Sunscreen and outdoors are synonyms

Sunscreen and outdoors are not synonyms; they refer to different concepts. Sunscreen is a product designed to protect the skin from harmful ultraviolet (UV) rays from the sun, while "outdoors" refers to the natural environment outside, typically where people engage in activities such as hiking, picnicking, or playing sports. Although sunscreen is often used when spending time outdoors, the two terms are related but distinct.
