Abandoning daylight saving time could prevent over 300,000 stroke cases a year in the US, study claims

Switching to daylight saving time has long been associated with various acute medical conditions. A new study into its chronic impacts argues for scrapping it entirely.

Abandoning the biannual switch to daylight saving time could prevent more than 300,000 strokes and slash over 2 million obesity cases a year, a new model using data from over 300 million Americans suggests.

Adopting permanent standard time (ST) takes less toll on our circadian rhythm — the body's rough 24-hour pacemaker — than daylight saving time (DST) or flicking between the time policies twice a year, the researchers found.
