Delayed Sleep Phase Syndrome (DSPS) is a common sleep disorder characterised by abnormally late sleep and wake times. People with DSPS often experience difficulty falling asleep before 1 a.m. or 2 a.m. and subsequently struggle to wake up at a socially acceptable time. DSPS is associated with psychiatric comorbidities, including depression, personality disorders, and functional difficulties. Treatment options for DSPS include adjusting your bedtime schedule, light therapy, and taking medications. Melatonin, a sleep-inducing supplement, has been found to be effective in advancing the circadian clock and improving sleep in patients with DSPS. It is recommended to take 1 to 3 milligrams of melatonin two hours before bedtime to promote sleep. However, it is important to note that melatonin supplements should be used in conjunction with good sleep practices, such as limiting screen time and maintaining a consistent sleep schedule.

Melatonin dosage: 1-3 milligrams, 2-3 hours before bedtime
Melatonin is a hormone that is produced naturally by the body to regulate sleep. It is possible to take melatonin as a supplement to aid with sleep issues, such as insomnia, jet lag, or delayed sleep phase syndrome.
If you are experiencing delayed sleep phase syndrome, melatonin may be an effective treatment. Delayed sleep phase syndrome is a Circadian Rhythm Sleep Disorder characterised by the inability to fall asleep and wake up at conventional times. Those with the condition often fall asleep well past midnight and wake up well past noon. This can cause marked sleep onset insomnia when individuals with the condition are made to conform to earlier sleeping times.
If you are considering taking melatonin supplements, it is important to first try to implement a good sleep routine. This can include committing to a consistent bedtime and wake-up time, limiting screen time two hours before bedtime, avoiding caffeine and alcohol later in the day, and sleeping in a dark room. It is also important to note that melatonin supplements should only be taken for a maximum of 13 weeks to treat short-term sleep problems in adults, unless otherwise advised by a specialist.
When taking melatonin, it is recommended to start with a lower dose, such as 1 to 3 milligrams, and take it two to three hours before bedtime. This can be increased if needed, although most people who take melatonin for sleep take between 1 and 5 milligrams. It is important to note that melatonin supplements have not been widely studied in children, and there is a chance that taking it could impact a child's hormonal development. Therefore, parents and caregivers may want to try other strategies for improving their child's sleep before turning to melatonin.

Melatonin advances sleep and the circadian phase in patients with delayed sleep phase syndrome
Delayed Sleep Phase Syndrome (DSPS) is a circadian rhythm sleep disorder characterised by abnormally late sleep and wake times. DSPS patients may find it difficult to fall asleep before 1 a.m. or 2 a.m. and often wake up well past noon. This sleep disorder is associated with psychiatric comorbidities, including depression, personality disorders, and psychological and functional difficulties.
DSPS patients can exhibit marked nervousness and a lack of control of emotional expression, which may worsen social withdrawal. This loss of social cues can further disrupt their circadian rhythm. The neurohormone melatonin, which is produced by the body, helps regulate the sleep-wake cycle or the circadian rhythm. Melatonin levels rise about two hours before bedtime, promoting a state of quiet wakefulness that helps prepare the body for sleep.
Studies have shown that melatonin, taken in the evening, can advance sleep and the circadian phase in patients with DSPS. In a randomised, double-blind, placebo-controlled trial, eight subjects with DSPS received either a placebo or 5 mg of melatonin daily for four weeks, with a one-week washout period in between. The subjects' sleep onset and wake times were significantly earlier during melatonin treatment compared to the placebo. Another study found that melatonin advances the circadian clock and sleep in patients with DSPS in a phase-dependent manner.
While melatonin supplements can be beneficial for DSPS patients, it is recommended to first establish good sleep practices and a consistent sleep routine. This includes limiting screen time, avoiding caffeine and alcohol later in the day, and keeping the bedroom dark and cool. Exposure to daylight during the morning and afternoon can also help regulate melatonin production. When taking melatonin supplements, it is generally recommended to start with a low dose of 1 to 3 milligrams two to three hours before bedtime.

Melatonin is the first-choice drug treatment for delayed sleep-wake phase disorder
Delayed sleep-wake phase disorder (DSPD), also known as delayed sleep phase syndrome (DSPS), is a type of sleep disorder called a circadian rhythm sleep disorder. It is the most frequently occurring intrinsic circadian rhythm sleep-wake disorder, with the highest prevalence in adolescence. People with DSPS are unable to fall asleep and wake up at conventional times. Sleep onset is usually well past midnight, and sleep ends well past noon. This can lead to marked sleep onset insomnia when individuals with DSPS are made to conform to earlier retiring times.
DSPS is characterised by a misalignment between the endogenous melatonin rhythm and the desired sleep time. This neurohormone regulates the timing of the central circadian pacemaker located in the Suprachiasmatic Nuclei (SCN). In people with DSPS, the melatonin onset is more than two hours before or after they fall asleep.
Melatonin is a hormone produced naturally by the pineal gland in the brain to regulate the sleep-wake cycle. Melatonin levels rise about two hours before bedtime, promoting sleep by putting you into a state of quiet wakefulness. For people with DSPS, melatonin treatment helps to correct this misalignment and improve sleep latency.
Melatonin is the first-choice drug treatment for DSPD, also known as DSPS. It is efficacious and safe for short-term use in youths, provided it is administered at the right time and in the right (minimal effective) dose. Melatonin treatment usually lasts for four weeks, improving sleep latency by 22–60 minutes. The recommended dosage for adults is 1 to 3 milligrams, while a low dose of 0.5 to 1 milligram is a common starting treatment for children. It should be taken three to four hours before bedtime.

