Sleep preventer is a simple app that prevents a computer from going into sleep mode, hibernating, or starting the screensaver. It works by simulating a keypress every 59 seconds so that the machine thinks you're still working and doesn't lock the screen or activate the screensaver. While Sleep Preventer is a free and proprietary app, there are several alternatives available for free, such as Caffeine for Windows, NeverNap, and Amphetamine. Now, if you were actually looking for information on sleep aids, these are available as both non-medicated and medicated options, with the latter including over-the-counter and prescription medication.

Natural sleep aids
Sleep is incredibly important for our health, and getting a good amount of sleep can help our bodies and brains function properly. Natural sleep aids can be a great way to improve your sleep without the side effects that often come with prescription sleep medications.
Melatonin
Melatonin is a hormone that is produced by the body and signals to your brain that it is time to sleep. Melatonin is triggered by the body's response to reduced light exposure, which should occur naturally at night. However, exposure to artificial light from phones, laptops, or TVs can prevent the release of melatonin, making it difficult to fall asleep. Melatonin supplements are available over the counter and can help improve sleep quality in individuals with sleep disorders. It is recommended to take 1-3 milligrams of melatonin 2 hours before bed.
Valerian
Valerian is a perennial plant that has been used as a sleep aid for hundreds of years. It is thought to help raise levels of GABA, which boosts relaxation. Valerian is considered safe for short-term use but may cause headaches and stomachaches in some people. It can be taken as a supplement of 300-600 milligrams or brewed as a tea with 2-3 grams of the dried root infused in water.
Cannabidiol (CBD)
CBD is a compound found in marijuana and hemp plants that does not have psychoactive effects. It has been shown to reduce anxiety and improve sleep quality in individuals with insomnia. However, it may cause side effects such as nausea and tiredness in some people. The recommended dosage is 25-175 milligrams per day, but more research is needed to determine the optimal dosage.
Magnesium
Magnesium supplements have been found to promote better sleep, as evidenced by studies from the National Institutes of Health Office of Dietary Supplements and the University of California, Berkeley.
Herbal Teas
Herbal teas, such as chamomile and passionflower, can be a great natural way to improve your sleep. These teas have calming and sleep-promoting properties that can help you relax and prepare for bed.
In addition to these natural sleep aids, it is important to maintain good sleep habits and practices. This includes things like limiting screen time before bed, avoiding working out within two hours of bedtime, and keeping the bedroom dark when sleeping.

Over-the-counter sleep aids
Over-the-counter (OTC) sleep aids are medications that can be bought without a prescription. They can be used to treat occasional sleeplessness or insomnia, but it's important to be aware of their potential side effects and risks. While OTC sleep aids are generally safe, they can cause daytime grogginess, blurred vision, confusion, constipation, and dependency if used over long periods. It is always recommended to consult a doctor or healthcare provider before taking any sleep medication to understand the options, benefits, and risks.
OTC sleep aids typically contain antihistamines, which work by blocking histamines—the substances in your body that cause alertness. Common antihistamines found in OTC sleep aids include diphenhydramine and doxylamine succinate, which help you fall asleep by decreasing histamine levels in your brain. However, antihistamines can also cause side effects such as blurred vision, confusion, and constipation, especially in older adults.
Melatonin is another popular OTC sleep aid. It is a synthetic version of a hormone naturally produced by the body to regulate the sleep-wake cycle. Melatonin supplements can help promote sleep and improve your sleep-wake cycle, but they are not regulated by the Food and Drug Administration as strictly as other medications. This means there may be some uncertainty about the accuracy of the listed ingredients.
CBD (cannabidiol), a derivative of the cannabis plant, is also available over the counter in many pharmacies. CBD does not contain THC, the compound responsible for the "high" associated with marijuana. It has been found to relieve anxiety, a common contributor to insomnia, and is being studied as a treatment for insomnia. However, there is currently no conclusive data on its effectiveness.
In addition to these options, there are also natural remedies and non-medicated methods to improve sleep. Soothing teas, valerian root, and cognitive behavioural therapy (CBT) can help promote sleep without the use of medication.

Prescription sleep medication
Sleep is essential for overall health and well-being, and sleep difficulties can significantly impact an individual's quality of life. While there are various over-the-counter (OTC) sleep aids and natural remedies available, prescription sleep medication is a stronger option that can be considered in certain cases of insomnia or other sleep disorders.
Different types of prescription sleep medications work in distinct ways to induce sleep. One common category is Benzodiazepines, which stimulate the production of a brain chemical called GABA (gamma-aminobutyric acid). This stimulation leads to sedation, muscle relaxation, and reduced anxiety, making it easier for individuals to fall and stay asleep. Z-drugs, such as zolpidem (Ambien) and eszopiclone (Lunesta), are another type of prescription sleep medication that works by slowing down brain activity, promoting sleep.
While prescription sleep medication can be effective in treating insomnia, it is important to be aware of potential side effects. Common side effects include daytime drowsiness, muddled thinking, dizziness, constipation or diarrhea, and muscle weakness. Additionally, there is a risk of rebound insomnia, where sleep difficulties may worsen if an individual stops taking the medication. In rare cases, some prescription sleep medicines may induce parasomnia, a sleep disorder characterised by disruptive behaviours such as sleepwalking or eating while still mostly asleep.

Non-drug therapies
Cognitive Behavioural Therapy (CBT): CBT is an effective tool for improving sleep and curing insomnia. It targets behavioural, cognitive, and physiological factors that perpetuate insomnia, aiming to modify and alter maladaptive behaviours and distorted beliefs about sleep. CBT can be delivered in various formats, such as individual or group therapy, or digitally-delivered self-help formats. Studies have shown that CBT has a positive impact on insomnia and associated symptoms.
Sleep Hygiene: This involves making adjustments to your sleeping habits and environment. For example, maintaining a cool temperature in your bedroom, avoiding large meals, alcohol, and caffeine before bed, and limiting exposure to bright light in the evening. These simple changes can have a significant impact on your sleep quality.
Natural Remedies: Some natural remedies that may aid sleep include warm milk, chamomile tea, and tart cherry juice. While there is limited scientific evidence for these remedies, they are generally safe to try and may be effective for some individuals. Additionally, natural supplements like melatonin and valerian can be helpful, but it is important to purchase them from a reputable source, as the dosages and ingredients may vary.
Exercise and Light Therapy: Regular exercise has been shown to have positive effects on both psychological and physical health, and it can also improve sleep. Light therapy has also been suggested as a treatment for sleep disorders, as exposure to light can impact sleep onset. For example, light exposure in the evening can delay sleep, while light exposure in the early morning can advance it.
