Why am I so tired after daylight savings time ends?

You are likely feeling tired as a result of a little disruption in your body’s inner clock, known as your circadian rhythm.

This internal timer follows a 24-hour cycle, dictating when you sleep and when you wake, and it’s heavily influenced by light.

When daylight saving time ends, and we turn the clocks back, it suddenly gets darker earlier. This shift can throw off your sleep routine in a couple of ways.

Firstly, the dimmer evenings might trick your body into staying up later, messing up your sleep-wake cycle.

Secondly, the change in light exposure can mess with the production of melatonin, the hormone that tells your body it’s time to hit the hay.

This mismatch between your body’s clock and the outside world can lead to something called sleep debt. That’s when you accumulate a shortfall in your sleep quota, leaving you feeling tired, sluggish, and struggling to concentrate during the day.

But fear not! Your body is pretty good at adapting. Within a few days to a week, things usually start to improve as you adjust to the new daylight schedule. In the meantime, there are a few tricks you can try to help ease the transition.

Gradually adjust your sleep schedule by going to bed a little earlier each night until you hit your desired bedtime. Try to soak up some morning sunlight to help reset your internal clock.

And, perhaps most importantly, stick to a consistent sleep routine, hitting the hay and waking up at the same time every day, even on weekends.

With a bit of patience and a few adjustments, you’ll soon be back to your bright-eyed and bushy-tailed self.
