Key Takeaways
- Relationship Between Sleep and Mental Health: Sleep and mental health have a bidirectional relationship. Poor mental health can lead to sleep disturbances, while sleep problems can exacerbate mental health issues. Stress, anxiety, and depression can make it difficult to fall asleep, and a lack of sleep can worsen mood and emotional regulation.
- Common Conditions Linked to Sleep Problems: Several mental health conditions are linked to sleep problems. These include depression, anxiety disorders, bipolar disorder, seasonal affective disorder (SAD), attention deficit/hyperactivity disorder (ADHD), schizophrenia, obsessive-compulsive disorder (OCD), and autism spectrum disorder. These conditions can cause insomnia, hypersomnia, or other sleep disruptions.
- Importance of Treating Sleep and Mental Health Together: Improving sleep hygiene and seeking treatment for sleep disorders can have positive effects on mental health. Similarly, treating mental health conditions can lead to better sleep quality and overall mental well-being. Cognitive-behavioral therapy and establishing bedtime routines can help improve sleep and mental health simultaneously.
Staying mentally healthy and balanced has been linked to improve overall well-being. But keeping your mental health in check may actually help improve your quality of sleep. As decreased mental wellness has been linked to numerous sleeping troubles and disorders, the reverse may also be true.
And, the relationship may be reciprocal, meaning your quality of sleep can also impact your mental health. Thus, finding ways to keep stress low and maintaining healthy sleep hygiene are crucial to your overall well-being.
You’ve likely experienced this relationship firsthand, too. How many times have you woken up after a night of poor sleep only to find yourself in a poor mood, stressed, or even down? Likewise, you may have found yourself tossing and turning all night, unable to fall asleep fast because you’re worried about job pressure, family issues, or more. Mental health and sleep are intrinsically linked and when one is out of balance, the other often suffers.
“Our physiological and mental functions are regulated by the interaction between a sleep drive and a circadian process,” notes Dr. Nayantara Santhi. “Hence circadian rhythms play a critical role in our mental health. There is a reciprocal relationship between mood disorders and circadian rhythms.”
“Mood disorders are associated with disrupted circadian rhythms such as sleep and cortisol secretion. However, it is only recently that researchers have started to focus on the relationship between the circadian system and mood regulation.”
The Relationship Between Sleep and Mental Health
Why are sleep and mental health so closely linked? It can help by first understanding what happens to your body when you’re asleep.
There are four stages of sleep — three non-REM stages and one REM stage — which serve vital functions for your body and brain health. Not only does the overall activity in your brain during sleep help improve your cognitive function, memory, and ability to learn, but it also has been shown to have a positive impact on your emotional processing. In other words, restful sleep can boost your mental health.
One of the functions of sleep is to enhance your memories by helping to sift through and evaluate them. While healthy sleep has been shown to benefit your cognitive health, unhealthy sleep can lead to negative side effects.
In fact, poor sleep has been shown to influence your mood and overall emotional well-being — it’s also associated with mental health disorders and in extreme cases, has even been shown to lead to suicidal thoughts.
Mental Health Conditions Linked to Sleeping Problems
Poor sleep quality can impact your health overall. Worse, poor sleep can be both cause of and consequence of a mental health condition, potentially creating a vicious sleep of lost sleep. Here are a few common mental health diagnoses that have been linked to unhealthy sleep.
Depression

How to Improve Your Sleep and Mental Health
Whether you suffer from a diagnosed mental health disorder like depression or anxiety, or if you simply notice your mood deteriorates due to an inability to fall or remain asleep, here are some tips to help improve your sleep hygiene. Better quality of sleep may also lead to better mental health, after all.
Establish a Bedtime Routine
These aren’t just for children. A bedtime routine is important to help prepare your body for sleep. This can be particularly helpful if you find it difficult to fall asleep fast each night.
While most scientific studies incorporating bedtime routines focus on infants or young children, research indicates that establishing a nightly regime not only improves sleep, but it can improve your overall sleep health rather quickly.
If you don’t already have a set bedtime, try establishing one and aim to be in bed by that time each night. It’s important to pick a time that makes sense for your schedule and that you can stick to consistently — yes, even on weekends. Use a sleep calculator to help you if needed.
Creating an evening routine and doing the same things — brushing your teeth, unwinding, or even reading — right before bed can help your body prepare for sleep.
Invest in a High-Quality Mattress and Pillow
Sometimes the cause of not falling or staying asleep can be cured by simply trading in your existing mattress and pillow for better options. Back pain and sleeping disorders are closely linked, and alleviating triggers of back pain may be able to resolve or improve your sleep woes. Old mattresses have many health effects, including worsened back pain.
There’s not one solution to which type of mattress or pillow is right for everyone. Most people sleep better on different softness levels, which some preferring firm and others opting for soft. That noted, medium-firm mattresses are often identified as helpful for those with back trouble.
Changing your sleep position may also help. Sleeping on your side or stomach could cause spinal alignment issues, which lead to back pain, and promote waking up throughout the night.
Unplug from Electronics
Shut off electronics at least one hour before bed. While establishing a bedtime routine is key to improving sleep hygiene, this tip only works well if you’re also unplugging before going to bed. Disconnecting from screens is particularly important since many of us spend our entire days looking at them.
Exposure to light-emitting screens in the evenings has been found to disrupt the circadian rhythm, and cause sleeping issues for many Americans. While disconnecting completely in the evenings may not be possible, unplugging an hour or two before bed can help minimize blue light exposure.
Setting blue light filters on your phone in the evening may also be beneficial, particularly if you use apps for sleep. But try to make it a habit to put your phone away before bed — and try to avoid scrolling social media if you can’t fall asleep right away.
Consider Cognitive Behavioral Therapy
This valuable program may help sleep — and cognitive behavioral therapy Verified Source National Library of Medicine (NIH) World’s largest medical library, making biomedical data and information more accessible. View source is also used in the treatment of many mental health disorders. While treatment methods can vary and may be individualized, in general, this treatment focuses on identifying and rectifying behaviors that may worsen your sleep quality.
Cognitive therapy is often used to treat insomnia and other chronic sleeping disorders. If you’re interested in trying out this method, talk to your doctor to find out next steps.
