Sleep is often overlooked when it comes to maintaining mental health, but it plays a crucial role in how we feel, think, and function every day. While we may focus on managing stress, processing emotions, or finding better solutions to our problems, both the quality and quantity of sleep we get has a direct impact on our mental well-being. Lack of sleep can amplify stress, anxiety, and depression, while a good night’s rest can help us feel more balanced, focused, and emotionally resilient. In this blog, we’ll explore why sleep is so important for mental health and share practical tips to improve your sleep hygiene, so you can feel your best both mentally and physically.
The Link Between Sleep and Mental Health
While it may not seem like we are doing anything while we sleep, our brain and body are actually very busy and active when we are asleep. Sleep is necessary to maintain adequate physical and mental health.
- Restoration and Repair: During slow wave sleep, our bodies are busy undergoing processes of restoration and repair. Sleep allows our muscles, tissues, and bones to repair and grow stronger while also helping us heal from illness, boost immune functioning, and recover from different kinds of physical exertion. Sleep allows us to replenish our energy so we can feel refreshed and ready to complete the tasks of the following day.
- Emotion Regulation: Sleep also helps with emotion regulation through processing and making sense of our experiences. Specifically, during the rapid eye movement (REM) phase of sleep the brain revisits and processes emotional experiences from our day which then helps us integrate these experiences in a way that lessens the emotional charge of the memory. For example, with a good night’s sleep, you would be able to talk about the stressful parts of your week without reliving those experiences or feeling the emotions you felt while those experiences were occurring. Without quality sleep, your brain is unable to process the stressful events from your day which can make you less resilient in the face of stressful situations.
- Memory Consolidation and Learning: Getting enough sleep also promotes learning and memory. During REM sleep, the brain consolidates the information learned throughout the day and transfers that information into long-term memory. This helps us to retain new information so we can later recall it when needed. Sleep also helps strengthen neural connections that were formed during new learning which helps us more easily recall information and improve performance on new tasks and skills.
- Problem Solving and Decision-Making: Sleep also sharpens our cognitive abilities, such as creativity, critical thinking, and decision-making. Lack of adequate sleep can negatively impact our judgment, decision-making, and ability to solve complex problems.
- Hormone Balance: During sleep, the brain also works to regulate hormone levels, including cortisol, which is the hormone that gets released when we encounter stress. Without enough quality sleep, we are at risk for experiencing a build up of cortisol which can exacerbate symptoms of anxiety and depression.
As we can see, sleep plays a vital role in maintaining our physical and mental health. Over time, lack of sleep can lead to negative changes in mood, including feeling more anxious, irritable, angry, or having a shorter fuse. We may notice ourselves feeling more sensitive and triggered by minor annoyances. When we don’t get enough sleep, we do not have enough energy and emotional/mental resources to deal with the demands of our days.
A few nights of poor sleep can negatively impact us in the short-term but luckily our bodies are resilient and we can recover by getting adequate rest. Chronic sleep deprivation can entrench us in cycles that are more difficult to break. Lack of adequate quality or quantity of sleep may occur for a number of reasons including stress, anxiety and rumination, trauma, grief, increased activity levels, or physical health problems that impact our sleep. And, consistent lack of sleep can exacerbate these mental health issues, resulting in a cycle that can be difficult to break. Feeling groggy, irritable, fatigued, or exhausted, means we have less energy to give to not only our responsibilities, but also our relationships. Lack of sleep can put strain on our relationships when we are unable to show up as our best selves. Relationship strain is a further stressor that can worsen symptoms of anxiety, depression, stress, burnout, or trauma. Thus, chronic sleep deprivation can lead to significant problems in our day to day lives.
Practical Sleep Hygiene Tips for Improving Mental Health
There are a variety of practical steps to help improve your quality and quantity of sleep, that will leave you feeling well-rested and ready to tackle the day. As with developing any new habit, choose one or two small changes to incorporate into your sleep routine. The following are tips for improving your sleep hygiene:
- Create a Sleep Conducive Environment: Make your sleep space calming and comfortable. This can include ensuring your room is dark, cool, and quiet. Choose bedding and decorations that create a calming atmosphere for you. Your bedroom should feel like a safe space that is solely meant for sleeping. Sleeping in a clean space with minimal clutter can also be supportive for sleep. Other items to add to your space may include candles, soft blankets, soft lighting, plants, a fan, and a white noise machine. Social media can be a great place to feel inspired and get creative!
- Establish a Sleep Routine: Instead of jumping from school, work, or other tasks straight into sleep, allowing yourself time to wind down helps prepare your mind and body for sleep. A sleep routine can involve a number of different activities, both relaxing and practical. Relaxing activities may include: reading a book, listening to relaxing music or a meditation, journaling, gentle stretches, putting on cozy pajamas, and drinking a warm cup of tea. Practical activities include taking a shower, brushing teeth, engaging in a skincare routine, and preparing your space for sleep. Getting our bodies into a routine gives our body and brains signals that it is time to wind down for bed and our bodies begin to expect and anticipate sleep. This makes it easier to fall asleep.
- Designate a Time to Put Away Screens: Using screens before bed negatively impacts our ability to fall asleep. Blue light from screens can suppress melatonin production, which is the hormone that regulates and signals sleep. Screen time can also induce mental arousal which makes it harder to relax and fall asleep. Consider putting away screens, including television, an hour before bed and transitioning to activities that do not involve screentime.
- Implement a Consistent Sleep Schedule: If you are struggling with sleep, developing a consistent sleep schedule can help improve both the quality and quantity of sleep you are getting. This means going to bed and waking up at the same time every day, even on the weekends.
- Avoid Stimulants: Stimulants, like caffeine or nicotine, increase energy levels and alertness, which is the opposite goal of sleep. Stimulants can also lead to reduced deep sleep and REM sleep, which are essential sleep stages which are essential stages of our sleep cycle.
- Practice Relaxation Techniques: There are a variety of techniques that can help our bodies unwind and relax before going to bed. Some popular options include deep breathing exercises, progressive muscle relaxation, and mindfulness meditations. These techniques are designed to help us become aware of our breath and slow it down, which signals relaxation and safety to our bodies and minds. Progressive muscle relaxation involves tensing and releasing different muscle groups which helps alleviate muscle tension. Mindfulness meditations can help slow down our thought processes which can be helpful if we have a tendency to overthink or ruminate before sleep. There are many meditation apps that include meditations specifically for sleep, including Insight Timer, Calm, Headspace, and Simple Habit. YouTube is also a great place to find free meditations designed to help with sleep.
- Physical Activity: Exercise during the day can help regulate the hormone melatonin which is involved in our sleep-wake cycle. Physical activity also tired the body which can promote deeper and more restful sleep.
