Hypohidrosis is a medical condition in which a person exhibits diminished sweating in response to appropriate stimuli. In contrast with hyperhidrosis , which is a socially troubling yet often benign condition, the consequences of untreated hypohidrosis include hyperthermia , heat stroke and death. [ 2 ]
Most people with hypohidrotic ectodermal dysplasia have a reduced ability to sweat (hypohidrosis) because they have fewer sweat glands than normal or their sweat glands do not function properly. Sweating is a major way that the body controls its temperature; as sweat evaporates from the skin, it cools the body.
Focal hyperhidrosis is increased or excessive sweating in certain regions such as the underarm, palms, soles, face, or groin. Hyperhidrosis is excessive sweating, usually secondary to an underlying condition (in which case it is called secondary hyperhidrosis) and usually involving the body as a whole (in which case it is called generalized ...

Sudomotor function refers to the autonomic nervous system control of sweat gland activity in response to various environmental and individual factors. Sweat production is a vital thermoregulatory mechanism used by the body to prevent heat-related illness as the evaporation of sweat is the body’s most effective method of heat reduction and the only cooling method available when the air ...
A significant feature of many ED types is the absence or reduced function of sweat glands, leading to conditions known as hypohidrosis or anhidrosis. The inability to produce sufficient sweat disrupts normal thermoregulation, particularly in warm environments, and can lead to overheating or hyperthermia.
A thermoregulatory sweat test evaluates the body's response to a thermal stimulus by inducing sweating through the use of a hot box ⁄ room, thermal blanket or exercise. Failure of the topical indicator to undergo a colour change during thermoregulatory sweat testing can indicate anhidrosis and/or hypohidrosis (see Minor test). [14]
