Before taking any sleep aid, it's always recommended to consult your healthcare provider to ensure your safety and find the best solution for your specific needs.

What You'll Learn
Melatonin
The popularity of melatonin as a sleep aid is increasing, with about 3 million Americans using it in 2012, according to a survey by the Centers for Disease Control and Prevention. Melatonin supplements are synthetic versions of the hormone that help regulate the sleep-wake cycle. They are typically taken in doses of 1 to 5 milligrams, 30 minutes to 2 hours before bedtime. Melatonin is fast-acting, with effects usually felt within 20 to 40 minutes, and it stays in the system for about five hours.
It is important to note that melatonin supplements are not regulated as strictly as prescription or over-the-counter drugs and are not approved for specific uses. While they may help with insomnia and jet lag, there is limited scientific evidence of their effectiveness in improving sleep patterns. Additionally, melatonin should not be taken by those who are pregnant or breastfeeding, or have certain medical conditions, such as autoimmune disorders, seizure disorders, or depression. It is recommended to consult a healthcare provider before taking melatonin, especially for individuals with diabetes or high blood pressure, as it can affect blood sugar and blood pressure levels.
To maximize the benefits of melatonin, it is advisable to limit exposure to blue and green light from electronic devices, as this can interfere with its effects. Getting exposure to daylight during the morning and afternoon can also help regulate melatonin production. While melatonin can be beneficial for short-term sleep issues, it is not a long-term solution for chronic insomnia. If sleep troubles persist, it is important to consult a healthcare professional to address any underlying causes and explore alternative treatments.

Valerian
Research suggests that valerian root can improve sleep quality and reduce the time it takes to fall asleep. It may also help reduce anxiety and improve symptoms related to OCD, menopause, and PMS. However, the effectiveness of valerian root varies among individuals, and some studies have found that it has no significant impact on sleep. The recommended dosage of valerian root is between 400 and 1,410 mg per day, but it is important to consult a healthcare professional to determine the safest and most effective dose for your specific needs.

Antihistamines
Diphenhydramine and doxylamine succinate are common sedating antihistamines found in over-the-counter sleep aids. They work by blocking the body's histamine reaction, which includes alertness. This blocking effect leads to drowsiness as a side effect. Products containing these antihistamines include Benadryl, Unisom, and ZzzQuil.
While antihistamines can be effective in helping people fall asleep, they should be used with caution. It is recommended to start with the lowest possible dose to determine the appropriate amount needed to aid sleep. Additionally, antihistamines are not recommended for long-term use as the body can develop a tolerance over time, requiring higher doses to achieve the same effect.
It is important to consult a healthcare professional before taking any sleep medication, including over-the-counter antihistamines. They can advise on potential side effects, drug interactions, and risks associated with these medications. Additionally, they can recommend alternative treatments such as cognitive behavioral therapy or natural remedies like valerian root or lavender essential oil.

Cognitive behavioural therapy
Over-the-counter sleep aids are typically recommended for short-term use, such as overcoming jet lag or a brief bout of sleeplessness. These sleep aids are not intended for long-term chronic insomnia. It is always advisable to consult a doctor to understand the side effects, risks, and possible drug interactions. Some common over-the-counter sleep aids include antihistamine-containing medications like Benadryl Allergy®, Advil PM® or Tylenol PM®, which can induce drowsiness. However, these may cause side effects like daytime grogginess, blurred vision, constipation, and confusion. Natural sleep aids such as melatonin and valerian supplements are also available, with melatonin being a hormone that the body naturally produces to regulate sleep.
Now, let's shift our focus to Cognitive Behavioral Therapy (CBT-I) as a sleep aid. CBT-I is a structured and evidence-based approach to addressing insomnia, and it has been proven effective for both short-term and chronic insomnia. CBT-I typically involves working with a trained provider over several sessions to identify thoughts, feelings, and behaviours that contribute to insomnia. The therapy helps individuals explore the connection between their thoughts, actions, and sleep quality.
During CBT-I, thoughts and feelings about sleep are examined to determine if they are accurate, and behaviours are assessed to see if they promote restful sleep. Cognitive interventions aim to restructure unhelpful thoughts about sleep, while behavioural interventions focus on stimulus control, sleep restriction, and relaxation techniques to establish healthy pre-sleep habits. The goal is to break the cycle of insomnia by challenging and altering unproductive thoughts and beliefs.
CBT-I is typically a short-term treatment, with most individuals requiring 6 to 8 sessions, although the length may vary depending on individual needs. It is a recommended first step before resorting to sleeping pills, as it has been shown to be an effective tool for improving sleep and curing insomnia. CBT-I helps individuals develop skills to calm their minds and manage stressors that interfere with sleep, ultimately improving sleep quality.

Prescription sleep aids
Sleep medications are available over the counter (OTC) or by prescription. While OTC sleep aids are easily accessible, prescription sleep aids are stronger and often more effective. However, they come with a higher risk of side effects, misuse, and dependency.
Some prescription sleep aids come with a higher risk of misuse and dependency, such as suvorexant (Belsomra). Additionally, some may cause allergic reactions or other side effects like edema, where the body's tissues contain too much fluid. People should also limit their alcohol consumption when taking certain prescription sleep aids, as it can increase the effects of alcohol.
It is important to consult a doctor before starting any prescription sleep medication to ensure safe and effective use.
