Coping with the Heat

Exposure to intense heat, sun, and high humidity can cause heat-related illnesses, such as heat exhaustion, heat cramps, and heat stroke (also known as sun stroke). As the body works to cool itself under extreme or prolonged heat, blood rushes to the surface of your skin. As a result, less blood reaches your brain, muscles, and other organs. This can interfere with both your physical strength and your mental functions, leading, in some cases, to serious danger.

During extremely hot weather, precautions should be taken to avoid heat-related complications. Those who take certain medications for high blood pressure, depression, or allergy are at greater risk. Use common sense as you go about your daily routine. Eat a balanced diet and drink plenty of fluids; at least 8 to 10 tall glasses of liquid each day. You should be drinking enough fluid that your urine is clear or pale yellow. Avoid prolonged outdoor activities such as hard labor, jogging, tennis, racquetball, etc. If you feel you must exercise, swimming is recommended. Remember, if you must do heavy activity, such as "move-in" day on campus, take regular breaks in a cool place. Dress in lightweight, well-ventilated clothing, and wear a wide-brimmed hat. Use sunscreen to prevent sunburn, which can hinder the skin’s ability to cool itself. It is important to avoid alcohol and caffeine, which cause dehydration. Clear liquids are best - preferably water. Other good choices include lemonade and juices.

HEAT CRAMPS
Heat cramp symptoms include:

HEAT EXHAUSTION
Heat exhaustion is a condition brought on when the body's temperature control system is overloaded. The body normally cools itself by sweating, but sometimes sweating is not enough.

Signs and symptoms of heat exhaustion are:

To treat heat exhaustion:

Gradual fatigue and weakness

Go to a cool or shady area.

Anxiety and nausea

Lie down flat or with head slightly elevated.

Profuse sweating with cold, clammy skin

Remove excess clothing.

Pale color

Drink small amounts of water every few minutes.  Sports drinks (with less than 6% glucose) help replace the salt which has been lost.  NO alcohol or caffeine. Plain water with 1 teaspoon salt added per quart.

Dizziness, headache, blurred vision

Place a bag of ice or cool cloth on forehead, back of neck, groin, and under armpits. Do not use an alcohol pad.

Muscle cramps

Allow adequate time to rest.

Fainting

Avoid heavy activity for the rest of the day.

Increased pulse rate

HEAT STROKE
Heat stroke is a more serious condition in which the body fails at regulating its own temperature. This condition happens abruptly and is considered an emergency.

Signs and symptoms of heat stroke are:

If any of these symptoms are present:

Headache, dizziness

Call 9-911(campus phone) or 911 (non-campus phone) for emergency assistance as soon as possible.

Absence of sweating

Place the person in a shady or air-conditioned area.

Hot, red and dry skin

Remove excess clothing.

Place in a cool bath if person conscious and someone in constant attendance. Alternatively, sponge skin with cool water. Place a bag of ice or cool cloth on forehead, back of neck, groin, and under armpits. DO NOT use an alcohol rub.

Elevated temperature

Sponge with cool water.

Unconsciousness or markedly abnormal mental status

If the person is conscious and alert, offer sips of liquids.

Seizures Wait for emergency help to arrive.  If unconscious  or confused, do not give fluids because of danger of choking.

Call 9-911 (campus phone) or 911 (non- campus phone)
