How cold weather affects the human body:
We all experience cold weather differently. If you are tall, you tend to become cold faster than a shorter person. Taller people have a bigger surface area; meaning heat is lost from the body quicker. Even though people react to cold weather differently, as a species we are extremely adaptable.
What happens when we get cold? The human body has several defense mechanisms to try and boost our core temperature when it gets chilly. Our muscles shiver and teeth chatter. Our hairs rise and our flesh forms 'goosebumps' - a kind of evolutionary echo from the times when our ancestors were covered in fur. The hypothalamus, the gland in the brain that acts as your body's thermostat, stimulates these reactions to keep the body's vital organs warm, at least until it can find some kind of warmth and shelter.
The hypothalamus's mission is to keep the core warm at all costs - sacrificing the extremities if need be. That's why we feel pins and needles in our fingers and toes in extreme cold - the body is keeping its warm blood close to the center, constricting blood supply in the outer regions such as the end of our limbs. In extreme cold, and especially if bare skin is open to the elements, this effect can end in frostbite. Blood flow is reduced, and the lack of warm blood can lead to tissue freezing and rupturing.
Cold weather can put increased stress on our cardiovascular system. Cold temperatures cause your blood vessels to constrict, shallow breathing, and a slight thickening of the blood. These changes can cause chest pain in people with heart disease. When you're outside in cold conditions, make sure to wrap up warm, being careful to cover up your extremities.
Cold temperatures can cause problems for asthma sufferers. Cold, dry air causes the air passages in the lungs of some asthma sufferers to contract, making it difficult to breathe. When it comes to the cold, it is not just about being outside. It is important to understand that keeping your house warm during the winter months is essential.
Cold, dry air can also worsen conditions such as eczema by drying out the skin. Even if you may not feel like it, it's important to drink lots of water in the winter months in order to stay hydrated and avoid dry, flaky skin.
Therefore, use of a heater during the winter is a must.
