What should I do if I have altitude sickness?

When experiencing altitude sickness, immediately stop physical activity and rest, replenish fluids and energy, use oxygen to relieve discomfort, take targeted medications, and adjust altitude. If severe symptoms such as persistent intense headache, difficulty breathing, or confusion occur, seek immediate medical attention at a hospital in the high-altitude area.

1. Immediately stop activities and rest: Once symptoms of altitude sickness appear, cease walking, climbing, or any other physical exertion immediately. Sit or lie down in a cool, well-ventilated place. Avoid strenuous exercise to reduce cardiac strain and lower the body's oxygen consumption, helping to alleviate dizziness and fatigue.

2. Replenish fluids and energy: Drink warm water or light salt water in small amounts frequently—avoid consuming large quantities at once. Eat easily digestible carbohydrate-rich foods such as bread or porridge to restore energy, maintain normal metabolism, and reduce discomfort.

3. Use oxygen to relieve symptoms: If portable oxygen cylinders or oxygen bags are available, administer oxygen promptly. Control the flow rate and duration of oxygen inhalation to improve hypoxia and relieve symptoms such as chest tightness, shortness of breath, and headaches. Be cautious not to over-oxygenate, which may cause adverse effects.

4. Take targeted medications: Under medical guidance, take medications designed to alleviate altitude sickness, such as Rhodiola rosea preparations or Gao Yuan An capsules, to help the body adapt to high-altitude conditions and reduce symptoms. Do not self-medicate without supervision to avoid potential adverse drug reactions.

5. Adjust altitude: If symptoms persist or worsen, descend to a lower altitude as soon as conditions allow. Reducing elevation decreases the physiological stress of high-altitude exposure and helps relieve symptoms. Ensure someone accompanies you during descent for safety.

For daily prevention, gradually acclimatize by increasing altitude slowly before entering high-altitude areas; avoid rapid ascent. Carry essential medications and oxygen supplies, maintain warmth to prevent colds, eat light and balanced meals, and avoid alcohol and excessive fatigue to support your body’s adaptation to high-altitude environments.
