Beat The Heat!

As temperatures climb into the mid- to upper 90s this week in Northwest Indiana (with the chance for triple-digit heat indexes!), it is important that you are aware of heat emergenices and what you can do to try to beat the heat.

Children, elderly, and obese people have a higher risk of developing heat illness. People taking certain medications or drinking alcohol also have a higher risk. However, even a top athlete in superb condition can succumb to heat illness if he or she ignores the warning signs.

If the problem isn't addressed, heat cramps (caused by loss of salt from heavy sweating) can lead to heat exhaustion (caused by dehydration ), which can progress to heatstroke. Heatstroke, the most serious of the three, can cause shock , brain damage, organ failure, and even death.

Prevention

• Wear loose-fitting, lightweight clothing in hot weather.
  
• Rest frequently and seek shade when possible.
  
• Avoid exercise or strenuous physical activity outside during hot or humid weather.
  
• Drink plenty of fluids every day. Drink more fluids before, during, and after physical activity.
  
• Be especially careful to avoid overheating if you are taking drugs that impair heat regulation, or if you are overweight or elderly.
  
• Be careful of hot cars in the summer. Allow the car to cool off before getting in.

First Aid

• Have the person lie down in a cool place. Raise the person's feet about 12 inches.
  
• Apply cool, wet cloths (or cool water directly) to the person's skin and use a fan to lower body temperature. Place cold compresses on the person's neck, groin, and armpits.
  
• If alert, give the person beverages to sip (such as Gatorade), or make a salted drink by adding a teaspoon of salt per quart of water. Give a half cup every 15 minutes. Cool water will do if salt beverages are not available.
  
• For muscle cramps , give beverages as above and massage affected muscles gently, but firmly, until they relax.
  
• If the person shows signs of shock (bluish lips and fingernails and decreased alertness ), starts having seizures , or loses consciousness, call 911 and give first aid as needed.
