To provide 24-hour access to emergency services, firefighters work a non-traditional schedule. With frequent changes to sleep location and routine, interruptions to normal sleep, and high levels of work stress, your sleep quality and quantity suffer significantly. Sleep quality affects your physical and mental health and overall vitality. Chronic poor sleep is linked to heart disease, diabetes, and reduced lifespan. Poor-quality sleep also affects safety and performance at work and while driving, putting you and others at risk. Given sleep’s importance to health and well-being, lifestyle changes and strategies may help improve sleep quality and quantity.
Sleep’s impact on our health and safety highlights the value of good sleep. Short-term sleep deprivation slows processing and reaction time, reducing your ability to adapt to sudden changes. Lack of sleep also reduces sustained attention, further increasing accident risk. These effects increase work-related accidents and injuries, putting you, coworkers, and the people you serve at risk.
Vehicle accidents are among the greatest safety risks from sleep loss. The AAA Foundation for Traffic Safety estimates drowsy driving contributes to 7% of all crashes requiring towing, 13% of crashes requiring hospital admission, and 16-21% of fatal crashes.
When compared to drivers who had slept for seven or more hours in the past 24 hours, drivers who reported sleeping six to seven hours had 1.3 times the crash rate, five to six hours had 1.9 times the crash rate, four to five hours had 4.3 times the crash rate, and less than four hours had 11.5 times the crash rate.
Driving and Sleep Deprivation
The National Highway Traffic Safety Administration estimates that four to five hours of sleep carries crash risk similar to driving with a blood alcohol concentration (BAC) equal to or slightly over the legal limit (0.08). Similarly, sleeping less than four hours is comparable to a BAC of roughly 0.12-0.15.
No matter what vehicle you’re driving or where you’re headed, all drivers must understand sleep deprivation’s impact on safe driving to prevent accidents and protect others on the road.
Do you struggle to fall asleep or stay asleep? Insomnia is a sleep disorder affecting up to 10% of the world’s population. In firefighters, multiple studies have reported that more than 50% of firefighters surveyed had clinical insomnia symptoms. Symptoms include trouble falling asleep, staying asleep, and waking early without being able to fall back asleep. Over time, this significantly affects memory, coordination, response time, mood, and other processes. Chronic poor sleep also increases your risk of depression, anxiety, high blood pressure, stroke, heart attack, sleep apnea, type 2 diabetes, and obesity. Managing insomnia is essential for protecting your overall health.
Build Better Sleep Habits
How can you improve your sleep? First, try to maintain a regular and consistent sleep schedule when you can. While shift changes can make this challenging, keeping a regular bedtime and wake time off-shift can help anchor your circadian rhythm.
Second, regardless of where you’re sleeping, try to create a consistent bedtime routine. Simple tasks like washing your face and brushing your teeth signal to your body and brain that it’s time to rest. Consider activities like reading, stretching, or listening to music before bed.
Third, avoid electronic devices such as tablets, laptops, and cell phones for at least 30-60 minutes before bed. These devices can overstimulate the brain and hinder melatonin production, a hormone that helps drive sleep.
Fourth, consider how your daytime activities may affect your sleep. Prioritize getting enough sunlight during your waking hours to support your circadian rhythm. Add physical activity and regular exercise to your day to promote rest later.
Relaxation Techniques for Better Rest
Finally, avoid excessive caffeine, especially later in the day, as it can reduce sleep quality. Small adjustments to your nighttime routine and daily activities can improve overall sleep quality.
Still feeling restless? Being constantly available and waiting for calls can leave you on edge. Meditation and relaxation techniques, such as box breathing and progressive relaxation, can help calm your brain and body.
To perform box breathing, lie comfortably in bed. Take a deep breath through your nose for a count of four, hold for four, exhale through your mouth for four, and hold for four. Repeat this cycle for several minutes, focusing on your breath. If counting to four feels short or easy, increase the count.
Progressive relaxation involves tensing a muscle group or body part for five to 10 seconds, then relaxing it as you exhale. Rest and breathe softly for 10-20 seconds, then repeat the process with different muscle groups throughout your body.
Ultimately, understanding the importance of sleep and adopting practical strategies can greatly improve your rest, supporting your overall health and safety. While not every sleep adjustment can be adapted to the station, making small, consistent changes to your daily habits, bedtime routine, and sleep environment can help support your body’s natural rhythms.
