Advanced Sleep Phase Syndrome (ASPS), also known as Advanced Sleep Phase Disorder (ASPD), is a sleep disorder that causes people to fall asleep and wake up earlier than desired. It is a circadian rhythm sleep-wake disorder, where the internal body clock runs earlier than usual. This can cause early evening sleepiness and early morning waking, resulting in insufficient sleep and insomnia. Light therapy, involving exposure to artificial light, is a recommended treatment for ASPS/ASPD. This therapy aims to reset the body clock by altering the timing of light exposure. For ASPS/ASPD, bright light therapy is typically administered in the late afternoon or early evening, with the light source brighter than normal indoor lighting.

Bright light therapy in the evening can delay the timing of circadian rhythms
Bright light therapy is a treatment for people with circadian rhythm sleep disorders. The human body has an internal clock that dictates when it is time to be asleep and when it is time to be awake. This internal clock controls the circadian rhythms in the body, including body temperature, alertness, and the daily cycle of many hormones. Circadian rhythms make you feel sleepy or alert at regular times every day.
Bright light therapy is used to manage circadian rhythm disorders such as delayed sleep phase syndrome (DSPS) and advanced sleep phase syndrome (ASPS). People with DSPS generally don't fall asleep until several hours after midnight and struggle to wake up in the morning, making it difficult to adhere to a normal work or school schedule. Bright light therapy is used to gradually shift sleeping patterns to what is considered normal.
For people with ASPS, bright light therapy is used to shift the sleep period to a later time. Evening use of bright light therapy is recommended for ASPS. This is because bright light stimulation in the evening can delay the phase of circadian rhythms, lengthening the sleep of early morning awakening insomniacs. The ideal timing of light exposure depends on the best approximation of the patient's circadian clock. Sleep specialists work with the patient to decide on the timing of the light exposure based on the patient's symptoms and life circumstances.
Light therapy generally fits into four basic groups: light boxes, visors, dawn simulators, and light-emitting glasses. Light therapy should always be used within the proper limits for intensity and time.

Light therapy involves using artificial light to change the body's natural circadian rhythm
Advanced Sleep Phase Syndrome (ASPS) is a sleep disorder that causes an individual's sleep-wake cycle to occur earlier than usual. People with ASPS struggle to stay awake until a "normal" bedtime, falling asleep in the late afternoon or early evening and waking up very early the following day. This can cause sleep deprivation and early morning insomnia, and can also affect their social life and work or school life.
Light therapy, also known as phototherapy, is a treatment that involves exposure to artificial light to regulate the body's natural circadian rhythm. The circadian rhythm is an internal biological clock that regulates sleep-wake cycles, as well as the release of hormones related to sleep, appetite, and core body temperature. Light is the strongest entraining agent of the circadian rhythm, and timed exposure to bright light is often used to treat circadian rhythm sleep disorders.
For people with ASPS, light therapy involves using artificial light to delay the body's natural circadian rhythm. This is achieved by exposing individuals to bright light in the late afternoon or early evening, shortly before their desired bedtime. The light should be brighter than normal indoor lighting and can be obtained from specialised light boxes or portable devices. It is recommended that individuals receive one to two hours of bright light therapy before bed, turning off the light 30 minutes before bedtime.
In addition to light therapy, other treatment options for ASPS include chronotherapy, behavioural changes, and the administration of melatonin. Melatonin is a hormone that helps to regulate the sleep-wake cycle, and it can be taken as a supplement to promote sleep. Combining light therapy with melatonin administration has been shown to be effective in treating circadian rhythm sleep disorders.

