Study how high altitude affects heart and breathing measures
This study looks at how exposure to high altitude changes measurements related to your heart and breathing. It may help scientists better understand health effects of altitude so they can improve safety and care.
Courmayeur, AostaAges 18 years+ - NCT07664462Recruiting
Heat and Altitude: Male Exercise Study
This study tests how your body handles working in heat when you are also at a simulated high altitude. The results could help understand physical limits and safety in jobs or sports.
Ottawa, OntarioAges 18–70 - NCT07615478Recruiting
Hot spring therapy for reducing fatigue during altitude rowing training
This study tests whether soaking in hot springs can help young rowers feel less tired and recover better while training at high altitude. Researchers want to see if the hot water helps the body's natural fatigue-fighting systems work better.
Macao, MacaoAges 12–16 - NCT07536477Recruiting
High-flow oxygen versus standard oxygen for altitude lung swelling
This trial tests whether high-flow oxygen (delivered through a special nasal tube) works better than standard oxygen therapy for a condition called high-altitude pulmonary edema (HAPE)—fluid buildup in the lungs caused by rapid ascent to high altitude. The study aims to see which approach helps patients breathe better and recover faster.
Xigazê, TibetAges 18 years+ - NCT07142590Recruiting
Iron needs in people living at high altitude
This study measures how much iron your body absorbs and loses if you live at high altitude. It helps researchers understand iron requirements for people in this environment, using a new testing technique.
Zurich, Canton of ZurichAges 18–45 - NCT07063732Recruiting
Ketone drink, high altitude, and brain blood flow during exercise
This trial tests whether a ketone monoester supplement affects brain blood flow and exercise performance at high altitude. It may help us understand how to support brain function during altitude exposure.
Bishop, CaliforniaAges 18–35 - NCT02301663Recruiting
Stress test study of heart blood-flow issues in adults
This study tests a new kind of stress test to understand how small blood-vessel heart problems relate to heart relaxation problems in people with angina (chest pain) but no blocked arteries. It may help doctors learn better ways to diagnose and guide treatment for these conditions.
Los Angeles, CaliforniaAges 18–60 - NCT06204731Recruiting
Exercise in low oxygen for young men
This study tests whether exercising in a low-oxygen environment (like high altitude) can affect stress, inflammation, and energy in your body. It is for young males who are generally healthy and can exercise safely.
KrakowAges 19–29 - NCT07755384Recruiting
Stomach and throat exam study at high altitude
This study looks at what doctors see in the upper digestive tract (stomach and food pipe) of people living at high altitude, using a sedated endoscopy (a camera tube down the throat while you sleep). It helps understand how high altitude affects the digestive system.
Yushu, QinghaiAges 18 years+ - NCT07431580Recruiting
How low oxygen affects heart function in asthma
This study tests how your heart's right ventricle adapts when you breathe lower-oxygen air (like at high altitude). If you have well-controlled asthma, researchers want to see if your heart handles the challenge differently.
Zurich, Canton of ZurichAges 18–80 - NCT07431554Recruiting
Studying heart function in low oxygen after HAPE
This study looks at how the right side of the heart responds to low oxygen levels in people who have had high altitude pulmonary edema (HAPE) in the past. It will help researchers better understand right heart function.
ZurichAges 18–80 - NCT07431567Recruiting
How low oxygen affects heart function in healthy adults
This study tests how your heart’s right ventricle handles low oxygen (like at high altitude) in healthy adults. You will be exposed to a low-oxygen environment for a short time to see how your heart responds.
Zurich, Canton of ZurichAges 18–80 - NCT07423988Recruiting
Sleep changes at high altitude for Pic du Midi staff
This study looks at how sleep quality changes when you work overnight at high altitude (2877m) at the Pic du Midi observatory, compared to sleeping at home. It helps understand the effects of high-altitude work on rest.
Toulouse, OuiAges 18–65 - NCT06852924Recruiting
Inhaled nitric oxide for HAPE treatment trial
This trial tests if inhaled nitric oxide helps people with high-altitude pulmonary edema (fluid in the lungs from high altitude). It may offer a new treatment option for those with mild to moderate symptoms.
Lhasa, TibetAges 18–65 - NCT07312227Recruiting

Common questions
- Are there clinical trials for altitude?
- Yes. Clin2 currently lists 30 recruiting altitude studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a altitude trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a altitude trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
