Sleep when you can, where you can

Sgt. Ryan Blount, 27th Brigade, New York Army National Guard, rests in a hallway after a full day of field training, before heading back out Jan. 16, 2015, at Alexandria International Airport, La. The exercise was an eight-day combined military training event designed to prepare Airmen and soldiers to respond to worldwide crises and contingencies. People can lessen the effects of sleep deprivation during long operations by taking precautions such as allowing Soldiers seven to nine hours of sleep regularly for five to seven days before the mission and allowing Soldiers to sleep who are not mission essential at the moment, according to Col. Vincent Mysliwiec, a sleep medicine specialist with 121st Combat Support Hospital, Brian Allgood Army Community Hospital in Yongsan, South Korea.
