What protective equipment and precautions can reduce injury in this sport? 100 Chapter 4 Physical Activity for Life Helmets, goggles, and gloves are proper equip- ment when snowboarding. cold weather as it is in hot weather. Two specific health risks from cold weather are particularly important to keep in mind: frostbite and hypothermia. is a condition that results when body tissues become frozen, and it requires professional medical treatment. You can avoid frostbite by dressing warmly and covering all exposed skin—especially the ears, face, feet, and fingers, where frostbite most often occurs. An early warning sign of frostbite, called frostnip, is a whitening of the skin of the toes, fingers, nose, or ears. If this happens or if you notice a lack of feeling in any exposed area, get indoors right away and warm the area with warm water.

is a condition in which body temperature becomes dangerously low. It is usually associated with cold weather, but it also can result from lengthy exposure to wind or rain or from submersion in cold water. When hypothermia occurs, the body loses the ability to warm itself. As body temperature drops, the brain cannot function and body systems begin to shut down. A person with this condition may become dis- oriented and lose motor control. Because hypothermia can lead to death, it requires immediate medical attention. When participating in cold-weather activities, pay attention to your body. Shivering is a sign that your body is losing heat. If you begin to feel cold or to shiver, go to a warm, dry place; wrap your- self in a blanket; and drink warm liquids to slowly raise your body temperature. Protecting Yourself from Sun and Wind Prolonged exposure to sun and wind is another weather- related risk of outdoor physical activity. Windburn occurs when skin is exposed to freezing wind, causing it to become red, tight, and sore to the touch. Reduce the risk of windburn by wearing protective clothing and using lip balm. The sun’s UV rays cause sunburn, a burning of the outer layers of the skin. Mild sunburn makes your skin red and slightly sore. Severe sunburn causes blistering of the skin, swelling, and pain. In addition to increasing the risk of sunburn, repeated or prolonged exposure to the sun speeds the skin’s aging process and increases your risk of developing skin cancer. The most dan- gerous hours for UV exposure are from 10:00 A . M . to 4:00 P . M . To protect yourself against sunburn: Cover as much of the body with clothing as possible when outdoors and wear broad-brimmed hats on sunny days. Use sunscreen and lip balm with a sun protection factor (SPF) of at least 15. The SPF number indicates the sunscreen’s ability to screen out the sun’s harmful UV rays. Because UV rays pene- trate clouds, you need to wear sunscreen on cloudy days, too.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
