Curriculum
Programme Structure
The programme is structured in 5 modules, listed below in order of study.
01
Physiology of thermoregulation and water balance
- Mechanisms of heat loss of the human body: conduction, convection, radiation and evaporation.
- Water Homeostasis: The role of the kidneys, the skin and the endocrine system in fluid balance.
- Function of sweat and electrolytes: Analysis of the loss of sodium, potassium and chloride during physical activity.
- The hypothalamus as a biological thermostat: central response to the increase in internal temperature.
- Individual risk factors: age, acclimatization, level of body fat and previous medical conditions.
02
Dehydration: levels, clinical signs and diagnosis
- Classification of dehydration: Mild (sed), moderate (dry mouth, fatigue) and severe (shock) grades.
- Physical evaluation of the state of hydration: test of the skin fold, capillary filling and mucosal status.
- Biological markers: Analysis of urine colour, heart rate and variations in blood pressure.
- Cognitive alterations due to fluid deficiency: confusion, irritability and loss of judgment.
- Common electrolyte imbalances: hyponatremia (excess water) vs. hypertonic dehydration.
03
Pathologies caused by heat and thermal emergencies
- Heat exhaustion: symptoms, progression mechanisms and immediate cooling protocols.
- Heatstroke: Identification of the medical emergency, anhidrosis and multi-organ failure.
- Heat cramps and heat syncope: causes, support treatment and salt replacement.
- Heat edema: Pathophysiology of inflammation in the limbs due to peripheral vasodilation.
- Clinical differentiation between severe exhaustion and heat stroke with neurological compromise.
04
Effects of UV radiation and solar skin lesions
- Classification of solar radiation: UVA, UVB spectra and their penetration into the dermis layers.
- Solar erythema (burns): degrees of involvement, symptoms and pain management.
- Photosensitivity and allergic reactions: medicines and substances that increase vulnerability to the sun.
- Cumulative damage and chronic pathologies: actinic keratosis and foundations of skin cancer prevention.
- Eye injuries from sun exposure: photokeratitis and prevention of radiation cataracts.
05
Equipment, logistics and crisis management
- The Thermal Kit: Essential supplies for hydration and care of burned skin.
- Use of balloon thermometres and heat stress sensors for group decision making.
- Evacuation protocols for patients with heat stroke in remote areas or boats.
- Education and team awareness: How to promote the culture of self-protection and mutual care.
- Communication with emergency services: accurate description of thermal symptoms by radio or telephone.
