4 minutes agoThe Health Risks of Permanent Daylight Saving Time
Permanent daylight saving time would keep clocks from changing twice each year, but it would also move one hour of morning daylight into the evening. Morning sunlight is among the most powerful biological signals we have for anchoring the body clock, while evening light does not provide the same biological benefit. That shift can disrupt circadian rhythms that regulate mood and sleep, undermining the very public health goal of reducing harm from clock changes.
