When does the clock go back7/25/2023 How does changing the clock impact mental health? After the clocks change, the company noted a 10 to 15 per cent increase in accident volumes during that time compared to the rest of the day. Research has also shown an increase in car accidents when the cars go back in the colder months as drivers adapt to the time change.Īccording to data by Zurich Insurance, drivers are more likely to have an accident between 4pm and 7pm in November, as the evenings get darker earlier.

The sleep-deficient mice also had twice the level of certain white blood cells in their circulation, and lower amounts of hypocretin, a hormone that plays a key role in regulating sleep and wake states. It found that, after 16 weeks, mice who had their sleep cycles disrupted developed larger arterial plaques compared to the mice with normal sleep patterns. Disturbed sleep could also potentially lead to a higher risk of cardiovascular disease.Ī 2019 study by researchers at Harvard Medical School and the Massachusetts General Hospital examined the impact of sleep deficiency on heart disease in mice. Whether it is gaining an extra hour or losing an hour of sleep, this causes disruption to the sleep cycle and can be difficult for some people to adjust back to a normal schedule. So what is the impact of turning back the clocks on our health? How does changing the clock impact physical health?Īccording to the Mayo Clinic, the human brain has a biological clock, also known as a circadian rhythm, that runs on a 24-hour cycle. There are also some health concerns linked to the time change, as some studies have shown it disrupts the body’s natural sleep cycles, which can affect both physical and mental health.
