Teens are at an important stage of their growth and development. Because of this, they need more sleep than adults need. The average teen needs about 8 to 10 hours of sleep each night to function best, to feel alert and well rested.

Most teens tend to have irregular sleep patterns across the week. Many teenagers prefer to stay at night until late hours and then find it difficult to wake up in the morning. They do not get enough sleep on weekdays and this may have a negative impact on them and on their learning. Then they sleep more in the weekend to compensate for this lack of sleep and occasionally they were described as young lazy kids.
