When we think about things that trigger allergies, we usually imagine something that people eat or drink. You know, that kid who will be dead in seconds if he eats peanuts or the girl who bolts to the bathroom after she drinks milk.
But not all allergic reactions are to food or drink. This list will take you through some of the stranger allergies our human bodies can fall victim to.
10. Cold Temperatures

Most people don’t particularly like being cold. But for a sufferer of cold urticaria, low temperatures bring on a whole new world of discomfort. Symptoms can range from redness, welts, and itching on skin that has been exposed to the cold all the way to systemic symptoms like headaches, diarrhea, tachycardia, and even anaphylaxis.
In most cases, cold urticaria can be diagnosed by a cold stimulation test. (An ice cube in a plastic bag is placed on the arm for five minutes, and the results observed.) If welts appear after a period of 5–10 minutes of rewarming, the test is considered positive. If the ice cube test is negative, cold urticaria cannot necessarily be ruled out.
Unfortunately, there are a number of atypical presentations of cold urticaria which are less easily diagnosed. This includes delayed cold urticaria, in which reactions to the cold stimuli may take 3–24 hours to appear, and localized cold urticaria, in which only certain parts of the body will react.
Treatment for cold urticaria typically involves the avoidance of cold temperatures. This includes cold foods and beverages, immersion in cold water, and exposure to cold weather. Antihistamines can also be used to alleviate symptoms. weird things,weird things,weird things
