Effects of Sleep Deprivation on the Brain

Sleep deprivation is a commonplace occurrence in modern culture and is increasingly being recognized as a significant public health issue. Yet a lot of people do not realize how important sleep is to their health.

Without enough sleep, the brain’s frontal lobes (which are responsible for the ability to pay attention, and make good judgments) do not function properly. When you are overtired, there is less blood flow to the frontal lobes and other parts of your brain. Brainwave activity throughout the brain is slowed, overworked neurons do not receive or coordinate information effectively, memory is impaired, and attention and focus are decreased. The result is a compromised ability to respond  appropriately to everyday life events as well as potentially dangerous situations.

Sleep deprivation distresses the brain in numerous ways that can impair judgment, slow reaction times, and increase “zoning out” during repetitive tasks.

The fact is, sleep is necessary for the nervous system to work properly and to help regenerate the body and the brain. Sleep deprivation leads to a range of attention and emotional deficits, including impaired memory, irritability, and decreased ability to concentrate on attention demanding task.
