Changing your sleep and wake times on the weekend is like giving yourself jet lag, which wrecks your metabolism, reaction time, and mood.

Your brain interprets bright overhead lights as the midday sun, which disrupts the natural signals for winding down in the evening.

Prioritize morning sun to regulate sleep cycle

Getting 10 to 30 minutes of natural sunlight in your eyes during the first hour of waking is the single most important trigger for your entire sleep cycle.
