Research on exertional heat illness (EHI) has been increasing over the last decade, but a gap in how to translate results to prevention strategies and policies may exist. Research evaluating common predisposing factors will be reviewed to develop focused prevention strategies for EHI in active populations. Constructing the framework of prevention policies for EHI is provided throughout the course. Only inherent and underlying intrinsic risk factors will be covered in this course.

Chapters & Learning Objectives

Download Learning Objectives

1. Introduction

The difference between extrinsic and intrinsic risk factors is clarified. Types of prevention strategies are defined.

2. Intrinsic Risk Factors: Medications and Comorbidities

In this chapter, the instructor provides examples of which comorbidities may be predisposing factors for EHI and why. This chapter also discusses which medications affect hydration status and body temperature and therefore are predisposing factors. Examples of policy statements are given that can be used for different active populations.

3. Intrinsic Risk Factors: Body Size and Mindset

The instructor will explain why being overweight is a predisposing factor for EHI, while debunking a common myth about this body type. This chapter will also present research as to the prevalence of overweight and obese individuals in active populations. This chapter will include a description of how an overzealous attitude can be a predisposing factor for EHI. Discussion of how to use the research results for the practical application of prevention strategies will be presented. Examples of policy statements are given that can be used for different active populations.

4. Intrinsic Risk Factors: Underlying Physiologic Individual limitations

In this chapter, the instructor explains why febrile and gastrointestinal illnesses are predisposing factors for EHI. Research is discussed, as well as possible explanations for sleep deficits as risk factors. The chapter also reviews how an individual’s physical conditioning level can be a risk factor in certain exercise. There is a discussion of how to use the research results for the practical application of prevention strategies. Examples of policy statements are given that can be used for different active populations.

5. Intrinsic Risk Factors: Environment-Related Physiologic Individual Limitations

This chapter starts off with why hypohydration is a primary etiology for EHI. There’s also a discussion of the benefits of heat acclimatization. The instructor provides research supporting why inadequate heat acclimatization is a predisposing factor and discusses how to use the research results for the practical application of prevention strategies. Examples of policy statements are given that can be used for different active populations.
