Why Permanent Daylight-Saving Time Is Bad for Your Health, Sleep Scientists Say

Permanently moving to daylight-saving time is likely to cause more harm than good when it comes to our health, sleep science indicates.

For years, researchers have bemoaned the biannual changing of the clocks, saying shifting just one hour is linked to a slew of negative health effects, including an increased risk of heart attack and stroke. But when the U.S. Senate recently passed a bill to make daylight-saving time permanent, sleep experts became more alarmed.  

Legislators picked the wrong time, they say.
