Sleep Hygiene for First Responders and Military Service Members: Why Rest Is Part of the Job

For first responders and military service members, sleep can feel less like a necessity and more like a luxury. Long shifts, overnight calls, rotating schedules, deployments, training, alarms, unpredictable work demands, and exposure to traumatic events can make it difficult to simply turn your brain off at the end of the day. For some, sleep becomes something to squeeze in whenever there is an opportunity rather than something intentionally protected.

For people whose jobs require them to stay alert, make quick decisions, manage intense situations, and sometimes put their lives on the line, adequate sleep is especially important. Unfortunately, the demands of the job can make healthy sleep difficult to achieve.

Why Sleep Can Be So Difficult for First Responders and Military Personnel

First responders and military personnel often live in environments that are almost designed to disrupt normal sleep patterns. Firefighters, police officers, EMTs, paramedics, and other emergency personnel may work overnight or rotating shifts. You may go from sleeping during the night to sleeping during the day, sometimes repeatedly. Even when you technically have time to sleep, your body's internal clock may not cooperate. Military service presents many of the same challenges. Training schedules, overnight duties, deployments, travel across time zones, shared sleeping environments, and changing operational demands can all interfere with consistent sleep.

Then there is the nervous system.

After responding to emergencies, combat situations, accidents, deaths, injuries, or other traumatic events, your brain may not immediately recognize that the danger has passed. You may physically be home, but your nervous system may still be operating as though it needs to remain alert. That can look like lying in bed exhausted but unable to fall asleep, waking repeatedly throughout the night, having nightmares, waking up at the slightest noise, or feeling uncomfortable when you are not actively doing something. For some people, nighttime can actually become the hardest part of the day.

Sleep Hygiene Is a Starting Point, Not the Whole Solution

Sleep hygiene refers to habits and environmental factors that support healthy sleep. These include maintaining a consistent sleep routine when possible, creating a dark and quiet sleeping environment, being mindful of caffeine and alcohol, and developing a calming transition into bedtime.
These strategies are useful, but there is an important distinction: sleep hygiene alone is not considered an adequate treatment for chronic insomnia.

The 2025 VA/DoD Clinical Practice Guideline recommends against using sleep hygiene education as a stand-alone treatment for chronic insomnia and recommends Cognitive Behavioral Therapy for Insomnia, or CBT-I, as a primary behavioral treatment. This distinction matters, particularly for first responders and military personnel who may have tried all the usual advice and still find themselves staring at the ceiling at 2 a.m. Sometimes the problem is not simply that you need better sleep habits. Your brain and body may have learned patterns that are actively maintaining the insomnia.

Cognitive Behavioral Therapy for Insomnia (CBT-I) is a structured, evidence-based treatment specifically designed for people experiencing ongoing insomnia. Rather than simply giving you a list of things to do before bed, CBT-I looks at the thoughts, behaviors, and physiological patterns that may be keeping insomnia going. The VA describes CBT-I as the gold-standard treatment for insomnia.

CBT-I typically incorporates several strategies, including:

Stimulus control: Learning to strengthen the association between your bed and sleep rather than using your bed as a place to lie awake, worry, work, or mentally replay the day.

Sleep restriction or sleep-efficiency strategies: Working with a trained provider to adjust the amount and timing of time spent in bed so that your sleep becomes more consolidated. This should be done with appropriate clinical guidance rather than simply deciding to drastically reduce your sleep on your own.

Cognitive restructuring: Identifying unhelpful thoughts about sleep and challenging beliefs that may increase anxiety around bedtime. For example, thoughts such as "If I don't fall asleep right now, tomorrow is going to be a disaster" can create additional pressure that makes falling asleep even harder.

Relaxation and arousal-reduction techniques: Learning strategies that help your nervous system transition from a state of activation toward rest.

Sleep hygiene: Improving the environmental and behavioral habits that support sleep.

In other words, CBT-I goes beyond telling you to turn off your phone and drink less coffee. You do not have to wait until your sleep is completely falling apart before taking it seriously. Protecting your sleep does not make you less resilient. In many ways, it is one of the ways you maintain resilience. And if basic sleep hygiene is not enough, that does not mean you have failed at sleeping. It may mean you need a different approach. You spend your workday being prepared for the worst. And for people whose jobs require them to be ready for anything, taking care of your sleep may be one of the most important forms of readiness there is.
