Their movement, heart rate, heart rate variability, body temperature, physical activity, ambient temperature, and snow depth were measured to identify the drivers of the start and end of hibernation for bears. This study built the first chronology of both ecological and physiological events from before the start to the end of hibernation in the ...
The Dutch call the presence a nachtmerrie, the night-mare. [17] The "merrie" comes from the Middle Dutch mare, an incubus who "lies on people's chests, suffocating them". This phenomenon is known among the Hmong people of Laos, [20] who ascribe these deaths to a malign spirit, dab tsuam (pronounced "dah chua"), said to take the form of a ...
The usual first suspect is heatstroke — critical increases in body temperature that cause organs to fail. When inner body temperature gets too hot, the body redirects blood flow toward the skin ...
A cold weather strategy is to temporarily decrease metabolic rate, decreasing the temperature difference between the animal and the air and thereby minimizing heat loss. Furthermore, having a lower metabolic rate is less energetically expensive. Many animals survive cold frosty nights through torpor, a short-term temporary drop in body ...
The harder your heart has to work to pump blood throughout your body while you’re not exerting yourself, the higher your resting heart rate. That’s why a lower resting heart rate is indicative ...
Neurogenic shock is a distributive type of shock resulting in hypotension (low blood pressure), often with bradycardia (slowed heart rate), caused by disruption of autonomic nervous system pathways. [1] It can occur after damage to the central nervous system, such as spinal cord injury and traumatic brain injury.
A lower resting heart rate or slower heartbeat will fill the ventricles/heart better and allow for more of a forceful contraction of blood out to the rest of the body, says Dr. Weinberg. “A fast ...
Until the body temperature is raised to near-normal levels: Types: Primary hypothermia: caused by exposure to a cold environment; Secondary hypothermia: caused by an underlying pathology that prevents the body from generating enough core heat. Causes: Mainly exposure to cold weather and cold water immersion: Risk factors
