Hot Weather Safety

Warning signs of dehydration or heatstroke:

  • Headaches
  • Dry mouth
  • Dizziness
  • Difficulty breathing
  • Fatigue or weakness
  • Nausea or vomiting
  • Fast heart rate
  • Impaired judgment
  • Muscle cramps
  • High body temperature – a temperature over 104.5° F indicates heatstroke

Tips for Preventing Heat-Related Illness

Prevention Tips:

  • Drink more fluids (nonalcoholic), regardless of your activity level. Don’t wait until you’re thirsty to drink. Warning: If your doctor generally limits the amount of fluid you drink or has you on water pills, ask your doctor how much you should drink while the weather is hot.
  • Don’t drink liquids that contain alcohol or large amounts of sugar–these actually cause you to lose more body fluid. Also, avoid very cold drinks, because they can cause stomach cramps.
  • Stay indoors and, if at all possible, stay in an air-conditioned place. If your home does not have air conditioning, go to the shopping mall or public library–even a few hours spent in air conditioning can help your body stay cooler when you go back into the heat. Call your local health department to see if there are any heat-relief shelters in your area.
  • Electric fans may provide comfort, but when the temperature is in the high 90s, fans will not prevent heat-related illness. Taking a cool shower or bath, or moving to an air-conditioned place is a much better way to cool off.
  • Wear lightweight, light-colored, loose-fitting clothing.
  • NEVER leave anyone in a closed, parked vehicle.
  • Although any one at any time can suffer from heat-related illness, some people are at greater risk than others. Check regularly on:
    • Infants and young children
    • People aged 65 or older
    • People who have a mental illness
    • Those who are physically ill, especially with heart disease or high blood pressure
  • Visit adults at risk at least twice a day and closely watch them for signs of heat exhaustion or heat stroke. Infants and young children, of course, need much more frequent watching.

If you must be out in the heat:

  • Limit your outdoor activity to morning and evening hours.
  • Cut down on exercise. If you must exercise, drink two to four glasses of cool, nonalcoholic fluids each hour.  A sports beverage can replace the salt and minerals you lose in sweat. Warning: If you are on a low-salt diet, talk with your doctor before drinking a sports beverage. Remember the warning in the first “tip” (above), too.
  • Try to rest often in shady areas.
  • Protect yourself from the sun by wearing a wide-brimmed hat (also keeps you cooler) and sunglasses and by putting on sunscreen of SPF 15 or higher (the most effective products say “broad spectrum” or “UVA/UVB protection” on their labels).

Cold Weather Safety

Dress Warmly and Stay Dry

Adults and children should wear:

  • a hat
  • a scarf or knit mask to cover face and mouth
  • sleeves that are snug at the wrist
  • mittens (they are warmer than gloves)
  • water-resistant coat and boots
  • several layers of loose-fitting clothing

Be sure the outer layer of your clothing is tightly woven, preferably wind resistant, to reduce body-heat loss caused by wind. Wool, silk, or polypropylene inner layers of clothing will hold more body heat than cotton. Stay dry—wet clothing chills the body rapidly. Excess perspiration will increase heat loss, so remove extra layers of clothing whenever you feel too warm. Also, avoid getting gasoline or alcohol on your skin while de-icing and fueling your car or using a snow blower. These materials in contact with the skin greatly increase heat loss from the body. Do not ignore shivering. It’s an important first sign that the body is losing heat. Persistent shivering is a signal to return indoors.

Avoid Frostbite and Hypothermia

When exposed to cold temperatures, your body begins to lose heat faster than it can be produced. Prolonged exposure to cold will eventually use up your body’s stored energy. The result is hypothermia, or abnormally low body temperature. Body temperature that is too low affects the brain, making the victim unable to think clearly or move well. This makes hypothermia particularly dangerous because a person may not know it is happening and won’t be able to do anything about it.

Hypothermia is most likely at very cold temperatures, but it can occur even at cool temperatures (above 40°F) if a person becomes chilled from rain, sweat, or submersion in cold water.

Frostbite is an injury to the body that is caused by freezing. Frostbite causes a loss of feeling and color in affected areas. It most often affects the nose, ears, cheeks, chin, fingers, or toes. Frostbite can permanently damage the body, and severe cases can lead to amputation. The risk of frostbite is increased in people with reduced blood circulation and among people who are not dressed properly for extremely cold temperatures.

Understand Wind Chill

The Wind Chill index is the temperature your body feels when the air temperature is combined with the wind speed. It is based on the rate of heat loss from exposed skin caused by the effects of wind and cold. As the speed of the wind increases, it can carry heat away from your body much more quickly, causing skin temperature to drop. When there are high winds, serious weather-related health problems are more likely, even when temperatures are only cool.

The Wind Chill Chart below shows the difference between actual air temperature and perceived temperature, and amount of time until frostbite occurs.

