Understanding the Link Between Sleep and Mental Health

June 20, 2024

Your mental health and getting enough sleep are important for how you feel and act every day. These factors essentially work together to make sure you're happy and healthy.


Your mental health affects how you interact with others, and getting enough sleep is crucial for your overall well-being. To make improvements in both areas, you must recognize how they are connected.


In our guide, we will look at the basic elements of sleep, how common mental health disorders are, and how sleep and mental health influence each other. 


Why is getting enough sleep important?


Getting a good night's sleep is essential for your health and well-being. It affects how you think, learn, and solve problems. Sleep also helps you regulate your emotions and handle stress better.


Not getting enough sleep can lead to serious health issues like obesity, diabetes, and high blood pressure. Therefore, you should make sleep a priority to improve your quality of life and overall health. 


Other benefits of quality sleep include:

  • Enhanced cognitive function 

  • Improved mood

  • Increased energy levels

  • Enhanced physical performance 

  • Better stress management

  • Balanced appetite throughout the day

  • Improved immune system

The relationship between sleep and your mental well-being


Lack of sleep can have many negative effects on your mental health. One of the biggest ones is how it may impact your mood. Not getting enough sleep can make you more irritable and may make it harder to regulate your emotions. On top of that, it can make symptoms of anxiety and depression worse. 


Not getting enough sleep can also affect how well your brain works. It can make it harder to remember things, concentrate, and make decisions. These types of issues may make you feel like you’re not good at anything and make you feel frustrated. 


The connection between sleep and mental health is intricate and has many layers. Neurotransmitters such as serotonin, dopamine, and GABA control both sleep patterns and mood. Imbalances in these neurotransmitter systems can lead to sleep problems and worsen your mental health issues.


Did you know the brain actually experiences neurobiological changes that can impact sleep and mental health? The functioning of the hypothalamic-pituitary-adrenal axis and the circadian rhythm system can change, which causes sleep disturbances and mood instability. 


Understanding sleep disorders


Sleep problems include different conditions that make it hard to sleep well. This can make it tough to fall asleep, stay asleep, or get the kind of sleep that helps you feel refreshed. There are a few common sleep problems that can affect your mental health:

 

Insomnia is a sleep disorder where falling asleep, staying asleep, or getting restful sleep is difficult. It leads to daytime tiredness, irritability, and difficulty concentrating. Chronic insomnia worsens mental health conditions like depression and anxiety, causing more stress and reducing life's enjoyment.


Sleep apnea is a condition that makes you stop breathing or take shallow breaths while you're sleeping. This disrupts your sleep patterns and makes you feel tired and worn out during the day. It can also affect your mental health, causing problems like feeling sad or worried. This might happen because your sleep keeps getting interrupted and your brain chemicals and body get are not balanced properly.

 

Narcolepsy is a brain condition that makes you feel sleepy during the day, and you might fall asleep suddenly without warning. It can impact your REM sleep and even make it hard to control your muscles. This condition can make you feel frustrated, embarrassed, and lonely because you can’t control it.


Restless legs syndrome makes your legs feel uncomfortable and makes you want to move them a lot, especially when it's bedtime. This can also make you feel groggy and have trouble thinking clearly. 


Parasomnias are sleep problems that cause atypical behaviours, movements, or unusual experiences during sleep. Examples include sleepwalking, nightmares, and acting out dreams during your sleep. These issues disrupt sleep patterns, which can lead to daytime fatigue and impact brain function. 


The effect on your mind changes based on how often it happens and how problematic it is, going from small annoyances to big problems in your daily routine.


Mental Health Disorders and Sleep


Sleep and mental health are closely linked, and when one is affected, it can make the other worse. Here are some mental health conditions and how they affect your sleep patterns:


  • Depression and sleep: Depression can significantly ruin your sleep patterns, causing either extreme difficulty in falling asleep or excessive sleeping. This can lead to heightened exhaustion and emotional fatigue. 

  • Anxiety disorders and sleep: Anxiety disorders make your mind race and cause you to wake up frequently throughout the night. It can also lead to scary dreams and sudden panic attacks while you're sleeping.

  • Bipolar disorder and sleep: Bipolar disorder makes people go through times of being really excited and really depressed. When they're excited, they might not need as much sleep, but when they're depressed, they might have trouble falling asleep or sleeping too much.

  • Post-traumatic stress disorder and sleep: PTSD makes it harder to sleep by giving you nightmares, making you super alert, and filling your head with unwanted thoughts. It can be tough to both fall asleep and stay asleep because of this. Sometimes, you might even have flashbacks while you're sleeping, which can cause scary night terrors and make you wake up a lot.

  • Attention-deficit/hyperactivity disorder and sleep: ADHD causes thoughts to race in your mind, which makes it challenging to go to sleep or stay asleep. This will also cause restlessness and hyperactivity. People with ADHD might wake up a lot during the night, which can result in not getting enough sleep and feeling tired throughout the day.

How to improve your sleep for better mental health


Getting sufficient sleep is essential for the well-being of your brain. If you struggle with sleep, it can worsen existing mental health issues or even lead to new ones. However, there is no need to worry as there are methods to enhance your sleep quality and promote better mental health.


Consider applying some of the tips below:


Establish a consistent sleep schedule: You should go to bed and wake up at the same time every day, even on weekends. This schedule can improve the quality of your sleep. Consistent sleep will also help regulate your body's internal clock and make sure you get better rest.


Create a relaxing bedtime routine: Create a peaceful bedtime routine to help your body unwind. You could read a book, take a nice bath, or do some calming exercises like deep breathing or meditation. Avoid doing anything too exciting or looking at screens like phones or laptops before bed, as they might make it hard for you to fall asleep.


Create a comfortable sleep environment: It's important to have the right sleeping setup if you want to sleep well. Make sure your room is cool, dark, and quiet so you can get the best rest. Having a comfy mattress and pillows that support your body is key. You can also use earplugs or a white noise machine to block out any annoying noise.


Limit stimulants and alcohol: Be careful with how much caffeine, nicotine, and alcohol you consume before going to bed. They can disrupt your sleep and make it hard to have a restful night.


Get regular exercise: Exercising often can help you sleep better. Try to do around 30 minutes of not-too-hard exercise most days. But don't do super intense workouts right before bed, because they can keep you awake!


Manage stress and anxiety: Dealing with stress and anxiety can ruin your sleep completely. There are actually exercises you can do to calm your mind before bed. 


These exercises include:


If you're struggling to fall asleep because of racing thoughts, keep a journal by your bed to write down your worries before you hit the hay.


Seek professional support: If you're still struggling with sleep problems or feeling down, don't be afraid to ask for help from a doctor or therapist. They can give you special advice and treatments to make your sleep better and help you feel happier overall.
