Sleep is an essential part of our lives, but how much do we really need? Experts recommend that adults get between seven and nine hours of sleep a night, while teens should aim for eight to ten hours. During sleep, our bodies repair tissues, boost our immune system, and build up energy for the day ahead. However, the quality of sleep is also important. Did you sleep straight through, or did you wake up during the night? These factors can impact how well-rested we feel, even if we've slept for the recommended number of hours.

Sleep quality
It's recommended that adults sleep between seven and nine hours a night. However, sleeping more than nine hours a night is not necessarily harmful and may be helpful for young adults, people who are recovering from sleep deprivation, and people who are sick.
Teens aged 13 to 18 should sleep for eight to ten hours per day.
During the third stage of sleep, your brain waves slow down and it's harder for you to wake up. This is when your body repairs tissues, works on growth and development, boosts your immune system, and builds up energy for the next day.

Sleep stages
Sleep is divided into four stages, each with a unique function and impact on the body. The first stage is light sleep, where the body transitions from wakefulness to sleep. This stage is characterised by slow eye movements and muscle relaxation. The second stage is when the body prepares for deep sleep, with heart rate and breathing regulated and body temperature dropping. The third stage is deep sleep, where brain waves slow down and it becomes harder to wake up. During this stage, the body repairs tissues, boosts the immune system and builds up energy for the next day. The fourth stage is rapid eye movement (REM) sleep, which usually starts about 90 minutes after falling asleep. REM sleep is associated with dreaming and memory consolidation.
The amount of sleep needed varies with age. Teens between 13 and 18 years old should aim for 8 to 10 hours of sleep per day. For adults, the recommended amount is between 7 and 9 hours of sleep per night. Sleeping less than 7 hours a night may increase the risk of health issues. However, sleeping more than 9 hours may be beneficial for young adults, those recovering from sleep deprivation, and people who are sick.
It is important to consider sleep quality in addition to the number of hours slept. Sleep quality refers to how well one sleeps throughout the night, including factors such as whether one sleeps through or wakes up periodically. Individual differences in sleep needs also exist, with some people functioning well with fewer hours of sleep than others.

Sleep recommendations for adults
Sleep is an essential part of a healthy lifestyle. Experts recommend that adults sleep between seven and nine hours a night. Sleeping less than seven hours a night may lead to more health issues than those who sleep seven or more hours.
However, it's not just about the number of hours you sleep; sleep quality is also important. For example, did you sleep straight through the night, or did you wake up during the night? If so, did it take you a long time to fall back asleep?
The third stage of sleep is "deep sleep", when your brain waves slow down and it's harder for you to wake up. During this period, your body repairs tissues, works on growth and development, boosts your immune system, and builds up energy for the next day.
Teens aged 13-18 years old should sleep eight to ten hours per day.

Sleep recommendations for teens
Sleep is an essential part of our lives and it is important to get the right amount. Experts recommend that adults sleep between 7 and 9 hours a night. However, teens aged 13 to 18 years old should be getting 8 to 10 hours of sleep per day. This is because sleep is when our bodies repair tissues, work on growth and development, boost our immune systems, and build up energy for the next day.
It is important to note that the quality of sleep is also important. This means considering how well you sleep during the night. Did you sleep straight through? Or did you have periods where you woke up? If so, did it take you a long time to fall back asleep?
If you are a teen and you are struggling to get the recommended amount of sleep, there are a few things you can try. Firstly, try to establish a bedtime routine. This might include activities such as reading, listening to calming music, or practising meditation or deep breathing exercises. Secondly, create a sleep-friendly environment by making sure your bedroom is cool, dark, and quiet. Finally, limit your exposure to screens before bed, as the blue light emitted by smartphones, tablets, and computers can interfere with your sleep.
If you are concerned that you or your child is sleeping too much or too little, it is important to talk to a doctor. They will be able to provide personalised advice and recommendations.

Sleep recommendations for children
Sleep is essential for the body to repair tissues, work on growth and development, boost the immune system, and build up energy for the next day. While adults should aim for 7-9 hours of sleep per night, the amount of sleep children need depends on their age.
For teenagers between the ages of 13 and 18, it is recommended that they get 8 to 10 hours of sleep per day. This is because teenagers are still growing and developing, and adequate sleep is crucial for their physical and mental well-being.
For younger children, the recommended amount of sleep varies with age. Sleep experts consider naps to be appropriate for children under the age of 7. The recommended hours of sleep, including naps, for different age groups can be found online or by consulting a healthcare professional.
It is important to note that sleep quality is also crucial. Sleeping straight through the night without waking up is ideal, but if you do wake up, it is important to fall back asleep quickly. If you or your child is struggling with sleep, it is recommended to consult a doctor for advice and guidance.
