Altitude sickness is the body's natural reaction to travelling to a higher altitude. When we change our environment, we need time to adapt as the atmosphere's pressure decreases and our bodies have to deal with a lack of oxygen. Altitude sickness has nothing to do with age or physical condition. It can affect any rider, whether they are young or old, athletic or a Sunday jogger, a smoker or not, or a biking rookie or veteran. During our
motorcycle tours in the heart of Ladakh, some people get used to the change in altitude better than others. Symptoms such as nausea, tiredness, headaches and even dizzy spells may appear at around 3,000 m altitude, or even 2,000 m for some bikers.
