Sleep is a necessity for everyone, but it is especially important for those with physically demanding lifestyles, such as athletes and service members. Soldiers need at least seven hours of sleep, the same as everyone else, but they often get much less. This can have serious consequences, as sleep deprivation leads to slower reflexes, lower cognitive function, impaired concentration, decreased motivation, and poor mood. In the U.S. military, 76% of service members regularly don't get the recommended minimum amount of sleep, and this has resulted in fatal accidents and hundreds of millions of dollars in damage to equipment. During training, soldiers may sleep fewer than five hours per night, and this number decreases to fewer than four hours per night during combat. The military has recognized the importance of sleep and has started to prioritize changing the culture around it, providing education and tips to service members about how to get better sleep.

Sleep deprivation in the military can lead to fatal accidents and damage to equipment
Sleep deprivation in the military can have severe consequences, including fatal accidents and damage to equipment. A well-rested soldier is essential to the success of a mission and national security. Studies indicate that when soldiers get less than four hours of sleep per night, their effectiveness in combat is reduced by 15% to 25%. Sleep-deprived soldiers may experience impaired concentration and focus, decreased motivation, poor mood, and slower reaction times, which can threaten their personal safety and that of their squad.
In recent years, the military has increased its focus on addressing sleep deprivation among service members. The Office of the Army Surgeon General recommends that soldiers sleep at least seven hours per night, with a minimum of four hours during field training exercises. However, due to the demanding nature of military service, it is challenging for soldiers to get uninterrupted sleep, and they often have to nap when they can. The conditions of military service often make good sleep hard to come by, and short sleep becomes normalized, leading to negative health and performance impacts.
The Department of Defense (DOD) has found that the majority of service members sleep six or fewer hours a night, with deployed soldiers getting even less sleep. This lack of sleep has led to fatal accidents and hundreds of millions of dollars in damage to ships, vehicles, and aircraft. For example, fatigue was a contributing factor in the 2017 fatal ship collisions that resulted in the deaths of 17 sailors and extensive damage to two destroyers.
The military has implemented various measures to combat fatigue, including research, training, and awareness campaigns. However, more needs to be done to address the factors causing sleep deprivation, such as staffing shortages and workload. Leaders must also monitor and assess the effectiveness of these measures in reducing fatigue among service members.

Soldiers need at least seven hours of sleep per night
While soldiers face numerous challenges in getting adequate rest, such as the stressful and dangerous nature of their work, comorbid conditions, jet lag, and military culture, the consequences of sleep deprivation can be dire. Studies indicate that when soldiers get fewer than four hours of sleep per night, their effectiveness in combat decreases by 15% to 25%. Additionally, sleep deprivation can lead to slower reflexes, lower cognitive function, impaired concentration, decreased motivation, and poor mood.
The Department of Defense (DoD) has recognized the importance of sleep and has implemented measures to address fatigue among service members. The DoD recommends that soldiers sleep for seven or more hours per night, and during field training exercises, a minimum of four hours is required. To prepare for situations where sleep may be scarce, soldiers are advised to get at least nine hours of sleep beforehand. "Banking" sleep in this way can improve alertness and performance during short periods of sleep deprivation.
Furthermore, the military has increased its focus on educating service members about sleep and providing tips for better sleep hygiene. The Army's FM 7-22 Holistic Health and Fitness manual offers guidance on maintaining a consistent sleep schedule, finding a restful sleep environment, and adopting a bedtime routine. It also recommends taking short daytime naps to help soldiers achieve seven or eight hours of sleep over a 24-hour period. Leaders are expected to provide quiet and restful sleep environments and enable their soldiers to receive eight hours of sleep whenever feasible.

