Every March and November, my inbox floods with emails from folks asking how to ease into the time change and, as a sleep specialist, itâs my job to reassure them. Generally, I find âspringing forwardâ is easier than falling back for two reasons: 1) We are waking up an hour later for this time change instead of an hour earlier in the fall. 2) We get more evening light to enjoy after school and work. However, there are challenges with the onset of daylight saving time, as with any time change. The clocks may simply shift forward, but your âbody clockâ will not. Your biological rhythm of hormone release that determines when you feel sleepy and when you feel alert, syncs with the natural 24-hour cycle of day and night. Your bodyâs natural intelligence is quite adaptable to seasonal shifts in light but it responds much slower to changes than the hands of a clock. Essentially, itâs like the entire country waking up with an hour of jet lag Sunday morning.
