Cold Weather's Hidden Health Hazards Revealed

As autumn progresses, medical expert Dr. Claire Agathou highlights the profound impact of cold weather on the human body. Viruses propagate more easily in cold, dry air, and indoor proximity increases transmission. Cold air can also impair the nose's defenses and sudden temperature drops may reduce immunity, leading to more winter infections.

Cold weather induces vasoconstriction, narrowing blood vessels and potentially increasing blood pressure and heart rate. This makes individuals with heart conditions, diabetes, and smokers particularly vulnerable. Cold, dry air can also trigger bronchospasm, intensifying symptoms for those with asthma or COPD.

Skin conditions like eczema often flare up in winter due to dry air and indoor heating, compromising the skin barrier. Raynaud's condition, characterized by blood vessel narrowing in fingers and toes, is also a common trigger during colder months.

Joint pain and stiffness can increase in winter due to reduced blood flow to muscles and decreased activity. Arthritis sufferers frequently report worsening symptoms, as cold temperatures make nerve endings more sensitive, amplifying pain signals.
