If you followed me in the clinic, you would see how many of my patients with sleep apnea also have depression and anxiety. Why?
Poor sleep and depression are often linked in a vicious cycle with one affecting the other and vice versa.
Research has shown that poor sleep can contribute to the development of depression, and depression can also lead to poor sleep.
There are several reasons why poor sleep can cause depression.
1. Hormones!!!
Hormonal imbalance to be precise. Poor sleep can disrupt the balance of hormones in the body, including serotonin, which regulates mood and sleep, and cortisol, which regulates stress.
2. Inflammation
Chronic sleep disturbances have been linked to an increase in inflammation in the body which has been associated with the development of depression.
3. Cognitive impairment
Poor sleep can impair cognitive functioning, including memory, focus, and decision-making, all of which can lead to negative thoughts and feelings.
4. Decreased physical activity
People who suffer from poor sleep are often too tired to engage in physical activity, which is known to have a positive impact on mood and mental health.
5. Increased stress
People who struggle with sleep often experience increased stress and anxiety which can contribute to depression.
Poor sleep and depression are intertwined and can affect each other in multiple ways. By addressing sleep issues, people can reduce their risk of developing depression and improve their overall mental health and well-being.
