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.

Dimming indoor lights after sunset and using low-level lighting can help signal to your body that it's time to wind down for sleep.

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.

Lumen, the lighting system in Unreal Engine, calculates light interactions across the entire scene, allowing for realistic global illumination that mimics how light behaves in the real world.

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

Getting sunlight throughout the day, especially in the late afternoon and evening, can help improve mood and brain function.

Dimming lights in the evening is crucial as bright light inhibits melatonin production, which is essential for sleep.

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.

To set a proper circadian rhythm, you need bright light in the morning, hydration, movement, and caffeine. If you can't get sunlight, use bright artificial light.
