Daylight savings time can be bad for your health. Losing sleep after the clocks move forward an hour could actually be more than just a mere annoyance. This time shift can raise the risk of health related issues. A study found that the stroke rate went up a lot higher right after daylight savings time.
- A 2016 study found that the overall rate for stroke was 8% higher in the two days after daylight saving time. Cancer victims were 25% more likely to have a stroke during that time, and people older than 65 were 20% more likely to have a stroke.
- “Stroke risk is highest in the morning hours,” Dr. Jori Ruuskanen, study author from the University of Turku, said in an email. “Previous studies have also shown that the disruption of the circadian clock due to other reasons (e.g. due to rotating shift work) and sleep fragmentation are associated with an increased risk of stroke
- The Monday and Tuesday after daylight saving time in the spring have also been associated with a 10% increase in heart attacks, according to a 2012 study at the University of Alabama Birmingham.
“For a paper on public health policy recommendations, Barnes cited studies that show how the annual removal of an hour has been linked to more workplace injuries, auto accidents and even hinders moral decision making.”
