Sleep aids are designed to help people with sleep disorders like insomnia, or those who have difficulty falling asleep. They are available over the counter (OTC) or by prescription. OTC sleep aids often contain antihistamines, which cause drowsiness by blocking histamines—the substances in the body that cause alertness. Natural sleep aids include melatonin, valerian, and kava, which can be purchased as dietary supplements. Prescription sleep aids include benzodiazepines, Z-drugs, barbiturates, and antidepressants. These medications work by stimulating chemicals in the brain that cause sedation and relaxation, ultimately promoting sleep. While sleep aids can be effective in the short term, they are not meant for long-term use and can cause side effects such as constipation, muscle weakness, and daytime drowsiness.

What You'll Learn
Natural sleep aids
Magnesium is another natural sleep aid that has been the subject of several studies. One such study, published in the Journal of Research in Medical Sciences, investigated "The Effect of Magnesium Supplementation on Primary Insomnia in the Elderly". Other natural sleep aids include valerian root, which has been used for hundreds of years and is thought to boost relaxation by raising levels of GABA (gamma-aminobutyric acid), a brain chemical that promotes relaxation and sleep. However, there is mixed evidence for the effectiveness of valerian, and it may cause headaches and stomachaches.
Some studies have also found that CBD can act as a natural sleep aid, relieving anxiety and helping people with insomnia to fall asleep. However, more research is needed before it can be routinely recommended for sleep disorders, and it is not recommended for people who are pregnant or nursing.
Other natural sleep aids include herbal teas such as chamomile, which has been used for centuries and is believed to have a calming effect. It is also thought to have flavonoids that may interact with benzodiazepine receptors in the brain involved in the sleep-wake transition. However, there is not yet enough proof to say that it is effective in treating insomnia. Kava is another herbal remedy used for stress and anxiety relief and insomnia, and some say it may induce relaxation without hindering memory or motor function, although research findings have been conflicting.
It is important to remember that even natural sleep aids should not replace good sleeping habits. Getting a good amount of sleep is essential for health, as it helps the body and brain to function properly. Before taking any natural sleep aid, it is recommended that you consult a medical professional, as they may have side effects or interact with other medications or conditions.

Prescription sleep aids
There are several types of prescription sleep aids, including antidepressants, barbiturates, benzodiazepines, and Z-drugs. Benzodiazepines, such as alprazolam (Xanax) and diazepam (Valium), work by stimulating a chemical in the brain called GABA, leading to sedation, muscle relaxation, and reduced anxiety. However, they can be addictive and are typically prescribed for short-term use only. Z-drugs like zolpidem (Ambien) and eszopiclone (Lunesta) also work by slowing down brain activity. They are often preferred over benzodiazepines due to a lower risk of dependence.
Some prescription sleep aids may cause parasomnia, a disruptive sleep disorder where individuals may sleepwalk, eat, talk, or even drive while mostly asleep. This can be dangerous, and individuals usually do not remember these behaviours. Additionally, sedatives can worsen snoring and sleep apnea, a potentially life-threatening condition.

Over-the-counter sleep aids
Over-the-counter (OTC) sleep aids are easily accessible without a prescription and can be purchased at a drugstore or other retail locations. They are intended to help with occasional sleeplessness and can come in the form of medication or natural supplements. OTC sleep aids often contain antihistamines, which are used to treat allergies but can also cause drowsiness. Diphenhydramine and doxylamine are common antihistamines found in OTC sleep aids, and they can be found in products such as Benadryl Allergy®, Advil PM®, or Tylenol PM®. It is important to be aware of possible side effects and risks associated with OTC sleep aids, as they can interfere with other medications or cause side effects such as dry mouth, blurred vision, and fatigue.
Natural supplements such as melatonin, valerian root, and cannabidiol (CBD) are also available as OTC sleep aids. Melatonin is a chemical naturally produced by the body to regulate sleep and wake cycles, and OTC melatonin is a synthetic version that may be helpful for people with jet lag or delayed sleep-wake disorders. Valerian root is said to help people fall asleep and reduce anxiety and stress. While these natural supplements are widely taken, there is limited data on their effectiveness, and they may have minor side effects such as headaches, dizziness, or nausea.
It is recommended to consult a healthcare provider before taking any OTC sleep aids to ensure they are safe and will not interact with other medications. Most sleep problems can be corrected without medication, and healthcare providers typically recommend trying other methods to improve sleep before resorting to sleeping pills. These can include good sleep habits, lifestyle adjustments, and cognitive behaviour therapy to address stressors that may be causing sleep issues.

