The Role of Sleep in Mental and Emotional Health

Sleep is not just a time to rest but it has become one of the most effective ways to improve your mental & emotional wellness.

Due to a variety of factors including work, stress, and excessive screen time, many people are experiencing diminished amounts of sleep daily and do not realize how much sleep affects their mental and emotional state.

Adequate amounts of sleep help the brain to reset, process emotions, stay balanced, and promote wellness.

Insufficient amounts of sleep cause more stress, anxiety, mood swings and potentially lead to long-term psychological illnesses.

Let's take an in-depth look at the necessity of sleep in relation to mental and and emotional wellbeing, and ways that we can enhance our sleep patterns.

Need for Sleep in Relation to Mental Functioning

While we are sleeping, our brains are also working very hard. They are not “off” but they are repairing themselves, organizing themselves, and strengthening themselves.

While sleeping, our brains:

• processes emotions and activates memories;
• eliminate toxins from our brains that have accumulated from the day;
• restores the chemical balance necessary for focus and mood;
• reinforces/competes with a new learning through memory and decision making.

If you do not have sufficient amounts of sleep, you interrupt these functions in your brain and the onset of mental health disorder is very probable.

Emotional Well-Being and Sleep

1. Emotions are Regulated

Adequate sleep helps individuals regulate their emotional responses to anger, sadness, and frustration. When you have sufficient restorative sleep, you tend to have more patience, be calm, and your emotions remain stable.

Lack of sleep causes:

• Mood Fluctuations
• Emotional Reactivity
• Overreacting to Minor Issues
• Overwhelmed by Emotions

These emotional reactions are caused by a sleep-deprived brain that changes how the emotional regulating portion of the brain operates.

2. Decreased Stress Levels

Sleep and stress are often connected. Adequate sleep decreases levels of the hormone cortisol, which regulates how we deal with stress. However, when an individual does not get adequate sleep, the individual may experience increased levels of stress due to lack of sleep, which may result in an inability to relax for the following day.

Long-term chronic sleep deprivation can lead to:

• Chronic Tension
• Burnout
• Emotional Exhaustion

Good sleep will allow for recovery from daily stressors on both the body and mind.

3. Enhanced Clarity and Concentration

Good sleep enhances concentration, memory, and clear thought. 

After having a good night of sleep, individuals can:

• Concentrate on what they do at work and school
• Make better decisions regarding their health
• Solve problems more effectively

When an individual does not get enough sleep, their ability to think clearly is impaired, resulting in difficulty with concentration, a feeling of being "foggy" in thought, and increased levels of anxiety and frustration.

The Connection Between Sleep & Mental Health

Poor sleep can significantly affect many different mental health issues,

including the following:

• Anxiety

Sleep deprivation can lead to feelings of worry, anxious thoughts, and nervousness. On the other hand, anxiety can make it difficult to fall asleep, thus perpetuating a vicious cycle.

• Depression

Insomnia is one of the common symptoms associated with depression. The longer someone is sleep deprived, the greater the chance that they will experience low mood and low motivation or hope.

• Emotional Fatigue

Individuals who consistently sleep less than 6 to 7 hours per night are more prone to feel exhausted and disconnected from their emotions.

For this reason, improving the quality of a person's sleep is frequently one of the first steps taken in supporting their recovery from mental health issues.

The Quantity of Sleep You Require

Most adults need between 7 and 9 hours of sleep per day; however, the quality of your sleep is equally as important as the quantity of sleep.

Quality sleep includes:

• Falling asleep within 20 to 30 minutes after lying down
• Sleeping continuously through the night, with few awakenings
• Awakening feeling rested rather than drained

The Symptoms That Indicate Sleep is Affecting Your Mental Health

If you find that you have been having trouble sleeping, and are experiencing the following symptoms, you should take steps to improve the quality of your sleep:

• Feeling anxious or sad but unable to identify the source of your anxiety or sadness
• Having low energy and/or motivation
• Difficulty concentrating
• Becoming irritable
• Feeling emotionally numb or overwhelmed

These signs represent your body's attempts to signal you that it is time to take a break and rest.

Ways to Enhance Sleep for Better Emotional Health

1. Maintain an Established Sleep Schedule

Stick to the same bedtime and wake-up time regardless of the day of the week. By doing this every day helps you have consistent timing in your body's internal clock, leading to good sleep.

2. Limit Your Use of Screens Prior to Sleep

Mobile devices and televisions emit blue light that disrupts the production of melatonin (the hormone that helps you get a good night's sleep). 

It is advisable that you limit your use of electronic devices for approximately 1 hour, before bedtime.

3. Establish a Calm Evening Routine

Reading, gentle stretching or performing deep breathing exercises before going to bed will help to send a signal to your brain that the time has come to sleep.

4. Control Your Daytime Stress

Keeping a journal, exercising, practicing mindfulness or doing something else that is short in duration during the day can help to reduce the time you spend worrying at night.

5. Make Your Sleeping Area as Comfortable as Possible

Keeping your sleeping environment as dark as possible, quite, and at a cooler temperature will benefit the quality of your sleep. Simple changes can provide a significant improvement in sleep.

Important Note About Sleep

Sleep is essential for a healthy mind and body. When you are sleep deprived, it becomes increasingly difficult for you to control your moods, cope with stress, and stay positive.

By placing sleep at a higher priority, you are taking care of yourself and your overall emotional well-being.

Before making any changes in your sleep, start off small and stay committed. In the end, when you are well rested after a good nights' rest, you will have a healthier mind!
