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.
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 ...
Web corpus searches show that the acronym TEWL is about 40 times more common than TWL in reference to transepidermal water loss. A large advantage of TEWL is that it has higher specificity to that sense than does TWL, which has more alternative senses, including, most importantly, two other senses having to do with evaporation of body water: thermal work limit (TWL), which is the highest ...

In physiology, body water is the water content of an animal body that is contained in the tissues, the blood, the bones and elsewhere. The percentages of body water contained in various fluid compartments add up to total body water (TBW). This water makes up a significant fraction of the human body, both by weight and by
Fluid replacement or fluid resuscitation is the medical practice of replenishing bodily fluid lost through sweating, bleeding, fluid shifts or other pathologic processes. . Fluids can be replaced with oral rehydration therapy (drinking), intravenous therapy, rectally such as with a Murphy drip, or by hypodermoclysis, the direct injection of fluid into the subcutaneous tis
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.
