1. Daily sleep requirements for adolescents

Scientific Recommendations for Sleep Duration

The quality and duration of sleep becomes a critical health indicator during the formative years of a teenager's life. Most health organisations and experts consistently recommend that adolescents need 8 to 10 hours of sleep per day. This recommendation does not come out of thin air, but is based on numerous scientific studies and experimental data.


The different needs of teens versus adults and children

The need for sleep varies by age. Adults may only need 7 to 8 hours of sleep, while children may need more. However, during the teenage years, they have a higher need for quality sleep because their bodies and brains are developing rapidly.


Supporting Physical and Mental Development

During the teenage years, the body undergoes tremendous changes, including but not limited to height growth, weight gain, and the development of sexual organs. All of this requires large amounts of energy and growth hormones, which are produced and secreted during deep sleep.


Prevent Chronic Fatigue and Mental Stress

Lack of adequate sleep not only affects the physical health of teenagers, but also has a negative impact on their mental state. Chronic fatigue, lack of concentration, and mood swings can all be a direct result of sleep deprivation.


Establish a good routine

Teenagers are at a critical time to develop good habits. Getting enough sleep can help them better control their emotions and improve their learning efficiency, which also lays the foundation for a healthy routine in adulthood.


To sum up, the 8 to 10 hours of sleep that teenagers need daily is by no means an arbitrary figure, but a recommended value derived from rigorous scientific research. This time not only supports their rapid physical growth, but also affects their mental health and daily performance. Therefore, for the overall health of our young people, we must take this recommendation seriously and implement it.

2. Impact of sleep on adolescents' physical development


Growth Hormone and Physical Development

When you think of adolescents and sleep, the first thing that may come to mind is growth hormone. Yes, it is true that during deep sleep, the body secretes large amounts of growth hormone. This hormone directly stimulates bone and muscle growth, helping teens make the physical transition from child to adult. So, by making sure your teen gets enough quality sleep, you are actually directly contributing to their physical development.


Immune system: sleep recharges your "body guard"

During adolescence, the immune system is still developing and improving. Getting enough sleep gives the body time to make more white blood cells and antibodies, which increase resistance to external viruses and bacteria. In other words, a good night's sleep "recharges" the immune system of adolescents, making them more effective in fighting off diseases.


Endocrine system: regulates weight and mental health

Getting enough sleep also normalises hormone levels in teens, including those related to appetite and mood. Studies have shown that lack of sleep can lead to weight gain and mental health problems. Therefore, ensuring adequate sleep can help teens maintain a healthy weight, as well as help them better manage their emotions.


Cardiovascular health: a role not to be ignored

Adequate sleep is also associated with cardiovascular health. Studies have found a correlation between sleep deprivation and cardiovascular disease. When teens get enough sleep, their cardiovascular system gets the rest and repair it needs, which is important for cardiovascular health in the long run.


Muscle Recovery and Sports Performance

Quality sleep is even more essential for teens who are athletic or involved in physical activity. During sleep, muscle tissue is repaired and rebuilt, which improves performance and reduces the risk of injury.


3. Relationship between sleep and adolescent learning and memory

Sleep quality directly affects learning efficiency

Teenagers are in a stage of high pressure and heavy school work. Quality sleep not only contributes to their physical health, but also has a direct impact on their learning efficiency. Many studies have shown that adequate sleep can improve adolescents' information processing ability and enhance learning efficiency.


Correlation between memory consolidation and deep sleep

When adolescents enter a deep sleep state, the brain will automatically organise the information learned during the day and convert short-term memories into long-term memories. This process is called "memory consolidation". In other words, deep sleep not only helps to store information, but also makes memories stronger.


Lack of Sleep Leads to Loss of Concentration

Lack of sleep affects a teenager's ability to concentrate and focus, which in turn reduces their performance in school and other activities. Studies have proven that teens who lack enough sleep perform poorly in school and are more likely to suffer from memory loss and lack of concentration.


Matching Sleep Cycle with Study Time

To ensure that information is absorbed and stored efficiently, it is recommended that teens schedule adequate sleep after peak learning periods. Doing so not only improves learning the next day, but also helps in the formation of long-term memory.


Improve sleep quality to optimise learning outcomes

By adjusting their routine, improving the comfort of their sleep environment, and avoiding the use of electronic devices near bedtime, teens can effectively improve the quality of their sleep. Remember, quality sleep is the key to efficient learning and excellent memory.

4. Sleep and Adolescent Emotional Management

Sleep quality directly affects mental health

Sleep is not only a time for the body to rest, but also a critical time for the brain to repair and adjust itself. Good quality sleep helps balance neurotransmitters in the brain that are responsible for emotional and mental health, such as dopamine and serotonin. When teens get enough quality sleep, they are more likely to maintain a stable mood and avoid developing anxiety, depression, or other psychological problems.


Lack of Sleep Triggers Emotional Outbursts

Conversely, sleep deprivation can lead to mood swings and loss of control. This not only affects a teen's relationships with family, friends, and classmates, but can also lead to more serious psychological problems, such as depression or anxiety. Lack of sleep reduces activity in the prefrontal lobe of the brain, the area that controls emotions and decision-making, leading to impulsive behaviour and unstable emotions.


Sleep and the Stress Response

The teenage years are already stressful enough with school pressures, social pressures and physical changes. A good quality of sleep improves an adolescent's resistance and ability to cope with these stressors. Getting enough sleep reduces the production of cortisol (a stress hormone), making it easier for teens to face difficulties and challenges with a calm mind.


