Hazard due to Fatigue

Do you know is the major cause
behind Ground/Air Accident/ Incident?
All working staff has to recognize when he / she is too tierd do sleep cycles dehydroation, nutrition and lines play in idenitifying and ewsponding to fatigue?

Sleep deprivation and overwork are largely responsible for unsafe working environment. That is the reason NAC, fight safety strongly recommends the concern to prove its practices to reduce fatigue and improve alertness. The NASA report contains 750 incident since 2003 in which aviation workers cited fatigue – related incidents. Some additio0nal Cades were found that aircraft incident/ accident happened due to pilot falling asleep, found by "USATODAY" pilot fatigue due to disrupted creation rhythm was cited as a contribution factor.
Sleep expert's say those swing shifts are especially difficult. Body has no time to adjust to a new sleep pattern . Insufficient sleep then impairs cognitive processes such as the data tracking and quick, accurate decision- making that pilots are called on to perform. Lack of sleep is a problem in many airlines, where new rules allow pilot to fly more hours in a shorter time frame- or for that matter, in any airlines where safety is an issue. Experts say that sleep-depraved people think they have airhostess to a lack of sleep, when in fact objective testing shows that their thinking abilities and reaction times have deteriorated, leading to more errors.
Sleep deprivation also is linked to depression, obesity, diabetes and high blood pressure. Sleepiness may seem like a mundane and therefore negligible issue. We have read the story of pilots filling asleep in the cockpit. The story may be just as "airborne legend", but true or not, pilot with a modicum of experience can deny having occasionally had to battle with fatigue or that it some how affected his or her performance. Thus, I'd like to share some information regarding Crew Duty time and Hazard of Fatigue.
