Hyperthermia, also known simply as overheating, is a condition in which an individual's body temperature is elevated beyond normal due to failed thermoregulation.The person's body produces or absorbs more heat than it dissipates.
Dogs are even more susceptible than humans to heat stroke in cars, as they cannot produce whole-body sweat to cool themselves. Leaving the dog at home with plenty of water on hot days is recommended instead, or, if a dog must be brought along, it can be tied up in the shade outside the destination and provided with a full water bowl.

Symptoms include lethargy, weakness, depression, pale mucous membranes, fever, and blood in the urine. Hypoxia may lead to forebrain disease, increased heart rate and respiratory rate, and liver or kidney disease. Animals suffering from this disease must be taken to a veterinarian immediately. Treatment includes fluid support and blood ...
Thermoregulation is the ability of an organism to keep its body temperature within certain boundaries, even when the surrounding temperature is very different. A thermoconforming organism, by contrast, simply adopts the surrounding temperature as its own body temperature, thus avoiding the need for internal thermoregulation.
Older dogs, similar to this 10-year-old Neapolitan Mastiff, often grow grey hairs on their muzzles, and some dogs grow grey hair all over. Not all dogs gain grey hair when aging. Aging in dogs varies from breed to breed, and affects the dog's health and physical ability. As with humans, advanced years often bring changes in a dog's ability to ...
Another risk factor is premature birth in which medical intervention, such as premature birth prevention or C-section delivery, can be used as prevention for intrauterine hypoxia. [ 37 ] Studies have shown a connection between tetrahydrobiopterin (BH 4 ) deficiency and hypoxia-ischemia brain injury, though further studies need to be done. [ 38 ]
As in other mammals, human thermoregulation is an important aspect of homeostasis. In thermoregulation, body heat is generated mostly in the deep organs, especially the liver, brain, and heart, and in contraction of skeletal muscles. [1] Humans have been able to adapt to a great diversity of climates, including hot humid and hot arid.
Targeted temperature management (TTM), previously known as therapeutic hypothermia or protective hypothermia, is an active treatment that tries to achieve and maintain a specific body temperature in a person for a specific duration of time in an effort to improve health outcomes during recovery after a period of stopped blood flow to the brain.
