THE BIOLOGY OF WIND-DOWN
The body’s circadian rhythm is heavilyinfluenced by light. As evening approaches, melatonin production increases,preparing the body for sleep. Artificial light — particularly blue light — candisrupt this process.
WHY BLUE LIGHT MATTERS
Blue light, emitted from phones, laptopsand LED lighting, can suppress melatonin, delay sleep onset and reduce sleepquality.
THE MODERN PROBLEM
Modern environments expose us to brightlight late into the evening, confusing the body into thinking it is stilldaytime.
DESIGNING AN EFFECTIVE EVENING ROUTINE
Small, consistent changes can significantlyimprove sleep quality.
- Dim the lights early
Use warm, low-level lighting in theevening.
- Limit screen exposure
Reduce screen use or brightness in the hourbefore bed.
- Use blue light blocking glasses
High-quality amber or red-tinted lenses canmeaningfully reduce blue light exposure and support melatonin production.
- Create a wind-down routine
Establish a consistent sequence of relaxingactivities before bed.
- Be mindful of alcohol and stimulation
Alcohol and late stimulation can disruptsleep architecture.
