It is more common in indoors season because there is less environmental factors like wind. However, it is very uncommon for outdoors due to wind, changing lighting, and weather.
It really makes a difference whether you drink between shots or not. You don't need to drink in order to keep your body functioning "strengthwise" like when running, but you need to keep it working precisely. Especially when it's warmer/hot outside it's advisable to drink regularly.
