Study Notes
Fatigue Training
- Sleep is crucial for safety.
- Fatigue is a serious concern.
- Fatigue can lead to dangerous situations.
What is Fatigue?
- Job demands
- Life demands outside of work
- Human biology
- Sleepiness
- "Don't care" attitude
- Irritability
- Forgetfulness
- Slow reactions
- Difficulty concentrating
Fatigue Facts
- 15 people die daily in truck crashes related to fatigue.
- Truck drivers have a higher fatality rate than other workers.
- A jet airliner crashes weekly due to the equivalent number of highway fatalities.
- 24 hours without sleep is equal to a 0.10 BAC
- Lack of sleep is the primary cause of driver fatigue.
Driving Without Awareness (DWA)
- DWA is viewed like drunk driving.
- Rising number of lawsuits involving fatigue.
- California and Arizona are leading the way in prosecuting DWA.
- It's likely other states will follow suit.
Consequences of DWA
- Impacts life and health
- Loss of freedom
- Hardship for family/loved ones
- Civil penalties
- Criminal penalties
- Attorney fees
- Lawsuits
What Happens When We Sleep?
-
Non-REM sleep: Deep sleep, slow heart rate, slow breathing, disorientation if woken up
-
REM sleep: Dream state, rapid brain activity, uneven heart rate, uneven breathing, twitching, paralysis
-
Both types of sleep are necessary for rest and refreshment.
How Much Sleep Do We Get?
- 65% lose sleep due to stress.
- 32% lose sleep at least once a week.
- 16% experience stress-induced insomnia.
How Much Sleep Do We Need?
- The average person needs 7-8 hours per night.
- Individual sleep requirements vary
What Keeps Us Awake?
- 2% blamed current events.
- 16% due to personal financial worries.
- 23% due to family issues.
How to Get a Good Night's Sleep
- Maintain a consistent bed and wake schedule
- Establish a bedtime routine
- Create a calming sleep environment
- Remove distractions like TVs/computers
- Eat and exercise several hours before bed
- Avoid stimulants before bed (like alcohol, caffeine, and nicotine)
Lack of Sleep Leads To...
- Trouble paying attention
- Slower reaction times
- Slower thinking
- Declining driving ability
- Health problems
Sleep Loss and Driving
- Factors predicting fatigue-related accidents
- Duration of last sleep period
- Amount of sleep in the last 24 hours
- Sleep quality
- Split sleep
Fatigue and Driving (Day vs Night)
- Increased risks at night include greater sleepiness, slower speed/erratic driving, and erratic lane position
- Accident risks are 3 times higher between 3-5pm due to higher core temps, high sleepiness, and difficulty staying focused
- Not getting enough 8hrs off-duty will lead to inadequate rest
- Sleepiness results in overestimating alertness, poor judgment, and decreased motivation.
Ways to Improve Fatigue Management
-
Naps: Short naps (less than 40 minutes) improve functioning but exceeding this can lead to sleep inertia, longer naps(2-3hrs) impact REM/Non-REM sleep and its restorative processes. Sleep is better than nothing.
-
Good Sleep: Dark, quiet, cool room; comfortable surface; regular exercise; balanced diet; warm shower/bath before bed; avoid caffeine/alcohol before bed.
-
Strike a Balance: Schedule time with loved ones; adjust activities around sleep schedules; sometimes important to miss functions.
Getting Enough Sleep
- Days Off: Maximize sleep
- While on Shift: Be mindful of caffeine intake
- Trust Your Body: Pay attention to sleepiness and follow your body’s cues. If you can’t return to sleep within 30mins, get up
Remember!
- Fatigue stems from biological causes
- Sleep loss debt accumulates over time
- Sleepiness cannot be ignored
- 2 full nights of good sleep are needed to recover
- Our internal clock dictates sleep patterns and doesn't adapt to night work
- Finding solutions to fatigue requires understanding its underlying causes without single-cause answers.
- Sleep improvement is possible.
Sleep Apnea and Driving
- Sleep apnea is a condition causing narrowing of the upper airway disrupting sleep.
- FMCSA and UPenn studies link severe sleep apnea to truck accidents.
What is Sleep Apnea?
- Upper airway closure during sleep that causes repeated breathing disturbances, complete awakenings
- Leading to poor sleep quality and daytime sleepiness
What are the Facts?
- An estimated 12 million Americans suffer from sleep apnea.
- Risk factors include being male, older than 40, and overweight.
- Untreated sleep apnea can lead to; high blood pressure, memory problems, weight gain, headaches, lower job performance, car/truck accidents, and daytime tiredness.
Types of Sleep Apnea
- Obstructive: Soft tissue in the throat relaxes and blocks airway
- Central: Brain doesn't signal muscles to breathe
- Mixed: A combination of both
Warning Signs of Sleep Apnea
- Snoring
- Pauses in breathing or gasping for air during sleep
- Daytime sleepiness
- Inability to concentrate
- Morning headaches/sinus congestion
- Falling asleep at work
- Depression
What to Do
- If symptoms occur, talk to a doctor.
- Sleep apnea must be properly diagnosed before treatment begins.
- Consult a sleep specialist if indicated.
- Accredited sleep medicine labs can identify and treat diagnosed patients
Conclusion
- Personal responsibility lies in maintaining sleep discipline
- Engage in regular exercise
- Maintain healthy eating habits.
- Seek medical advice if sleep problems or suspect sleep apnea
- Getting adequate rest is crucial for safety.
