The causes of itchy skin rashes are too numerous to detail here in this brief article, but, the most likely cause is exposure to an irritant. It could be your clothing, the soap or detergents that you use or it could be your water.
Once you rule out a fungal infection, which affects about 20% of the population at any given moment, you know that you have not been bitten by an insect or handled a poisonous plant, like sumac, and you do not have an underlying medical condition , like celiac disease, the logical source is something in your environment.
When you have itchy skin rashes that appear suddenly, you can easily look for something "new" in your environment. Did you buy new clothing, change the brand of detergent that you use or buy a different personal care product, such as a lotion, shampoo or body wash? Did you move recently, change jobs or buy a new car?
Any new product that you bought into your home or anything different that you have recently been exposed to could be the problem. And, as I mentioned, it could be your water.
Chlorine is a common skin irritant. At certain times of the year (usually during the spring and summer), chlorine levels in publicly treated supplies can be quite high. Chlorine combined with hot water in the shower strips your skin's natural oils, causing itching, dryness and flaking. In some cases, a rash may appear, as a result of scratching or simply due to exposure.
Lead is also found in many water supplies around the world, as well as in older homes and office buildings. Lead exposure does not typically cause itching, but it can cause a rash. Traces of environmental toxins commonly found in publicly treated water supplies may be liable for a number of itchy skin rashes, particularly when no other source can be found.
There are several ways to tie the itching at home, but if the rash spread or begin to "weep", you should see your doctor. Weeping indications infection and a spreading rash could be a symptom of an underlying medical condition.
Cortisone ointments can be purchased over the counter and usually provides immediate relief. An antihistamine, such as Benadryl, may be helpful, but remember that the side effects of antihistamines include drowsiness. So, if you expect to be driving, it is best to choose another approach. Even the "spray-on" antihistamines cause drowsiness in many people, so use with care.
If you have frequent itchy skin rashes, a shower filter can be very beneficial. By removing, chlorine, lead and other common contaminants, an effective shower filter can reduce your exposure to those toxins, which could be the cause of your rash.
If your skin is dry and itchy most of the time, the water that you shower and bathe in is the likely cause. Dermatologists and beauty experts, alike, often recommend shower filters. I personally recommend them for anyone that wants to put an end to excessive dryness and itchy skin rashes.