How to Improve Teenagers' Sleep Quality for Better Mood Management

Improving the sleep quality of teenagers is not only the responsibility of parents and educators, but also the responsibility of society. Taking the following steps can be effective in improving the quality of sleep for teens:


  • Establish a consistent routine: Make sure your teenager goes to bed and wakes up at the same time every day.


  • Create a good sleep environment: Reduce noise and lights, and provide comfortable beds and bedding.


  • Limit caffeine and sugar intake: especially in the hours leading up to bedtime.


  • With these science-based sleep solutions, we can not only improve our teens' physical health, but also help them develop a more stable, healthy emotional and mental state.


Take Timely Action

Having recognised the importance of sleep for your teen's emotional management, now is the time to take action. Whether you're a parent, educator, or someone interested in your teen's health, you can help with the above suggestions. Remember, improving the quality of sleep is a critical step towards better emotional management.

5. Why is sleep deprivation common among adolescents?


Academic stress exacerbates sleep deprivation

Academic stress, one of the leading causes of sleep deprivation, affects almost all teens. College entrance exams, final exams, and daily academic tasks cause teens to sacrifice sleep time to prepare. Not just the coursework itself, but parents' and teachers' expectations of excellent grades also increase teens' psychological stress, further affecting their sleep.


Social activities and electronic devices consume time

Social activities and electronic devices are also important factors in the prevalence of sleep deprivation among teens. Teenagers like to spend their evenings chatting or gaming with friends, causing them to delay going to sleep. The blue light emitted by mobile phones, TVs and computers may also suppress the production of melatonin, a hormone that helps regulate a person's routine.


Misguided societal beliefs and values

Society's common belief that "busy is productive" inadvertently affects teenagers. They believe that staying up late is the same as working hard, which leads them to neglect the importance of sleep for their physical and mental health.


Irregular Routine

Irregular work and rest habits are also part of the problem. Many teens stay up all night or stay up late on weekends or holidays, and this "social staying up" breaks their normal routine, further affecting the quality of sleep they get during the workday.


Influence of family environment

The family environment also plays an important role. Sometimes parents don't pay attention to their children's sleep needs, or the home itself is not conducive to sleep due to noise, brightness, and other factors.


6. Improving Teenagers' Sleep through Environment and Supplies


Importance of the sleep environment

Sleep environment directly affects the quality of sleep. A quality sleep environment not only allows teenagers to fall asleep faster, but also improves the quality of sleep, thus promoting healthy physical and mental development.


Optimise bedding to improve sleep experience

Bedding such as mattresses, pillows and sheets have a direct impact on a person's sleep experience. Choosing a mattress that is suitable for teenagers can greatly improve their sleep quality. As a professional mattress manufacturer with 25 years of experience, Suilong focuses on combining ergonomics and bioscience to provide scientific sleep solutions.


Create a quiet environment

Noise is a key factor in sleep quality. You can prepare a quieter environment for your teenager, such as using soundproof windows or earplugs to minimise the impact of external noise on sleep.


Adjust indoor temperature and humidity

Room temperature and humidity are also important factors that affect the quality of sleep. It is usually recommended to maintain the room temperature at 18-22 degrees Celsius and keep the relative humidity between 40-60 per cent.


Control light to help deep sleep

The right amount of light can help your teenager enter the deep sleep stage faster. You can use heavy curtains or eye masks to minimise light disruption to sleep.


Add soothing music or white noise

Soothing music or white noise can help your teenager fall asleep faster. You can have a special sleep music list for them or use a white noise machine to create a more peaceful environment.


Action plan: Change starts now

Start optimising your sleep environment and supplies today. A small change can have an unexpected positive impact. Whether it's choosing a suitable mattress or adjusting the temperature and humidity in your room, every step is worth trying and practising.

7. Practical Advice: How can I help my teenager to sleep better?

7.1 Set a regular routine

Let's start by setting a regular routine. A regular routine not only improves your teenager's physical health, but also reduces psychological stress. It is recommended to go to bed at the same time and wake up at the same time every day to regulate the body clock and promote quality sleep.


7.2 Gradually reduce light and noise before going to sleep

Reducing the impact of light and noise can help the brain relax and enter the deep sleep stage more easily. One effective way to do this is to avoid using electronic devices, especially those that emit blue light such as mobile phones and televisions, for an hour before bedtime. Also, consider using earplugs and eye masks to block out outside noise and light.


7.3 Encourage appropriate physical activity

Physical activity has been shown to improve sleep quality. It is recommended that adolescents engage in moderate exercise at least two hours after dinner, but avoid high-intensity exercise close to bedtime as it may make them more excited and less likely to fall asleep.


7.4 Focus on dietary management

Ensuring that your teenager eats sensibly can also help to improve sleep. Avoid drinks and foods that are high in sugar and caffeine, especially in the evening. Vegetables, fruits and Omega-3 rich foods such as fish can provide the nutrients that the body needs to help promote better sleep.


7.5 Setting up a relaxation routine before going to sleep

A pre-sleep relaxation routine lets the brain know that it is time to prepare for rest. This routine can include deep breathing, a warm shower or reading a relaxing book.


7.6 Education and Communication

Making your teenager aware of the importance of sleep and how to improve it is the key to solving the problem. An open discussion with them about the importance of sleep can eliminate any misconceptions or stigmatisation of the issue.


7.7 Professional Medical Consultation

If there is still no significant improvement in your teenager's sleep problem after trying all the above suggestions, it is advisable to seek professional medical counselling. More detailed examination and diagnosis may be required to find out the root cause of the problem.


Understanding the sleep needs of teenagers is a pivotal step towards a healthier lifestyle. Don't underestimate the power of a good night's sleep. Take action now and set your teen on the path to better well-being.
