Allen's rule - Hare and its ears on the Earth [1]. Allen's rule is an ecogeographical rule formulated by Joel Asaph Allen in 1877, [2] [3] broadly stating that animals adapted to cold climates have shorter and thicker limbs and bodily appendages than animals adapted to warm climates.
A flameless lighter is a safe alternative to traditional lighters. The flameless lighter uses an enclosed heating element which glows, so that the device does not produce an open flame. Typical flameless heating elements are an electrically heated wire or an artificial coal.
According to The Guardian, scientists have traced this top cold-weather myth to a United States Army manual from the 1970s recommending a hat in the cold because "40 to 45 percent of body heat" is ...
Bergmann's rule - Penguins on the Earth (mass m, height h) [1] Bergmann's rule is an ecogeographical rule that states that, within a broadly distributed taxonomic clade, populations and species of larger size are found in colder environments, while populations and species of smaller size are found in warmer regions.
Researchers believe versions of the dry-heat practice date back some 10,000 years, and though Finland is often credited as the origin place of saunas, heat therapy has a home in many cultures ...
The law holds well for forced air and pumped liquid cooling, where the fluid velocity does not rise with increasing temperature difference. Newton's law is most closely obeyed in purely conduction-type cooling. However, the heat transfer coefficient is a function of the temperature difference in natural convective (buoyancy driven) heat transfer.
Temperature influences the body’s circadian rhythm, which regulates sleep-wake cycles, says Dr. Vendrame. In other words, your body’s temperature tells you when to sleep and when to be awake.
Origins of heat and cold adaptations can be explained by climatic adaptation. [16] [17] Ambient air temperature affects how much energy investment the human body must make. The temperature that requires the least amount of energy investment is 21 °C (70 °F). [5] [disputed – discuss] The body controls its temperature through the hypothalamus.
