Fatigue increases the risk of incidents because of the lack of alertness and ability to make decisions – slower reaction to signals and situations means a higher chance of something going wrong.
What can it look like?

Work now, sleep later. Right?
A sleep debt is the difference between a person’s required amount of sleep, and the actual amount of sleep obtained.
For example, if a person who requires eight hours of sleep only obtains six hours of sleep, then this person is deprived of two hours of sleep. If this occurs over four consecutive nights, the person will have accumulated an eight-hour sleep debt. Sleep debt leads to increased levels of fatigue, which as we know, can impair your alertness and performance.
Regular sleep habits help to build a good, strong sleep-wake pattern and keeps your management of fatigue in check.
