Stay safe on the water…July 7, 2010
Summer is here on the Chesapeake and the heat seems to have settled in. Being out on the water seems like the perfect idea this time of year. However, even while boating, one must be careful not to over-do it. Sunscreen is a must, and should be reapplied frequently throughout the day. Hats, light colored clothing and drinking plenty of water will help prevent heat related illness. Read on for more info…
Reducing Your Risks
1. Drink lots of cool water
Drink lots of cool water, more than you think you need, when the weather is hot and humid. (High humidity makes heat injuries more likely because perspiration does not evaporate from the skin as quickly; this causes the body to cool down more slowly.) Water is best; fruit and vegetable juices are good, too.
Drink at least a gallon of liquid a day (about 16 glasses) when the outside temperature is above 90 degrees and you’re out on your boat. This will mean drinking 1 1/2 times as much liquid as your thirst signals you to drink.
Overweight people need even more water during summer than average weight people.
Do not drink beer or other alcoholic beverages, coffee, tea or other drinks containing caffeine because they cause you to lose fluid.
2. Maintain normal salt intake
Maintain normal salt intake in your diet (1 1/2 teaspoons or less per day). If you have heart disease or high blood pressure, ask your doctor about your salt intake.
3. Stay cool
Wear light-colored clothes that are loosely woven and absorbent. Cotton is best; it absorbs 40 percent of its weight in moisture. Most synthetic (manmade) materials trap body heat and are not absorbent. Wear a hat to shade your head. Wet bandannas around the neck help cool your entire body. Now is the time to give the kids squirt guns!
5. Older people are more sensitive to heat
Realize that older people are more sensitive to heat and may easily suffer heat-related sickness. Also, anyone with diabetes, heart disease, arteriosclerosis, high blood pressure, or Parkinson’s Disease is more sensitive to the effects of heat.
Types of Heat-Related Problems
- Heat Cramps – symptoms include painful cramping and spasms of legs, arms and/or abdominal (stomach) muscles.
- Heat Exhaustion – symptoms include feeling tired, weak, and dizzy; headache, nausea and possible vomiting. Heavy perspiration; skin feels moist.
- Heat Stroke – symptoms include feeling tired, weak and dizzy. Skin feels hot and dry, even under armpits; appears red and flushed. May become delirious and unconscious. This is a life threatening situation! Call 911.
Treating Heat-Related Problems
Heat Cramps
- Rest in a cool, shaded place.
- Drink cool water slowly (4 ounces which is equal to 1/2 cup of fluid, every 15 minutes)
- Stretch the muscle lightly.
- Massage the area gently.
Heat Exhaustion
- Rest in a cool, shaded place.
- Lie down with feet raised 8 to 12 inches.
- Loosen all clothing.
- Drink cool water (4 ounces, which is equal to 1/2 cup of fluid, every 15 minutes).
- Place cool, wet clothes on forehead and body.
