Mountain sickness can happen when your body does not get enough time to adjust to high altitude. It is common during treks that take you above 2,500 meters. Mild symptoms may include headache, tiredness, dizziness, loss of appetite, and difficulty sleeping. These symptoms should not be ignored, especially if they become worse.
The best way to prevent altitude sickness is to ascend slowly and give your body enough time to acclimatize. Drink plenty of water, eat regular meals, get enough rest, and avoid alcohol and smoking at higher elevations. Following a well-planned itinerary with proper acclimatization days can make a big difference.
If you start feeling unwell, inform your guide immediately and avoid going higher until you feel better. In serious cases, descending to a lower altitude is the safest option. Your trekking guide can help monitor your condition and decide the safest next step, allowing you to enjoy your Himalayan adventure with greater confidence.
