Normal sweating helps to keep the body temperature steady in hot weather, during a high temperature (fever), or when exercising.
Excessive sweating (hyperhidrosis) means that you sweat much more than normal. Even when you are not hot, anxious, or exercising, you make a lot of sweat.
Hyperhidrosis can manifest itself in many forms, and excessive facial sweating is on of them. When this condition occurs it extends to more than just the face, also affecting the scalp and even the neck. When the scalp is affected by excessive sweating, the hair may look oily and dirty. Even though this condition is known as facial sweating, the negative effects are serious as far as the hair is concerned. Blow drying the hair may prove to be a difficult task. The condition may manifest itself in the most embarrassing situations, while talking to people, or having a business lunch. With female patients this poses an even bigger obstacle, as they have a hard time putting on make up and maintaining it in good shape. Excessive sweating will dilate the skin pores and the result is that the makeup will run over their face, creating an unpleasant situation. Facial blushing is another condition that may appear in combination with the excessive facial sweating.
Excessive underarm sweating also known as axillary hyperhidrosis usually starts at puberty, or can become apparent after or during pregnancy. Although neurologic, metabolic, and systemic diseases can be known to be the culprit of this problem, it can also occur in people that are otherwise healthy. Triggers include emotion and heat, or they can experience sweating all the time regardless of these factors.
Causes of Itchy Skin In some cases, the symptoms of itchy skin are seen at the affected part of the body, while at other times, they can be observed all over the body. Though a person can experience itchy skin without noticing any changes in the skin, the 'itch' is usually accompanied by symptoms like redness, bumps, blisters and dry or cracked skin. These symptoms can worsen if the affected area is scratched as the disruption of skin makes it vulnerable to bacterial infection, and therefore scratching should be strictly avoided. Discussed below are some health conditions which are likely to cause utter discomfort owing to severe itching associated with them. Allergies: Allergic reactions to certain substances, which are triggered when the individual comes in contact with the allergens, are known to cause skin itch in some people. These allergens include certain foods, pollen, plants like poison ivy and poison oak, lacquer, in some people even cosmetics and hair dye, chemicals, wool, etc. In this case, the itching sensation may either last for a few hours or even go on for a few days.
