The amount of sleep students get each night could be affecting their maths performance, new research claims.
A study by the University of Granada and Junta de Andalucia in Spain has found a link between students' performance in maths exams and how long they sleep each night.
The Spanish researchers reported that teenagers who sleep between six and ten hours per night scored significantly higher in maths tests than those who slept too little and those who slept too much.
Analysing a sample of 592 students aged between 12 and 19 at a secondary school in Seville, the academics found that adolescents who slept well got higher marks in maths tests.
Students were asked to answer two questionnaires that measured the quality of their sleep, levels of sleepiness and their sleep latency.
Published in the Journal of Clinical and Health Psychology, the study suggests that those who fall asleep quicker at night also performed better academically.
