Notice daylight in your everyday space
Daylight, view and routine can interact. This page asks you to observe your own experience without promising a specific effect.
Spend a short, comfortable time near natural light or outside when safe and practical.
Open my labWhat to notice
Note weather, time of day and whether you also moved or rested.
Record a 1–10 daily rating and whether you tried the activity. A missed day is useful context; it does not erase the rest of your week. At the first checkpoint, you can continue for seven or fourteen days, or choose something else.
How to interpret your result
Avoid claiming that light alone caused a change from a week of self-ratings.
Keep your original prediction separate from the daily ratings. Your starting rating, number of observations and changing circumstances all matter. A personal week can reveal a pattern worth exploring, but it cannot establish cause or statistical significance.
Evidence and context
This guide describes a small personal practice. For the wider research context, see Nature exposure and mental health: systematic review. Research findings describe groups and study conditions; your lab records describe your own experience.
