Winter storms are a defining part of life in Des Moines, Iowa. Residents are accustomed to snow-covered streets, icy sidewalks, freezing temperatures, and powerful winter systems that can disrupt daily life for days at a time. While these storms create beautiful winter landscapes, they also introduce serious health hazards that affect people of all ages. From cardiovascular emergencies caused by snow shoveling to dangerous carbon monoxide poisoning, winter weather presents medical risks that deserve careful attention.

Understanding these dangers allows individuals and families to prepare properly before storms arrive. Preventive measures, recognizing early warning signs, and knowing when to seek medical care can dramatically reduce injuries and save lives. Whether you're a lifelong Iowa resident or experiencing your first Midwest winter, understanding the health risks associated with severe winter weather is essential.

Why Winter Storms Present Serious Health Risks

Winter weather affects the human body in multiple ways. Cold temperatures force the cardiovascular system to work harder to maintain body heat. Ice increases the likelihood of falls and traumatic injuries. Heavy snowfall demands strenuous physical labor, while extended power outages can create unsafe indoor heating conditions.

Des Moines frequently experiences winter conditions that include:

• Heavy snowfall
• Ice accumulation
• Wind chills well below zero
• Blowing snow that limits visibility
• Prolonged freezing temperatures
• Road closures and transportation delays

These conditions increase emergency room visits every winter for weather-related illnesses and injuries.

Heart Attack Risk From Snow Shoveling

One of the most overlooked dangers during Iowa winters is the cardiovascular strain caused by snow shoveling.

Snow removal is surprisingly demanding. Lifting heavy, wet snow repeatedly raises heart rate, blood pressure, and oxygen demand all at once. Cold air causes blood vessels to constrict, making the heart work even harder.

The combination of physical exertion and freezing temperatures can trigger heart attacks, especially among people with:

• High blood pressure
• Coronary artery disease
• Previous heart attack
• Diabetes
• High cholesterol
• Obesity
• Smoking history
• Sedentary lifestyle

Many people underestimate how physically intense shoveling can be because it feels like a household chore rather than exercise.

If you have a heart condition, check the Des Moines winter storm warning today before deciding whether to shovel—during an active warning, heavy wet snow combined with cold air significantly increases cardiac risk.

Warning Signs of a Heart Attack While Shoveling

Stop immediately and call emergency services if you experience:

• Chest pressure
• Chest pain
• Pain spreading into the arm
• Jaw discomfort
• Back pain
• Shortness of breath
• Sudden nausea
• Cold sweating
• Extreme fatigue
• Dizziness

Never attempt to "push through" chest discomfort.

Minutes matter during a heart attack.

Safer Snow Removal Practices

Reduce cardiovascular risk by following several safety practices.

Warm up indoors for a few minutes before going outside.

Dress in breathable layers rather than one heavy coat.

Push snow whenever possible instead of lifting it.

Lift small amounts at a time.

Take frequent breaks.

Stay hydrated even though temperatures are cold.

Avoid shoveling immediately after waking up.

Never shovel after drinking alcohol.

Older adults and anyone with known heart disease should consider hiring snow removal services instead of performing heavy labor themselves.

Understanding Hypothermia

Hypothermia occurs when body temperature falls below 95°F (35°C).

Because Des Moines often experiences dangerous wind chills, hypothermia can develop surprisingly quickly, particularly during snowstorms accompanied by strong winds.

Children and older adults are especially vulnerable because their bodies regulate temperature less efficiently.

Individuals experiencing homelessness and those stranded in vehicles are also at elevated risk.

Early Symptoms

Early hypothermia often develops gradually.

Common warning signs include:

• Continuous shivering
• Numb fingers
• Difficulty speaking clearly
• Confusion
• Fatigue
• Poor coordination
• Clumsiness
• Slowed thinking

As hypothermia worsens, shivering may stop completely, which is actually a dangerous sign rather than an improvement.

Severe Hypothermia Symptoms

Advanced hypothermia can cause:

• Slurred speech
• Slow pulse
• Slow breathing
• Loss of consciousness
• Dilated pupils
• Inability to walk
• Severe confusion
• Cardiac arrest

Immediate emergency medical treatment is required.

