This project will identify the efficacy of cooling modalities aimed to attenuate excessive elevations in skin and internal body temperatures during physical activity in well-healed burn survivors. The investigators will conduct a randomized crossover design study. Non-burned control subjects, subjects who experienced burns covering \~20% to 40% of their body surface area, and subject having burns \>40% of their body surface area will be investigated. Subjects will exercise in heated environmental conditions while receiving the following cooling modalities: no cooling, fan only, skin wetting only, and a combination of fan and skin wetting.

Inclusion Criteria (non-burned individuals):
* Healthy male and female subjects
* 18-65 years of age.
* Free of any underlying medical conditions
Exclusion Criteria (non-burned individuals):
* Any burn-related injuries resulting in at least one night of hospitalization.
* Heart disease or any other chronic medical condition requiring regular medical therapy including cancer, diabetes, and hypertension.
* Abnormalities detected on routine screening
* Individuals who participate in a structured aerobic exercise training program at moderate to high intensities.
* Current smokers, as well as individuals who regularly smoked within the past 3 years.

Inclusion Criteria (burn survivors):
* Healthy male and female subjects
* 18-65 years of age.
* Free of any underlying medical conditions
* Having a burn injury covering 20-40% or \>40% of the participant's body surface area; at least 50% of those burn injuries must be full thickness that required skin grafting.
* Participants must have been hospitalized due to the burn injury for a minimum of 15 days

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
