Staying constantly in the summer time would be bad for your health

According to a neurobiologist, staying in summer time all year round could disrupt our biological rhythm and promote certain health problems.

France goes to summer time in a few days, and this could be one of the last times. The European Commission has decided to end the change of time in 2021. Each member state must choose the time it prefers, in France, the results fell on March 3: the population wants to stay on time. 'summer. For our health, however, we should focus on winter time, according to a neurobiologist interviewed on the site of our colleagues 20 minutes.

More infarction and accidents

Since 1998, the European Union has been changing times twice a year to save energy. If the change of time is today in the breach, it is because it has not significantly reduced energy consumption, and instead causes health disorders. A study presented by the American College of Cardiology in 2016 showed a 25% increase in the risk of heart attack on the first Monday after the time change. The number of road accidents would also increase, because of the decrease in brightness.

Winter time: closer to our natural rhythms

Deleting the time change could be a solution ... If we adopt the right time! Questioned by 20 minutesThe neurobiologist Claure Gonfrier, vice-president of the Société Française de Chronobiologie, explains that staying in summer time would have adverse health effects. "The ideal time, from a chronobiological point of view, is solar time," says the researcher, "which is not already the time we live, since we live at GMT + 1 GMT corresponding to the Greenwich Mean Time and even GMT + 2 in summer, two hours later than solar time This schedule creates a two-hour social jet lag: our biological hours and activity schedules are shifted ". Staying in summer time means that the sun will set in later, but sunlight keeps us awake. Ultimately, this may disrupt our circadian cycles, the alternation between waking and sleep phase.

Disrupted sleep harms health

"It has been observed for many years that the populations located furthest west in their time zone, and which are the most offset from solar time, have the most metabolic disorders, sleep disorders, disorders of mental health, cancers and disorders of biological rhythms in general ", emphasizes Professor Claude Gonfrier. Teenagers and night owls / late risers would be the most exposed to these problems. For the early bird, the risk of seasonal depression hovers: staying in the summer time, the sun will rise to 10 hours during the winter. In the meantime, on March 31st, we'll have to move the clock another hour!
