A study conducted by McCance et al. found out that the Bedouins produced less sweat in comparison to people living in fair climatic conditions (269). In this regard, this adaptation is important in extremely hot conditions since individuals will be able to lose less water from their body systems. In effect, these individuals will not be dehydrated and will survive in hot conditions better than other individuals will. In addition, less sweating enables individuals to use little water and consume less food regardless of the heat in the individual’s environment. Thus, less consumption of water helps the Bedouins conserve their water reserves while using the little water available to them.