Melatonin supplements are safe for short-term use and can increase sleep quality
Melatonin is a hormone that is produced naturally by the body to regulate sleep. Melatonin supplements are commonly used to treat insomnia and delayed sleep phase syndrome (DSPS). DSPS is a circadian rhythm sleep disorder characterised by abnormally late sleep and wake times. People with DSPS often experience difficulty falling asleep at a desired bedtime and trouble waking up at the desired time. This can lead to severe daytime sleepiness, memory issues, concentration problems, and behavioural or mood changes.
DSPS patients may also show marked nervousness and a lack of control of emotional expression, which can worsen social withdrawal and further disrupt their circadian rhythm. Depression is a common problem in patients with DSPS, and the sleep-wake cycle is one of many rhythms that can be disrupted in depressed patients.
Melatonin supplements can help people with DSPS fall asleep faster and improve their overall sleep quality. It is recommended to take 1 to 3 milligrams of melatonin two hours before bedtime. Melatonin supplements are generally safe for short-term use, but they should not replace good sleep practices. It is important to first establish a consistent bedtime and wake-up time, limit screen time before bed, avoid caffeine and alcohol later in the day, and maintain a cool, dark sleeping environment.
In addition to melatonin supplements, other treatments for DSPS include adjusting your bedtime schedule, light therapy, and taking medications. It is important to consult a healthcare provider before starting any treatment for DSPS.

Melatonin levels rise about two hours before bedtime
Melatonin is a hormone that is naturally produced by the body. It helps to regulate the body's sleep-wake cycle, also known as the circadian rhythm. This cycle occurs approximately every 24 hours and is influenced by the presence or absence of light. When it is dark, the body's pineal gland releases more melatonin, signalling to the body that it is time to relax and prepare for sleep. Conversely, when it is light, melatonin production decreases, helping an individual feel alert and awake.
For individuals with a normal sleep-wake cycle, melatonin production typically begins in the evening as the sun goes down, causing a gradual increase in sleepiness. Melatonin levels continue to rise, peaking about seven hours after sunset, which aids an individual in staying asleep through the night. As the sun rises and light is detected, melatonin levels drop, helping a person wake up and feel alert.
However, for those with Delayed Sleep Phase Syndrome (DSPS), the sleep-wake cycle is disrupted. DSPS is characterised by an inability to fall asleep and wake up at conventional times, with sleep onset usually occurring well past midnight and sleep offset past noon. DSPS is often associated with psychiatric comorbidities, including depression, personality disorders, and social withdrawal.
To address DSPS, melatonin supplements may be beneficial. Research suggests that melatonin supplements can help individuals with insomnia fall asleep faster and may have more significant benefits for those with DSPS. It is recommended to take a low dose of 1 to 3 milligrams two hours before bedtime. Additionally, creating optimal conditions for sleep is crucial. This includes minimising exposure to blue and green light from electronic devices, keeping the lighting low before bed, and getting exposure to natural light during the day.
While melatonin supplements can be helpful, it is important to prioritise healthy sleep habits, such as maintaining a consistent sleep schedule, limiting screen time, avoiding caffeine and alcohol, and ensuring a cool, dark, and quiet sleep environment.

Frequently asked questions
Delayed sleep phase syndrome (DSPS) is a sleep disorder characterised by abnormally late sleep and wake times. People with DSPS find it difficult to fall asleep at a desired bedtime and wake up at a desired time, often experiencing severe daytime sleepiness, trouble with memory, focus and concentration, and behavioural and/or mood changes. DSPS is also associated with depression and other psychiatric comorbidities.
Melatonin is a sleep hormone that helps regulate your body's circadian rhythm or sleep cycle. Taken in the evening, melatonin advances sleep and the circadian phase in patients with DSPS. Melatonin supplements can help people with DSPS fall asleep faster and improve sleep quality, how quickly they fall asleep and how long they sleep.
The most effective dose and time of administration of melatonin for DSPS are still unknown and require further research. In one study, participants were given either a placebo or 0.3 or 3.0 mg of melatonin. In another study, participants with DSPS and comorbid depressive symptoms were given 5 mg of melatonin. It is recommended that melatonin be administered at the correct time and in the minimal effective dose.
The most common side effects of melatonin supplements are drowsiness and headaches. Many people also experience vivid dreams and nightmares while taking melatonin. At higher doses, other side effects may occur. Overall, melatonin is considered safe and well-tolerated at low doses and when used for a short period of time. However, long-term use has not been extensively studied.
