The interaction between these two arousal dimensions results in different states i.e. calm energy, tense energy, calm tiredness and tense tiredness, having motivational implications.

Experts have shown that an extreme lack of sleep can cause a decrease in RNA functioning. This may cause genes to mutate and proteins to deform. The lack of sleep can also change patterns in the way the genes are activated and deactivated. This results in a disruption of the circadian clock. (Bradley,
The arousal theory says that people continue to do crime to try and maintain some sort of high. Some may commit criminal acts because they see it as a source of entertainment.

I. Introduction “Fatigue effects are closely related to the effects of sleep deprivation.

While sleep deprivation and stress can cause delay in productivity, poorer performance, and are experienced by everyone at least once in their lifetime, they are in fact very different.
