Lack of Sleep Equals Lack Of Mental Health

The Link Between Sleep and Mental Health in the Brain

Lack of Sleep Equals Lack Of Mental Health
World Economic Forum

Science and medicine are only at the start for understanding the genetic and biochemical basis Mental illness, a broad term used to define conditions such as anxiety, depression, and mood and psychotic disorders. It has become very important to find treatments for these conditions as millions of people from around the world are suffering from them. While several individuals seek a diagnosis from medicine, a large population of scientific evidence is suggesting the antidote lies in our most basic human functions: sleep.

Check out this detailed explanation by MIC:


Disrupted sleep such as insomnia can actually help us predict mental illness issues and fixing problems related to sleep can help treat them. Unfortunately, most clinics around the globe have been ignoring the effects of sleep on mental illness. Instead, drugs and medications are seen as the solution.

To understand the relationship between sleep and mental illness in the brain, we have to understand the biology of sleep and Circadian rhythms.

Circadian rhythms are innate and lie in the genomes of almost every living thing on the planet. As humans, our physiology is structured around our everyday cycle of activity and sleep. During the active phase, our organs need to be prepared for the intake, processing, and uptake of nutrients, as our energy use is high and food and water are consumed. During the sleep phase, however, even though the energy use and digestive processes decrease, important processes such as cellular repair, memory consolidation, toxin clearance, and information processing occur in the brain.

Issues in sleep such as jet-lag, insomnia, and shift-work disrupt the Circadian rhythms therefore messing with our ability to do the right thing at the right time. This can result in several health issues including some of the ones below:


Circadian rhythm disruption was noticed in 80% of patients with schizophrenia. Moreover, it has been recognized to be a factor for several mental issues. Surprisingly, sleep deprivation is largely ignored in the matter.

The circadian timing and sleep system is a result of interactions between several brain regions, hormones, and neurotransmitters. Because of this, irregularity in any of these neurotransmitter systems can have a great impact on both sleep and Circadian timing. With this information, it is easy to see why so many things are correlated to each other in the brain. Complex interactions between neurotransmitters and the overlapping of systems with each other in the brain lead to several illnesses, both mental and physical. It is a common fact that sleep disruptions happen before episodes of depression. Moreover, individuals recognized as "at risk" for bipolar disorder and child-onset schizophrenia at several times show problems with sleep before any clinical detection of an illness.

Right now, studies are being done to fix this problem. However, to take care of ourselves, maybe it's time to really focus on the 8-hours of sleep rule. Try not to pull all-nighters during the next semester of college. Maybe if you are on top of your game, both health and academic-wise, you won't be stressed or depressed. Some problems are preventable and I'm sure you all know the saying, "Prevention is better than cure."

Course registration at college can be a big hassle and is almost never talked about. Classes you want to take fill up before you get a chance to register. You might change your mind about a class you want to take and must struggle to find another class to fit in the same time period. You also have to make sure no classes clash by time. Like I said, it's a big hassle.

This semester, I was waitlisted for two classes. Most people in this situation, especially first years, freak out because they don't know what to do. Here is what you should do when this happens.

Ever since I could remember, it was a treat to receive Easter Bread made by my grandmother. We would only have it once a year and the wait was excruciating. Now that my grandmother has gotten older, she has stopped baking a lot of her recipes that require a lot of hand usage--her traditional Italian baking means no machines. So for the past few years, I have missed enjoying my Easter Bread.

Top 10 Reasons My School Rocks!

Why I Chose a Small School Over a Big University.

I was asked so many times why I wanted to go to a small school when a big university is so much better. Don't get me wrong, I'm sure a big university is great but I absolutely love going to a small school. I know that I miss out on big sporting events and having people actually know where it is. I can't even count how many times I've been asked where it is and I know they won't know so I just say "somewhere in the middle of Wisconsin." But, I get to know most people at my school and I know my professors very well. Not to mention, being able to walk to the other side of campus in 5 minutes at a casual walking pace. I am so happy I made the decision to go to school where I did. I love my school and these are just a few reasons why.
