5 Ways Sunlight and Vitamin D Improve Your Focus and Mood

The shift to remote work has left us divided. Some of us want to remain remote forever, others can’t wait to get back to the office, and some are calling for a hybrid model. There are pros and cons of each, but one downside of working from home has consistently been overlooked — morning sunlight.

For millions of people around the world, their daily commute has been reduced to a short stroll from the bedroom to the study (or the kitchen table). While convenient, this can come at a significant cost to our mood, sleep, and focus.

Sunlight has long been vilified for the deleterious effects of over-exposure, and while we must indeed be sun-smart, the WHO found that ultraviolet rays (UVR) account for only 0.1% of the total global burden of disease.

Direct-sunlight exposure (as opposed to indirect sunlight exposure through a window) plays a number of critical and foundational roles when it comes to optimizing our health and mental performance.

In this video, I explore five benefits of sunlight, and how to get more of the sun's vitamin-D boosting goodness into your day.
