Don't Fry Day, occurring each May 23 before Memorial Day, emphasizes sun safety and skin cancer prevention. Founded by the National Council on Skin Cancer Prevention, the day promotes sun protection and awareness of skin cancer risks, the most common cancer in the U.S. Practical tips include using broad-spectrum SPF 30+ sunscreen, seeking shade, wearing protective clothing, and avoiding tanning beds. Observance encourages community participation in educational events to foster awareness and promote sun-safe habits.
