Sufficient stress from extreme external temperature may cause injury or death if it exceeds the ability of the body to thermoregulate. Hypothermia can set in when the core temperature drops to 35 °C (95 °F). [2] Hyperthermia can set in when the core body temperature rises above 37.5–38.3 °C (99.5–100.9 °F).
The swim bladder, gas bladder, fish maw, or air bladder is an internal gas-filled organ in bony fish (but not cartilaginous fish [1]) that functions to modulate buoyancy, and thus allowing the fish to stay at desired water depth without having to maintain lift via swimming, which expends more energy.

There is generally a reduction in the amount of air that the lungs can hold (vital capacity) and changes in expiratory function and lung elasticity. [80] [81] When the exposure to oxygen above 0.5 bar (50 kPa) is intermittent, it permits the lungs to recover and delays the onset of toxicity. [82]
3,3′-Diaminobenzidine (DAB) is an organic compound with the formula (C 6 H 3 (NH 2) 2) 2. This derivative of benzidine is a precursor to polybenzimidazole, which forms fibers that are renowned for their chemical and thermal stability. [1] As its water-soluble tetrahydrochloride, DAB has been used in immunohistochemical staining of nucleic ...
With higher temperature and humidity, viruses can’t survive outside a host as long. Research suggests flu viruses in high humidity can cling to water molecules and then fall out of the air. That ...
Anyone who shares a bedroom is likely familiar with what can sometimes become a bitter battle over the temperature at bedtime. Studies have shown that 50 percent of couples prefer different ...
Which temperature of water works best for an athlete depends on a number of factors, said David Putrino, director of rehabilitation innovation at the Mount Sinai Health System in New York City.
As of 2016 there is no effective measurement of body temperature distribution which can usefully predict gas transfer rates into or out of tissues based on temperature distribution or effective perfusion, or any evidence based way to integrate temperature measurement into decompression algorithms.
