How to read XP

Each score is for this protocol and that specific goal, not a general rating.

XP combines how reliable the research is with how much difference it usually makes. Higher means stronger evidence for that protocol and that goal.

How to do it

Within the first hour or two after you wake up, outdoors.

1
Step outside
Do it soon after waking. A doorstep or balcony works; windows and car glass filter out much of the light.
2
Look around, not at the sun
Daylight reaches your eyes anyway. Never stare at the sun.
3
Stay 5–20 minutes
About 5–10 on a clear day, 15–20 when it is overcast.
4
Skip the sunglasses
Regular glasses or contact lenses are fine.
5
Repeat most days
Weekends included.

The good-enough version

Drink your morning coffee on the doorstep or balcony for five minutes.

Common mistakes

Staring at the sun
Counting light through a window
Wearing sunglasses the whole time
Leaving it until late morning

Your journey

Alertness can lift the same day. Sleep timing takes a week or two. An estimate from the studies' timelines, not a promise: everyone responds differently.

Focus & Alertness

Within a day

Sleep Quality

Day 3 → Week 2

Mood & Depression

Day 7 → Week 4

From the first noticeable effect to roughly full strength. Colour follows the XP tier of each benefit.

Make it a habit

These gains come from steady use, not a single dose. Keep Morning Sunlight in your routine for about week 4 before you judge it.

Safety

What to know before you try Morning Sunlight.

Safety rating

Well tolerated

Mild effects, if any.

Never stare at the sunYou only need daylight, not the sun itself. Look around normally.
Strong sun, longer staysIf you stay out longer than 10–15 minutes when the sun is strong, protect your skin as you normally would.

Check with a doctor first if you have an eye condition, take medicines that make you sensitive to sunlight, or have had skin cancer.
