This document discusses heat-related illnesses, including heat exhaustion and heat stroke. It provides information on prevention, symptoms, assessment, and treatment for each condition. For heat exhaustion, it recommends stopping activity, moving to a cool place, cooling measures, oral rehydration, and monitoring vital signs. Hospitalization may be needed for severe cases or if symptoms persist. Heat stroke is a medical emergency, with symptoms including high body temperature, altered mental status, and organ dysfunction. Immediate cooling through methods like cold water immersion is critical to prevent complications and death. Treatment also includes IV fluids, monitoring for complications, and slow cooling once the temperature drops below 102F.
Heat-related illness and injuries are the most frequent cause of environmentally related death, occurring more often than illness or injury related to lightning, tornado, hurricane, flood, cold, and winter-related fatalities.
Such illnesses and injury range from minor conditions such as heat rash, edema, cramps and fainting to moderate conditions such as heat exhaustion. Heat stroke is a major heat emergency, representing complete breakdown of the body's ability to regulate its temperature.
Presentation prepared by John W. Lyng, MD, FACEP, NREMT-P. Dr Lyng is Medical Director or North Memorial Ambulance & Air Care and an Emergency Department Physician at North Memorial Medical Center in Minneapolis.

Heat related illnesses simply explained, spectrum of hyper and hypothermia related clinical scenarios with symptoms, diagnosis, management and prognosis.
The winter season is almost upon us. Workers need to work in cold outdoor environments while other recreate in outdoor environments. Either way, people are exposed to the cold. This is a comprehensive view of the cold stress and how to prevent exposure and what to do if your are exposed to the cold, wind, and rain/snow.
The dog days of summer aren’t just hard on our furry friends.
Anyone who spends significant time out in the heat, including your employees, needs to stay vigilant for signs of an HRI. Here are the big four, and what you and your crew members need to be on the lookout for.

Oak Hospital Birmingham has very kindly provided some excellent and valuable
advice on heat injury prevention following worrying comments at the club
about running in the heat.
This is a really useful guide which is applicable to training and racing in
warm weather.

Ice rescue and immersion hypothermia slide shareRommie Duckworth
In cases of environmental hypothermia, the common sense approach of “Warm them up!” may be the worst thing that you can do for your patient. In this presentation we learn the deadly effects of immersion, after-drop and cold induced vasodilation and how to properly differentiate between mild, moderate and severe hypothermia. We will discuss wilderness EMT and extreme environment treatment algorithms and how they apply to your service area.
The drawbacks of climate change are so overt. The Disturbance of Great Ocean Conveyor currents led to the extreme changes in temperature around the globe in the form of a cooler northern, warmer tropical and cooler snowy winter, warmer summer. Many deaths from hypothermia were reported especially in refugee camps as it is not well equipped. Hypothermia is a medical emergency that occurs when the body loses heat faster than it can produce heat, causing a dangerously low body temperature. Normal body temperature is around 98.6 F (37 C). Hypothermia occurs as the body temperature falls below 95 F (35 C). When body temperature drops, heart, nervous system and other organs can't work normally. Left untreated, hypothermia can eventually lead to complete failure of heart and respiratory system and eventually to death.
Heat Stress is a serious concern in occupational health and safety.
It is important we carry out more awareness on heat stress to reduce incidents relating to heat stress.
