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.
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 ...
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 ...

The figure for water fraction by weight in this sample was found to be 58 ±8% water for males and 48 ±6% for females. [4] The body water constitutes as much as 75% of the body weight of a newborn infant, whereas some obese people are as little as 45% water by weight. [5] This is due to how fat tissue does not retain water as well as lean tissue.
Share of the population without access to an improved water source, 2020. Global access to clean water is a significant global challenge that affects the health, well-being, and development of people worldwide. While progress has been made in recent years, millions of people still lack access to safe and clean drinking water sources.
