Stomach Sleepers Unwelcome In Navy: Here's Why

Sleep is a critical component of health, enabling the brain to focus, supporting immune function, and regulating hormones. However, for military personnel, achieving adequate sleep can be challenging due to various factors such as the stressful and dangerous nature of deployment and training, conditions like PTSD, jet lag, and the broader military culture. While the recommended minimum sleep for adults is seven hours, many service members, including those in the Navy, fall short of this, with an average sleep duration of 5.9 hours.

One aspect of sleep that is often overlooked is the sleeping position. Sleeping on the stomach, a preference for 16% of adults, has its pros and cons. On the positive side, it can prevent snoring and reduce mild sleep apnea symptoms by keeping the airways open. However, stomach sleeping also has several drawbacks. It strains the spine and back, aggravates neck pain, triggers discomfort during pregnancy, and can even cause facial wrinkles and breakouts due to the pressure on the face from pressing against the pillow.

Given the potential disadvantages of stomach sleeping, it is essential to explore alternative sleeping positions and techniques to ensure service members in the Navy can maximize their sleep quality and duration, contributing to their overall health and performance.

Sleep deprivation in the Navy is normalised in military culture and can be dangerous

Sleep deprivation in the Navy is a serious issue that has been normalised in military culture, often seen as a point of pride or a badge of honour. However, it poses significant risks to the health and safety of naval officers and can have dangerous consequences.

Historically, the military has viewed sleep as an impediment to readiness and performance, leading to a culture where sleep deprivation is normalised. This is exacerbated by the demanding nature of military service, including deployment, training, and the stress and dangers associated with combat. As a result, sleep deprivation is common among naval officers, with 76% of military personnel reporting insufficient sleep, significantly higher than the general population.

The consequences of sleep deprivation can be severe. Studies have shown that a lack of sleep impairs naval officers' ability to anticipate moral and tactical problems, increasing the risk of accidents and fatal errors. It negatively impacts concentration, focus, motivation, mood, and reaction time, all of which are critical to effective military operations. Sleep deprivation has also been linked to chronic health conditions such as PTSD, diabetes, dementia, and cardiovascular disease.

Recognising the dangers of sleep deprivation, the Navy has recently shifted its approach, prioritising adequate rest for sailors. New sleep guidelines have been implemented, instructing commanders to schedule watches based on circadian rhythms and minimising disruptions to sleep. The Navy is also exploring the use of technology, such as wearable sleep trackers, and employing "sleep trainers" to improve sleep habits and ensure sailors get the rest they need.

These efforts reflect a growing understanding of the importance of sleep and a commitment to addressing the normalisation of sleep deprivation within the military. By prioritising sleep and making cultural changes, the Navy aims to improve the health and performance of its personnel while reducing the risk of accidents and errors caused by fatigue.

The stressful and dangerous nature of deployment and training can lead to a lack of sleep

Sleep is an essential component of a healthy lifestyle, and this is especially true for those serving in the military. Unfortunately, due to the stressful and dangerous nature of deployment and training, service members often find themselves sleep-deprived. This can have significant negative consequences for their health, performance, and safety.

The demanding physical nature of military service means that soldiers require adequate sleep to support their bodies' recovery and repair. Studies indicate that when soldiers get fewer than four hours of sleep per night, their effectiveness in combat decreases by 15% to 25%. Furthermore, a lack of sleep can lead to lower testosterone levels, which are essential for muscle repair and recovery.

The impact of sleep deprivation goes beyond physical health. Soldiers experiencing sleep deprivation may also face impaired concentration and focus, decreased motivation, poor mood, irritability, and longer reaction times. These effects can threaten not only their personal safety but also the success of their missions and national security.

The stressful and dangerous nature of military life can also contribute to the development of sleep disorders. Insomnia and obstructive sleep apnea (OSA) are two conditions that have been observed at higher rates among service members. Insomnia is linked to post-traumatic stress disorder (PTSD), depression, and mild traumatic brain injury (mTBI), all of which are common in military personnel. OSA, which causes lower sleep quality and snoring or choking sounds during sleep, is also more prevalent among physically fit and younger service members.

The challenges of military life, including the stressful and dangerous nature of deployment and training, contribute to a culture where short sleep is normalized. However, this normalization of sleep deprivation comes at a cost. Service members who consistently get fewer than seven hours of sleep per night, the recommended minimum for adults, put themselves at risk for chronic health conditions and decreased performance.