Side effects
Sleep aids, including natural ones like melatonin, can cause side effects. Melatonin is a hormone that promotes sleep due to its ability to influence when you fall asleep and wake up. While a melatonin overdose is highly unlikely, taking too much melatonin may cause some side effects, such as sleep-induced injuries, vehicle accidents due to impaired judgment and coordination, and in some cases, even self-harm and crimes.
Sleeping pills can also cause a range of side effects, from constipation to muscle weakness. Approximately 8 out of 10 people experience a hangover effect the day after taking sleep medicine. They feel drowsy, have muddled thinking, and experience dizziness or balance problems. These daytime effects can negatively impact your ability to drive, work, and complete daily tasks. Some people may also develop parasomnias, or unusual behaviours like walking, driving, or eating in their sleep.
Sleeping pills are not recommended for long-term use, as they can lead to dependency and withdrawal symptoms when discontinued. They can also interfere with other medications or cause serious side effects, especially in older adults, who are at a greater risk of health problems and may experience prolonged drowsiness, confusion, and memory issues, which can increase the risk of falls and accidents.
Additionally, it is important to note that sleeping pills should not be mixed with alcohol or other sedatives due to the risk of dangerous interactions and even death. Certain foods, such as grapefruit and grapefruit juice, must also be avoided when taking sleeping pills as they can cause harmful reactions.

Addiction and withdrawal
Sleep aids and sleeping pills can be highly addictive, and users can become dependent on them in a very short time, sometimes just a few weeks. Withdrawal symptoms can be intense and even life-threatening, and medical detox is always recommended. The withdrawal process and duration vary from person to person, but symptoms can begin within a few hours to a few days of quitting and can last for several weeks.
Withdrawal symptoms can include insomnia, restlessness, anxiety, shivering, circulation problems, dizziness, and fainting. In some cases, seizures can occur, which is why medical supervision is essential. During medical detox, doctors monitor the patient's vital signs and manage symptoms with medication. They will also address any health concerns that arise, such as administering IV fluids to balance electrolytes and rehydrate the patient.
To avoid a relapse, it is important to keep withdrawal symptoms to a minimum. The best way to do this is to gradually reduce the dose of the sleep aid over time with the guidance of a doctor. This process is known as tapering and is the preferred method of treatment as it results in less severe withdrawal symptoms. Abruptly quitting sleep aids can make the withdrawal process more challenging and intense.
In addition to medical detox, psychotherapy, such as cognitive-behavioural therapy (CBT), can be beneficial. CBT can help individuals learn healthy sleeping habits and develop skills to manage stress and improve cognitive functions. It teaches behavioural modifications to help patients fall asleep without the use of prescription sleep aids.

Frequently asked questions
Sleep aids can be divided into three main types: prescription medications, over-the-counter drugs, and dietary supplements. Prescription medications are stronger than over-the-counter drugs and usually include benzodiazepines, barbiturates, and antidepressants. Over-the-counter sleep aids often contain antihistamines, which can also cause drowsiness. Natural dietary supplements such as melatonin, valerian, or kava are also available without a prescription.
Sleep aids work by inducing drowsiness and promoting relaxation. They target the brain's GABA receptors, which control alertness and relaxation. This causes sleepiness, muscle relaxation, and reduced anxiety. Some sleep aids, like Z-drugs, slow down brain activity to induce a sedative effect. Others, like orexin receptor antagonists, block the production of orexin, a chemical that makes you feel alert.
Sleep aids can have various side effects, including constipation, muscle weakness, decreased sexual drive, and potential weight gain. They can also cause confusion, daytime drowsiness, and impaired thinking. Additionally, sleep aids may lead to dependency, drug tolerance, and withdrawal symptoms if abruptly discontinued. It is important to consult a healthcare professional before taking any sleep aid to discuss potential side effects and determine the most suitable treatment.
