Staying Safe and Healthy in Extreme Cold Temperatures

Coping with Frigid Temperatures and Staying Healthy

When the weather outside is frightful, with below-freezing temperatures, bitter winds, and feelings that it's so hard and it's cold here, it can really do a number on your mood - not to mention your body. Exposure to the extreme cold brings increased risks of dangerous conditions like hypothermia and frostbite. However, by understanding what exactly these dangerously low temperatures do to your body and knowing how to prepare properly, you can safely endure and overcome the winter season.

Understanding Wind Chill and How Cold Weather Feels Even Colder

We've all experienced those winter days when the air feels vastly colder than the actual thermometer temperature. This experience is formally known as "wind chill" - and it can cause the frigid air to affect your body even more intensely. Wind chill refers to how cold the air feels on your exposed skin owing to the combined effect of existing outside temperatures and wind speed.

For example, a day with an actual temperature of just below 32 Fahrenheit may feel equivalent to 10F or lower when wind chill from strong gusts is factored in. This makes your body rapidly lose heat, upping your susceptibility to hypothermia and frostbite.

How Hypothermia Impacts the Body

One of the most dangerous effects of extremely freezing temperatures is hypothermia. This occurs when the body loses heat faster than it can produce heat, causing your core body temperature to fall below 95F. Even mild cases require immediate treatment to prevent complications.

It's frighteningly easy for hypothermia to set in when you're exposed to bitter cold. At very low temperatures, your body has to work extra hard to maintain its vital internal heat. But harsh winds remove body heat from the skin before your body can replace it. Early symptoms include intense shivering, fatigue, loss of coordination, and confusion or slurred speech.

Frostbite: How Extreme Cold Damages Skin and Tissue

Frostbite is another severe condition that can result from flesh being exposed to the bitter cold. This most often impacts the fingers, toes, nose, ears, cheeks, and chin. Frostbite happens when skin and underlying tissues freeze from extended contact with extremely cold temperatures.

At first, frostbite causes tingling or stinging sensation. Then the skin turns red, pale, or white, going numb as ice crystals start to form. Continued freezing can permanently damage body tissue. Severe frostbite needs rapid medical help to avoid amputation.

Coping with Cold-Induced Respiratory Issues

Your respiratory system also suffers in subzero temperatures. Breathing in that biting air can induce coughing, wheezing, chest tightness, and worsened asthma in cold-sensitive people. The icy air also makes it easier to develop respiratory infections like bronchitis or pneumonia.

Managing Chronic Lung Diseases

For those living with chronic obstructive pulmonary disease (COPD) or other lung problems, extreme cold poses high risks. Low temperatures already make it harder to breathe. The additional strain can trap airway-clogging mucus and trigger dangerous COPD flare-ups or asthma attacks.

If you have respiratory issues, be vigilant about taking your maintenance inhalers or nebulizer medications as prescribed before facing icy conditions. Cover your nose and mouth with a mask or scarf outside. this warms the air slightly before inhaling. Also avoid sudden deep breaths of cold atmosphere that can send your sensitive airways into spasm.

The Impact of Dry Air on Respiratory Conditions

Not only are winter temperatures brutally cold - the air also becomes extremely dry. This very low humidity further aggravates coughing and breathing difficulties. The dry air literally dehydrates your lung tissues, diminishing their defenses against respiratory infections.

Try using an air humidifier indoors to help ease a parched, irritated respiratory tract. Also drink plenty of fluids to keep your secretions thin instead of thick and choking.

Avoiding Pain and Problems from Raynauds Syndrome

People who have the circulation disorder Raynaud's phenomenon face intensified risks when temperatures plummet. This condition causes the small arteries in the skin to suddenly constrict when you're chilled or stressed. Blood can't reach the skin well, causing numbness and a bloodless pale color in the fingers, toes, tip of the nose, and ears.

Managing Raynaud's Flare-Ups

To reduce Raynaud's flare-ups in winter: Bundle up warmly when going out, wearing gloves, insulated boots, a hat, scarf and thick insulating socks. Go indoors periodically to warm up. Limit caffeine and quit smoking, as these worsen Raynaud's. Try relaxation techniques to reduce flare triggers from emotional stress.

If you develop painful Raynaud's symptoms, get indoors and warm your hands with skin-to-skin contact. Run them under warm (not hot) water. Gently exercise your fingers to stimulate blood flow. See a doctor promptly for treatment if symptoms seem severe or last beyond warming up.

When to Seek Emergency Care

On very rare occasions, a Raynaud's attack affects blood flow so severely that tissue becomes damaged from the lack of oxygen and nutrients. Seek emergency care promptly if your fingers or toes turn blue or become numb and icy cold with a "pins and needles" sensation for more than a few minutes after you warm them up.

Quick medical attention is crucial anytime frostbite develops. That drastic skin color change warns that ice crystals are forming and actually freezing your delicate skin cells and nerve endings. Don't try to warm the area yourself with hot water or radiant heat, as this can actually worsen the tissue damage.

The Importance of Dressing Warmly and Staying Dry

Clearly, exposure to extreme wintry temperatures delivers a major shock to nearly every system of your body. The key is knowing how to protect yourself appropriately when the weather outside seems almost unbearable.

Choosing Clothing for Maximum Warmth

The best way to arm yourself against the elements is wearing multiple loose layers of clothing for insulation. Thermal underwear and middle layers made of wool or fleece provide outstanding protection. Your outermost layer should block wind and repel moisture.

Cover up as much exposed skin as possible when outdoors. Be sure to wear insulated waterproof boots, gloves, and headwear. Take spares in case gloves get wet. Choose socks designed to wick moisture away from your feet.

Avoiding Exposure and Managing Necessary Outdoor Time

When temperatures start approaching dangerous extremes, it's wise to simply stay indoors if possible. If you must do outdoor tasks, take frequent warming breaks inside. Also, pay attention to your extremities like fingers and toes - numb or painful skin means it's time to get back inside immediately.

Drink warm fluids like caffeine-free herbal tea to maintain core body heat. Never drink alcohol before extended exposure in extreme cold, as it causes widening of blood vessels near skin and can hasten hypothermia.

Check weather forecasts and wind chill readings before venturing out so you can dress accordingly. Be extra cautious if needing to drive, as frostbite can begin faster than you might think if stuck outdoors after an accident.

Ultimately the healthiest plan is to be safely inside, nice and cozy, when the weather outside seems unbearable. Curl up under a blanket, sip some hot chocolate or apple cider, and wait for warmer days ahead!
