(COLUMBUS, Neb.) – While you're soaking up some fun this summer, don't forget to protect your skin and 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 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 these steps 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, and reapply every two hours. There are both chemical and mineral sunscreens; mineral sunscreens are better for people with highly sensitive skin or acne, while chemical sunscreens are more water-resistant.
• Seek the shade. Try to limit sun exposure between 10 a.m. and 4 p.m., which is 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. There is specific UV-protective clothing (called UPF clothing) that can help block the sun's rays, in addition to the physical blockage the clothing gives you.

It's also wise to check your skin regularly for signs of cancer: new or changing growths; sores that bleed or don't heal; rough areas; or moles that change in size, shape or color. See your doctor if you notice any concerning signs, such as moles that contain various colors, are an odd shape, have irregular borders or contain various colors.

Stay cool

Extreme temperatures can also bring on heat-related illnesses such as heatstroke, which is a medical emergency. To help reduce your risk, drink plenty of water and spend time in air-conditioned areas. It’s also important to know the possible warning signs of heat illness, such as dizziness; nausea; fainting; confusion; or hot, dry skin. If you notice these symptoms in someone else, call 911 and then move the person to shade and cool them down.
