Winter storms in Missoula, Montana, can transform an ordinary day into a serious health and safety challenge. Heavy snow, freezing temperatures, icy roads, power outages, blocked transportation routes, and prolonged periods indoors can affect nearly every aspect of personal health. While winter weather is often associated with slips and falls, the risks extend much further. Cardiovascular emergencies, hypothermia, frostbite, carbon monoxide poisoning, mental-health difficulties, medication interruptions, and pressure on emergency medical services can all become more likely when a major storm disrupts normal routines.

Missoula residents can reduce many of these dangers by preparing before a storm arrives and recognizing the warning signs of medical emergencies. A useful first step is monitoring weather conditions before heading outdoors. For example, residents with cardiovascular conditions should check the Missoula winter storm warning today before deciding whether to shovel or travel, particularly when heavy snow and freezing temperatures are expected.

The following health risks deserve special attention during major winter storms.

Snow Shoveling Can Increase Heart Attack Risk

Snow removal may seem like routine household work, but shoveling can be strenuous exercise. During winter storms, the combination of physical exertion, cold temperatures, heavy snow, and stress can place additional demands on the cardiovascular system.

Cold weather causes blood vessels to constrict, which can increase blood pressure. At the same time, shoveling requires repetitive lifting and pushing. Heavy or wet snow can be particularly demanding. The body must also work harder to maintain its core temperature in cold conditions. According to the CDC, cold weather places additional strain on the heart, and people with heart disease or high blood pressure should follow their healthcare provider's advice regarding strenuous outdoor work.

People at greater cardiovascular risk should consider alternatives to personally shoveling, such as asking family members, neighbors, or a professional snow-removal service for assistance. This is especially important for older adults and people with known heart disease, high blood pressure, diabetes, obesity, or a history of stroke.

If shoveling is necessary, avoid trying to clear the entire driveway quickly. Work slowly, take frequent breaks, dress in layers, and avoid becoming soaked with sweat. Wet clothing loses insulating ability and can accelerate heat loss.

Most importantly, recognize the symptoms of a possible heart attack. Chest pressure, squeezing, or pain; pain spreading to the arm, shoulder, back, neck, or jaw; unusual shortness of breath; cold sweating; nausea; or sudden weakness should not be dismissed as simple exhaustion.

If these symptoms occur, stop working and seek emergency medical assistance immediately. Do not attempt to "push through" symptoms because the storm makes medical care inconvenient.

Hypothermia Can Develop Before People Realize They Are in Danger

Hypothermia occurs when the body loses heat faster than it can produce it. Although the risk is greatest in extremely cold environments, hypothermia can also occur in less severe temperatures when someone is wet, exhausted, inadequately dressed, or exposed for a prolonged period.

This makes hypothermia particularly relevant during Missoula winter storms. Someone clearing snow, walking to a vehicle, waiting for roadside assistance, or dealing with a heating failure can gradually become dangerously cold.

Early warning signs include:

• Shivering
• Fatigue or unusual tiredness
• Clumsiness
• Difficulty concentrating
• Fumbling with objects
• Confusion
• Slurred speech
• Drowsiness

As hypothermia becomes more severe, a person's judgment and coordination can deteriorate. In advanced cases, shivering may stop, consciousness can be lost, and breathing and heart rate can slow.

A body temperature below 95°F is considered a medical emergency when hypothermia is suspected.

If someone shows signs of hypothermia, move them into a warm, dry environment. Remove wet clothing and replace it with dry layers or blankets. Focus on warming the body's core, particularly the chest, neck, head, and groin. If the person is awake and able to swallow safely, warm nonalcoholic beverages can help.

Never give fluids to an unconscious person, and never use alcohol as a warming method.

Severe hypothermia requires emergency medical care. Handle a severely hypothermic person gently and call 911.

Frostbite Requires Prompt and Careful Treatment

Frostbite happens when skin and underlying tissues freeze. Fingers, toes, ears, nose, cheeks, and chin are particularly vulnerable because these areas are exposed and have less protection from the cold.

Early frostbite may cause redness, pain, tingling, or numbness. More developed frostbite can cause skin to become white, grayish-yellow, unusually firm, or waxy. Numbness can make the injury difficult for the affected person to recognize.

The first priority is getting out of the cold. Move indoors or into another warm shelter and protect the affected area from additional exposure.

If immediate medical care is unavailable and there are no signs of hypothermia, frostbitten tissue can be gently rewarmed in warm, not hot, water. The water should feel comfortably warm to unaffected skin.

There are several important things not to do.

