The best way to handle daylight saving time is to not wait for it. Scientists and product experts agree: shifting sleep, light exposure, and meal times gradually over several days before the clocks change makes the transition far easier than absorbing a full hour loss in a single night.
Emily Manoogian, a scientist at the Salk Institute, puts it plainly. “Our bodies can’t shift a full hour in one day,” she says. “So if you can break it up over two to three days, it makes it a lot easier. This looks like shifting your food, light, and sleep times by a 20 to 30 minute advance for a couple of days before the DST shift.”
Why Gradual Adjustment Matters
Manoogian points to both light and food as primary signals that synchronize the body clock. Animal studies suggest that adjusting breakfast and dinner times in sync with an upcoming time change can help the body return to its normal rhythm faster. Small daily shifts of 15 to 20 minutes on the alarm are far less disruptive than a sudden one-hour jump.
The health consequences of ignoring this are worth taking seriously. Manoogian says acute circadian disruptions like the daylight saving shift can contribute to insulin resistance, gut issues, anxiety, depression, and increased risky behaviors. A little planning is easier than a week of dysfunction.
Light as a Reset Tool
Morning light is one of the most direct ways to signal a schedule shift to the brain. Both Hatch and Lumie, two manufacturers of sunrise alarm clocks, recommend using light strategically during the days leading up to the change. “Light is one of the most powerful signals for resetting your internal clock, which is why morning light exposure is especially helpful after the daylight saving transition,” a Hatch representative says.
The two brands take different approaches to the same problem. Hatch’s Restore 3, priced at $170, connects to Wi-Fi and updates the time automatically when clocks change. Its companion app allows easy alarm adjustments via Bluetooth. Hatch also offers a Daylight Saving Assistant feature for its Baby Sound Machine ($100), which gradually shifts a child’s sleep schedule in small increments over several days without any single jarring change.
Lumie’s devices, including the Bodyclock Luxe 700FM ($259) and the Bodyclock Shine 300 ($169), require manual time and alarm adjustments each night since they operate without Wi-Fi or app connectivity. The trade-off is brightness. Lumie’s clocks produce a stronger light output than the Hatch units, which some users find more effective for waking.
The Practical Checklist
- Begin shifting alarms 15 to 20 minutes earlier starting two to three days before the change
- Adjust meal times, particularly breakfast and dinner, in parallel with the sleep schedule
- Use morning light exposure, natural or simulated, to reinforce the new wake time
- For children, consider devices with automated gradual schedule shifting like the Hatch Baby
- On Saturday night, complete the full clock transition and reset alarms to their target times
Sunrise alarm clocks are not a requirement, but they do remove one barrier. A noisy alarm in a dark room does little to help the brain accept that morning has arrived. Light does.
