Earlier this year, the Senate passed a bill to make daylight saving time permanent. The idea of ending clock changes and sticking to one time was met with celebration — until scientists pointed out that such a change could cause a nationwide case of seasonal depression, learning loss and physical health problems.
Now the Sunshine Protection Act sits with the House. But as we prepare to change our clocks this November — and with news of Mexico mostly opting out of daylight saving time, effective this past weekend (the exceptions: towns and cities on the U.S. border) — the idea is sure to be debated again.
Popular opinion supports getting rid of clock changes, and for good reason — they’re disorienting and disruptive. But eternal daylight saving time is not the answer. Especially if we want to protect young people.
Humans evolved outside, in nature, and our brain clocks are exquisitely attuned to the sun. Standard time is an approximation of the solar day and is more or less in line with the rising and setting sun. Decades of research shows we’re at our best when we live harmoniously this way.
