Sleep aids are designed to induce drowsiness and help you fall asleep or stay asleep through the night. They can be divided into three types: prescription medications, over-the-counter drugs, and dietary supplements. Over-the-counter sleep aids often contain antihistamines, which can block histamines that cause alertness. Natural sleep aids, such as melatonin and valerian, can also promote sleep but may have side effects like headaches and dizziness. Prescription sleep medications, such as benzodiazepines, stimulate chemicals in the brain that lead to sedation and reduced anxiety. While sleep aids can be helpful for occasional sleeplessness, they are typically not recommended for long-term use, and natural remedies like diet and lifestyle changes should be considered first.

What You'll Learn
Natural sleep aids
Melatonin Supplements
Melatonin is a hormone that is naturally produced by the body in response to reduced light exposure, signalling to your brain that it's time to sleep. Taking melatonin supplements is a popular way to promote sleep, especially for those experiencing jet lag or shift work disorder. Melatonin supplements are available over the counter and can help improve sleep quality, reduce sleep latency, and reset your sleep schedule. However, it's important to note that melatonin supplements are not regulated by the FDA, so dosages and ingredients may vary between manufacturers.
Valerian
Valerian is a perennial plant that has been used as a natural sleep aid for hundreds of years. It has a calming effect on the nervous system and can help promote a better night's sleep. Valerian is generally considered safe for short-term use, but it may cause side effects such as headaches and stomachaches in some people. It can be taken as a supplement or brewed as a tea using the dried root.
Magnesium
Magnesium is a natural mineral that has been linked to improved sleep quality. It is believed to promote relaxation and help regulate sleep cycles. Magnesium supplements or magnesium-rich foods may help those who struggle with sleep.
Cannabidiol (CBD)
CBD is a compound found in marijuana and hemp plants that has gained popularity as a natural sleep aid. It doesn't produce a high but has been shown to reduce anxiety and improve sleep quality. While research is ongoing, initial studies suggest that CBD may be effective in treating insomnia and improving sleep. However, it's important to note that CBD is still classified as a controlled substance in some states, and its legality may vary.
Herbal Teas
Herbal teas such as chamomile, passionflower, and lavender tea are often recommended as natural sleep aids. These teas have calming and soothing properties that can help relax the body and mind, making it easier to fall asleep.
In addition to these natural sleep aids, maintaining good sleep habits and hygiene is crucial for optimal sleep quality. This includes limiting exposure to unnatural light before bedtime, avoiding working out too close to bedtime, and creating a comfortable sleep environment.

Over-the-counter sleep aids
Over-the-counter (OTC) sleep aids are easily accessible and can be purchased without a prescription. They are available at drugstores and other retail locations and are typically antihistamines with a sedative effect. Antihistamines work by blocking histamines, which are substances in your body that cause alertness. Common ingredients in antihistamines include diphenhydramine and doxylamine succinate, which can also be found in many over-the-counter sleep aids. They help induce drowsiness by decreasing histamine levels in your brain, which is how the brain naturally prepares for sleep. However, antihistamines can cause side effects such as daytime grogginess, dry mouth, blurred vision, constipation, and trouble urinating.
OTC sleep aids also include natural supplements such as melatonin, valerian, and CBD. Melatonin is a hormone that promotes sleep by influencing when you fall asleep and wake up. It is available as a synthetic version over the counter and is commonly prescribed for jet lag, shift work disorder, and other issues related to circadian rhythm misalignment. Valerian has a natural calming effect on the nervous system and helps promote better sleep. CBD, a derivative of the cannabis plant, is also found in many OTC sleep aids. It does not contain THC, the psychoactive component of marijuana, and is being studied as a treatment for insomnia due to its anxiety-relieving properties. However, it is important to note that supplements like these are not regulated by the Food and Drug Administration (FDA) as strictly as other medications, so there may be some uncertainty about the accuracy of the listed ingredients.
While OTC sleep aids can be helpful for occasional sleeplessness or short-term sleep problems, they are generally not recommended for long-term use or chronic insomnia. They can cause side effects and may interact with other medications or health conditions. It is always advisable to check with your healthcare provider before taking any sleep aid to understand the potential benefits and risks.

