TAKE AWAY FROM OUR COLD FACTS
Have you heard of the #ColdFacts we’ve been talking about during this winter 2017/2018 on our Facebook Page ? If you missed it, here’s a quick recap of it before the beautiful and hot summer days.
Cold Fact #1 – You don’t get a cold because it is cold.
In fact, it can be a factor, but you mostly get it because you were in contact with a virus. During winter, people tend to ventilate less their home, which is building a favorable environment for viruses. Therefore, make sure to often ventilate your home during winter!
Cold Fact #2 – Some parts of your body should be more covered than others.
Indeed, in cold conditions, you should not only cover the trunk regions, but also your extremities such as hands and feet. The head is also an important area for heat loss, so do not forget to put a hat on. The key point when active in the cold is to make sure you don’t get too hot. The moisture from your sweat would replace the air trapped close to your body, and you will end up being cold. In a sense, you may want to stay cool to stay warm. A convenient way to achieve this balance is to remove the gloves and beanie before you feel too hot.
Cold Fact #3 – Putting your hands in your pockets do not warm them
How cold your hands are is determined by the amount of blood flowing there, which depends on the temperature of your internal organs, not that of your hands. You get cold hands mainly because your body is cold. So when you have cold hands, nothing but an increase in your body temperature can warm them up. This can be caused by an increase in the environmental temperature, in the insulation you wear on the main body regions (trunk or head), or in the intensity of your activity.
Putting your cold hands in your pockets will improve your comfort for a moment, but it will not increase the temperature of your body. Pull them out and you will soon find them uncomfortably cold again. So in the cold, if you want to warm your hands up, put a hat or jacket on and start moving!
Cold Fact #4 – Being cold is a matter of mental
Being cold is a matter of mental… at least the way you cope with it. Unlike thermal sensation, thermal comfort is an emotional and affective experience, which depends on an individual’s history and expectation. It reflects the condition of mind expressing satisfaction with the environmental conditions and refers to the subjective indifference to this environment. Several factors can influence this experience: movement, distraction, habituation, motivation. It is even suggested that some mental practices can reduce cold discomfort. Did you know that Tibetan monks were practicing Tummo Meditation, also known as “Inner fire meditation”? This meditation consists in visualizing heat to be able to bear cold conditions, but also to improve concentration and vitality. Try it out and let us know!
Cold Fact #5 – A lack of social interactions can litterally make you feel cold
According to a study in psychological science in Toronto, a lack of social interactions can literally make you feel cold. So during winter, join outdoor activity groups, and enjoy your time outside!
Cold Fact #6 – Heat is not only leaving your body through your head
You might have heard that your head represents approximately 10% of your heat loss Actually, before you start to thermoregulate in cold conditions, heat will escape from all your body parts. Therefore if your entire body but your head is covered, then heat will flow away from your head more than from your chest, or arms.
Cold Fact #7 – Cold conditions make you burn calories
When exposed to the cold, your body may have to shiver, which can increase the energy expenditure to a level fivefold the resting rate. This requires calories to be burnt but it is very uncomfortable and can be dangerous. Recent research suggests that a non-negligible amount of calories is used to produce heat prior to shivering, which may constitute an alternative way to increase one’s daily energy expenditure.
Cold Fact #8 – Wearing multiple layers of clothes keeps you warm
Wearing multiple layers of clothes may keep you warmer than one single thick layer. The protection from the cold offered by your clothing is due to the amount of air that is trapped between your skin and the environment. This amount is greater when using multiple layers than when wearing one single layer. Plus, it is very convenient to then adjust the number of layers to the intensity of your activity to remain comfortable.
