Is 5 hours enough sleep for an 11 year old?

No, 5 hours is not enough sleep for an 11-year-old child.

According to the National Sleep Foundation, children aged 6-13 need an average of 9-11 hours of sleep per night. Getting enough sleep is crucial for children's physical and mental well-being and affects memory, concentration, ability to learn, behaviour, and overall health.

Long-term sleep deprivation can also contribute to serious health problems in the child later in life, including obesity, high blood pressure, heart disease, and diabetes.

Therefore, it is highly recommended that parents ensure their 11-year-old children receive about 9-11 hours of sleep every night.
