Hypothermia is defined as a body core temperature below 35.0 °C (95.0 °F) in humans. [48] Symptoms range from shivering and mental confusion, [49] to hallucinations and cardiac arrest. [48] In addition to cold injuries, breathing cold air can cause dehydration, because the air is warmed to body temperature and humidified from body moisture. [15]

Merely thinking about or seeing someone yawning can make you yawn. But why?
Kleiber found that an organism's basal metabolic rate could be predicted by taking 3/4 the power of the organism's body weight. This finding was noteworthy because the inversion of the scaling exponent, between 0.2 and 0.33, also demonstrated the scaling for both lifespan and metabolic rate, and was colloquially called the "mouse-to-elephant ...
So instead of freaking out if you start yawning every day around 2 p.m., talk to your doctor about what could be going on. That way, you won’t be up all night worrying! Up Next:
Senescence (/ s ɪ ˈ n ɛ s ə n s /) or biological aging is the gradual deterioration of functional characteristics in living organisms. Whole organism senescence involves an increase in death rates or a decrease in fecundity with increasing age, at least in the later part of an organism's life cycle.
