Living in a cold house can have a significant impact on your health. While you may think it’s only uncomfortable, exposure to cold indoor temperatures can cause both short-term and long-term effects on your body. Many people in the U.S. struggle with poorly insulated homes, especially during the winter months. It’s crucial to understand the risks and how to protect yourself from the adverse effects of living in a cold house.
Here, we will discuss what happens to your body when you live in a cold house, the risks associated with prolonged exposure to low temperatures, and how you can stay safe and healthy in colder indoor environments.
How Cold House Affects Your Body
When your home is colder than your body’s ideal temperature (around 68–72°F), your body has to work harder to maintain warmth. This can lead to several problems, including:
1. Increased Stress on the Cardiovascular System
Cold temperatures cause blood vessels to constrict. When blood vessels constrict, your heart has to pump harder to circulate blood throughout the body. This can cause a rise in blood pressure, increasing the risk of heart attack, stroke, and other cardiovascular issues, especially for individuals with pre-existing heart conditions.
2. Risk of Hypothermia
Hypothermia is diagnosed when the body temperature drops below 95°F. It can happen if you stay in an environment that is too cold for extended periods. In a cold house, especially one that is not heated properly, hypothermia is a real risk. Common signs of hypothermia are shivering, confusion, difficulty speaking, and, in severe cases, loss of consciousness. Hypothermia is more common among vulnerable populations such as the elderly, children, and people with chronic illnesses.
3. Weakened Immune System
Cold weather can suppress your immune system. Your body focuses its energy on staying warm, which can reduce the effectiveness of your immune system responses. This makes you more susceptible to illnesses like colds, flu, and respiratory infections. In addition, exposure to cold can dry out the mucous membranes in your nose, which act as a barrier against viruses.
4. Joint Pain and Muscle Stiffness
Cold environments can make your muscles and joints stiffen. When you are exposed to cold temperatures, your muscles contract in an attempt to generate heat. This can lead to joint pain, muscle cramps, and increased discomfort, particularly in people who suffer from conditions like arthritis. If your home is cold and you don’t move around much, these symptoms may increase over time.
5. Poor Sleep Quality
A cold house can affect your sleep quality. While some people believe they sleep better in cold environments, extremely low temperatures can disrupt your sleep. When your body is too cold, it struggles to reach a comfortable sleep state, causing frequent awakenings, restlessness, and difficulty falling asleep. Inadequate sleep can further affect your health, leading to fatigue, difficulty while concentrating, and weakened immunity.
6. Mental Health Strain
Living in a cold environment can also affect your mental health. When your body is constantly fighting to stay warm, it can lead to increased stress levels. Cold weather can trigger feelings of isolation, sadness, and even depression, especially if you have to stay indoors for long periods due to the cold. Additionally, reduced daylight hours in colder seasons can cause seasonal affective disorder (SAD), a type of depression related to changes in the seasons.
7. Risk of Frostbite
Frostbite occurs when skin and underlying tissue freeze, which is most common in extremely cold outdoor environments. However, when living in a cold house, frostbite can develop in extremities like fingers, toes, and ears, especially if you’re not dressed warmly enough. Symptoms of frostbite include numbness, skin discoloration, and a feeling of coldness in the affected areas.
Long-Term Health Risks
Long-term living in a cold house can potentially cause chronic health problems:
1. Respiratory Issues
Cold indoor air can worsen pre-existing respiratory conditions such as asthma, bronchitis, and COPD (chronic obstructive pulmonary disease). Breathing in cold air constricts the airways, which can trigger coughing, wheezing, and difficulty breathing. People with respiratory conditions should take extra precautions to avoid prolonged exposure to cold indoor temperatures.
2. Increased Risk of Cardiovascular Disease
As mentioned earlier, cold temperatures put extra stress on your cardiovascular system. Over time, living in a cold house can contribute to the development of high blood pressure and an increased risk of heart disease. Cold-induced stress can also contribute to other health conditions like arrhythmias (irregular heartbeats), which can be dangerous.
3. Reduced Mobility
Living in a cold house can reduce physical activity. People tend to move less in a cold environment, especially when their homes aren’t properly heated. A sedentary lifestyle leads to weight gain, muscle atrophy, and poor circulation. Over time, this can lead to long-term health problems like obesity, diabetes, and joint pain.
How to Stay Safe in a Cold House
While living in a cold house can be harmful to your health, there are steps you can do to reduce the impact of low temperatures:
1. Dress Warmly
Layer your clothes to capture heat and keep comfortable. Wear thermal socks, sweaters, and caps to help control your body temperature. Avoid wearing clothing that restricts blood flow, as this can lead to poor circulation. Thermal clothing and blankets can be an affordable approach to increasing warmth.
2. Use Space Heaters Wisely
If your home is cold, using space heaters can help heat individual rooms. However, make sure to use them safely to prevent fire hazards. Never leave a space heater running without supervision, and keep it away from fire-prone objects. If possible, invest in a safe, energy-efficient heater for your living space.
3. Seal Drafts
Cold air leaks through cracks and holes in doors and windows. To prevent cold drafts, use weather stripping or draft stoppers. Closing curtains at night can also keep cold air out and minimise heat loss.
4. Eat Warming Foods
Consuming hot meals and drinks can help your body maintain its temperature. Foods like soups, stews, and hot beverages provide warmth and nourishment, which can help keep you feeling comfortable during cold weather.
5. Exercise Regularly
Even if it’s cold, try to get regular exercise. Physical activity helps improve circulation, boost energy, and increase body warmth. If it’s too cold to exercise outdoors, consider doing indoor activities like yoga, stretching, or simple cardio exercises.
6. Stay Hydrated
Cold, dry air can dehydrate your body, which can further impair your immune system. Drinking plenty of water throughout the day helps your body regulate its temperature and keeps your skin and respiratory system healthy.
7. Get Regular Heating Maintenance
If you live in an older home, your heating system could be inefficient or outdated. Set up frequent maintenance checks for your furnace, air ducts, and insulation. Keeping your home properly heated can reduce your risk of cold-related health issues.
Conclusion
Living in a cold house can have more serious health consequences than you may realize. From cardiovascular strain and respiratory issues to muscle stiffness and poor mental health, the cold can take a toll on your body. Understanding these risks is the first step in protecting yourself and your family. By taking the necessary precautions to stay warm and healthy, you can minimize the dangers of living in a cold environment and enjoy a safer, more comfortable winter season.