Prescription sleep aids
Some prescription sleep aids cause drowsiness, while others silence the area of the brain that keeps you awake. They can also have side effects, including constipation, muscle weakness, digestive problems, and worsened snoring and sleep apnea. Approximately 8 out of 10 people experience a hangover effect the day after taking prescription sleep medication.
Some examples of prescription sleep aids include Doxepin (brand name Silenor), which may be prescribed for up to 3 months, and estazolam (Prosom), which is typically prescribed for short-term treatment of insomnia. Rozerem is another prescription sleep aid that has a low likelihood of misuse or dependency, although it can still cause side effects such as allergic reactions.

Side effects of sleep aids
Sleep aids can have both short-term and long-term side effects. Short-term use of sleep aids is generally considered acceptable, but long-term use should be avoided due to the potential for adverse health effects.
Common side effects of sleep aids include drowsiness, dizziness, and impaired focus the next day. Approximately 8 out of 10 people experience a hangover effect the day after taking sleep medicine, with symptoms such as muddled thinking and dizziness. These daytime effects can negatively impact daily tasks such as driving and working. Other short-term side effects include digestive problems, constipation or diarrhoea, muscle weakness, and dry mouth.
Long-term use of sleep aids can lead to dependency, drug tolerance, and more severe side effects. Sleep aids can interfere with normal breathing and are dangerous for people with certain chronic lung problems, such as asthma. They can also cause parasomnia, a disruptive sleep disorder characterised by unusual behaviours like sleepwalking, driving, or eating while still mostly asleep. Older adults are at a higher risk of health problems from sleep aids, including confusion, memory issues, and balance problems, which can increase the risk of falls and accidents. Additionally, long-term use of sleep aids can affect brain function and lead to issues such as poor memory, brain degeneration, and an increased risk of Alzheimer's disease and depression.
It is important to consult a doctor before taking sleep aids, especially for extended periods, as they can help manage side effects and gradually taper off the medication if needed.

Long-term use of sleep aids
Sleep aids are not recommended for long-term use. While they can help induce drowsiness and improve sleep quality in the short term, most sleep aids are not meant to be used continuously over an extended period.
The adverse effects of long-term sleep aid use can be detrimental to health. Sleeping pills, for instance, can lead to dependency, drug tolerance, and addiction. They can also cause side effects like dizziness, fatigue, and irritability, and long-term issues such as depression, especially in patients with liver and kidney disease. Additionally, older adults are more susceptible to the adverse effects of sleeping pills, which can cause confusion, memory issues, and balance problems, increasing the risk of falls and fractures.
Natural sleep aids, such as melatonin and valerian, are also not recommended for long-term use. While they are generally considered safer than prescription sleep aids, there is limited research on their long-term effectiveness and potential side effects. Melatonin, for example, is a synthetic hormone that mimics the body's natural sleep-wake cycle. However, it is typically prescribed for jet lag, shift work disorder, and other short-term sleep issues rather than long-term insomnia.
Furthermore, over-the-counter (OTC) sleep aids, which often contain antihistamines, should be used with caution. Antihistamines can cause drowsiness, but they can also interfere with other medications and make health conditions worse. There is a lack of research supporting the effectiveness of OTC sleep aids in treating insomnia, and sleep experts generally advise against their long-term use due to potential health risks.
In summary, while sleep aids can be beneficial for short-term relief from sleep issues, they are not intended for long-term use. The risks associated with prolonged use, including dependency, addiction, and adverse health effects, often outweigh the benefits. It is crucial to consult a healthcare provider before taking any sleep aid, especially for extended periods, to ensure safe and effective use.
