Getting a good night’s sleep doesn’t just affect your overall mood the following day, it also can improve your mental health. Sleep problems and mental disorders seem to have a cyclical relationship where they feed off of each other and can ultimately lead to a downwards spiral for both your sleep quality and your mental health. It’s important to treat both issues at the same time instead of only addressing one problem. Even if you’ve never had a mental health issue before, sleep problems can potentially cause people to develop anxiety and, in some cases, depression.
