Keeping it cool when it gets hot

Human thermoregulation in a warm environment Thermoregulation is the ability for an organism to control body temperature within a specified physiological range even when environmental temperatures vary. A recent article published in Physiological Reviews explored thermoregulation in humans and how various factors such as age, body shape, adaptation, and biological sex impact a person’s ability to maintain body temperature. They also explored how various diseases such as multiple sclerosis, diabetes, […]

Adapting to rising temperatures

In a new review article published in Physiology, Dr. Jonathon Stillman from San Francisco State University explores how populations of animals and humans may respond to increasing frequency of heat waves. According to Dr. Stillman, the past decade has produced some of the hottest years on record, resulting in the loss of human and animal life. Both the length and intensity of these heat waves are expected to increase, which […]

Heat stress in livestock

With the approach of summer, a timely study was published in the American Journal of Physiology – Regulatory, Integrative and Comparative Physiology on whether inflammation plays a role in heat stress-related complications in muscles. Heat stress is a major problem in the livestock industry. In the United States alone it is reportedly associated with a loss of approximately $158 billion annually in the swine industry. To cool off, swine seek shade and often mud baths […]
