Yes, that’s true the retention of the things you have learned can only be effectively processed and used if you have adequate time for sleeping. No wonder, if you didn’t have much sleep, you can’t barely remember what lesson you had in your class yesterday. How is this so? Researchers say this is because lack of sleep can have a bad effect on your learning processes. The three learning processes are acquisition, consolidation and recall.
Acquisition is the process when actual information gets into the brain. Consolidation happens when the brain processes the information received so that the information becomes part of memory. Lastly, recall is the process of how the brain gets the stored information and make use of it. When a person lacks sleep, acquisition and recall are most heavily affected. Almost anybody can prove this theory. Try studying a lesson or two after a sleepless night. At the end of two hours, you may have read through the pages of the book but retention doesn’t come easily. It simply means the brain’s ability to get information has been temporarily impaired due to lack of sleep. Another significant impairment lack of sleep has is on consolidation.

When these same persons, had normal sleep, their emotions also went back to normal. There are also more long-term consequences of less sleep to a person’s mood and even psyche.
Studies show that there is a major link to lack of sleep and psychological problems such as anxiety, and depression. Many psychologists agree and found out that people who suffer from insomnia or chronic insomnia are likely to have major depression. The first symptom of depression is usually difficulty in sleeping.

In turn, anxiety causes agitation and arousal to increase which makes sleep for a person more difficult.
On the other hand, sleeping problems can also be genetic so it’s worth looking through the history of your family. A study from University of Pittsburgh suggests abnormal sleeping patterns of parents can be passed on to their children. Their children can have an increased risk of insomnia and increased risk of suicidal behavior as well. The teenagers of parents having sleep disorders in this research have been found to have two times more insomnia, fatigue, depression, anxiety and thoughts of suicide.
