Every spring, Americans dutifully adjust their clocks forward to daylight saving time, and every fall, back to standard time — but no one seems very happy about it. The biannual time shift is not only inconvenient, it’s also known to be acutely bad for our health. The collective loss of an hour of sleep on the second Sunday in March has been linked to more heart attacks and fatal traffic accidents in the ensuing days. \n Now, a study by Stanford Medicine researchers finds there are longer-term hazards as well — and better alternatives. \n The researchers compared how three different time policies — permanent standard time, permanent daylight saving time and biannual shifting — could affect people’s circadian rhythms and, in turn, their health throughout the country. Circadian rhythm is the body’s innate, roughly 24-hour clock, which regulates many physiological processes. \n The team found that, from a circadian perspective, we’ve made the worst choice.…
