The surprising ways cold weather can affect your health

Cold weather can significantly impact our health in various ways. It not only spreads illnesses like the flu but can also exacerbate heart and lung conditions. Certain individuals, including those with chronic health issues, older adults, and young children, are more susceptible to the effects of cold weather. Deaths often spike shortly after a cold snap, and can remain elevated for up to four weeks afterward.
Hypothermia, a dangerous drop in core body temperature, accounts for only a small fraction of cold-related deaths. In the UK, around 50 deaths are directly attributed to hypothermia each year. However, heart and lung problems resulting from the cold affect considerably more individuals. When we're cold, our bodies work to maintain a steady core temperature of around 37.5°C. This process can lead to increased blood pressure and heightened clotting risks, potentially causing heart attacks or strokes.
Cold and flu viruses are more prevalent in winter due to factors such as people spending more time indoors, causing viruses to spread more easily. Cold air can dry out the nasal passages and throat, allowing viruses to pass through more easily. Some viruses thrive in cooler conditions, while exposure to cold can suppress the immune system, increasing the risk of bronchitis and pneumonia.
Cold weather can pose risks even when temperatures are above freezing. Health effects can begin to be felt at temperatures between 4°C to 8°C, and below 18°C, the body begins to show adverse effects. Cold can also worsen arthritis symptoms and increase the risk of falls and injuries. Cold weather can also lead to carbon monoxide poisoning, damp, and mould growth in poorly heated homes. Elderly, young children, and those with heart, lung, or dementia conditions are most at risk.
To stay well during cold weather, it's recommended to heat your home to at least 18°C, move around regularly to maintain blood circulation, and wear multiple layers of clothing. Regular boiler servicing and reducing draughts can also help. Check on vulnerable neighbors and seek help from local services if needed.
