Overview
Insomnia is a common sleep disorder characterized by difficulty falling asleep, staying asleep, or experiencing non-restorative sleep, leading to daytime impairment.
Insomnia is a prevalent sleep complaint that can significantly impact an individual's quality of life. It involves persistent difficulty with sleep initiation, duration, consolidation, or quality that occurs despite adequate opportunity for sleep, and results in some form of daytime impairment. This can manifest as fatigue, poor concentration, irritability, and reduced performance in daily activities.
Insomnia can be acute (short-term) or chronic (long-term). Acute insomnia often lasts for days or weeks and is typically related to stress, life changes, or temporary medical conditions. Chronic insomnia, lasting for three months or longer with at least three nights per week of sleep difficulties, can be more complex and may involve underlying medical conditions, psychological factors, or lifestyle habits. Understanding the potential causes is crucial for effective management.
While conventional treatments often involve cognitive behavioral therapy for insomnia (CBT-I) and sometimes medication, many individuals explore complementary and alternative approaches. These approaches often focus on improving sleep hygiene, managing stress, and utilizing natural compounds that may support relaxation and sleep. It is important to discuss any new treatments with a healthcare provider, especially if other health conditions are present or medications are being taken.
Tart cherry is a fruit rich in antioxidants and anti-inflammatory compounds, commonly used for its potential to support sleep and reduce inflammation, though robust scientific evidence is still developing.
Why it may help Insomnia: Valerian root contains compounds such as valerenic acid, which has been studied for its potential to modulate GABA-A receptors. This modulation may enhance the activity of GABA, a neurotransmitter associated with calming effects in the brain. By potentially increasing GABA's influence, valerian root may help in promoting relaxation, which is often beneficial for individuals experiencing insomnia.
As valerian root may cause drowsiness, individuals should exercise caution and avoid driving or operating heavy machinery after use, particularly when treating insomnia. It is generally not recommended for use during pregnancy or lactation. Caution is advised when combining valerian with other sedatives, alcohol, or medications metabolized by certain liver enzymes.
Why it may help Insomnia: Magnesium glycinate may support healthy sleep patterns due to magnesium's role as a cofactor in numerous biological processes, including those that modulate the nervous system. It appears to influence neurotransmitter activity, such as enhancing GABAergic tone and potentially modulating NMDA receptors, which could contribute to a calming effect. This calming action may facilitate falling asleep and maintaining sleep.
Typical dose
200-400 mg elemental magnesium before bedtime
Mechanism
Supports GABA function, relaxes muscles, and calms the nervous system.
Notes
Glycinate form is generally well-tolerated and less likely to cause digestive upset.
Evidence
moderate
While generally well-tolerated, high doses of magnesium may lead to gastrointestinal upset, such as loose stools. Individuals with kidney impairment should exercise caution and consult a healthcare professional before use, as issues with magnesium excretion could lead to accumulation. It may interact with certain medications, so professional advice is recommended.
Why it may help Insomnia: Chamomile contains compounds such as apigenin, a flavonoid, which may interact with GABA receptors in the brain. This interaction is thought to potentially promote relaxation and support the body's natural processes for initiating sleep. Animal and laboratory studies suggest these modulating effects on neurotransmitters.
Individuals with allergies to plants in the Asteraceae/Compositae family, such as ragweed, may experience allergic reactions to chamomile. Due to its potential sedative effects, caution is advised when combining chamomile with other sedatives, including hypnotic medications or alcohol.
Why it may help Insomnia: CBD oil appears to interact with the body's endocannabinoid system, which plays a role in regulating sleep. It may also influence serotonin 5-HT1A receptors, potentially contributing to anxiolytic effects that could support sleep. Additionally, its ability to reduce inflammatory cytokines and modulate TRPV1 receptors might help alleviate underlying discomfort that disrupts sleep patterns.
Sedation, often considered an undesirable side effect in other contexts, may be relevant for insomnia. Individuals taking other sedative medications should exercise caution due to potential additive effects. As quality varies, third-party tested products are recommended to ensure purity and potency.
Why it may help Insomnia: Lavender, particularly its constituents linalool and linalyl acetate, has been studied for its potential anxiolytic and sedative properties. These compounds may interact with the nervous system, potentially modulating neurotransmitter activity or ion channels, such as voltage-gated calcium channels, which could contribute to relaxation and improve sleep initiation or quality. These actions are thought to underpin its traditional use for promoting a calmer state.
When used topically, particularly in baths or massage oils for sleep, diluted lavender essential oil is generally considered safe, but skin irritation may occur in sensitive individuals. Oral forms of lavender should be used with caution, particularly if an individual is taking sedatives or other medications affecting the central nervous system due to potential additive effects. Pregnant or breastfeeding individuals should exercise caution and consult a healthcare professional before use.
Why it may help Insomnia: Lemon Balm may alleviate insomnia by modulating GABAergic neurotransmission, promoting relaxation and reducing the time it takes to fall asleep, thereby improving sleep quality.

How global health authorities view Insomnia.
The National Center for Complementary and Integrative Health (NCCIH) notes that while many people use natural products for sleep, scientific evidence for their effectiveness and safety varies. Melatonin has the most research support for certain sleep disorders, particularly jet lag and delayed sleep-wake phase disorder. Valerian root and chamomile are commonly used, but evidence for their efficacy in chronic insomnia is often inconsistent or limited. The Mayo Clinic emphasizes the importance of good sleep hygiene and cognitive behavioral therapy for insomnia (CBT-I) as first-line treatments, suggesting that natural remedies may play a supportive role but should be discussed with a healthcare provider. The World Health Organization (WHO) acknowledges the global burden of sleep disorders and

Sleep is important in maintaining the physiological function of the human body. Recently several studies have reported that preoperative sleep quality is associated with postoperative emergence delirium (ED) The ED is a common in pediatric patients undergoing general anesthesia with sevoflurane, but studies on the association of sleep quality have been rare. The investigators, therefore, aimed to investigate the relationship between postoperative delirium and pre and postoperative sleep quality in pediatric patients receiving strabismus surgery through this study
Sleep deprivation, which is a universal necessity, has serious physiological consequences.
Sleep disorders are among the most common health problems, and yet they are often neglected. The osteopathic treatment results in vasodilation, muscle relaxation and increased blood flow, resulting in improved range of motion, decreased pain perception and/or tissue changes. Thus, osteopathy ensures improved physical and mental health, which consequently helps patients with their sleep disorders.
The goal of this randomized controlled clinical trial is to evaluate if the implementation of an adjusted nighttime medical order protocol can improve sleep quality and stabilize physiologic parameters in hospitalized adult patients admitted to general wards.
The main questions it aims to answer are:
Does reducing non-urgent nocturnal medical interruptions increase total sleep time and REM duration? Does improving sleep continuity enhance subjective sleep quality and physiologic stability (heart rate, blood pressure)? Researchers will compare the intervention group (patients under an adjusted nighttime order protocol) with the control group (standard hospital care) to determine whether reorganizing nighttime medical routines improves objective and perceived sleep outcomes.
Participants will:
Wear a Fitbit Sense® device to continuously monitor objective sleep parameters across three hospital nights.
Complete the Pittsburgh Sleep Quality Index (PSQI) at admission and discharge to assess subjective sleep quality.
Undergo standard nighttime vital sign evaluations according to their assigned study protocol.
