The face is another common area for hyperhidrosis to be an issue. Sweating uncontrollably is not always expected and may be embarrassing to people with the condition. It can cause both physiological and emotional problems in patients. It is generally inherited. [20] It is not life-threatening, but it is threatening to a person's quality of life ...
An early stage of hyperthermia can be "heat exhaustion" (or "heat prostration" or "heat stress"), whose symptoms can include heavy sweating, rapid breathing and a fast, weak pulse. If the condition progresses to heat stroke, then hot, dry skin is typical [ 2 ] as blood vessels dilate in an attempt to increase heat loss.

Sweating sickness is "an acute, febrile, tickborne toxicosis characterized mainly by a profuse, moist eczema and hyperemia of the skin and visible mucous membranes." [1] It affects cattle, mainly calves, [2] mostly in southern and eastern Africa. It is caused by toxins that develop in some ticks of the Hyalomma truncatum species. [3]
The LD 50 of this toxin has been measured to be approximately 2.5–3 ng/kg, [2] [3] making it second only to the related botulinum toxin (LD 50 2 ng/kg) [4] as the deadliest toxin in the world. However, these tests are conducted solely on mice, which may react to the toxin differently from humans and other animals.
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]
