New study shows that car accidents are more common the week after daylight saving time
Car accidents INCREASE the week immediately after daylight savings time begins as people struggle to lose an hour of sleep, a new study reveals
- Investigators tracked car accidents between 1996 and 2017
- They discovered that accidents increased by six percent the week after daylight saving time
- The increase remained constant even after daylight saving time moved in 2007
A team of researchers at the University of Colorado Boulder has found a steady increase in the number of traffic accidents that occur each year, during the week immediately following summer time.
They analyzed 732,835 accident records collected between 1996 and 2017 and found a six percent increase in traffic accidents every year during summer time week. (He filtered all of the Indiana and Arizona records because none of those states observe daylight saving time.)
The short-term increase was also recorded with the 2007 change from daylight saving time from the first Sunday in April to the second Sunday in March.
Researchers at the University of Colorado Boulder discovered that traffic accidents increase by six percent during the week after summer time
In total, there were 627 fatal traffic accidents between 1996 and 2017 attributed to daylight saving time.
“Our study provides additional and rigorous evidence that switching to summer time in spring leads to negative impacts on health and safety,” said Céline Vetter, an assistant professor of integrative physiology at the University of Colorado Boulder. CU Boulder today.
“These effects on fatal traffic accidents are real, and these deaths can be prevented.”
The team also warned that, in any case, their findings can actually report less than the number of accidents from the database from which they extracted, the US Fatality Analysis Report System. UU., Only tracks serious accidents.
The database excludes benders or less serious defense incidents in which no official report or insurance claim was made.
Scientists have long known that the change to daylight saving time brings with it a series of risks to public health.
The team analyzed serious accident data taken from the US Fatality Analysis Report System. UU. Between 1996 and 2017, and discovered that the seasonal increase was constant, even after 2007, when the start of daylight saving time moved from April to March
Other studies have shown that heart attacks, strokes, and workplace injuries become more frequent during weakness after switching to summer time.
The increases are usually attributed to fatigue caused by the sudden loss of one hour of sleep as people change their clocks forward.
The effects of this change are more acute with people who are already overloaded with work or lack of sleep.
“Our results support the theory that abolishing time changes completely would improve public health,” said Vetter.
‘But where do we go from here? Do we go to permanent standard time or permanent summer time? “
HOW CAN LIGHT SAVING AFFECT YOUR HEALTH?
There are more and more calls from scientists and experts to change daylight saving time to try to reduce their effects on people’s health.
Time changes get complicated sleep schedules, a potential problem when so many people are already lacking sleep, says Dr. Phyllis Zee, a sleep researcher at Northwestern Medicine in Chicago.
Research suggests that chronic sleep deprivation can increase levels of stress hormones that increase heart rate and blood pressure, and chemicals that trigger inflammation.
Scientists have also found that heart attacks They are more common in general in the morning, and incident rates increase slightly on Mondays after clocks are brought forward in the spring, when people usually get up an hour earlier than normal.
That increased risk associated with the change in time is mainly due to people who are already vulnerable due to an existing heart disease, said Barry Franklin, director of preventive cardiology and cardiac rehabilitation at Beaumont Health Hospital in Royal Oak, Michigan.
Studies suggest that these people return to their reference risk after the fall time change.
Numerous studies have also linked the beginning of summer time in the spring with a brief increase in car accidents, and with poor performance in the alert tests, both probably due to loss of sleep.
The research includes a German study published this year that found an increase in traffic accident deaths in the week after the start of daylight saving time, but there was no such increase in the fall.
Until Roenneberg, a specialist at Ludwig-Maximilian University in Munich, Dr. Zee from Northwestern said: “If we want to improve human health, we must not fight against our biological clock and, therefore, we must leave daylight saving time.” .