Military culture often accepts sleep deprivation as a normal part of life on duty
The military's demanding nature, including the stressful and dangerous nature of deployment and training, contributes to sleep deprivation among service members. During training, it is common for individuals to sleep fewer than five hours per night, often split into multiple episodes of sleep. Even on weekends, when they are encouraged to sleep more, they still get less than the recommended seven hours for adults. This pattern of sleep deprivation continues during deployment, with service members sleeping fewer than six hours per night on average.
The impact of sleep deprivation on soldiers' health and performance is significant. Studies indicate that when soldiers get fewer than four hours of sleep per night, their effectiveness in combat decreases by 15% to 25%. Sleep deprivation also leads to lower testosterone levels, impairing muscle repair and recovery. Additionally, it causes impaired concentration and focus, decreased motivation, poor mood, irritability, and longer reaction times, all of which can threaten a soldier's safety and the success of their mission.
Recognizing the importance of sleep, the military has taken steps to address fatigue and improve sleep habits among service members. The Army's FM 7-22 Holistic Health and Fitness manual offers guidance on sleep and promotes better sleep hygiene practices. The Department of Defense also recommends that soldiers bank sleep before anticipated sleep deprivation and take tactical naps during operations. However, despite these efforts, the military culture's perception of sleep deprivation as a normal part of life on duty persists.

Sleep deprivation can negatively impact a soldier's performance and personal safety
Sleep deprivation can have a detrimental impact on a soldier's performance and personal safety. Studies indicate that when soldiers get fewer than four hours of sleep per night, their effectiveness in combat is reduced by 15% to 25%. Soldiers who are sleep-deprived may experience slower reflexes and responses, impaired cognitive function, and difficulty focusing, which can lead to accidents, injuries, and even fatal mistakes.
For example, in the Navy, fatigue was found to be a contributing factor in fatal ship collisions that resulted in the deaths of sailors and significant damage to destroyers. Soldiers who are sleep-deprived may also exhibit risk-taking behaviours that can damage expensive equipment.
Additionally, sleep deprivation can negatively impact a soldier's health. Studies of Army Rangers show that sleep loss leads to lower testosterone levels, which are crucial for muscle repair and recovery. Sleep-deprived soldiers are also more likely to develop chronic health conditions like PTSD, diabetes, dementia, and cardiovascular disease. They may also experience mental health issues such as depression, panic syndrome, and increased risk of suicide attempts.
Furthermore, sleep deprivation can affect a soldier's ability to assess threats, coordinate with their unit, and engage optimally in combat. It can cause lapses in memory or attention, increasing the likelihood of accidents or injuries.
To mitigate the negative impacts of sleep deprivation, the military has implemented various strategies. These include conducting research to understand and address the causes of fatigue, providing education and training to service members on sleep hygiene and recognition of fatigue, and updating policies to prioritize sleep as a necessity. However, more needs to be done to address the underlying factors contributing to sleep deprivation among soldiers.

The military has implemented training to help service members recognise the signs of fatigue
Sleep is a critical component of a soldier's day-to-day performance and future mental and physical health. The military has implemented training to help service members recognise the signs of fatigue. This includes educating them about how sleep works and offering tips for better sleep. For instance, the 2020 update of the Army's FM 7-22 Holistic Health and Fitness manual includes expanded guidance on sleep and the promotion of better sleep hygiene. The manual recommends that soldiers follow a consistent sleep schedule, find a restful sleep environment, and adopt a bedtime routine. It also suggests taking short, daytime naps during the afternoon to help achieve seven or eight hours of sleep over a 24-hour period.
Additionally, the Department of Defense (DOD) has conducted research to identify the causes of fatigue and address them. They have also implemented training and awareness campaigns to help service members recognise and prevent fatigue. The DOD has updated its policies to emphasise the importance of sleep, signalling that leadership views sleep as a necessity rather than a luxury. These efforts reflect a growing awareness of the impact of sleep deprivation on military readiness and performance.
Despite these initiatives, there are still challenges in ensuring adequate sleep for service members. The conditions of military service, such as abnormal lighting, night shifts, and the requirement to grab sleep whenever possible, can disrupt sleep schedules and lead to negative health and performance consequences.
Furthermore, the military culture often accepts sleep deprivation as an inevitable part of life on duty. According to a 2021 Department of Defense report, military members feel they can control their sleep needs and perceive needing sleep as a sign of weakness. This mindset, combined with the physical demands and stressors of military life, contributes to the high rate of sleep deprivation among service members.
