Here is an interesting video here that shows the dog having the disorder of sleep particularly sleepwalking. I personally think this video is very interesting since it surprises us by showing that even animals undergo the disorder of sleep just like the humans do.
The disorders of sleep take various forms which are insomnia which is the most common, narcolepsy, sleep apnea, night terror, and sleep walking. When I thought of sleep, I considered it as resting. However, I found out that there are people who struggle falling asleep and staying asleep due to the disorders of sleep, and it was surprising to see how common they are. The textbook addresses that "30 to 50 percent of people" are involved in sleep problems. These problems are usually harmless but are indeed very distressful.
Have you ever deprived of few nights of sleep from load of work? I am sure many of you guys have experienced such stressful situation. However do you know that the few nights of sleep deprivation can lead to many negative consequences such as decrease in ability of daily functioning, depression, having trouble paying attention, and weight gain? I actually never thought that the absence of sleep can bring serious problems to both physical and mental states. Therefore, I think it is important for all of us to keep in mind that getting enough sleep is very essential for maintaining the health and daily routine.
