Drink a lot of water: The best way to combat altitude sickness during high altitude trekking is to consume a lot of fluids(the right kind!!). At altitude due to the dry air your body loses more water then in similar conditions in the plains. So always keep a bottle by your side and drink water after regular intervals during your trek.
Take Deep Breaths: This seems counter intuitive. However, your body absorbs more oxygen when we take long breaths compared to when breathing fast. So during high altitude trekking try taking rhythmic deep breaths especially when going uphill.
Slow Down: Try observing village women in mountainous areas climbing a steep path. They stroll slowly. Try doing the same.You will realise that it’s better to go at a pace you can maintain for a really long time than to have to stop constantly to catch your breath.
Small Steps Going Uphill: The steeper the incline, the smaller the steps. This tip reduces the effort needed to climb.
Keep Your Head Covered: During high altitude trekking it is essential to keep your forehead covered with a bandana,cap etc. to protect yourself from chilly winds. Leave your head uncovered and chances are you’ll end up with a really bad headache.
Climb High Sleep Low: As a general rule of thumb whenever possible try to climb to a higher altitude by day and sleep at a lower altitude by night. This always helps you acclimatise during a high altitude trek.
A fantastic High Altitude trek we recommend for beginners is the Kuari Pass Trek which gives takes you into the Nanda Devi Sanctuary
