First thing in the morning look at the sun or bright blue overhead lights


The long descriptionMorning light exposure initiates a precise neurochemical chain: photons hit retinal cells, signaling the Suprachiasmatic Nucleus (SCN)—the brain's master clock. This triggers an immediate, healthy cortisol pulse for wakefulness while simultaneously setting a "timer" for melatonin release 16 hours later. Aim for 5 minutes of outdoor early in the morning or direct sunlight in the eye for a few seconds.
