Why Do You Get Sick When You Don’t Wear a Coat?
Mom was right when she told you to wear a coat. Putting on a coat before you go outside in winter is a good idea when it is cold. Tweet This It could protect you against getting sick, but maybe not for the reasons that you think.
How Does a Wearing a Coat Help Prevent Getting Sick?
Here are four ways that a warm winter coat can lower your risk of getting a winter cold or worse.
Surface Area and Perspiration
Running about in cold weather, or even just walking through layers of snow can trigger your body’s response to perspire. As this sweat evaporates in the dry air, it can chill you very quickly, and the chill can lower your immune system, making it more likely that you will get sick. Tall adults and children both have more relative skin external surface area and less insulating fat, making these groups especially vulnerable to getting a chill.
Inflammation and Exposed Skin
Exposed skin can become irritated and inflamed when exposed to the cold air, wind and snow or ice. Thin clothing will not offer enough protection from the winter elements. Not only is sore skin uncomfortable, it can also crack and allow bacteria to get in under the surface, leading to infection.
Circulation and Organ Protection
Without a warm coat, a body exposed to the cold goes into hibernation mode. It redirects warm blood to the vital organs, leaving the fingers, toes, nose and ears more vulnerable to frostbite, even if gloves, footwear and a scarf cover them. Keeping your core warm reduces the risk.
Cold and the Immune System
There has been a lot of back and forth over whether or not exposure to cold air affects the immune system. Every few years, a new study seems to cancel out the old one. The most recent research done by British cold researchers found a connection to cold exposure and illness. They say that nasal passages may be more vulnerable to infections when exposed to cold air. This is a great reason to add a warm scarf to your warm winter coat when you bundle up.
