#scichallenge2017 #scienceincypriotschools A study of the sleeping habits of adolescents in a school in Cyprus

  1. 1. A STUDY OF THE SLEEPING HABITS OF ADOLESCENTS IN A SCHOOL IN CYPRUS By Christos Pantazis, Age 13, Med High School, Larnaca, Cyprus.
  2. 2. INTRODUCTION Like most teenagers I have been told by my mother on numerous occasions that I do not sleep enough, that I go to bed too late and I should not sleep with my mobile phone by my side. I decided to see if my fellow students had the same habits as I have and I was curious to see if these were different with each age group. I also wanted to research if there was a scientific basis behind the things we are told by our parents and guardians .
  3. 3. METHOD I created a survey which asked questions relating to sleep and behaviours before sleeping. I made 100 copies and gave them to teachers to give randomly to students at my school. Our school is an international school with students from over 23 countries therefore I believe this will cancel out any differences due to culture or nationality. The test was anonymous and when completed I collected all the data. (photo of year 6 pupil completing my survey) •
  4. 4. RESULTS Out of the 100 copies of the survey that I gave out, 83 were completed. The age groups and sexes were as follows. Table below shows the results from Q1-How old are you? and Q2- Are you male or female? AGE (years) MALE FEMALE TOTAL 12 6 8 14 13 12 11 23 14 3 7 10 15 2 3 5 16 6 7 13 17 8 4 12 18 1 5 6 TOTAL 38 45 83
  5. 5. Q3) On average how many hours do you sleep on a school night? Q4) On average how many hours do you sleep at the weekend? 0 2 4 6 8 10 12 13 14 15 16 17 18 Averagenumberofhourssleep. Age (years) Average number of hours sleep on a school night compared to a weekend night. School Night Weekend night
  6. 6. • • From our results it can be seen that 15 year olds sleep the most (8.6 hours) and the least 16 year old (5.7 hours). • All students sleep more at the weekend than they do during the week. • The largest difference is 18 year olds with a difference of 3.1 hours. • The average hours of sleep for all students together during a week night is 7.54 hours and at the weekend it is 8.7 hours. Discussion The University of Stamford (reference 1) says that adolescents should sleep on average 9.15 hours a night. From my study none of the age groups sleep that amount in fact the 16 year old group sleeps 3.45 hours less than this an evening! An article from UCLA health (reference 2) says this could be because of changing bodies, busy schedules and social life and a wrong view of sleep.
  7. 7. Q5 ) On average what time do you sleep on a school night? 0 5 10 15 20 25 7 p.m 8 p.m 9 p.m 10 p.m 11 p.m 12 p.m 1.0 a.m 2.0 a.m 3.0 a.m Numberofstudents. Average time students go to sleep. Average time students go to sleep on a school night.
  8. 8. • My results show that most students sleep at 10 o’clock followed by 11 o clock. • A couple of students went to bed at 7 o’ clock and one student regularly goes to bed at 3 in the morning! Discussion It has been seen that the circadian rhythms in adolescents are different to those in other groups and so mostly make pupils want to go to bed later but at the same time wake up later (reference 2 and 3). These are like biological clocks that tell us what to do.
  9. 9. Q6) Do you sleep with your mobile phone next to you? (within 1 meter of your head) 0 20 40 60 80 100 12 13 14 15 16 17 18 Numberofstudents(%) Age (years) Percentage of students who sleep with their mobile phones within 1m distance from their head.
  10. 10. I was shocked to see that 51.8% of the students in our school sleep with their mobile phones next to them and that 100% of all 17 year olds surveyed slept with their phones next to them. Discussion There has been a lot of press regarding the effects of phones next to our heads. One theory says that it suppresses the production of melatonin a hormone which we produce at night and effects our sleep patterns but is believed to have other properties such as anti-cancer properties (reference 4). It is mainly the LED light produced by the screens that has these effects.
  11. 11. Q7) What do you usually do during the one hour before you sleep? I prepared a list of the activities recorded in this box with the most popular first and the least popular last. These were: • Social media (phone/IPad) • Homework • T.V/ movies • Video games • Eat • Read books • Shower • Draw • Exercise • Meditate • Other
  12. 12. Discussion Once again my results show how much adolescents rely on electrical devises for entertainment before they go to sleep which again can affect the melatonin levels. Also many of these activities stimulate and keep you awake such as playing video games , where as reading is more relaxing. • •
  13. 13. Q8) Which time of the morning do you feel most ‘awake’ and most focused? 0 5 10 15 20 25 5 a.m 6 a.m 7 a.m 8 a.m 9 a.m 10 a.m 11 a.m 12 p.m Never Numberofstudents Time Time of morning students feel most 'awake'.
  14. 14. Discussion Most schools in Cyprus start at 7.30 so as to finish by 1.30. This is due to the high temperatures in the spring and summer in the early afternoon . There has been much discussion as to whether the time for school and work should change to suit the time people feel most feel awake. This was tried out at a school in England which began at 1.30. (reference 5) instead of 9 o’clock and there is much discussion as to whether other schools should change.
  15. 15. Q9) Do you think that you get sufficient sleep for your age? 0 10 20 30 40 50 60 70 80 12 13 14 15 16 17 18 Numberofstudents(%) Age Percentage students who believe they receive sufficient sleep.
  16. 16. Discussion • Roughly half the students questioned (49%) said yes they get sufficient sleep. • Surprisingly 74% of 17 year olds said that they got enough sleep and yet the hours they slept were the second lowest . • Only 20% of 15 year olds said they received enough sleep and yet they slept the most hours out of all the groups!
  17. 17. GENERAL CONCLUSION I generally think that what our parents and guardians say to us about sleeping is correct. We do not sleep enough and technology is most probably having a negative effect on us although more research is needed. Maybe we should change our school hours to suit our circadian rhythms .This however is an age in which our bodies and brains are changing and we often cannot help when we feel tired or sleepy. •
  18. 18. • Limitations of my investigation and further investigations. • The results would be more reliable if I had more students. Some age groups were small especially the 15 year old group. • I would be interested to see the sleeping habits in younger age group and differences with the season e.g summer with winter. • It would be interesting to investigate the effects of the lack of sleep on school performance. • • References • • • • causes-sleep-problems/ • later-start-to-the-school-day-be-the-most-useful-educational- reform-of-all-9695407.html
