Sleep & Mental Health


Effect of Sleep on Your Mental Health

When awake, your brain is busy handling the many functions of the human body, sleep rejuvenates the brain by clearing toxic waste proteins that accumulate between the brain cells that build up throughout the day. Studies on the relationship between the human brain and sleep show that lack of adequate slumber over time leads to a decline in the size of the brain. It is documented that poor quality of sleep can increase the rate of decline in brain volume over the span of 3-5 years. Any injuries to the brain are irreversible, so even sleep recovery of three days does not normalize the cognitive function of the brain. As one grows older, sleep deficiency can accelerate the age of the brain; reduce cognitive performance and increased brain-ventricle enlargement. These are prominent brain aging markers that one associates with the onset of the Alzheimer’s disease.

There is an intricate connection between sleep and your holistic mental health. So, how does sleep affects mental health? The people getting adequate sleep are found to have lower chances of developing mental illness. The ultradian rhythms of the body govern the appetite, hormone regulation, and temperature. Dopamine, the neurotransmitter secreted by the brain, regulates the rhythms so if there are disturbances in sleep patterns, this will interfere with the dopamine levels. Studies link such imbalances to schizophrenic and bipolar disorders.


Some conditions that show how sleep affects mental health

Sleep and Depression

Studies show that 90% of children and adults suffering from depression tend to suffer from sleep issues of some kind, with sleep apnea and insomnia being the most common influencer. Those suffering from insomnia have 4 times more likelihood of developing depression than those whose sleep is not disturbed?


Sleep and ADHD

Many people with ADHD also have complaints of sleep disturbances with sufferers experiencing difficult sleep that they describe as being in a state of wakefulness that leads to feeling tired and lethargic the next morning. Such people report symptoms such as lack of focus, distractibility and mood swings that can be related to their difficulties in falling and staying asleep, that prevent them from a restful deep sleep. This lack of deep sleep that regenerates and rejuvenates the brain, can eventually lead to sleep deprivation that can contribute to more serious physical and mental symptoms.


Sleep and Anxiety

Most people with an anxiety disorder tend to also have sleep issues, where a recurring pattern of feeling anxious makes falling or staying asleep difficult. Loss of quality rest time amplifies the anxiety symptoms, yet studies show that indicators of anxiety surface prior to sleep problems, unlike depression.


The Relationship between Mental and Physical Health

When you are not getting enough sleep it not only affects your mental well-being, it also has an influence on your physical well-being. Lack of sleep can make you feel lethargic where energy levels can consistently drop throughout the day and can even affect your appetite. Due to sleep deprivation, the body releases Ghrelin, a hunger hormone at higher amounts with lesser amounts of Leptin, a satiety hormone, thus your body starts to crave unhealthy foods. With the prolonged deprivation in restful slumber, your chances of weight gain and developing diabetes increases.

During sleep, the immune system makes antibodies and recharges your immune system, therefore obtaining less than 7 hours of sleep increases your chance by 2.94 times of developing a cold. When you are sick, the repressed immune system takes more time to fight the infection, so the recovery is slow. Sleep deprivation also has an influence on signs of aging, where people can experience things like puffy eyes and sallow skin after missing sleep for just a few nights. Chronic loss of sleep can also lead to the development of fine lines, dark circles, and lackluster skin. Having an undisturbed and peaceful night sleep will go a long way in helping rejuvenate your skin and retain that youthful glow.
