How does the concept of high-altitude sickness affect individuals in mountainous regions

- **Decreased Oxygen Levels:** At high altitudes, the air pressure is lower, leading to decreased oxygen levels in the blood, resulting in symptoms like headaches, fatigue, and dizziness. - **Acute Mountain Sickness (AMS):** AMS is a common form of high-altitude sickness, characterized by symptoms such as nausea, vomiting, and shortness of breath. - **High-Altitude Pulmonary Edema (HAPE) and High-Altitude Cerebral Edema (HACE):** In severe cases, high-altitude sickness can progress to HAPE and HACE, which can be life-threatening if not treated promptly. - **Recent Reports:** Recent reports highlight the increasing number of hikers and climbers experiencing high-altitude sickness due to a lack of acclimatization and overexertion, emphasizing the importance of proper preparation and awareness of the risks.
