What are the best ways to keep warm outdoors?
A lot of people are reluctant to go out in the cold during the winter season. It's a real shame as there are many ways in which you can protect yourself from low or even sub-zero temperatures.
You've probably been told it a million times since you were a kid, but it bears repeating. You need to wrap up warm. The clothes you wear outdoors trap warm air inside them. A good starting point is wearing a cotton T-shirt to absorb sweat and thereby neutralize humidity, which can exacerbate feelings of cold.
Then wear a sweater or warm jacket made of a high quality material like wool, cashmere or alpaca. Finally, a decent coat or windcheater on top, as well as a scarf and most importantly a woolly hat or beanie, as 30% of warmth leaves the body via the head.
Does drinking hot drinks before going out help?
Warm is probably a better option than hot, actually. When you swallow a very hot drink, the feeling of warmth you get quickly fades, as your body struggles to find its regular temperature. Meanwhile, a warm drink won't leave you with that annoying cold sensation afterwards.
If you can, go for tea, bouillon or soup before going out, rather than coffee or any type of alcohol. That's because they dilate blood vessels and therefore cause body temperature to drop. Blood moves from the body's core to the surface of our skin, which makes us feel warmer than we actually are. That can be dangerous.
How about when we get outside?
It might seem obvious, but can easily be forgotten. To keep your body temperature up outside, you need to stay active. Simply walking is enough to stimulate blood flow. Move your arms as you walk, and don't keep your hands in your pocket, no matter how tempting it might be.
Tapping your face gently will also help stimulate blood flow. Your hands are particularly sensitive to the cold, so don't forget to wear gloves or mittens. You can also rub your hands together or use hand warmers, which are very practical when it gets extra cold.
If you're still feeling cold any time you go out, you may want to talk to your doctor about it. Sometimes sensitivity to cold is caused by an underlying health condition. like iron deficiency, a low body mass index, poor blood circulation or hypothyroidism. There you have it.
