A recent study suggests that there might be a link between workload and sleep-related fatigue.Continue reading →
Whether people openly and freely report fatigue levels, fatigue risks or other critical information depends highly on an organization’s reporting culture.Continue reading →
For example, one study showed that introducing a sleep health training program and a sleep disorders screening opportunity netted 46% fewer disability days and 24% lower odds of filing an injury report in the training attendees versus non-attendees.Continue reading →
26% of all fatal and injury crashes are estimated to be related to fatigued driving and 167,000 Ontario drivers have been involved in at least one crash due to fatigued or drowsy driving.Continue reading →
If you reframe the problem as an opportunity, it gets really exciting. Instead of losing $80 million, look at it as an opportunity to make $80 million by addressing sleep-related fatigue issues.Continue reading →
A functional magnetic resonance imaging (fMRI) study showed that the amygdala’s reaction to negative emotional stimuli is greater in magnitude/intensity and volume in people who miss a night of sleep when compared to a control group. This study also showed that the connections between the amygdala and the MPFC were weaker in the sleep deprived group. This means that the amygdala’s reactions can’t be inhibited as well by the MPFC in people who lack sleep.Continue reading →
If you are developing a controlled rest procedure, here are 3 rules to keep in mind.
Rule 1: Some sleep is better than no sleep.
Rule 2: The second rule is that more sleep is always better.
Rule 3: The last rule is that sleep inertia needs to dissipate before a napper can be re-engaged in safety critical activities.
Fatigue countermeasures are strategies that can be used to fight fatigue that takes hold during duty. They should not be used routinely to keep pilots, mariners or train engineers and conductors alert and safe. Instead, fatigue prevention strategies should be the mainstay for alertness and safety. If people are routinely napping on the job, then they are too fatigued probably because the fatigue prevention strategies are failing.Continue reading →
Earlier this month the NTSB released an update into their investigation of the Airbus A320 that squeezed through a potential disaster by less than 59 feet. I finally found time to read through the update and it looks like the NTSB is sticking to their protocol of only releasing validated factual information. This is a good thing; it is still way too early to thoroughly identify all the causal factors. Plus, dropping hints at what they are considering would result in too much conjecture and a knee jerk reaction to stick together a patchwork of solutions.Continue reading →
On July 7, 2017 at 23:56 (San Francisco/Pacific Time) Air Canada flight ACA759 almost landed on a taxiway where four aircraft where waiting to take off. ACA759 missed the first aircraft by only 100 vertical feet. This could have been a terrible accident.Continue reading →
There is a hint in the report about how communication between the Medical Examiner and the pilot may have played a role in allowing a person with an untreated sleep disorder to continue to operate. The report said that the pilot with obstructive sleep apnea (OSA) did not report any daytime sleepiness to the doctor. There are two reasons why the sleepiness may not have been reported.Continue reading →
I would argue that it would not cost anywhere near $50,000 to identify the insufficient sleepers and provide a solution. An investment of $60.00 to reap a $50,952.39 return in only one year. That’s an 84,820.65% ROI that keeps paying year after year!Continue reading →

In a study of train operators they showed that fatigued operators use more heavy brake applications and less dynamic brake and throttle manipulations than alert operators. This style of train operation burns 9% more fuel and for one train route this resulted in $183,000 more fuel being burned annually by fatigued train operators than alert operators. Here’s the flip, by reducing fatigue you will improve operational efficiency and reduce fuel costs by 9%. This can put $183,000 back into your budget annually.Continue reading →
A much easier way to determine a person’s level of fatigue is to measure it indirectly through performance on a psychomotor vigilance task (PVT). PVT results are strongly correlated to fatigue risk factors such as acute and chronic sleep disruption, continuous wakefulness and circadian rhythm disruption.Continue reading →
There is a movement in fatigue research to use light in shorter bursts to temporarily relieve fatigue and improve performance without suppressing the melatonin. The strategy is called a fatigue countermeasure.Continue reading →
