Spring Forward: How to Prepare for Daylight Saving Time and Protect Your Sleep

Twice a year, we adjust our clocks — but our bodies don’t adjust as quickly.

When we “spring forward” for Daylight Saving Time (DST), we lose one hour of sleep. While it may seem minor, that lost hour can disrupt your internal body clock, impact your mood, reduce productivity, and worsen underlying sleep disorders such as sleep apnea and insomnia.

At Comprehensive Sleep Care Center, we see firsthand how even small changes in sleep patterns can affect overall health. Here’s how to prepare for the time change and protect your sleep.

Why the Spring Time Change Affects Your Body

Your body operates on a natural 24-hour rhythm called the circadian rhythm. This internal clock regulates:

  • Sleep and wake cycles

  • Hormone production

  • Body temperature

  • Metabolism

  • Mood and cognitive performance

When the clock suddenly shifts forward by an hour, your circadian rhythm becomes misaligned. This can lead to:

  • Difficulty falling asleep

  • Trouble waking up

  • Daytime fatigue

  • Brain fog

  • Increased irritability

  • Reduced immune function

Studies also show a temporary increase in workplace accidents and even cardiovascular events in the days following the spring time change.

If you already struggle with sleep apnea, insomnia, narcolepsy, or restless legs syndrome, the time change can intensify symptoms.

7 Smart Ways to Prepare for “Spring Forward”

1. Gradually Adjust Your Bedtime

Start 4–5 days before the time change.
Go to bed 15–20 minutes earlier each night to ease into the new schedule.

2. Shift Your Wake-Up Time

Wake up 15–20 minutes earlier each morning leading up to the change. This helps your body slowly recalibrate.

3. Get Morning Sunlight

Exposure to natural light in the morning helps reset your circadian rhythm. Step outside within 30 minutes of waking whenever possible.

4. Avoid Late-Night Screens

Blue light from phones, tablets, and TVs suppresses melatonin production. Turn off electronics at least one hour before bedtime.

5. Limit Caffeine and Alcohol

Avoid caffeine after 2 PM. While alcohol may make you sleepy, it disrupts sleep quality and can worsen sleep apnea.

6. Stick to a Consistent Routine

Maintain consistent meal times, exercise habits, and bedtime routines to help stabilize your internal clock.

7. Prioritize Sleep Hygiene

  • Keep your bedroom cool and dark

  • Use blackout curtains

  • Avoid heavy meals before bed

  • Practice relaxation techniques

Special Considerations for Sleep Apnea Patients

If you use CPAP or Oral Appliance Therapy, consistency is critical.

The time change can:

  • Reduce CPAP compliance

  • Increase daytime sleepiness

  • Trigger headaches or brain fog

If you notice worsening symptoms after the time change, it may indicate your treatment settings need review.

Comprehensive Sleep Care Center specializes in diagnosing and treating:

  • Obstructive Sleep Apnea (OSA)

  • Central Sleep Apnea

  • Insomnia

  • Hypersomnia

  • Circadian Rhythm Disorders

When to Seek Help

If you experience:

  • Persistent fatigue

  • Loud snoring

  • Gasping during sleep

  • Morning headaches

  • Difficulty concentrating

It may not just be the time change — it could be an undiagnosed sleep disorder.

Sleep is foundational to heart health, brain function, immune strength, and longevity.
