Getting sunlight in my eyes first thing in the morning is vital for mental and physical health, even on cloudy days, as it stimulates alertness.

Getting outside for about 5 to 10 minutes every morning is extremely important, even if it's cloudy, as it provides more photon energy than bright indoor lights.

To support your circadian clock, get sunlight in your eyes early in the day and whenever you want to feel awake, as getting two hours a day of outdoor time without sunglasses significantly reduces the probability of developing myopia, or nearsightedness.

Every person should ideally view bright light, preferably sunlight, within 30 minutes to an hour of waking up to optimize health.

Viewing bright sunlight within the first 30 to 60 minutes after waking triggers a cortisol increase, which is essential for alertness and focus throughout the day.

If you miss a day of morning sunlight, try to get twice as much sunlight exposure the following day to compensate.

Get outside for morning sunlight viewing at least 80% of the days of your life to enhance wakefulness and sleep quality.

If you wake up before sunrise, turn on bright artificial lights to help you stay awake, but once the sun rises, get outside to view sunlight for optimal wakefulness.

Spending at least 10 minutes a day looking at distant objects, such as a horizon, is beneficial for keeping the lens of the eye elastic and the eye muscles strong.
