8 . A short period of sleep taken during the day is known as a nap. Naps don’t just have benefits for adults at work, though. They could also help pupils to make the most of their school day. Studies have shown that a 20 to 30-minute “beauty sleep” makes people more alert and focused. This improves people’s ability to remember new information, which would help school children concentrate during lessons. Experts say that napping also improves brain functions, such as memory and the ability to complete difficult tasks.
The school day starts early, which means that pupils don’t always get enough sleep because there’s no chance to have a lie-in. Adding naptime during the school day would help exhausted pupils to make up for any sleep they’ve lost from getting up so early.
There are long-term benefits to taking a short nap, too. According to a recent study from University College London, the brains of people who have regular naps are bigger than those who don’t. People’s brains naturally shrink when they grow old, and the results showed that little sleeps can help people’s brains to age more slowly.
Although a nap can seem like a good idea, going to sleep for too long can actually make you feel worse. It’s not very pleasant to wake up from a daytime nap feeling confused and sleepy. Napping during the day can also have a negative impact on how well you sleep at night. This can create a cycle of not being able to sleep as well at night, leaving you feeling even more tired in the daytime. Sleep expert Dr Clete Kushida said, “It’s generally recommended to maximize sleep at night.”
Another consideration is that there really isn’t time in the school day for pupils to go to sleep. Some parents and teachers are concerned that it would cause children to miss too much lesson time. Pupils might take advantage of the system and use their need for a nap as an excuse to get out of lessons.