Treating Hypothermia Safely

If someone appears hypothermic:

Move them indoors immediately.

Remove wet clothing carefully.

Replace wet garments with dry, insulated clothing.

Wrap the person in blankets.

Warm the body's core before warming hands or feet.

Offer warm beverages only if the person is fully conscious.

Avoid alcohol and caffeine.

Never place someone into extremely hot water or use direct high heat such as heating pads against bare skin.

Rapid external heating can cause dangerous cardiovascular complications.

Call emergency medical services whenever moderate or severe hypothermia is suspected.

Frostbite: Permanent Damage Can Occur Quickly

Frostbite develops when skin and underlying tissue freeze.

The ears, nose, cheeks, fingers, and toes are most commonly affected.

Wind dramatically increases frostbite risk even if air temperatures alone seem manageable.

Early Frostbite Symptoms

Initial symptoms include:

• Tingling
• Burning sensation
• Pale skin
• Waxy appearance
• Numbness
• Firm skin texture

Without intervention, frostbite progresses deeper into tissue.

Severe Frostbite

Advanced frostbite may cause:

• Skin turning white or gray
• Hard frozen tissue
• Blisters after rewarming
• Blackened tissue
• Permanent nerve damage
• Tissue death

Severe frostbite may ultimately require surgical treatment.

Proper Frostbite Treatment

Get indoors immediately.

Protect affected areas from further cold exposure.

Do not rub frozen skin.

Do not massage affected tissue.

Do not use snow to warm frozen skin.

Rewarm using warm (not hot) water between approximately 98°F and 104°F if medical care is not immediately available.

Protect the area with clean dressings.

Seek emergency medical evaluation if blisters develop or sensation does not return.

Carbon Monoxide Poisoning During Winter Storms

Power outages are common during severe winter storms.

When electricity fails, people often rely on portable generators, propane heaters, fireplaces, or charcoal grills for warmth.

Improper use creates one of winter's deadliest hazards: carbon monoxide poisoning.

Carbon monoxide is:

• Colorless
• Odorless
• Tasteless
• Invisible

People often become unconscious before realizing they have been exposed.

Common Sources

Potential carbon monoxide sources include:

Portable generators

Vehicles left running inside attached garages

Gas-powered pressure washers

Charcoal grills

Blocked furnace exhaust systems

Snow-covered furnace vents

Gas fireplaces

Portable fuel heaters

Blocked chimneys

Snow accumulation around exterior vents is particularly dangerous because combustion gases cannot escape properly.

Carbon Monoxide Poisoning Symptoms

Symptoms often resemble influenza.

Early warning signs include:

• Headache
• Dizziness
• Weakness
• Nausea
• Vomiting
• Confusion
• Fatigue

Higher exposure causes:

• Collapse
• Seizures
• Unconsciousness
• Cardiac complications
• Death

Entire households may become ill simultaneously.

That is an important clue suggesting carbon monoxide exposure rather than viral illness.

Prevention Strategies

Install carbon monoxide detectors on every level of the home.

Test detectors before winter begins.

Never operate generators inside garages.

Keep generators at least twenty feet away from windows and doors whenever possible.

Keep furnace vents free of snow.

Inspect chimneys annually.

Never heat a home with charcoal grills.

If a detector alarms:

Leave immediately.

Call emergency services.

Do not re-enter until professionals determine it is safe.

Seasonal Affective Disorder During Long Winter Storms

Winter affects mental health as well as physical health.

Seasonal Affective Disorder (SAD) is a form of depression associated with reduced daylight exposure.

In Des Moines, prolonged cloudy conditions combined with repeated winter storms may worsen symptoms.

People may spend several consecutive days indoors because of hazardous road conditions.

Reduced sunlight affects the body's circadian rhythm and influences serotonin and melatonin production.

Symptoms of Seasonal Affective Disorder

Individuals experiencing SAD may notice:

• Persistent sadness
• Low motivation
• Sleeping more than usual
• Difficulty concentrating
• Loss of interest in activities
• Increased appetite
• Weight gain
• Social withdrawal
• Irritability

Symptoms usually improve as daylight increases in spring.

Managing Mental Health During Winter

Maintain a consistent daily schedule.

