Daytime Slumber: Why Does My Son Sleep All Day?

Sleep is essential for teenagers to maintain good physical and mental health, build resilience, regulate their appetite, and stay at a healthy weight. Teenagers tend to want to go to bed later and wake up later due to a shift in their body's internal clock. While it may be okay for teens to sleep until late morning, sleeping all day could indicate an underlying issue. For instance, a 16-year-old boy who slept almost all day for over a month was diagnosed with Kleine-Levin syndrome, a rare condition affecting adolescents and young adults, characterized by excessive sleepiness lasting for weeks or months.

Circadian rhythm

The teenage body experiences a natural shift in its circadian rhythm, making it difficult for them to fall asleep before 11 pm. This is caused by a delayed release of melatonin, the hormone that is released in anticipation of darkness and prepares the body for sleep. Adolescents have a delayed release of melatonin, which causes them to become sleepy later at night, and predisposes them to remain asleep for longer in the morning.

The shift in the timing of the circadian rhythm is called "sleep phase delay". Before puberty, the body makes one sleepy around 8 or 9 pm. When puberty begins, this rhythm shifts by a couple of hours, and the body is ready for sleep around 10 or 11 pm. This is a natural part of growing up, and with some extra care, teens will adjust to the new sleep schedule.

However, teens often stay up late at night, throwing their body clocks off. They also tend to change their sleep schedules frequently, which can make them very sleepy when they should be wide awake. This can cause them to fall asleep at school or while driving, which is extremely dangerous.

To help your son adjust his sleep schedule, you can try the following:

• Encourage afternoon naps. A 30- to 45-minute nap before dinner is better than sleeping in, which throws off the body's sleep cycle.
• Ban tech from the bedroom. Using tech at night cuts into sleep time and the type of light emitted by screens suppresses the body's production of melatonin.
• Start the day in the sunshine. Having breakfast outside or by a sunny window helps regulate the body's biological clock, making it easier to wake up in the morning and fall asleep at night.
• Keep the lights dim in the evening. Open the curtains in the morning to let in bright light, to help keep the body clock set at the right time.
• Avoid caffeine after 4 pm.

Sleep disorders

There are many reasons why your son might be sleeping all day. Firstly, it is important to understand that teenagers have different sleep patterns from adults. Teenagers tend to want to go to bed later and wake up later due to their biological programming and the secretion of melatonin, which affects their circadian rhythms. Most teenagers need between 8 to 10 hours of sleep each night, with some requiring as little as 7 hours or as much as 11 hours.

If your son is sleeping during the day, it could be a sign that he is not getting enough sleep at night. This could be due to habits that interfere with good sleep, such as staying up late, napping during the day, or using electronic devices before bed. It is important to establish a consistent wake-up time and build a sleep schedule around it, with a reasonable bedtime.

However, if your son continues to sleep during the day despite having a regular sleep schedule, there could be other factors at play. One possible explanation is that he may be experiencing a sleep disorder. Sleep disorders can include conditions such as insomnia, sleep apnea, or narcolepsy. If you are concerned about your son's sleep habits, it is recommended to consult a healthcare professional, such as a sleep specialist, to rule out any underlying conditions.

In rare cases, excessive daytime sleepiness in adolescents could be a sign of Kleine-Levin syndrome, a condition characterized by bouts of excessive sleepiness lasting for weeks or months. This syndrome is more common in males and can also include symptoms such as fevers, muscle aches, and hyperphagia. However, it is important to note that this is a rare condition and there are typically no issues between episodes.

To help your son improve his sleep habits, encourage good daytime habits such as regular meals, physical activity, and limiting caffeine intake. Additionally, creating a sleep-friendly environment by minimizing electronic devices and screens in the bedroom can be beneficial.

Hormones

During puberty, the brain also matures, enabling teenagers to stay awake for longer periods. This biological programming makes teenagers inclined to go to bed later and wake up later.

Additionally, hormones can also influence sleep through their impact on mental health. Hormonal changes during puberty can contribute to stress, anxiety, and depression, all of which can disrupt sleep patterns.

Sleep environment

Light Exposure

It is important to regulate your son's exposure to light, especially natural light. Aim for him to get as much natural light as possible during the day, particularly in the morning. This helps the body suppress melatonin production in the morning and promote its release in the evening when it's time to sleep. Melatonin is a hormone that signals to the body that it's time to sleep. By regulating your son's exposure to natural light, you can help reinforce his body's natural sleep-wake cycle or circadian rhythm.

Screen Time and Electronic Devices

Electronic devices, screens, and the lights emitted by them can often disrupt sleep. It is recommended to avoid screens and electronic devices at least an hour before bedtime. This includes televisions, computers, and cell phones. Keeping your son's bedroom free of these devices and ensuring they are stored outside the bedroom at night can help reduce distractions and improve sleep quality.

Bedroom Environment

The ideal bedroom environment for sleep is one that is cool, dark, and quiet. Ensure your son's bedroom is maintained at a comfortable temperature, neither too hot nor too cold. Additionally, keep the lighting dim and minimize any sources of bright light. If necessary, consider using blackout curtains or an eye mask to block out light. Reducing noise or using white noise can also help create a peaceful sleep environment.

Daytime Habits

Encourage your son to engage in relaxing activities before bedtime, such as reading or listening to music. A warm shower can also promote relaxation. It is also important to avoid intense exercise in the hour before bed, as it may stimulate the body and make it harder to fall asleep.

Nutrition and Meal Timing

Nutrition and meal timing play a role in sleep quality. Ensure your son has a satisfying evening meal at a reasonable hour. Feeling too hungry or too full before bed can disrupt sleep. It is also recommended to limit the consumption of caffeine and sugary foods, especially in the late afternoon and evening. Caffeine can interfere with sleep, and its effects can last for several hours.

Sleep requirements

Sleep is a vital part of a teenager's life, and it is normal for them to want to sleep more than adults. Teenagers tend to want to go to bed later and wake up later due to a biological shift in their internal body clocks. This shift is caused by puberty hormones, which move the body clock forward by about one or two hours, making them sleepier later in the evening.

The average amount of sleep that teenagers get is between 6.5 and 7.5 hours per night, with some getting less. However, it is recommended that they get between 8 and 10 hours of sleep every night. This is because the developing brain of a teenager needs more sleep than that of a child or an adult.

If your son is sleeping all day, it could be a sign that he is not getting enough sleep at night. It may be beneficial to assess his sleep schedule and ensure that he is getting the recommended amount of sleep regularly. Maintaining a regular sleep schedule is essential, and napping in the early afternoon can also be beneficial.

If your son continues to sleep excessively during the day, it may be a good idea to consult a doctor, as it could be a sign of a sleep disorder or a rare condition such as Kleine-Levin Syndrome, which is characterised by bouts of excessive sleepiness lasting for weeks or months.
