Warm lights after 8 pm: did we wind down faster?
Sofia Mbeki · Aug 3, 2026
Hypothesis
Switching to warm, dim lamps after 8 pm will help us feel sleepy sooner.
Method
Three of us spent one week with normal lighting, then two weeks with warm bulbs and lamps only after 8 pm. We kept simple diaries of our sleepiness and the time we fell asleep. This is a home test, not medical research.
Result
Two of us felt sleepy earlier and liked the evenings more. One of us noticed no difference. Screen use seemed to matter more than bulb colour.
Mixed
Mixed. It's pleasant and cheap, but put the phone down too.