To mitigate the effects of sleep deprivation, the military has implemented strategies such as educating service members about sleep hygiene and offering tips for better sleep. The Army's FM 7-22 Holistic Health and Fitness manual emphasizes the importance of consistent sleep schedules, restful sleep environments, and bedtime routines. Additionally, the Department of Defense recommends "tactical naps" of 20 minutes followed by caffeine to improve alertness during operations requiring sleep deprivation.

While these strategies provide temporary solutions, addressing the underlying causes of sleep deprivation in the military is crucial. By recognizing the stressful and dangerous nature of deployment and training and its impact on sleep, the military can develop more effective interventions to ensure service members get the rest they need.

Soldiers often sleep in loud, uncomfortable environments, which can negatively impact sleep quality

The conditions of military service can make good sleep difficult to achieve. For example, soldiers may be exposed to abnormal lighting that disrupts their circadian rhythms. Those working in 24-hour environments are exposed to artificial light that reduces melatonin levels and sleep quality. If they wake up at night and need to use the bathroom, they may have to walk a significant distance outdoors in bright light, further disrupting their sleep.

Additionally, the noise of an engine room can increase cortisol (stress) levels, making it harder to fall asleep later. U.S. Navy sailors who work in dark control rooms may have significantly different melatonin levels than those who work outdoors due to differences in light exposure. Without access to natural sunlight, those working on submarines suffer from irregular sleep-wake cycles.

Military combat missions are often conducted at night, and service members may need to coordinate with units in different time zones, leading to sleep disruptions due to midnight teleconferences. As a result, soldiers may experience chronic sleep deprivation, which can have negative consequences for their health, performance, and safety.

Sleep disorders are common among service members, with insomnia and sleep apnea being prevalent

Sleep disorders are highly prevalent among service members, with insomnia and sleep apnea being the most common. In the past 15 years, rates of insomnia among service members have increased 45-fold, and obstructive sleep apnea (OSA) has increased 30-fold. Over half of active-duty military personnel suffer from OSA, and nearly one-third suffer from insomnia as well. These disorders are often linked to deployment and combat exposure, with deployed soldiers being more than twice as likely to be diagnosed with insomnia or OSA compared to their non-deployed counterparts.

The stressful and dangerous nature of military service, including frequent travel and irregular sleep schedules, contributes to the high prevalence of sleep disorders. During Operation Iraqi Freedom, the average U.S. Army soldier slept for only 5.8 hours per night, with similar trends observed in other branches of the military. Short sleep durations are normalized in the military, with 60% of service members sleeping fewer than six hours per night, and 76% not meeting the recommended minimum of seven hours.

Insomnia is characterized by difficulty falling or staying asleep and is often linked to post-traumatic stress disorder (PTSD), depression, and mild traumatic brain injury (mTBI). OSA, on the other hand, is a sleep-related breathing disorder that causes snoring, gasping, or choking sounds during sleep. Interestingly, OSA in service members tends to affect younger individuals with lower body weights and higher fitness levels compared to the general population.

The high rates of sleep disorders among service members have significant implications for their health and performance. Sleep deprivation can lead to impaired concentration, decreased motivation, irritability, and slower reaction times, all of which can impact a soldier's personal safety and the success of their missions. Additionally, sleep deprivation is linked to various chronic health conditions, including PTSD, diabetes, dementia, and cardiovascular disease.

Pregnancy can make sleeping on your stomach uncomfortable and harmful

While sleeping on your stomach during the early stages of pregnancy is considered safe, it may become uncomfortable as your pregnancy progresses. As your baby bump grows, you may find it challenging to sleep on your stomach due to the altered curvature of the spine, which can also cause neck and shoulder problems.

During the third trimester, sleeping on your stomach is very unlikely as your bump will be larger, and this position may no longer be comfortable. It is recommended that, during this stage, you sleep on your side, preferably the left side, to optimise blood flow to the fetus. Sleeping on your back during the third trimester may increase the risk of stillbirth and other complications.

Overall, while sleeping on your stomach during pregnancy is generally safe in the early stages, it may become uncomfortable as your bump grows, and it is important to switch to sleeping on your side during the third trimester for the optimal health of your baby.