Do not rub frostbitten skin. Do not massage it. Do not rub it with snow. Avoid heating pads, heat lamps, fireplaces, radiators, or other intense direct heat because numb tissue can burn easily.

If the feet or toes are frostbitten, avoid walking on them unless absolutely necessary because walking can increase tissue damage. Frostbite should be evaluated by a healthcare professional because serious injuries can cause permanent tissue damage.

Carbon Monoxide Is a Major Winter Storm Hazard

Power outages create another dangerous situation. When electricity fails, households may turn to portable generators, propane equipment, fireplaces, wood-burning appliances, or other alternative heating sources.

Improper use can result in carbon monoxide poisoning.

Carbon monoxide, commonly called CO, is a colorless and odorless gas. It can cause sudden illness and death, and people may not realize they are being exposed. Common symptoms include headache, dizziness, weakness, nausea, vomiting, chest pain, and confusion.

Portable generators are particularly important to use correctly.

A generator should never be operated inside a house, basement, garage, shed, or other enclosed or partially enclosed space. The CDC recommends placing portable generators more than 20 feet from windows, doors, and vents.

Opening a garage door is not an adequate safety measure. Carbon monoxide can accumulate even when an area appears to have ventilation.

Every home using fuel-burning equipment should have working carbon monoxide detectors. Battery-powered or battery-backup detectors are particularly important during power outages.

Blocked Vents and Chimneys Can Also Cause CO Poisoning

Generators are not the only concern. Snow and ice can block furnace exhaust vents, chimneys, or other ventilation systems.

Before and during a major storm, residents should make sure outdoor vents remain clear. After significant snowfall, check areas around furnace vents, dryer vents, water-heater vents, and chimneys when it is safe to do so.

Do not climb onto a snow-covered roof simply to inspect a vent during dangerous weather. If an exhaust system is difficult to access safely, contact a qualified professional.

The same principle applies to vehicles. Never run a vehicle inside a garage, even if the garage door is open. If a vehicle becomes stranded during a storm, make sure its exhaust pipe remains clear of snow before running the engine. The CDC specifically warns that a blocked exhaust pipe can allow deadly carbon monoxide to enter the passenger compartment.

If multiple people in a household suddenly develop headaches, dizziness, nausea, weakness, or confusion, consider carbon monoxide exposure as a possibility. Leave the building for fresh air and seek emergency assistance rather than remaining inside to investigate.

Prolonged Storms Can Affect Mental Health

Winter storms do not only affect physical health. Extended periods of darkness, isolation, canceled activities, travel restrictions, and reduced exposure to daylight can affect mood and emotional well-being.

Some people experience seasonal affective disorder, commonly known as SAD, a form of depression associated with seasonal changes. Prolonged severe weather can also aggravate feelings of loneliness, stress, anxiety, frustration, or helplessness, even in people who do not have SAD.

Being confined indoors for several days can disrupt normal sleep schedules, physical activity, work routines, and social interaction. For households already dealing with financial stress, illness, caregiving responsibilities, or other challenges, a major winter storm can intensify those pressures.

Maintaining a basic routine can help. Try to wake and sleep at consistent times, eat regular meals, remain physically active indoors when possible, and seek natural daylight during safe periods. Staying connected with friends, relatives, and neighbors through phone calls or online communication can also reduce isolation.

People experiencing persistent depression, hopelessness, severe anxiety, or thoughts of self-harm should seek professional help rather than assuming the feelings will disappear when the weather improves. In an immediate crisis, call 911 or use an appropriate crisis service.

Medication Access Can Become Difficult During Road Closures

Prescription medication is another concern that is easy to overlook when preparing for winter storms.

A person may have enough food and heating supplies but still face a medical problem if an essential prescription runs out while roads are unsafe. Road closures, reduced pharmacy hours, transportation problems, and delivery delays can make medication access more difficult.

Residents who rely on daily medications should check their supplies before severe weather arrives. Where appropriate, ask a healthcare provider or pharmacist about refills in advance. People should not simply stop prescription medications because they cannot reach a pharmacy without first seeking medical guidance.

This is especially important for medications used to manage conditions such as epilepsy, diabetes, heart disease, asthma, severe allergies, or other conditions where missed doses can create serious complications.

Keep a current medication list that includes prescription names, doses, prescribing providers, and pharmacy information. Store medications according to their required conditions, especially during power outages.

Patients who use refrigerated medications should also have a storm plan. Ask their pharmacist or healthcare provider ahead of time about appropriate storage during an extended power failure.

