Our skin – our body’s biggest organ – is an amazing thing. Protecting us from the outside world, it also connects us to the people and things that we love. Here you can learn more about your skin and some common skin conditions.
We wouldn’t be who we are without our skin. It protects us from the outside world, maintains our body temperature, creates essential vitamin D, and helps us interact with the people we love. But it’s also sensitive and needs our care and attention to stay healthy.
Our largest organ has three distinct parts:
Our skin is the body’s biggest organ, and it performs many functions. A major role is for protection, including against physical aggressors such as friction, chemicals and infection, as well as against harmful UV rays. As well as protecting against external forces, it’s also our largest sensory organ and we receive lots of information about the world through the nerve endings in our skin. These experiences range from heat, cold and pain to the comforting touch of friends and loved ones.
Another major role of the skin is temperature regulation. Our skin contains about 2-5 million sweat glands, and we can sweat up to 10 or more litres per day in hot climates to help our bodies cool down. When it’s cold, sweat production and blood supply to the skin is reduced to help conserve heat in deeper organs.
