That extra hour of sleep might feel great — but it can also throw off your internal clock and your medication routine. Learn how daylight saving time impacts your body and the science behind proper med timing.
Your circadian rhythm is a 24-hour internal clock that regulates everything from sleep and body temperature to hormone release and digestion. It’s heavily influenced by light exposure — so when we “fall back” an hour, the sudden change can throw your rhythm off.
This can lead to short-term sleep disruption, mood swings, reduced alertness, and even digestive issues.
Why Medication Timing Matters
Many medications are timed to match your body’s natural rhythms. For example:
- Blood pressure medications are often taken in the morning to prevent early-day spikes
- Sleep aids are taken before bedtime based on melatonin production
- Insulin and diabetes medications are timed around meals and activity levels
Disrupting your schedule by even an hour can cause subtle changes in how your body responds to these medications.
The Role of Liver Enzymes
Your liver’s ability to process medications — known as drug metabolism — also follows a circadian pattern. Enzyme activity can peak or dip at different times of day, so taking your medications at an unusual hour may alter how effectively they’re absorbed or how long they stay in your system.
Tips for a Smooth Time Change Transition
- Gradually adjust your medication schedule by 15 minutes over a few days before the time change
- Set reminders or alarms to help stay consistent with dosing
- Keep meal and sleep schedules regular to support your circadian rhythm
- Talk to your pharmacist before changing your medication timing
