Morning Light, Night Dark
Insight
The cheapest sleep aid available is outside, free, and operational by about 7 am: daylight. Ten minutes of morning light anchors the body clock more reliably than almost anything sold for the purpose.
Why it works
Light is the master signal of the circadian system. Bright light early sets the timer for evening sleepiness; dim light late protects it. Most modern days run the sequence backwards and then wonder why sleep won't start.
Practical takeaway
This week, get ten minutes of outdoor light within an hour of waking — coffee on the step, a walk to the letterbox. Then dim the evening and let the clock do its work.
Good question to ask someone
What did you see first this morning — daylight, or a screen?
