Summary
Physical exertion in hot climates increases body temperature, risking heat illness. Glutamine, an amino acid, may help prevent heat injury by addressing underlying biological stress mechanisms.
Area of Science:
- Environmental Physiology
- Nutritional Science
- Occupational Health
Background:
- Physical work in hot climates elevates body temperature, leading to heat-related illnesses like heat exhaustion and stroke.
- Individuals in physically demanding occupations in hot environments face increased risk of heat injury.
- Complex mechanisms including dehydration, tissue damage, oxidative stress, and inflammation contribute to heat illness.
Purpose of the Study:
- To review current literature on the role of glutamine during heat stress.
- To explore glutamine's potential as a preventative nutrient for heat illness.
- To understand glutamine's impact on mechanisms underlying heat illness.
Main Methods:
- Literature review of existing studies on glutamine and heat stress.
- Analysis of research investigating biological stress and nutrient requirements.
- Examination of evidence for glutamine's role in mitigating heat illness mechanisms.
Main Results:
- Glutamine is conditionally essential during biological stress due to high consumption rates.
- Evidence suggests glutamine may be a crucial nutrient during heat stress.
- Combined with other measures, glutamine might help mitigate heat illness.
Conclusions:
- Glutamine plays a role in managing biological stress, relevant to heat exposure.
- Further research is warranted to confirm glutamine's efficacy in preventing heat illness.
- Nutritional strategies, including glutamine supplementation, could be part of a multi-faceted approach to heat illness prevention.

Methods of reducing fever
643
The signs and symptoms of fever include hot and dry skin, flushed face, thirst, muscle aches, anorexia, headache, tachycardia, tachypnea, and fatigue. Elevated body temperature is reduced using two methods: pharmacological and nonpharmacological. Proper identification and treatment of the root cause of a fever is of utmost importance.

Hypoglycemia and Glucagon
152
Without prolonged fasting, healthy individuals maintain blood glucose levels above 3.5 mM due to a well-adapted neuroendocrine counterregulatory system that effectively prevents acute hypoglycemia, a potentially life-threatening condition. The primary clinical scenarios for hypoglycemia encompass diabetes treatment, inappropriate production of endogenous insulin or insulin-like substances by tumors, and the use of glucose-lowering agents in non-diabetic individuals. Notably, hypoglycemia in the...

Increased Body Temperature
642
A body temperature above 38°C (100.4 °F) is known as fever or pyrexia, and a person with fever is termed 'febrile.' Typically, the hypothalamus, a part of the brain that acts as the body's thermostat, regulates body temperature through a thermoregulatory setpoint. It receives signals from cold and warm thermal receptors throughout the body and adjusts the body's temperature accordingly. Fever occurs when this hypothalamic setpoint is altered, usually in...

Homeostatic Imbalances in Body Temperature
100
Hyperthermia occurs when the body's temperature becomes unusually high, often due to heat exposure, intense physical activity, or certain illnesses. This condition can create a dangerous cycle where elevated body temperature increases the metabolic rate, generating more heat and potentially leading to organ failure and brain damage. A severe form of hyperthermia, called heat stroke, can raise body temperature to life-threatening levels. Fever, on the other hand, is a controlled form of...

Decreased Body Temperature
602
A decreased body temperature can occur in patients with hypothermia and frostbite. Heat loss with extended cold exposure overpowers the body's ability to create heat, resulting in hypothermia. Core temperature readings help classify hypothermia. Mild hypothermia is temperatures between 32 °C (89.6 °F) and 35°C (95 °F) and is caused by impaired thermoregulation. Moderate hypothermia is temperatures between 28 C (82.4 °F) and 32 °C (89.6 °F) caused by...
