Winter storms in Nashua, New Hampshire, can create much more than inconvenience. Heavy snow, freezing temperatures, strong winds, icy roads, power outages, and blocked travel routes can create a combination of health hazards that affect the heart, lungs, skin, mental health, and access to essential medical care. A storm can also turn routine activities such as shoveling a driveway, walking to a vehicle, or running a portable heater into potentially dangerous situations.

Nashua residents should take particular care during prolonged winter events because cold exposure can become dangerous when people remain outdoors too long or lose access to reliable heat. The City of Nashua specifically identifies hypothermia and frostbite as important winter health concerns and recommends preparing homes, monitoring weather warnings, keeping emergency supplies available, and maintaining working carbon monoxide detectors with battery backups.

Knowing the warning signs of cold-related illness and understanding when an activity is too risky can make a significant difference. If you have a heart condition, check the Nashua winter storm warning today before deciding whether to shovel or travel. The following guide explains the major health risks Nashua residents should consider before, during, and after a winter storm.

Snow Shoveling and the Risk of Heart Attack

Snow shoveling can be strenuous exercise, particularly when snow is deep, wet, or packed down. Cold temperatures add another physical burden because the body works harder to maintain its core temperature. For people with cardiovascular disease, high blood pressure, or limited exercise tolerance, suddenly performing heavy outdoor work can place significant stress on the heart.

The combination of cold air and physical exertion can increase the workload on the cardiovascular system. The City of Nashua specifically identifies people with heart disease or high blood pressure, as well as people who overexert themselves, among those who need particular caution around cold-weather health risks.

People who are not accustomed to regular strenuous exercise may be especially vulnerable when they attempt to clear an entire driveway or sidewalk quickly. Pushing a heavy shovel, lifting wet snow, repeatedly bending down, and working against wind can produce intense exertion within a short period.

Anyone with known heart disease should follow their healthcare professional's advice about snow removal. Depending on a person's medical history, asking another household member, neighbor, or professional service to handle heavy snow may be safer than doing it personally.

Recognize Heart Attack Warning Signs

A heart attack does not always begin with dramatic or crushing chest pain. Warning signs can include pressure or discomfort in the chest, pain in the arms, back, shoulders, neck, or jaw, shortness of breath, sweating, nausea, dizziness, unusual fatigue, or an unusually rapid or irregular heartbeat. Symptoms can vary between individuals.

If these symptoms occur while shoveling or shortly afterward, stop the activity immediately. Do not assume that discomfort is simply caused by physical exertion or cold weather. If a heart attack is suspected, call 911 rather than attempting to drive yourself to a hospital. Emergency medical personnel can begin assessment and treatment while transporting the patient.

Hypothermia During Nashua Winter Storms

Hypothermia happens when the body loses heat faster than it can produce it. It is often associated with very cold weather, but it can also develop in cooler conditions when someone becomes wet from snow, rain, sweat, or cold water. This makes hypothermia a concern during long periods of outdoor work, vehicle problems, power outages, or inadequate home heating.

According to the CDC, early warning signs in adults include shivering, exhaustion, confusion, fumbling hands, memory problems, slurred speech, and drowsiness. A body temperature below 95°F is an emergency requiring immediate medical attention.

One reason hypothermia is particularly dangerous is that it can interfere with judgment and coordination. A person may become confused and fail to recognize how serious the situation has become. Someone who is beginning to experience hypothermia may also have difficulty walking, communicating, or getting themselves to a warm location.

Who Is Most Vulnerable?

Older adults, infants, people who spend extended periods outdoors, and people without adequate heating, food, or warm clothing can face increased risk. Alcohol use can also increase vulnerability to cold-related illness.

During a prolonged storm, Nashua households should check on older relatives, neighbors who live alone, and anyone who may have difficulty maintaining a warm indoor environment. The city also recommends checking frequently on older family members, friends, and neighbors during extreme cold.
