Open curtains or get outside soon after waking. In dark seasons, use bright indoor light or an appropriate light box with medical guidance when needed.
The room may still be telling you it is night
You can complete an alarm and remain in a dark bedroom where every cue says go back to sleep. Open the curtains, turn on the room lights, or step outside. Outdoor light is often much brighter than indoor light even on a cloudy day.
Put a sky-photo or window task at the end of the alarm if that is safe and practical. The useful part isn't the photograph; it is arriving where morning light can reach you.
Timing and eyes matter
Morning light can help shift body timing earlier, while bright late-evening light can push the other way. The effect depends on timing and the person, so more isn't always better.
If you have an eye condition, bipolar disorder, take light-sensitive medication, or are considering a strong light box, ask a qualified professional. Ordinary daylight is a useful habit; treatment-level light deserves care.
Common questions
How long should I get morning light?
There is no single dose for everyone. Start with a practical period outside or near bright daylight and keep it consistent.
Does light through a window count?
It can help, though outdoor light is usually much brighter. Never stare directly at the sun.
