Here at Fleet Sheets® we understand the importance of sleep for health and general well-being at sea, but we’re not alone - it’s something that numerous medical studies have confirmed and the health risks of insufficient sleep may surprise you.
According to the National Heart, Lung and Blood Institute, “sleep play a vital role in good health and well-being throughout your life. Getting enough quality sleep at the right times can help protect your mental health, physical health, quality of life, and safety.” This is especially true for service men and women who work long hours and are resting in tight, unfamiliar quarters.
The Consequences of Insufficient Sleep on Your Health
According to the Division of Sleep Medicine at Harvard Medical School, most people don’t get enough sleep. While sleep deprivation is often accepted as a sort of badge of toughness among hard-working people within the military and at other physically demanding jobs around the world, the truth is that not staying rested poses serious short and long-term health risks.
According to Harvard Medical School, “in the short term, a lack of sleep can affect your judgment, mood, ability to learn and retain information, and may increase the risk of serious accidents and injury.” Researchers also caution that a prolonged time period of sleep deprivation can lead to more serious health concerns including “obesity, diabetes, cardiovascular disease, and even early mortality.”
While it can be easy to dismiss some of these sleep-related health issues (and the truth is that one night of missed sleep is not going to have many negative effects on your performance), sustained periods of insufficient rest can be a very real concern to those in the military.
Safety Implications of Sleep-Deprivation on Military Personnel
According to a study conducted by the Department of Operations Research at Naval Postgraduate School titled “The Role of Sleep in the Military: Implications for Training and Operational Effectiveness,” the impact of fatigue and the effects of sleep-deprivation on military personnel is a special case as “the combined effects of a multitude of acute and chronic stressors – including severe sleep restriction – make the military population both unique and relevant to study.”
This report goes on to cite numerous scientific studies which demonstrate the dramatic effect of sleep deprivation on human performance in a laboratory setting, but within the military “there is often a reluctance to accept such laboratory findings, asserting that motivation and determination will allow individuals to perform in real-world environments despite fatigue and lack of sleep.”
The truth is that the importance of sleep for health of military personnel is a real concern and mental and physical toughness isn’t enough to overcome it. The Naval postgraduate study cited above gathered information from 5758 participants in combat, naval operations conditions and training and educational environments around the globe. The observation of daily sleep duration for each operational condition is shown in the figure below:
For military personnel, the findings on total and uninterrupted hours of sleep may not come as a surprise, but the takeaway from this study is that the data clearly illustrates the sustained lack of uninterrupted sleep naval and coast guard personnel can expect while serving at sea.
This amount of daily rest is insufficient to sustain a safe level of mental, physical and emotional health over prolonged periods, according to most studies and most accepted research. Additionally, you put your body at risk of losing physical strength and conditioning without adequately rest.
Military.com states that “The best training plans will not work if sleep and nutrition are neglected. Without adequate sleep (eight hours a night), there is not enough rest for muscle cell growth and repair.”
