Wake Up to the Workplace Effects
of Sleep Disordered Breathing
|
We've all fallen victim to it at some point in our lives, but do we really understand the impact fatigue can have on our bodies and even those around us? Fatigue is a state of feeling tired, weary or sleepy from insufficient sleep, prolonged mental or physical work, or extended periods of stress or anxiety. Fatigue can be described as either acute or chronic. Acute fatigue results from short-term sleep loss or heavy physical or mental work. Effects of acute fatigue are short in duration and reversed by sleep and relaxation. Chronic fatigue, on the other hand, is the constant state of tiredness not relieved by rest. Symptoms are similar to the flu, last longer than 6 months and interfere with certain activities. Both types of fatigue can stem from the way we carry out our daily activities, including our jobs, and increase the risk of workplace injuries. Work-related fatigue can be caused by: |
Did You Know?

Long work hours
Long hours of physical or mental activity
Insufficient break time between shifts
Inadequate rest
Excessive stress
Unfortunately, there are conditions that can increase the negative effect of normal stress and fatigue from daily activities, causing health problems and a lower quality of life. One such condition is sleep disordered breathing.
What is Sleep Disordered Breathing?
Sleep-Disordered breathing (SDB) describes a group of disorders characterized by abnormalities of respiratory pattern (pauses in breathing) or the quantity of ventilation during sleep. Obstructive sleep apnea (OSA), the most common such disorder, occurs when the airway is blocked when the muscles of the upper airway relax during sleep, causing breathing to stop often for more than 10 seconds. This occurs repeatedly during sleep.
Signs and symptoms of sleep apnea may include:
Excessive daytime sleepiness
Morning headaches
Memory or learning problems
Chronic snoring
Coughing/Dry throat
Frequent urination during the night
Falling asleep while at work, sitting quietly, on the phone, or driving
Memory or learning problems
Mood swings
Motor Vehicle Crashes
Its no secret that workplace fatigue can be a contributing factor to serious car crashes. In fact, 20% of serious vehicle accidents are linked to driver sleepiness. Driving while tired or fatigued is similar in magnitude to driving while under the influence of alcohol.
The most common reasons for car crashes caused by a driver who has fallen asleep are:
Working multiple jobs
Night shift work
Sleep duration of less than 5 hours per night
How to Combat Fatigue at Work
Practice good sleep hygiene. Adults should sleep 7-9 hours each day
Ensure work environment is conducive to productivity – good lighting, comfortable temperatures, reasonable noise levels, etc
Drink caffeine
Eat well. A small healthy snack during work breaks will keep your body going.

Sometimes, it isn't easy to admit you need help, but when your quality of life is at stake, it's important to take that first step towards understanding obstructive sleep apnea (OSA).
