Sleep is a cornerstone of our health and happiness, and for those who find it elusive due to a common sleep disorder called insomnia, it doesn’t have to diminish their quality of life. This condition is characterised by difficulty falling, staying, or waking up too early; insomnia can lead to fatigue, mood changes, and performance issues at work or school.
Fortunately, help is closer than you might think: exercise! Let’s explore the exciting connection between physical activity and sleep to uncover how staying active can lead to more restful nights and brighter days!
Understanding Insomnia
Insomnia can be classified into several types:
- Acute Insomnia: Short-term episodes often caused by stress or significant life changes.
- Chronic Insomnia: Long-term condition lasting three months or more, often linked to underlying health issues.
- Onset Insomnia: Difficulty falling asleep at the beginning of the night.
- Maintenance Insomnia: Trouble staying asleep throughout the night.
Common Causes Of Insomnia
Insomnia can be triggered by stress, anxiety, poor sleep habits, medical conditions (and some medications) and psychological factors. Understanding these triggers is the first step toward finding effective treatments.
- Medical conditions such as chronic pain, asthma, arthritis, gastrointestinal issues, neurological disorders, and cardiovascular diseases, along with hormonal changes due to the menstrual cycle, pregnancy, or menopause, can all contribute to insomnia.
Additionally, medications prescribed for these conditions may contain stimulants that interfere with sleep and keep individuals awake.
- Psychological factors like stress and anxiety are among the most prevalent causes of insomnia. Stressful life events or excessive worrying can disrupt the balance of neurotransmitters in the brain, making it difficult to relax and fall asleep.
The Science Behind Exercise and Sleep
Exercise affects the body in various physiological and psychological ways, significantly improving sleep quality. Here’s a concise breakdown:
Reduction of Stress and Anxiety
Regular physical activity is a powerful tool for improving sleep by addressing two major contributors to insomnia: stress and anxiety. Exercise lowers cortisol levels, the stress hormone, and releases endorphins, the “feel-good” hormones. These endorphins interact with brain receptors to reduce pain perception and trigger a sense of well-being. By incorporating regular exercise into your routine, you can effectively mitigate the stress and anxiety that often disrupt sleep.
Regulation of Circadian Rhythms
The body’s internal clock, or circadian rhythm, which regulates sleep-wake cycles, can be influenced by physical activity. Engaging in exercise, especially in natural daylight, helps synchronise these rhythms, promoting a more consistent sleep pattern. Morning exposure to natural light during exercise can regulate and suppress melatonin production, the hormone that signals to the body when it is time to sleep.
Promotion of Deep Sleep
The amount of time spent in deep N3 or ‘slow-wave’ sleep, the most restorative sleep stage, is increased through exercise. This phase is crucial for physical health, as it is when the body repairs muscles, tissues, and cells. During deep sleep, growth hormones essential for development are released, supporting immune function, cellular regeneration, and energy restoration.
Body Temperature Regulation
Exercise raises your body temperature, and as it cools down afterwards, you start to feel sleepy and ready for rest. This cooling process is important for helping you fall asleep and stay asleep.
Improved Metabolic Function
Boosting your metabolism, the process by which your body converts food into energy is a benefit of regular exercise. A well-functioning metabolism helps maintain steady energy levels and reduces the risk of sleep-disrupting conditions like obesity and sleep apnoea. These benefits can ultimately lead to better sleep quality.
Types of Exercise That Improve Sleep
Exercise plays a pivotal role in enhancing sleep quality by addressing various factors that contribute to restful sleep. Different forms of exercise offer unique benefits that can help improve sleep patterns and overall health. Incorporating a variety of exercises into your routine can lead to improvements in how well you sleep. Here’s a closer look at the types of exercise that are particularly effective for promoting better sleep:
Aerobic Exercise
Walking, running, cycling, and swimming increase heart rate and breathing, promoting better sleep quality. Aerobic exercise is particularly effective in reducing sleep latency and increasing total sleep time. Engaging in at least 150 minutes of moderate aerobic or 75 minutes of vigorous activity each week can significantly enhance sleep quality.
Resistance Training
Strength training exercises, such as weightlifting, improve muscle tone and overall physical fitness, which can contribute to better sleep. Incorporating resistance training into a fitness routine can enhance sleep efficiency and depth. Research has shown that resistance training can increase slow-wave sleep, the deepest phase of non-REM sleep.
Yoga and Stretching
Mind-body exercises like yoga and stretching are well-known for their relaxation benefits. These activities help reduce stress and anxiety, creating an environment conducive to sleep. Yoga, in particular, incorporates breathing exercises and meditation, which calm the mind and prepare the body for restful sleep. The Research Repository at RMIT has found that practising yoga regularly can improve both sleep quality and duration.
Practical Tips for Using Exercise to Combat Insomnia
To harness the sleep-promoting benefits of exercise, consider the following tips:
Consistency is Key
Engaging in at least 30 minutes of moderate-intensity exercise most days of the week is essential for improving sleep. This consistency helps regulate the body’s internal clock, leading to long-term improvements in sleep patterns. Regular physical activity promotes better sleep quality and overall health.
Timing Matters
While exercise is beneficial, the timing of workouts can impact sleep. Avoid vigorous exercise too close to bedtime, as it may interfere with the ability to fall asleep. Morning or early afternoon workouts are ideal. Exercising in the morning can also enhance exposure to natural light, further aiding the regulation of circadian rhythms.
Start Slowly
If you’re an exercise novice, start with low-impact activities and gradually increase intensity. This approach helps prevent injury and promotes long-term adherence. For example, begin with walking or gentle yoga before progressing to more strenuous activities.
Create a Routine
Establishing a consistent exercise routine can help regulate sleep patterns. Incorporate a mix of aerobic, resistance, and mind-body exercises for comprehensive benefits. A varied routine can also keep workouts interesting and engaging.
Overcome Barriers
Identify and address potential barriers to exercise, such as lack of time or motivation. Finding enjoyable activities and setting realistic goals can enhance adherence. Group exercise classes or workout partners can also provide motivation and accountability.
Monitor Progress
Track exercise habits and sleep patterns to identify what works best for improving sleep. Using a journal or mobile app can help you monitor progress and make necessary adjustments. Exercise is a highly effective, natural remedy for insomnia, providing a comprehensive approach to enhancing sleep quality. Regular physical activity can significantly improve sleep by reducing stress and anxiety, regulating your internal clock, and promoting deep, restorative sleep.
However, while exercise is a powerful tool, it is not a cure-all. If sleep issues persist, it is crucial to consult a healthcare professional for a thorough evaluation and a personalised treatment plan.
