Welcome to icliniq.com.
Yes, it is easy to catch cold, particularly if you are in a cold, wet and windy weather. Also, exposure to extremely cold temperature affects you in many ways and can cause frost nip (first stage of frostbite), trench foot (prolonged exposure of feet to cold) and frostbite (damage to skin due to cold), chilblains (itchy swelling in hands due to blood vessel inflammation) and last but not the least hypothermia (low body temperature).
On the top of that, you being a marathon runner and a fit person will be having less amount of subcutaneous fat, which usually insulates you from cold temperatures like a quilt. Moreover, after a workout and sweating a lot, if you do not compensate by drinking water, you may get dehydrated and that further predisposes you to the ill effects of cold exposure. Well, I would advise you to take a cab to return home, particularly when the weather is so cold.
Here are few don'ts you need to keep in mind.
- Do not smoke as smoking constricts your blood vessels and impairs your body's natural defensive mechanisms to fight cold temperatures.
Also, I suggest few dos post workout.
- Do wear good warm winter clothes.
- If you sweat a lot during workout, have water or juice to compensate for the loss of fluid and thus avoid dehydration.
- You can take warm drinks like coffee, soups and lukewarm water.
- You can always take a warm shower.
If you have any frost bite or any blisters, then immediately do not pour or immerse in hot water. Take a pair of extra clothes and never run in cold weather in wet clothes. Take a taxi particularly now as you have flu. You may take lukewarm showers. Warm shower definitely helps you to fight cold, but does not compensate for the cold injury. The length of exposure to cold temperatures depends on the variables such as the temperature, warm clothes you wear and your physical condition. Do take care of your health as the degree emotional health that is crucial for your living is directly proportional to your health.
