Russ (right) and his son Kevin work on a great spaghetti dinner for the group. Activities such as getting water and preparing dinner help the time go by when in camp, and will also help you to acclimate to the high altitude.
One of the big mistakes I often see people do, is to get into camp early and then crash inside their tent for the rest of the day. Your oxygen intake goes down when you do this, and the result can be dizziness and/or headaches. Staying active during the daylight hours will usually speed up the Acclimatization Process
This is not only important for feeling good during the day, but even more so during the night. Research on the White Mountain's Summit
revealed that once you stop activity and lie down its like being nearly 2,000 feet higher in terms of its affect on the body. So that being said, being involved in light activity during the day rather than resting in your tent, helps a bunch. There will be plenty of time for sleeping later on when it gets dark.
