Section: Coach Hot — Practicing with Heat
This section covers Chapter 2, Lessons 2.1 through 2.4.
Part A — Vocabulary (20 points, 2 points each)
Select the best answer for each question.
1. Heat acclimatization is:
A) Moving to a warmer climate permanently B) The body's adaptation to repeated heat exposure over 7-14 days C) Wearing extra clothing D) An emergency response
2. Löyly refers to:
A) A Finnish coastal city B) The burst of humid air released when water is poured over heated sauna stones; central to Finnish tradition C) A type of cold practice D) A medical term
3. Banya is:
A) An African heat tradition B) The Russian heat-bath tradition, often paired with cold immersion C) A medical heat treatment D) An exercise device
4. Onsen refers to:
A) A type of Japanese tea B) The Japanese hot-spring bathing tradition C) A cold-water plunge D) A Korean sauna
5. Sodium conservation in heat acclimatization means:
A) Adding more salt to the diet B) The acclimatized body's ability to produce more dilute sweat (lower sodium per liter) C) Storing sodium in the kidneys D) Avoiding all sodium
6. Hyperhydration in this chapter refers to:
A) Drinking more than thirst demands; can contribute to hyponatremia B) Optimal hydration C) A medical condition D) A type of sports drink
7. Euhydration is:
A) Dehydration B) The state of being well-hydrated C) Excess hydration D) A measurement of urine
8. A randomized controlled trial (RCT) is:
A) An observational study B) The strongest research design for showing causation, with random assignment to intervention and control groups C) A survey D) A case report
9. An observational study differs from an RCT in that it:
A) Cannot show any results B) Observes existing behavior without controlling who does what; weaker for causation C) Uses larger samples D) Is more rigorous
10. Preseason acclimatization period is:
A) A weekend retreat B) A structured period at the start of athletic season for gradual heat adaptation C) A pre-game ritual D) Free time before tryouts
Part B — Concept Comprehension (20 points, 2 points each)
Select the best answer for each question.
11. In a traditional Finnish sauna, the burst of humid air released when water is poured over hot stones is called:
A) Banya B) Löyly C) Onsen D) Tummo
12. A large 20-year observational study of middle-aged Finnish men found that more frequent sauna use was associated with:
A) Higher rates of cardiovascular events B) No change in mortality C) Lower rates of fatal cardiovascular events and all-cause mortality D) Unchanged outcomes
13. The strongest type of research study for proving causation is:
A) An observational study B) A case study C) A randomized controlled trial (RCT) D) A survey
14. Heat acclimatization typically takes approximately how long to develop most of its effect?
A) 1-2 days B) 7-14 days C) 1-2 months D) A full year
15. A useful adaptation of heat acclimatization is:
A) Greater sweat sodium concentration B) More dilute sweat (sodium conservation) C) Higher heart rate at the same effort D) Reduced plasma volume
16. School athletic preseason acclimatization periods exist primarily to:
A) Help athletes lose weight B) Build cardiovascular fitness C) Allow gradual heat adaptation and reduce heat illness risk D) Test which athletes are toughest
17. During sustained heat exposure lasting more than 60 minutes, an electrolyte solution is generally more useful than plain water because:
A) It tastes better B) It contains sodium that helps replace what is lost in sweat C) It is colder D) It contains more water
18. Drinking large amounts of plain water during very long, heavy sweat exposure can cause:
A) Improved performance B) Hyponatremia — dangerous dilution of blood sodium C) Faster heart rate only D) No measurable effect
19. Coach Cold and Coach Hot are described as teaching:
A) Two unrelated practices that should not be combined B) The same autonomic nervous system from opposite sides C) Opposite philosophies D) Practices for different age groups
20. Coach Hot deliberately does NOT give students a specific sauna protocol because:
A) The science is unsettled B) Specific temperatures, durations, and frequencies are individual and require informed adult/medical context, and the curriculum teaches frameworks rather than prescriptions for minors C) Saunas are dangerous D) Saunas do not work
Part C — Application (30 points, 6 points each)
Write 2-4 complete sentences for each question. Show your reasoning.
21. A friend says, "Saunas detox your body of the bad foods you eat." Using what you have learned in this chapter and the previous one, explain why this framing is not accurate and offer a more accurate framing.
22. Describe what happens to plasma volume, sweat onset, heart rate, and sodium loss across a two-week heat acclimatization period.
23. You are helping plan a long Saturday hike on a hot day. Apply the "before, during, after" hydration framework. What specifically would you recommend?
24. Why is the sauna-plunge tradition (heat alternated with cold) found in so many cultures around the world? What might these cultures have learned through long practice that modern science is now studying?
25. Coach Hot deliberately does not give specific sauna temperatures, durations, or frequencies. Explain at least two reasons why that decision is appropriate for a high school health curriculum.
