Children who sleep less than 9 hours every night have difficulty in acquiring knowledge at school. This is a study by scientists from the University of Barcelona (Spain).

Scientists conducted the study by comparing the number of hours of sleep each night with the results of 142 primary school students.

The results showed that the majority of 6 and 7-year-olds slept less than 9 hours in the evening were less likely to communicate and had difficulty solving problems. Students who sleep less often experience more spelling and grammar errors and also have poorer memory.

Dr. Ramon Cladellas, head of the study, said: 'Most children who sleep less than 9 hours every night are often affected by intellectual development because lack of sleep makes the brain not enough time to rest and recovery. '

Scientists say that more and more children who are deprived of sleep are often left behind by electronic devices such as TVs, computers and video games in their bedrooms. This makes children play and stay up late.

Dr. Russell Foster, an expert in neuroscience at Oxford University, said that the best time for Primary students is to sleep 9.5 hours every night. When getting enough time, children will easily solve difficult problems at school.

Dr. Foster advises adults who need at least 6.5 hours to 8.5 hours of sleep each night. People who sleep less than 5 hours / night may have problems concentrating and the brain processes slowly the next day.
