Winter brings cold, but also a hidden health risk: household mould. Known as a “silent killer,” it grows in damp and can be dangerous if not dealt with. Let’s see what mould is, why it’s risky, and how to handle it with NHS – backed advice.
What Is Mould and Why Worry?
Mould is a microscopic fungus. It grows in damp places, forming fuzzy black, white, or green patches and has a musty smell. In the UK, about two million live in mould – affected homes. It releases harmful spores. Long – term exposure can cause breathing problems, allergies, and asthma attacks. It’s especially risky for kids, the elderly, and those with weak immune systems.
Why Mould Grows in Winter
In winter, cold and more indoor activities create perfect mould – growing conditions. Condensation from cooking, showering, or drying clothes indoors gives the moisture mould needs. If not removed, it becomes a mould breeding ground, especially in bathrooms, kitchens, and near windows.
Dangers of Mould: Beyond Just Ugly
Mould isn’t just unappealing; it’s a real health threat.
- Respiratory Issues: Inhaling spores can irritate lungs and worsen asthma.
- Allergic Reactions: It can cause skin rashes, runny noses, sneezing, and red eyes.
- Serious Risks: For vulnerable people, long – term exposure can lead to life – threatening problems. Black mould is especially dangerous as it releases harmful mycotoxins.
