Summer heat making you feel more exhausted than normal? Or has COVID quarantine encouraged you to spend more time on mountain trails instead of staying indoors? Here are a few tips as we round out summer.
Heat illness is a spectrum of disease that ultimately culminates into heatstroke. Heatstroke separates into two different categories: Classic and Exertional. Classic heatstroke is predominately in elderly patients residing in poorly regulated temperature environments. Exertional heatstroke is predominately in athletes who overexert themselves during high temperature and humidity. Heatstroke presents as elevated core body temperature >40C and central nervous system dysfunction. The treatment for both is supportive cooling as soon as possible. First-line cooling measure involves ice water immersion. Third line treatment is evaporative cooling, which is typically utilized in medically complex or elderly patients for ease of monitoring; however, this also cools at a slower rate when compared to ice water immersion.
High altitude illness consists of High Altitude Pulmonary Edema (HAPE) and Acute Mountain Sickness (AMS), which can progress to High Altitude Cerebral Edema (HACE).
Two recent publications in ACEP Now by Dr. Ashley Jacobson and Dr. Neha Raukar discuss heat illness and high altitude illness.
