Each spring, the start of Daylight Saving Time shifts the clock forward by one hour. While it may seem minor, this change can significantly affect your body’s natural sleep-wake cycle.
At Lung & Sleep Specialists, many patients report sleep disruptions during this transition.
How the Time Change Affects Sleep
Your body operates on a circadian rhythm, which regulates sleep, hormones, and metabolism. Even a one-hour shift can temporarily throw this rhythm off balance.
Common effects include:
-
Difficulty falling asleep
-
Feeling tired in the morning
-
Reduced sleep quality
-
Daytime fatigue and irritability
For patients with sleep disorders such as sleep apnea or insomnia, the adjustment can be even more noticeable.
Tips to Adjust to the Time Change
You can help your body adapt by:
-
Going to bed slightly earlier a few days before the time change
-
Getting morning sunlight exposure
-
Avoiding caffeine late in the day
-
Maintaining a consistent bedtime routine
When Sleep Problems Persist
If fatigue, snoring, or disrupted sleep continues long after the time change, it may indicate an underlying sleep disorder.
Sleep studies and evaluations can help diagnose conditions such as sleep apnea, allowing for treatment that improves sleep quality and daytime energy.
