Hypoxia is a condition in which the body or a specific tissue is deprived of an adequate supply of oxygen. This can lead to a range of health problems, including decreased cognitive function, fatigue, shortness of breath, and even tissue damage or cell death in severe cases. Hypoxia can result from a variety of factors such as high altitudes, lung conditions, cardiovascular diseases, or underlying health conditions. Researchers study hypoxia to understand its effects on the body and develop treatments or interventions to mitigate its negative impact.
