Recent data has shown that depression can be caused by lack of sleep and not the other way around. The amygdala in the brain, a structure that controls emotions, has been shown to be more responsive when subjects lack sleep and are given negative images, indicating that people who are sleep-deprived are less able to control their emotions. People with insomnia and depression can cure both by trying to keep consistent wake times and other tools to improve sleep.
- It has been found that if you have insomnia, you will have a greater chance of experiencing depression.
- As we have all seen from children who lack sleep, it is more difficult to control emotions when you are sleep-deprived or have slept poorly. So it is more difficult to fight emotions like depression.
- Based on research, the bottom line is that sleep is important, so you need to make sleep a priority.
"The possibility that depression leads to insomnia is also consistent with research in which I have been involved – where we found that adults with insomnia were more likely than others to have experienced anxiety and depression earlier in life."
