| Popis: | A survey was distributed to about 25,000 truck drivers in the United States and Canada to determine their knowledge of several fatigue-related topics; 4,833 responses were received and tabulated. Analysis by topic area indicated that the following topics are not well understood by respondents and should be considered for special emphasis in fatigue outreach and education programs. Sleep disorders, especially sleep apnea, appear to be poorly understood by the respondents, and younger drivers are least informed on this topic. Many respondents are not aware that apnea is treatable. Napping is recognized as an effective short-term countermeasure to fatigue by fewer drivers than might be desired. Those who do use napping as a fatigue countermeasure believe it is very helpful. Sleep requirements may be underestimated by many drivers. About 25 percent of the respondents believe that 5 to 6 hr of sleep per night is enough to maintain alertness. Circadian rhythm effects are not fully understood by the respondents, especially effects on mood and performance efficiency. Caffeine and its effects on the body are misunderstood by many drivers. A fairly large proportion of respondents appear unaware of the limitations on caffeine’s stimulant effects and of possible side effects of caffeine overuse. Melatonin, a hormone, may be another substance the drivers need to know more about. Many drivers did not respond to the item on melatonin safety, and many others responded incorrectly. |
