Heat rashes, miliaria and prickly heat are just a few of the names for the condition that causes small red pimples or bumps on the skin. According to the website Dr. Greene, children can be especially sensitive to heat and this is what normally causes these types of rashes in children. The Mayo Clinic reports that you normally do not need treatment for the rash unless it causes swelling, pain, fever, chills or seems infected.
Miliaria Crystallina
According to the Mayo Clinic, miliaria crystalline is one of the mildest forms of heat rashes that can affect children. The rash usually occurs during hot weather and can come and go as long as the weather remains hot. Dr. Green reports that this type of rash will normally occur wherever the child has been wearing clothing. This particular rash causes tiny, clear blisters to break out on the skin but does not cause reddening of the skin. In addition, the miliaria crystalline rash is not itchy and is rarely painful. The Mayo Clinic reports that the rash usually heals itself and usually will not require any treatment.
Miliaria Rubra
Miliaria rubra is a heat rash that the Mayo Clinic reports is somewhat less common. Although it usually occurs in adults, it can also occur in older children. According to the Mayo Clinic, miliaria rubra affects the outer layer of skin and can occur in a child that has been bed-bound or lying in bed for long periods in a hot or humid location. The Mayo Clinic reports that the symptoms of this rash include red bumps or pimples, an itchy or prickly feeling on the rash and little sweating on the area of the rash. The miliaria rubra rash usually heals once the environment has cooled down and any wet bed linens and clothing have been changed.
Miliaria Profunda
Miliaria profunda rash is a heat rash that occurs in adults but can sometimes occur in children who have been suffering from repeated bouts of miliaria rubra. According to the Mayo Clinic, miliaria profunda affects the deeper layer of skin called the dermis. This rash can present after you have been sweating because of exercising or playing outside. The Mayo Clinic reports that the symptoms of this rash include lesions that look like goose bumps on the skin. If you child has this rash, you might also notice that they have stopped perspiring and are nauseous and perhaps even vomiting. The Mayo Clinic also reports that the child may also have a rapid pulse and be suffering from heat exhaustion. The miliaria profunda rash will usually heal on its own as long the child is cooled off and has any sweaty clothing changed.
