  1. CAFFEINE EFFECTS ON SLEEP BY ANDREW MCGRATH & ANDREA DELLA LIBERA

  2. Does it really effect your sleep? • The answer to this question is varied from person to person • Several people think that they will sleep less while others are not affected. • When asked, a female nurse from MC hospital said that caffeine does effect sleep, but a male nurse said the opposite.

  3. WHAT IS CAFFEINE? It is a bitter, white crystalline xanthine alkaloid and a stimulant drug that can be found in seeds leaves or fruit of certain plants (coffee, tea, cocoa) or can be handmade.

  4. CAFFEINE AND THE BRAIN Everybody knows that caffeine has various effects on the brain: it`s a stimulant, that increases intellectual abilities, but it can also influence people`s mood and affect the ability of sleeping, causing insomnia.

  5. BUT… Many experiments have shown how caffeine affects the brain but in real life it seems to be false, because some people can quietly drink coffee or energy drinks without problems, even before sleeping.

  6. EXPERIMENT The purpose is to examine the effects of caffeine, to verify if it really affects the ability of sleeping. • Null Hypothesis: Caffeine doesn’t change people’s ability of sleeping • Alternative hypothesis: Caffeine acts as a stimulant and causes insomnia: people can hardly all asleep

  7. METHOD Note: Sleeping routines are taken in effect when the experiment is given. We choose the ‘Average’ people based on the survey information we have received.

  8. We are giving 80-100 surveys randomly between our senior and junior classes. • We will pick a select 20 volunteers to partake in the experiment based on the surveys (10 male and 10 female) to be tested for two nights. • The volunteer must then fill out a parent consent form before drinking the energy drink.

  9. On the first night we will register their heart rate before they have consumed any caffeine • After their heart rate has been measured the volunteer will then sleep as they would normally. • The second night the volunteers will drink a high caffeinated drink and have heart rate measured.

  10. After this they will again go to sleep like they would normally. • Then we will give a questionnaire asking about their previous nights sleep.

  11. Interesting Discoveries • We have now 80 surveys completed. • Out of the 80 surveys finished, 9 out of 10 people use their mobile device before going to bed at night. • 9 out of 10 people also said they sleep for about 8 hours every night. • 8 out of 10 people wake up between 6:30 and 7 AM. • 8 out of 10 people also say they have no difficulty falling asleep on a daily basis.
