Sun Safety
The ozone layer isn’t what it used to be, and with growing concerns about environmental pollution causing damage, we all need to beware and be aware of damaging our skin. Other concerns for gardeners are heat and sun stroke. Here are some very important sun safety tips to remember when spending long periods out of doors.
- Reduce your time in the midday sun. UV rays are strongest between 11:00 a.m. and 4:00 p.m., so try to plan your outdoor activities before or after these times. And remember, ultraviolet radiation may be increased by reflective surfaces such as water, concrete, or sand.
- Look for shady trees and canopies, especially during peak UVR times from 11:00 a.m. to 4:00 p.m. Take a shady umbrella with you to the beach or other outdoor activities.
- Protect your eyes and shade your face with UV absorbent sunglasses and a broad brimmed hat. Wear clothing to cover your arms and legs. Although knee length shorts don't protect as well as long pants, they are better than very short shorts.
- Look for a sunscreen product with both UVB and UVA protection and a sun protection factor (SPF) of 15 or greater. Apply sunscreen at least 20 minutes before going into the sun, and reapply generously after swimming or physical activity. Remember, your skin doesn't have to be hot to burn, so don't be fooled by cloudy or overcast weather.
A more serious problem is heat or sun stress. When conditions outside are hot and humid, your body must work harder to get rid of excess heat. Individuals over 40 need to take extra care as our ability to sweat declines as we age. If the body overheats, these are two conditions that may occur:
Heat exhaustion
If you don’t drink enough water and your salt intake is low, your body cannot cool itself. Symptoms include heavy sweating, cool, moist skin, body tempature over 38 degrees, weak pulse, and low blood pressure. The person will most likely feel tired, weak, clumsy, upset or confused. They will be thirsty and pant or breathe rapidly. Heat exhaustion can lead to heat stroke which may be fatal. Move to a cool shaded area and loosen clothing. Drink cool, lightly salted water and try to be near a breeze.
Heat Stroke
Once the body uses up all of its water and salt, you body can no longer sweat, and your temperature can rise quickly. You have heatstroke if your body temperature is over 41 degrees, you exhibit weakness, confusion, distress or strange behaviour, you have hot, dry, red skin, your pulse is rapid or you have a headache or are dizzy.
Get medical help immediately.
