The Impact of Sleep Issues on Mental Health
We've all felt the grumpiness that usually follows a bad night's sleep. But the connection between sleep and mental health goes far beyond just feeling cranky.
When sleep issues disrupt your ability to get quality rest, it can affect how you think, feel, and cope with daily stress. In fact, long-term insomnia has been linked to an increased risk of depression, anxiety, and other mental health issues. Conversely, struggling with your mental health can often be the very thing that keeps you awake at night, creating a challenging cycle that can be difficult to break.
Take a closer look at the two-way relationship between sleep and mental health, and how it may affect your well-being.