Capture

What to Do if You Get Stranded

Staying in your vehicle when stranded is often the safest choice if winter storms create poor visibility or if roadways are ice covered. These steps will increase your safety when stranded:

  • Tie a brightly colored cloth to the antenna as a signal to rescuers and raise the hood of the car (if it is not snowing).
  • Move anything you need from the trunk into the passenger area.
  • Wrap your entire body, including your head, in extra clothing, blankets, or newspapers.
  • Stay awake. You will be less vulnerable to cold-related health problems.
  • Run the motor (and heater) for about 10 minutes per hour, opening one window slightly to let in air. Make sure that snow is not blocking the exhaust pipe—this will reduce the risk of carbon monoxide poisoning.
  • As you sit, keep moving your arms and legs to improve your circulation and stay warmer.
  • Do not eat unmelted snow because it will lower your body temperature.
  • Huddle with other people for warmth.

 

Stroke Alert Act F.A.S.T.

Warning Signs

  • Sudden numbness or weakness in the face, arm or leg, especially on one side of the body
  • Sudden confusion, trouble speaking or understanding
  • Sudden trouble seeing in one or both eyes
  • Sudden trouble walking, dizziness, loss of balance or coordination
  • Sudden, severe headache with no known cause

Act Quickly to Limit Permanent Damage – Use the F.A.S.T. Approach

Face

  • Ask the person to smile.
  • Does one side of the face droop?

Arms

  • Ask the person to raise both arms.
  • Does one arm drift downward?

Speech

  • Ask the person to repeat a simple sentence.
  • Are the words slurred? Can he/she repeat the sentence correctly?

Time

  • If the person shows any of these symptoms time is important.
  • Call 9-1-1 or get to the hospital fast. Brain cells are dying.

Effects of Stroke

The effects of a stroke depend on several factors, including the location of the obstruction and how much brain tissue is affected. However, because one side of the brain controls the opposite side of the body, a stroke affecting one side will result in neurological complications on the side of the body it affects.

Right Brain

If the stroke occurs in the right side of the brain, the left side of the body (and the right side of the face) will be affected, which could produce any or all of the following:

  • Paralysis on the left side of the body
  • Vision problems
  • Quick, inquisitive behavioral style
  • Memory loss

Left Brain

If the stroke occurs in the left side of the brain, the right side of the body will be affected, producing some or all of the following:

  • Paralysis on the right side of the body
  • Speech/language problems
  • Slow, cautious behavioral style
  • Memory loss

Heart Attack

Warning Signs

  • Chest discomfort. Most heart attacks come on slowly with discomfort in the center of the chest that can feel like uncomfortable pressure, squeezing, fullness or pain.
  • Discomfort in other areas of the upper body, such as the arms, back, neck, jaw or stomach.
  • Shortness of breath.
  • Cold sweat, nausea or lightheadedness

What to Do

  • Call for help. Calling 9-1-1 is almost always the fastest way to get lifesaving treatment. Emergency medical services staff can begin treatment when they arrive and are trained to revive someone whose heart has stopped. Patients who arrive by ambulance usually receive faster treatment at the hospital, too.
  • If you can’t access EMS, have someone drive you to the hospital right away. If you’re the one having symptoms, don’t drive yourself, unless you have absolutely no other option.

Cardiac Arrest

Warning Signs

  • Cardiac arrest strikes immediately and without warning.
  • Sudden loss of responsiveness. No response to gentle shaking.
  • No normal breathing. The victim does not take a normal breath when you check for several seconds.
  • No signs of circulation. No movement or coughing.

What to Do

  • Call 9-1-1 and begin CPR immediately.
  • If an automated external defibrillator (AED) is available and someone trained to use it is nearby, involve them.

Bike Helmets

A fall from a bike can be serious, especially if you hit your head. Wear a helmet to protect your head.

Step 1 – Size: Measure your head for approximate size. Try the helmet on to ensure it fits snuggly. While it is sitting flat on top of your head, make sure the helmet doesn’t rock side to side. Use sizing pads to ensure a proper fit.

Step 2 – Position: The helmet should sit level on your head and low on your forehead—one or two finger-widths above your eyebrow.

Step 3 – Side Straps: Adjust the slider on both straps to form a “V” shape under, and slightly in front of, the ears. Lock the slider if possible.

Step 4 – Chin Strap: Buckle your chin strap in the center. Tighten the strap until it is snug, so that no more than one or two fingers fit under the strap.

Step 5 – Final Fitting:

  • Open your mouth wide…big yawn! The helmet should pull down on the head. If not, tighten the chin strap.
  • Does your helmet rock back more than two fingers above the eyebrows? If so, unbuckle and shorten the front strap by moving the slider forward.
  • Does your helmet rock forward into your eyes? If so, unbuckle, tighten the back strap by moving the slider back toward the ear.
