Their lives, as well as the lives of others, may depend on it. SEALs on missions must be able to operate efficiently, oblivious to subzero temperatures and their own physical comfort. This extreme training is critical, though. Only about 25 percent of SEAL candidates make it through Hell Week. Timed exercises, runs, and crawling through mud flats are interspersed throughout the five-and-a-half days. Pretty much every evolution during Hell Week involves the team (or boat crew) carrying their IBS- inflatable boat, small - over their heads. It gives a needed psychological boost to tired trainees, many of whom are nearly sleeping while they eat. Eating hot food is a substitute for being warm and dry. During Hell Week, trainees get four meals a day - sometimes MREs, but usually hot meals of unlimited quantities.

During this time, trainees face continuous training evolutions. Hell Week begins at midnight Sunday and ends Friday afternoon. This is when students train for five-and-a-half days with a maximum total of four hours of sleep. The fourth week of basic conditioning is known as Hell Week.
