There are some things that we just can’t do without, such as air, water and food (especially air!) but there something else that we have to have and that is sleep. Our bodies need to rest to recover our energy as well. In addition sleep also helps with our nervous system according to the National Institute of health.
“Too little sleep leaves us drowsy and unable to concentrate the next day. It also leads to impaired memory and physical performance and reduced ability to carry out math calculations. If sleep deprivation continues, hallucinations and mood swings may develop. Some experts believe sleep gives neurons used while we are awake a chance to shut down and repair themselves.”
Sleep deprivation can also have an effect on our immune system, which protects us from getting ill. While we sleep our bodies not only grow cells but repair them as well.
A recent study has also shown that sleep deprivation affects the immune system much as stress does. A study was done in the Netherlands and Britain where 15 young men had their blood count compared after normal and sleep deprived situations. The white blood cells were affected under the sleep deprivation similar to the condition of stress.
