To prevent altitude sickness during a trek, ascending gradually and staying hydrated is the most effective approach. When you ascend gradually, you allow your body time to acclimatize to the decreasing oxygen levels at higher elevations. This gradual ascent helps your body adapt, reducing the risk of altitude sickness, which can occur when the body does not have enough time to adjust.

Staying hydrated is equally important because dehydration can exacerbate symptoms of altitude sickness. Proper hydration helps maintain blood volume and circulation, which are crucial for getting enough oxygen to your tissues. It also supports various bodily functions that are affected by high altitude.

In contrast, rapid ascent can overwhelm the body’s ability to acclimatize, significantly increasing the likelihood of altitude-related illnesses. Insufficient hydration, or neglecting to rest and recover at altitude, can also contribute to the risk of developing altitude sickness. Thus, the combination of gradual ascent and proper hydration is key to preventing this condition and ensuring a safer and more enjoyable trekking experience at high altitudes.