Do not assume that a pharmacy is open simply because roads in your neighborhood appear passable. Storm-related staffing, power failures, transportation disruptions, and local conditions can change operating schedules.

Hospitals Must Prepare for Multiple Emergencies at Once

Winter storms can create unusual pressure on hospitals and emergency medical systems.

Healthcare facilities may need to manage patients suffering from hypothermia, frostbite, falls, vehicle crashes, cardiac events, respiratory problems, and carbon monoxide poisoning while simultaneously dealing with transportation disruptions and potential power outages.

Hospitals generally have emergency preparedness plans designed to maintain critical operations during severe weather. Backup power systems, emergency communications, staffing plans, supply reserves, transportation arrangements, and coordination with local emergency agencies can all become important during a major storm.

However, residents should not assume that hospitals operate normally under every weather condition. Ambulances can face longer travel times when roads are hazardous, and emergency departments may experience unusually high patient volumes.

This makes personal preparation particularly valuable.

Residents with serious medical conditions should know where they normally receive emergency care and have important medical information readily available. Keep identification, medication lists, insurance information, and essential medical documents accessible in case an emergency evacuation or hospital visit becomes necessary.

People who require regular medical treatments, such as dialysis or other time-sensitive therapies, should discuss winter-weather contingency plans with their healthcare providers before storm season.

Older Adults and Children Need Extra Attention

Certain groups are more vulnerable to cold-related illness.

Older adults may have difficulty maintaining body temperature and may live alone or have limited mobility. Babies and young children can also lose body heat quickly.

During prolonged storms, check on vulnerable family members and neighbors when it can be done safely. A simple phone call can identify problems with heating, food, medications, or mobility before they become emergencies.

Children should also be supervised around snow, ice, heaters, fireplaces, and generators. They may not recognize the early signs of cold injury or understand why certain equipment is dangerous.

Pets require attention as well. Animals can develop cold-related injuries, and indoor pets should never be left in unheated environments for extended periods.

Preparing a Winter Health Kit Before the Storm

A storm-ready health kit can make a significant difference if roads become impassable.

Consider keeping the following supplies available:

• At least several days of essential medications
• A written medication and medical-condition list
• First-aid supplies
• Thermometer
• Battery-powered or battery-backup carbon monoxide detector
• Flashlights and extra batteries
• Warm blankets and sleeping bags
• Extra warm clothing
• Nonperishable food and safe drinking water
• Phone chargers or backup power banks
• Basic hygiene supplies
• Emergency contact information
• Necessary medical equipment and backup supplies

Households should also know where their nearest appropriate medical facilities are and understand when a condition requires immediate emergency assistance.

Know When to Stay Home and When to Seek Help

One of the most important decisions during a winter storm is determining whether a medical problem can safely wait.

Minor illnesses may sometimes be managed at home, but potentially life-threatening symptoms should never be ignored because roads are snowy.

Seek emergency help for symptoms such as severe chest pain, significant difficulty breathing, loss of consciousness, severe confusion, signs of stroke, severe carbon monoxide exposure, or advanced hypothermia.

Likewise, serious frostbite requires medical evaluation, particularly when tissue is deeply numb, discolored, hard, blistered, or extensively affected.

If emergency services are needed, tell the dispatcher about the weather conditions and any known road-access problems. Do not attempt a dangerous drive yourself if emergency transportation is the safer option.

Winter Storm Health Preparation Is About Prevention

Winter storms in Missoula can create a chain reaction of health hazards. Snow shoveling can become strenuous cardiovascular exercise. Cold exposure can progress from uncomfortable shivering to life-threatening hypothermia. Frostbite can permanently damage tissue. Poorly positioned generators and blocked vents can fill a home with carbon monoxide. Isolation and reduced daylight can affect mental health. Road closures can interfere with prescriptions and medical appointments, while hospitals and emergency responders may face increased demand.

The best strategy is to prepare before conditions deteriorate.

Know your personal medical risks. Keep medications and essential supplies available. Install working carbon monoxide detectors. Keep vents and exhaust systems clear. Avoid unnecessary outdoor exposure during dangerous conditions. Do not treat heavy snow removal as a harmless household chore if you have cardiovascular risk factors. Check on vulnerable neighbors and relatives, and know the warning signs that require emergency care.

Most importantly, remember that winter storm safety is not simply about staying warm. It is about protecting the heart, brain, lungs, skin, mental health, and access to essential medical care throughout the entire storm. A few hours of preparation before severe weather arrives can prevent a medical emergency when roads are icy, temperatures are falling, and normal services are disrupted
