Allergies are very common. 1 in 5 people at some time experience suffering due to allergies. There are many different causes of allergy and the symptoms vary from mild to life-threatening ones.
An allergy occurs when your immune system reacts to certain substances in the environment. These substances may be harmless for other people, but not with some others.
Also known as allergens, these substances can also be found in dust mites, pollen, pets, insects, food, and medicines. But did you know that you can also suffer from allergy because of the weather — most especially when it is cold?
What is Cold Urticaria?
Cold Urticaria is a skin reaction to cold which immediately appears minutes after you are exposed to the cold weather or atmosphere. You will notice that some reddish and itchy welts or hives are starting to develop.
Those who are suffering from cold urticaria could experience different symptoms. For some people, swimming in cold water may lead to very low blood pressure, fainting, and even shock. Other signs and symptoms of cold urticaria may also include:
–Temporary reddish and itchy welts on the area of the skin which is exposed to cold
-Experiencing a worsening reaction when the skin gets warm
-Swelling of hands when holding cold objects
-Swelling of lips when consuming cold drinks or food like ice cream
Severe reaction to this allergy may include:
–Whole body response (anaphylaxis) which may cause fainting, racing heart, swelling of limbs or torso, and shock
-Swelling of the throat and tongue; hence, making it difficult to breathe
Cold urticaria begins when the skin is exposed to a sudden drop in air temperature or if the environment is cold. Damp and windy conditions can also affect your condition. Each episode of this allergic reaction may last for about two hours.
The worst reactions happen when you are swimming in cold water and your skin is fully exposed. Reactions may lead to loss of consciousness and possible
drowning, so it is of a huge importance that one knows when someone has this allergy to coldness.
If symptoms begin to show, take anti-histamine immediately. It is better to take the non-drowsy one too. Replacing your regular soap with sulfur soap may also help. When taking a shower, use warm water.
If you have skin reactions after being exposed to cold, make sure to see your doctor immediately. Even if the reactions are mild, your doctor may want to rule out underlying conditions that may be the reason for the problem.
