Sleep is an essential part of our lives, but how much do we actually need? While there is no one-size-fits-all approach, research suggests that healthy young adults and adults with normal sleep patterns should aim for 7-9 hours of sleep each night. However, the amount of sleep we need varies throughout our lives, with teenagers aged 13-18 requiring 8-10 hours of sleep per day. It's important to note that some people claim to function well with less than 7 hours of sleep, but experts believe this is due to them becoming accustomed to the negative effects of sleep deprivation.

You can't train your body to need less sleep
While there is no one-size-fits-all approach to sleep, research suggests that for healthy young adults and adults with normal sleep, 7-9 hours is an appropriate amount. This amount varies throughout our lives, with teens aged 13-18 needing 8-10 hours of sleep per day.
There is a widely shared rumour that you can train your body to need fewer than 7-9 hours of sleep. However, this is a myth. According to experts, it is rare for anyone to need fewer than 6 hours of sleep to function. While some people might claim to feel fine with limited sleep, scientists believe it is more likely that they have become accustomed to the negative effects of reduced sleep. In other words, they are used to feeling sleep-deprived, but this does not mean that their body needs any less sleep.
Therefore, it is not possible to train your body to need less sleep. While some people may be able to function on less than 7-9 hours of sleep, this does not mean that their body has adapted to need less sleep. Instead, they are likely experiencing the effects of sleep deprivation, which can include feeling foggy or tired.

Teenagers should sleep for 8-10 hours per day
While there is no one-size-fits-all approach to sleep, it is generally recommended that teenagers between the ages of 13 and 18 sleep for 8-10 hours per day. This is because the amount of sleep we need varies throughout our lives, and this age group is still developing and growing, requiring more sleep than adults.
Research suggests that for healthy young adults and adults with normal sleep, 7-9 hours is an appropriate amount. However, this is not a strict rule, and some people may need less or more sleep than this. It is important to listen to your body and ensure you are getting enough sleep to function properly.
It is a myth that you can train your body to need fewer than 7-9 hours of sleep. While some people might claim to feel fine with limited sleep, scientists believe it is more likely that they have become accustomed to the negative effects of sleep deprivation. These effects can include feeling foggy or groggy, and it is important to recognise these signs and ensure you are getting enough sleep.
If you or your child is sleeping too much or too little, it is recommended to talk to a doctor to ensure you are getting the appropriate amount of sleep for your age and individual needs.

People who sleep for 6 hours or fewer become accustomed to the effects of sleep deprivation
While there is no one-size-fits-all approach to sleep, research suggests that healthy young adults and adults with normal sleep patterns should aim for 7-9 hours of sleep per night. However, it is important to note that some people might need less than 7 hours, while others might need more. For example, teens aged 13 to 18 years old are recommended to sleep for 8 to 10 hours per day.
Despite individual differences, it is a myth that you can train your body to need fewer than 7-9 hours of sleep. Although some people claim to function well with limited sleep, scientists believe that they have simply become accustomed to the negative effects of sleep deprivation. This means that even if someone feels fine with 6 hours or fewer of sleep, their body still needs more sleep.
The effects of sleep deprivation can be subtle and cumulative, impacting various aspects of our lives. For example, reduced sleep can affect our cognitive function, making it harder to concentrate and remember things. It can also impact our mood, leading to increased irritability and difficulty regulating emotions. Additionally, sleep deprivation has been linked to a higher risk of health problems such as obesity, heart disease, and diabetes.
When we consistently get less sleep than our body needs, we may not realise the full extent of the negative effects. Over time, we can become accustomed to feeling tired and foggy-headed, thinking it is our new normal. However, this does not mean that our body has adjusted to needing less sleep. Instead, we are simply tolerating the consequences of sleep deprivation.
It is important to prioritise sleep and aim for the recommended 7-9 hours per night. If you consistently feel tired or find it difficult to function during the day, it may be a sign that you are not getting enough sleep. Talking to a healthcare professional can help identify any underlying sleep issues and ensure you are getting the rest you need.
