Heat Exhaustion!

combat summer heat

When it is hot outside your body cools itself by sweating. Your body cools as the sweat evaporates from your skin.  But if you are overexposed to heat or are doing strenuous physical activity your body loses its ability to cool itself properly.  This is called heat exhaustion. This can be caused by loss of water and electrolytes through sweating as a result of hot, sunny, humid weather, and physical exertion in that weather.  Elderly and children are at greater risk due their body’s inability to regulate body temperature, and lack of cool air. Drugs, such as, ecstasy, cocaine and amphetamines, can cause rapid rise in body temp.

Symptoms of heat exhaustion include, nausea, dizziness, irritability, headache, thirst, weakness, high body temperature, excessive sweating, decreased urine output, confusion, vomiting, muscle cramps, which is related to low blood sodium and potassium.

Heat exhaustion can occur in the elderly because they are less likely to drink enough fluids or sense significant changes in temperature. Heat exhaustion in kids can occur as babies and young kids are very sensitive to extreme heat.  Keep cool and hydrated. Don’t leave them in the car, even with the window open.

Treatment- When the temp is over 91 you need to take precautions

  1. Go to a cool area
  2. Remove layers of clothes
  3. Fanning and wet towels
  4. Dizzy may be related to low BP, so lay down and put your feet up
  5. Drink water or sport drink, and sip slowly
  6. If you have continuous vomiting get medical attention immediately

Heat exhaustion can progress to heat stroke, which is a medical emergency.

Heat Stroke (Sun Stroke) occurs when there is a high body temp of 103 or higher. It is considered hyperthermia without fever.  Symptoms include hot, red, dry or moist skin, rapid and strong pulse, and loss of consciousness.  Call 911, move person to cool area, cool person down with cool cloths or bath, DO NOT GIVE FLUIDS.

Those at risk for heat stroke are those wearing dark, heavy, padded clothes, and over dressing, has a high percentage of body fat, dehydration, Fever, beta blockers (cardiac medication), antipsychotic medication, alcohol and caffeine.

The most important thing to remember is to not wait until you are thirsty to drink fluids.

Dehydration!

Staying well hydrated during the summer.

Dehydration occurs when you use or lose more fluids than you are taking into your body. This results in your body not being able to perform its usual functions that require proper fluid intake. If you don’t replace these fluids, you become dehydrated. We lose water and salt daily through vapor from breathing, sweat, urine, and stool.

Causes include poor fluid intake due to illness or mouth sores, or nausea, intense physical activity,hot weather, severe diarrhea or vomiting, fever, sweating, poor fluid intake with increased activity and hot weather, and increased urination due to a medical condition such as diabetes or medications.

Mild to Moderate symptoms include dry, sticky mouth, thirst, decrease in urination,fatigue, no wet diapers for at least 3 hours, few or no tears when crying, dry skin, headache, constipation, dizziness, and muscle cramps.

Severe symptoms are considered a medical emergency. If you experience great thirst, are irritable or confused, feel weak, have a very dry mouth, little or no urination or sweating, eyes look sunken in, a low blood pressure, rapid heart, rapid breathing, tenting of skin, fever, fainting, and a swollen tongue, you need immediate medical attention.

Complications of dehydration include heat exhaustion or heat stroke, swelling of the brain, seizures, low blood volume shock (Hypovolemic Shock), kidney failure, coma and death.

Treatment for kids includes small frequent sips of rehydrating solutions, such as Pedialyte, popsicles, and water. In adults, Gatorade, PowerAde, water, and ice chips are effective. Additionally, wearing loose clothes, air conditioning, fans, cool wet towels, spray bottle with water, avoid alcohol, caffeine. You can also break up exposure to heat by spending 10-20 min in heat then going inside to get cool.
Milk, caffeinated drinks, fruit juices and gelatins don’t relieve dehydration and can worsen diarrhea.