Open curtains during daylight hours.

Exercise indoors when outdoor conditions are unsafe.

Stay socially connected through phone or video calls.

Eat balanced meals.

Limit alcohol consumption.

Some individuals benefit from medically recommended light therapy.

Anyone experiencing persistent depression or thoughts of self-harm should seek immediate professional mental health assistance.

Pharmacy Access During Winter Road Closures

Major snowstorms sometimes make travel unsafe throughout central Iowa.

Road closures, drifting snow, and icy conditions may prevent residents from reaching pharmacies.

Prescription interruptions can become medical emergencies.

This is especially true for medications involving:

• Insulin
• Heart disease
• Blood pressure
• Asthma
• COPD
• Seizure disorders
• Blood thinners
• Mental health treatment

Running out of medication during a prolonged storm increases hospitalization risk.

Preparing Before Winter Storms

Residents should maintain:

A one- to two-week medication supply whenever possible.

Updated medication lists.

Copies of prescriptions.

Emergency contact information.

Backup medical equipment batteries.

Individuals using oxygen concentrators or electrically powered medical devices should discuss emergency planning with healthcare providers before winter arrives.

Many pharmacies offer prescription synchronization and automatic refills, reducing the chance of running out before major storms.

Mail-order services can also improve medication access during winter.

Medical Equipment During Power Outages

Power outages create additional challenges for patients who depend on:

• CPAP machines
• Oxygen concentrators
• Home dialysis equipment
• Refrigerated medications
• Mobility devices
• Feeding pumps

Families should develop emergency backup plans well before severe weather begins.

Battery backups, generators installed according to safety standards, and coordination with utility companies can reduce risk.

Hospital Emergency Preparedness in Des Moines

Hospitals throughout the Des Moines metropolitan area prepare extensively before significant winter storms.

Emergency preparedness planning generally includes:

Additional staffing before storms arrive.

Emergency fuel supplies for backup generators.

Expanded emergency department capacity.

Coordination with ambulance services.

Communication with public health agencies.

Stockpiling medications and medical supplies.

Snow removal planning for hospital entrances.

Maintaining emergency power for critical equipment.

Hospitals also coordinate with emergency management agencies to prioritize access routes for ambulances during heavy snowfall.

Emergency Departments During Winter Storms

Falls on ice

Motor vehicle crashes

Hypothermia

Frostbite

Carbon monoxide poisoning

Heart attacks

Respiratory illnesses

Snowblower injuries

Lacerations

Broken bones

Healthcare providers encourage residents to seek immediate emergency care for life-threatening conditions even during severe weather.

Emergency medical services remain available despite challenging road conditions.

Falls and Ice Injuries

Although cold exposure receives significant attention, slips and falls remain among the most common winter injuries.

Ice-covered sidewalks and parking lots can lead to:

• Hip fractures
• Wrist fractures
• Concussions
• Shoulder injuries
• Spinal injuries
• Facial trauma

Older adults face particularly high risks because falls frequently result in hospitalization.

Wearing footwear with good traction and walking carefully can significantly reduce injury risk.

Children and Winter Health

Children lose body heat faster than adults.

Parents should monitor outdoor play closely.

Watch for:

• Wet gloves
• Wet boots
• Red cheeks
• Complaints of numb fingers
• Excessive shivering

Children should come indoors regularly to warm up.

Adequate hydration remains important even during cold weather.

Protecting Older Adults

Older adults often experience reduced circulation and diminished awareness of cold exposure.

Families should regularly check on elderly relatives during severe weather.

Ensure homes remain adequately heated.

Verify medications are available.

Confirm working smoke and carbon monoxide detectors.

Encourage avoiding outdoor activities during extreme cold whenever possible.

Preparing a Winter Health Emergency Kit

Every household should maintain a winter emergency health kit containing:

• Prescription medications
• First aid supplies
• Flashlights
• Extra batteries
• Bottled water
• Shelf-stable food
• Warm blankets
• Hand warmers
• Thermometer
• Battery-powered weather radio
• Phone chargers
• Medical information cards
• Carbon monoxide detector batteries

Preparation before a storm reduces stress when severe weather arrives unexpectedly.
