While you're soaking up some fun this summer, don't forget to protect the skin you're in and your overall health.
Unlike visible light, ultraviolet (UV) sunrays pack enough energy to damage the DNA in your skin cells. This can lead to skin cancer, including basal and squamous cell skin cancers (the most common kinds) and melanoma (the most deadly kind). UV skin damage can also cause you to have more wrinkles or other signs of aging, such as dark spots and leathery skin.
Save your skin
You can help reduce your skin cancer risk by taking steps like these when you spend time outdoors:
Wear sunscreen. Apply a broad-spectrum sunscreen with a sun protection factor (SPF) of at least 30 to exposed areas of your skin. Reapply every two hours.
Seek the shade. Try to limit sun exposure between 10 a.m. and 4 p.m., when the sun's rays are strongest.
Cover up. Shield your skin with a wide-brimmed hat, sunglasses that block both UVA and UVB rays, and a long-sleeved shirt and pants. Consider buying clothing made with fabrics that block UV rays.
It's also wise to check your skin regularly for signs of cancer, such as:
• New or changing growths.
• Sores that bleed or don't heal.
• A rough area.
• A mole that's changing in size, shape or color. For instance, it may have irregular borders or an odd shape. It could contain various colors or be larger than a pencil eraser.
See your doctor if you notice any concerning signs.
Stay cool
Extreme temperatures can also bring on heat-related illnesses like heatstroke, which is a medical emergency. To help reduce your risk, drink plenty of water and spend time in air-conditioned areas. And know the possible warning signs, such as dizziness, nausea, fainting, confusion or hot, dry skin. If you notice these in someone you're with, call 911, and then move the person to shade and cool them down.
