Re-Timer light therapy for sleep

Light therapy (or phototherapy) involves exposure to specific wavelengths of light for a prescribed amount of time at a specific time of day.

Wearing Re-Timer for 30-45 minutes (morning or evening) will help you take control of your sleep, naturally.

Lifestyle factors

  • Shift work
    • Working different shifts requires you to adjust your sleep-wake times to accommodate your work life. Often this means having to sleep during the day which is contrary to your body’s natural rhythm, or experiencing fatigue during your shift.
  • Travel
    • Frequent travel may require you to cross multiple time zones. This can disrupt your existing sleep-wake rhythm and result in you feeling jet lagged and unable to sleep.
  • Seasonality
    • Lack of morning light during the winter can cause you to have trouble sleeping at night and then waking in the morning. This lack of morning light may also contribute to Winter Blues.

For each of these lifestyle factors, appropriately timed bright light therapy is effective in altering circadian rhythm timing and consequently improving sleep.
