Insensible perspiration, also known as transepidermal water loss, is the passive vapour diffusion of water through the epidermis. Insensible perspiration takes place at an almost constant rate and reflects evaporative loss from the epithelial cells of the skin. [1] Unlike sweating, the lost fluid is pure without additional solutes. For this ...
These are termed "insensible fluid losses" as they cannot be easily measured. Some sources say insensible losses account for 500 to 650 ml/day (0.5 to 0.6 qt.) of water in adults, [12] [14] while other sources put the minimum value at 800 ml (0.8 qt.). [15] In children, one calculation used for insensible fluid loss is 400 ml/m 2 body surface area.
TEWL in mammals is also known as insensible water loss (IWL), as it is a process over which organisms have little physiologic control and of which they are usually mostly unaware. Insensible loss of body water can threaten fluid balance; in humans, substantial dehydration sometimes occurs before a person realizes what is happening.
Excess free water or hypotonic water can leave the body in two ways – sensible loss such as osmotic diuresis, sweating, vomiting and diarrhea, and insensible water loss, occurring mainly through the skin and respiratory tract. In humans, dehydration can be caused by a wide range of diseases and states that impair water homeostasis in the body ...

Loss of body sodium and consequent intravascular water (due to impaired reabsorption of salt and water in the tubules of the kidneys) Osmotic diuresis: the increase in urine production due to an excess of osmotic (namely glucose and urea) load in the tubules of the kidneys; Overuse of pharmacologic diuretics
Dehydration can occur as a result of diarrhea, vomiting, water scarcity, physical activity, and alcohol consumption. Management of dehydration (or rehydration) seeks to reverse dehydration by replenishing the lost water and electrolytes. Water and electrolytes can be given through a number of routes, including oral, intravenous, and rectal.
Of all the age groups, children aged 0–4 years had the highest death rate and also non-fatal injury rate. In 2013, among children 1 to 4 years old who died from an unintentional injury, almost 30% died from drowning. [8] These children most commonly drowned in swimming pools, often at their own homes.
