Apparent temperature, also known as "feels like", [1] [2] is the temperature equivalent perceived by humans, caused by the combined effects of air temperature, relative humidity and wind speed. The measure is most commonly applied to the perceived outdoor temperature.
The wind chill factor makes the weather feel colder under windy conditions than calm conditions even though a glass thermometer shows the same temperature. Airflow increases the rate of heat transfer from or to the body, resulting in a larger change in body temperature for the same ambient temperature.
A generalized view of the heat index showing how the perception of heat by the human body increases with temperature but more rapidly at higher humidity levels. The heat index of a given combination of temperature and humidity is defined as the dry-bulb temperature which would feel the same if the water vapor pressure were 1.6 kPa. Quoting ...
A feeling thermometer, also known as a thermometer scale, is a type of visual analog scale that allows respondents to rank their views of a given subject on a scale from "cold" (indicating disapproval) to "hot" (indicating approval), analogous to the temperature scale of a real thermometer.
This is the coldest air the city has experienced since the thermometer dipped to 12 degrees below zero on Jan. 15, 1957 -- an impressive feat given that no snow was on the ground to chill the air ...
Instant-read thermometers provide quick, accurate readings, probe thermometers are best for oven-roasting, digital thermometers offer precise results and alarms, and traditional dial thermometers ...
The wet-bulb globe temperature (WBGT) is a measure of environmental heat as it affects humans. Unlike a simple temperature measurement, WBGT accounts for all four major environmental heat factors: air temperature, humidity, radiant heat (from sunlight or sources such as furnaces), and air movement (wind or ventilation).

Redshift is an application that adjusts the computer display's color temperature based upon the time of day. The program is free software, and is intended to reduce eye strain as well as insomnia [3] (see Sleep#Circadian clock and Phase response curve#Light).
