Inadequate food intake results in body weight loss which can eventually impair physical and mental performance. Poor food intake decreases the intake of salt necessary to retain water. Individuals consume almost half of all fluids at mealtimes. If soldiers skip meals or voluntarily limit their food intake, then the amount of fluids consumed also decreases. Water and Food-Borne Illness Emphasis should be placed on following proper field sanitation practices to prevent disease in hot environments.
High temperatures encourage microbial growth and activity in both water and food sources.
Hence, command emphasis on proper field hygiene and sanitation techniques is critical. Adjust fluid intake and work-rest cycles as temperature varies. Soldiers working in warm weather require approximately 4 to 6 quarts of water per day and need more water as physical work and temperatures increase. Military personnel working in hot environments require 10 to 12 quarts of water per day . It is imperative that commanders consider the amount of water necessary at different environmental temperatures to support the corresponding work-rest schedules.
