Most Americans will set their clocks back on Nov. 2 — but a new study led by Jamie Zeitzer, co-director of the Stanford Center for Sleep and Circadian Sciences, says those twice-a-year clock changes may be quietly damaging your health.
Your body runs on an internal 24-hour rhythm called your circadian clock. It controls sleep, hormones, metabolism, mood, and cellular repair. And here’s the kicker:It does not adapt well to artificial time changes.
Even a one-hour shift can throw off:
- Sleep timing
- Hormone release
- Appetite and metabolism
- Cognitive performance
- Stress levels and inflammation
Spring Forward Is the Most Dangerous
Research shows losing an hour in March leads to:
- More heart attacks
- More car crashes
- Higher hospitalization rates
- Increased insomnia and mood issues
It’s basically jet lag — without the vacation.
But “Fall Back” Isn’t Safe Either
Gaining an hour still disrupts your biology. Studies show the fall shift can cause:
- Fragmented sleep for up to a week
- Early-morning wakeups
- Irritability and fatigue
- Disrupted hunger hormones
- Circadian misalignment, especially in adults over 35
Your brain loves stability. Clock changes don’t give it that… SO my questions to you are:
Why does this matter? And should the clock changes end??
