Summer Safety: Preventing Heat Illness and Dehydration

Summer Safety: Preventing Heat Illness and Dehydration

As the summer heat intensifies, it’s crucial to prioritize safety, especially when working or engaging in activities outdoors. Heat illness, dehydration, and sun damage are serious concerns that can impact health and productivity. Understanding the signs, symptoms, and preventive measures can help ensure a safe and enjoyable summer. Here’s what you need to know, from Pavion Safety Director, Jim Tanler:

Recognizing Heat Illness

Heat illness can manifest in various forms, and symptoms may differ from person to person. Key signs to watch for include:

  • Headaches
  • Heat cramps
  • Weakness
  • Dizziness or nausea
  • Blurred vision
  • Fainting
  • Convulsions
  • Severe cases can lead to death

High humidity exacerbates these conditions and hampers the body’s ability to cool down through sweat evaporation. When temperatures rise above 85°F with 90% humidity, discomfort sets in for most people. At 92°F and 90% humidity, heat exhaustion becomes a significant risk.

Improving Heat Tolerance

To improve your tolerance to heat:

  • Gradually increase exposure to hot environments.
  • Stay hydrated by drinking plenty of water. Supplement water with sports drinks like Gatorade after consuming at least two cups of water to replenish electrolytes.
  • Consume foods high in acetic acid, such as citrus fruits and pickles, which can enhance heat tolerance.

What to Avoid

Certain beverages and habits can undermine your efforts to stay hydrated:

  • Avoid caffeine-rich drinks like coffee and energy drinks, which act as diuretics and increase fluid loss.
  • Limit alcohol intake, as it also has a dehydrating effect.
  • Be cautious with soft drinks and fruit juices, as their high sugar content can slow down water absorption and fail to adequately hydrate.

Hydration Best Practices

For those working in hot, humid environments:

  • Drink about 8 bottles of water daily, balanced with sports drinks. The recommended ratio is two bottles of water to one bottle of a sports drink.
  • Monitor urine color as clear urine is a good indicator of adequate hydration.
  • Eat balanced meals that include a mix of carbohydrates, electrolytes, and water to maintain optimal body function.
  • Listen to your body. If you experience a headache, try drinking water before taking medication.

Remember, staying hydrated is vital. Stay safe, and enjoy a healthy, productive summer!
