Study Summary
This trial looks at how men and women respond to heat acclimation differently. They will be looking at changes in core temperature, heart rate, and sex hormones.
Who is the study for?
This trial is for healthy men and women aged 18-40 with a BMI under 30. Women must have regular menstrual cycles or be on oral contraceptives. Participants should exercise regularly, avoid caffeine before tests, and not consume alcohol or engage in strenuous activity prior to sessions. Those with heart, lung, kidney disorders, heat intolerance issues, recent COVID-19 infection or certain gastrointestinal diseases cannot join.Check my eligibility
What is being tested?
The study investigates how different levels of female sex hormones affect the body's adaptation to heat. It involves young adults undergoing a standard heat acclimation protocol through treadmill walking exercises in hot conditions over ten days while monitoring changes in core temperature, heart rate, and hormone levels.See study design
What are the potential side effects?
Since this trial involves physical exercise in a controlled hot environment rather than medication or medical procedures, side effects may include typical responses to heat exposure such as dehydration symptoms (thirsty/dizzy), overheating (heat exhaustion), muscle cramps and fatigue.
