This is not really an accurate statement because we are “outside” much more than we think. Anytime you can see the sun, the sun can see you. Being by a window, riding in a car, and/or sitting in an office by a window is considered “outside” for your skin and the sun. Most windows only block UVB light, not UVA light. UVA stays the same all year long and can penetrate much deeper than UVB. UVA causes skin aging and skin cancer. That is one of the main reason why we recommend wearing sun protection all year long.

The photo included on the following page is a 69 year-old delivery truck driver with unilateral dermatoheliosis—severe damage from ultraviolet rays on the left side of his face with significant photo damage, wrinkling, pigment change and even a change in his eye anatomy. This man drove truck for 28 years and wasn’t “outside” very often. Just another example of the importance of wearing sunscreen daily, even in the winter and even if you’re not spending much time “outside.”
