High-altitude (HA) areas have tough conditions like low oxygen, extreme cold, strong sunlight, and dry climates. Every year, millions of people travel to these regions for work, sports, or leisure, especially in places important for defense like India’s northern and northeastern borders. These conditions weaken the immune system, making people more prone to infections and illnesses. Common problems include infections like those affecting the skin, lungs, stomach, or brain are also more likely due to poor hygiene and harsh conditions. Careful planning and checking for health issues before traveling to high altitudes can help prevent serious problems and manage illnesses better.
