These are through the use of barbiturates, benzodiazepines, and benzodiazepine receptor agonists. Barbiturates are not considered to be a primary source of treatment due to the fact that they have a low therapeutic index, while melatonin agonists are shown to have a higher therapeutic index. Military training
Sleep deprivation has been used by the military in training programs to prepare personnel combat experiences when proper sleep schedules arent realistic. Sleep deprivation is used to create a different time schedule pattern that is beyond a typical 24 hour day. Sleep deprivation is pivotal in training games such as "Keep in Memory" exercises where personnel practice memorizing everything they can while under intense stress physically and mentally and being able to describe in as much detail as they can remember of what they remember seeing days later. Sleep deprivation is used in training to create soldiers who are used to only going off of a few hours or minutes of sleep randomly when available. Changes in American sleep habits