Light therapy should be administered early in the morning to reset the circadian rhythm
Advanced sleep phase syndrome (ASPS) is a condition where a person's sleep cycle starts and ends two or more hours earlier than usual. People with ASPS struggle to stay awake until a "normal" bedtime, often falling asleep in the early evening and waking up in the early morning. This can interfere with daily life and potentially cause sleep deprivation and early morning insomnia.
Light therapy is a treatment that involves exposure to artificial light to regulate the body's circadian rhythm. By mimicking natural sunlight, light therapy can improve the timing and quality of sleep for those with ASPS. The therapy typically lasts between 20 to 40 minutes, during which patients keep their eyes open to absorb the light, which is produced by a light box or lamp with an intensity of around 10,000 lux.
Light therapy should be administered early in the morning, ideally within an hour of waking up, to reset the circadian rhythm effectively. Morning light exposure helps suppress melatonin production, signaling to the body that it's time to wake up. In contrast, dimming the lights before bedtime and avoiding electronic devices can promote melatonin production and signal the body that it's time to sleep.
For ASPS, light therapy is used to gradually shift the sleep period to a later time. After the desired sleep schedule is attained, patients should maintain a fixed rise time and continue to use morning light exposure on most mornings, although the duration of light exposure can be shorter. Some patients continue the treatment indefinitely, while others reduce their daily treatment duration or frequency. The degree of success varies among patients.

Avoid bright light for an hour or two after waking up in the morning
Advanced Sleep Phase Syndrome (ASPS) is a circadian rhythm sleep-wake disorder, characterised by early evening sleepiness and early morning waking. People with ASPS struggle to stay awake until a "normal" bedtime and fall asleep early in the evening, only to wake up very early the following day.
Bright light therapy is a treatment option for ASPS, involving exposure to artificial light to regulate the body's circadian rhythm. By mimicking natural sunlight, bright light therapy can improve the timing and quality of sleep.
However, it is important to note that the timing of light exposure is critical for effective treatment. For ASPS, bright light therapy is typically recommended in the evening, before bedtime, to delay the patient's biological clock. Morning light exposure can be beneficial for some circadian rhythm disorders, but it may have the opposite effect for ASPS, reinforcing an earlier sleep schedule.
Therefore, to avoid reinforcing early waking, it is recommended to avoid bright light for an hour or two after waking up in the morning. This can be achieved by keeping the lights low in the morning or wearing light-preventing goggles or sunglasses, especially during the sunnier summer months.
Additionally, maintaining a fixed rise time, even on weekends and vacations, is important for stabilising the sleep schedule. Following good sleep hygiene practices, such as keeping a regular sleep schedule and avoiding caffeine, stimulants, alcohol, and other drugs, can also help improve sleep quality.

Melatonin, the sleep hormone, is released earlier in people with advanced sleep phase syndrome
Advanced Sleep Phase Syndrome (ASPS), also known as Advanced Sleep Phase Disorder (ASPD), is a circadian rhythm sleep-wake disorder. The condition is characterised by a sleep-wake cycle that operates two or more hours earlier than what is typical for most people. This means that people with ASPS struggle to stay awake until a "normal" bedtime and wake up very early in the morning, often unable to fall back asleep.
ASPS is caused by an earlier release of melatonin, the sleep hormone. Melatonin is the main hormone involved in the control of the sleep-wake cycle. It is produced by the body and can also be taken as an oral supplement. The production of melatonin is affected by light exposure. Bright light, especially in the morning, helps suppress melatonin production, signalling to the body that it is time to wake up. Conversely, dim light promotes melatonin production and signals to the body that it is time to sleep.
People with ASPS can, therefore, benefit from light therapy, also known as phototherapy. Light therapy involves exposure to artificial light to regulate the body's circadian rhythm. By mimicking natural sunlight, light therapy can improve the timing and quality of sleep for those with ASPS. Light therapy should be administered early in the morning, ideally within an hour of waking up, to reset the circadian rhythm effectively.
In addition to light therapy, there are other ways to regulate melatonin production and improve sleep for people with ASPS. It is recommended to dim the lights before bedtime and avoid electronic devices, as the blue light emitted by these devices can interfere with the body's production of melatonin. Sticking to the same sleep schedule every day and keeping the bedroom cool can also help improve sleep.
