It is still not fully proved how sleep problem leads to depression.Lack of sleep reduces the hormone that helps many neurological functions. According to US national library of medicine national institute of health-Less sleep causes depression and psychological problems for many individual
So Chris did you sleep well at night? I was smiling trying to be cool, but truth is I was feeling helpless. I was standing in the class with a blank look. I could not respond to my professor’s question. He figured something out and asked me about my sleep deprivation pattern. I assume he knew less sleep causes depression and psychological problems, and wanted to warn me.
It happened to me many more time. Staying awake at night and snoring in class. I used to think it does not do material harm to me. However when I was researching on the reasons behind depression and mood swings; I found some interesting facts about sleep.
Insomnia and Depression
A survey says 15-20% insomniacs are later diagnosed with
depression.Also panic disorder test on 10000 adult shows that developing panic disorder is 20 times more likely among people who suffer from chronic insomnia or sleep deprivation.
How sleep problem leads to depression is still not fully proved. One fact is sure that depressed people sleep less or have more sleeping disorder. According to US national library of medicine national institute of health-
- 75% or more depressed people have insomnia symptom.
- 40% Young adult (aged less than 30) who suffer from depression also suffer from hyper insomnia.
- 10% Older patients (in 50s) who suffer from depression also suffer from hyper insomnia.
Lack of sleep is more common in Woman
Unfortunately women suffer from more sleep deprivation.This might be another reason why more woman suffer from mood swings and psychological disorders.According to the In The Great British Sleep Survey women has 10% less sleep score on an average.
Sleep disorder and quality of life
Sleeping disorder has a significant effect on a person’s quality of life.
UK conducted a questionnaire based survey to find out the effect of sleep deprivation on depressed people. Result on depressed people showed that sleepless nights can lead to a restless day and affect quality of life significantly.
This figure show people who lacked sleep last night faced difficulty in daytime .
This figure shows 98% responded felt that deprivation of sleep caused their quality of life.Only 2% said it had no impact.
Another UK based study in 2011 says on an average 50% of people has problem with sleep.Again in 2016 it was revealed 50% female population of UK are sleep deprived. In The Great British Sleep Survey of 11,129 regular adults, the result shows ‘Sound and adequate sleep’ is a very scarce item and lack of it causes pain in everyday life.
- Among the people who felt their sleep was not sufficient 75% was women.
- 55% were having difficulties in relationship because of it.
- 77% were having problems with concentration.
- 64% said it reduced their productivity.
- 83% had mood swings.
- 93% felt low in energy.
Sleep and memory
Did you ever go blank in an exam?It may have happened because of many reasons but science says it may be because you slept less than required.
Sleep promotes memory consolidation. In Alzheimer amyloid accumulates and the patient feel problem to fell asleep. Elderly people also face problem with remembering things.It is mostly attributed to their less sleep schedule.
Sleep in which we dream is called REM (Rapid Eye Movement) has a great impact in acquisition of objects which are emotionally charged and complex (declarative memory).Without such acquisition we can not remember our learned object.
Deep and sound sleep without dream is called SWS (Slow wave sleep). It also plays crucial role in building declarative memory. So if you are not sleeping enough, you are also risking the process of memory building and learning.
Sleep is scarce sleep is valuable as- Less sleep causes depression and psychological problems
Sleep is scarce and valuable.It totally fit in the definition of a commodity. Industry has recognized it, using it as a hot item. Personal fitness, activity, sleep tracking devices are much in demand today. These devices generated over 290 million dollars in 2015.Hotels are trying to make it easier for their guests to sleep well.Hotel offers better mattress,more pillows,soothing sounds, highly efficient sheets.Airlines are offering noise cancellation, flat bed seats, improved food that is digestive and easy for sleep.
I do not know how much all these are helpful when we have a problem inside. When we are over thinking about the day we just spent.When we are worrying too much about the next day or something in near future. When we are so busy and chronically sleep deprived we forget the magical impact of 10 minutes of peace and mindfulness.
