Sleep is an essential function that allows the body and mind to recharge, and getting a good night's sleep is about more than just the number of hours spent in bed. Sleep quality and a consistent sleep schedule are also important. There are many natural sleep aids available, from lavender to melatonin supplements, but they are not all safe or effective. Natural sleep aids are not regulated in the same way as medications, so it's important to do your research and consult a doctor before trying anything new. While some natural sleep aids may help, addressing your sleep hygiene and making small changes to your sleep routine is usually the best approach.

What You'll Learn
Natural sleep aids
Melatonin Supplements
Melatonin is a natural hormone that helps regulate your body's sleep cycle. It is triggered by the body's response to reduced light exposure, which should naturally occur at night. However, exposure to artificial light from phones, laptops, or TVs can prevent melatonin release, making it hard to fall asleep. Melatonin supplements are available over the counter and can help improve sleep quality, especially in individuals with sleep disorders. It is generally safe for healthy adults, but it is unregulated, so dosages and ingredients may vary.
Magnesium
Magnesium is a mineral that is important for brain function and heart health. It can help quiet the mind and body, making it easier to fall asleep. Studies suggest that magnesium's relaxing effect may be due to its ability to regulate melatonin production.
Valerian Root
Valerian is a perennial plant that has been used as a sleep aid for centuries. It may help raise GABA levels, which boosts relaxation and improves sleep quality. While some studies suggest its positive effects are negligible, short-term intake appears safe for adults, with minor and infrequent side effects. However, the safety of long-term use is uncertain, especially for certain populations.
Cannabinoids (CBD and THC)
Cannabinoids, including cannabidiol (CBD) and delta-tetra-hydrocannabinol (THC), are compounds derived from the cannabis plant. Marijuana, created from the cannabis plant, is known to promote sleep. CBD, in particular, has been found to relieve anxiety and enhance sleep quality. However, research on the long-term safety of CBD is limited, and it is not recommended for pregnant or nursing women. The legality of CBD also varies depending on location.
Herbal Teas
Herbal teas, such as chamomile tea, are caffeine-free and can help promote sleep. Chamomile tea is recommended for patients with sleep troubles as it is believed to have relaxing properties without the side effects or interactions associated with other substances. Tart cherry juice is another option, as it may support melatonin production and enhance sleep quality.
In addition to these natural sleep aids, maintaining good sleep hygiene is crucial. This includes practices such as limiting exposure to artificial light before bed, exercising regularly (but not too close to bedtime), and creating a comfortable sleep environment.

Exercise
The timing of exercise is important to consider. Some people find that exercising close to bedtime keeps them up at night. This is because aerobic exercise causes the body to release endorphins, creating a level of brain activity that may prevent some people from falling asleep. These individuals should exercise at least 1-2 hours before bedtime, giving their brain time to wind down. However, the impact of exercise timing on sleep quality is still being debated, and some people can tolerate a hard workout in the evening and still sleep well.
The type of exercise also plays a role in improving sleep quality. Moderate-intensity aerobic exercise, strength training, and mind-body exercises like yoga and tai chi have been found to improve sleep outcomes and decrease insomnia. Light exercises of 10 minutes per day in the morning have been found to improve sleep quality, while high-intensity exercises for more than 90 minutes in the evening have been associated with difficulty sleeping.
The key to reaping the benefits of exercise for better sleep is consistency and regularity. Aim for at least 30 minutes of moderate-intensity physical activity per day, which can be broken down into smaller chunks if needed. Pick an exercise you enjoy to help you stick with it and make it a part of your daily routine.

Light exposure
Studies have shown that light exposure during the day helps us feel awake, and this has the same effect at night. Looking at screens or keeping the lights on before bed can make it harder to fall asleep. It is recommended to dim the lights and turn off screens at least one hour before bedtime.
Light therapy is a treatment for circadian rhythm disorders, which are often caused by shift work. Circadian rhythm disorders can cause insufficient sleep, excessive sleepiness, mood problems, and elevated risk of accidents. Light therapy uses a high-powered lamp or a light therapy box to retrain the body's internal clock. It is also known as bright light therapy, phototherapy, or circadian light therapy. Light therapy can be helpful for people with insomnia, circadian rhythm sleep disorders, and some types of depression. Light therapy is also beneficial for individuals with non-seasonal depression, although it is more effective when combined with an antidepressant. Light therapy can also be used to treat sleep-wake disturbances in geriatric care and to reduce general listlessness.
The timing of light exposure is important. Our circadian rhythm is most sensitive to light about one hour after we wake up and about two hours before bedtime. Exposure to light during these times will affect when the body naturally gets sleepy and is ready to fall asleep. Getting outside for at least an hour each morning or afternoon can help you feel more awake and alert.

Sleep quality
To enhance sleep quality, it is important to address sleep hygiene and make adjustments to sleeping habits. This includes paying attention to one's sleep environment, such as reducing exposure to light, especially blue light, which negatively affects melatonin levels. Using a flashlight for middle-of-the-night bathroom breaks is recommended over turning on bright lights, as it minimises visual disruption. Additionally, creating a comfortable sleep environment by layering bedding to adjust the temperature can improve sleep quality.
Natural sleep aids can also be considered. Melatonin supplements can be considered for short-term use. Melatonin is a natural hormone that helps regulate the body's sleep-wake cycle, and it is particularly beneficial for those with insomnia or delayed sleep phase syndrome. However, it is important to consult a doctor before starting any supplement, as they are not regulated as strictly as medications and may have side effects or interactions.
Other natural sleep aids include valerian root, which may offer minor improvements in sleep latency, and magnesium, which can help quiet the mind and body. Some people also find that drinking warm milk, chamomile tea, or tart cherry juice before bed improves their sleep, although scientific evidence for these remedies is limited.
Physical activity can also enhance sleep quality, particularly moderate aerobic exercise, which increases the amount of slow-wave (deep) sleep. However, it is crucial to avoid exercising within two hours of bedtime, as exercise stimulates the release of energising endorphins and raises the core body temperature, making it harder to fall asleep.

Sleep duration
Maintaining a consistent sleep schedule is crucial for overall sleep quality. Disruptions in sleep patterns, such as those experienced by shift workers or during stressful events, can pose challenges to getting quality sleep. Additionally, the notion of "catching up" on sleep during days off is a myth, as research suggests that the benefits of extra sleep after a sleepless night are limited.
Natural sleep aids are a popular option for those seeking to improve their sleep duration and quality. Options include lavender, chamomile tea, tart cherry juice, and melatonin supplements. However, it's important to consult a doctor before starting any new supplement, as natural remedies can have side effects and interactions with medications.
Exercise is another factor that influences sleep duration. Moderate aerobic exercise has been found to increase the amount of slow-wave (deep) sleep, but it should be timed correctly, as it can also release endorphins that keep people awake. It is recommended to avoid exercising within two hours of bedtime to maintain a healthy sleep duration.
