Get 5 minutes of outdoor light before noon

Step outside in the morning and let daylight reach your eyes.

Why it helps

Natural light in the morning helps set your body clock, and many people find they sleep better when they get it regularly. Even a cloudy sky is far brighter than indoor lighting.

How to do it

1. Go outside within a couple of hours of waking.
2. Face roughly toward the sky, not the sun, and keep your eyes open.
3. Stay for at least five minutes, standing or walking.

Make it easier

Stand by an open door or window for five minutes.

Make it harder

Take your whole morning coffee outside, about 15 minutes.

Never look directly at the sun.
