A lack of sleep can lead to a number of side effects, such as depression and anxiety. These are just the physical symptoms. The mental effects of sleep deprivation are even worse. A person without enough sleep is likely to be irritable and have trouble concentrating on tasks. The brain needs rest in order to function properly, and without enough sleep, it cannot function as well as it should. Sleep deprivation can lead to a number of health problems, including heart disease and diabetes. A lack of sleep also increases the risk of accidents at work or on the road because it lowers reaction time and slows down motor skills.

It is said that sleep lessness or not getting enough sleep can affect your neurology, which in turn can affect your mood, memory, and concentration. There are many reasons why a person is not having proper sleep.
