodes
- Digestive and immune-related diseases, with an increase of 3% in females over age 60
Until the US settles on a final time strategy, here are a few things you can do to keep yourself healthy during the DST window:
- Keep a sound sleep routine. Get 7-9 hours each night.
- Spend time outside in the AM. More natural light helps to preserve your circadian rhythm.
- Remove sleep disturbances. Avoid alcohol, caffeine & blue light at least 2 hours before bedtime.
- Exercise in the AM. Physical activity elevates your body temp which increases wakefulness, helping to reset your internal clock.
