  2. Human body temperature - Wikipedia

    en.wikipedia.org/wiki/Human_body_temperature

    The body temperature of a healthy person varies during the day by about 0.5 °C (0.9 °F) with lower temperatures in the morning and higher temperatures in the late afternoon and evening, as the body's needs and activities change. [15]

  3. Diurnal air temperature variation - Wikipedia

    en.wikipedia.org/wiki/Diurnal_air_temperature...

    Peak daily temperature generally occurs after noon, as air keeps absorbing net heat for a period of time from morning through noon and some time thereafter. Similarly, minimum daily temperature generally occurs substantially after midnight, indeed occurring during early morning in the hour around dawn, since heat is lost all night long.

  4. Cold and heat adaptations in humans - Wikipedia

    en.wikipedia.org/wiki/Cold_and_heat_adaptations...

    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).

  5. The best temperature for sleep to get a better night's rest - AOL

    Our body temperature decreases as the body primes for sleep and increases when it's time to wake up. The deepest stages of sleep coincide with the times that body temperature is the lowest.

  6. Human thermoregulation - Wikipedia

    en.wikipedia.org/wiki/Human_thermoregulation

    Simplified control circuit of human thermoregulation. [8]The core temperature of a human is regulated and stabilized primarily by the hypothalamus, a region of the brain linking the endocrine system to the nervous system, [9] and more specifically by the anterior hypothalamic nucleus and the adjacent preoptic area regions of the hypothalamus.

  7. Sleep - Wikipedia

    en.wikipedia.org/wiki/Sleep

    [23] [35] Sleepiness increases during the night. REM sleep occurs more during body temperature minimum within the circadian cycle, whereas slow-wave sleep can occur more independently of circadian time. [31] The internal circadian clock is profoundly influenced by changes in light, since these are its main clues about what time it is.

  8. Chronotype - Wikipedia

    en.wikipedia.org/wiki/Chronotype

    A person's chronotype is the propensity for the individual to sleep at a particular time during a 24-hour period. Eveningness (delayed sleep period; most active and alert in the evening) and morningness (advanced sleep period; most active and alert in the morning) are the two extremes with most individuals having some flexibility in the timing ...
