| 0:00:04 | what do you know what are not the majority of your jet lagged without having |
|---|
| 0:00:07 | travelled anywhere |
|---|
| 0:00:09 | when individual travels overseas they don't satellites because the time of their internal clock no |
|---|
| 0:00:14 | longer matches with local time |
|---|
| 0:00:16 | a charming findings of the we and attempting to function at a time winner internal |
|---|
| 0:00:20 | clock ticking but they should be asleep |
|---|
| 0:00:24 | this is what is happening to many of his daily a right here in our |
|---|
| 0:00:26 | own time zone |
|---|
| 0:00:28 | i study the internal biological clock |
|---|
| 0:00:31 | and this plot that determines what you're morning percent were university |
|---|
| 0:00:35 | your degree morning the three evening that's |
|---|
| 0:00:37 | is stronger okay |
|---|
| 0:00:39 | what people perform best early in the day and prefer to go to sleep and |
|---|
| 0:00:43 | weak fairly early |
|---|
| 0:00:45 | whereas the slight majority of us early evening types |
|---|
| 0:00:47 | we preferred to go to ventilate we calculate and perform better later in today |
|---|
| 0:00:54 | unfortunately in today's twenty four hours society many of us are forced to be we |
|---|
| 0:00:58 | get times that of hoser internal clock |
|---|
| 0:01:01 | it's common these days that even take people although they can fall asleep and totally |
|---|
| 0:01:05 | they're forced away curly per social applications that just cooler work |
|---|
| 0:01:10 | there are several consequence is that represent the problem called social jet lag |
|---|
| 0:01:15 | the first consequence |
|---|
| 0:01:17 | is that this leads to chronic sleep restriction across the work week |
|---|
| 0:01:21 | the second consequence which i find particularly pertinent for students |
|---|
| 0:01:25 | is that these individuals are forced to learn early in the data which is the |
|---|
| 0:01:28 | time that the opposition with their internal clock |
|---|
| 0:01:31 | in it i seven found to have lower levels of academic achievement and this may |
|---|
| 0:01:36 | be due to social jet lag |
|---|
| 0:01:38 | my study will be the first to utilise the rate measures of chroma type in |
|---|
| 0:01:42 | order to do linear relationships between social chat like prototype and academic performance |
|---|
| 0:01:48 | questionnaires and diaries have been completed by over fourteen hundred i thought used you |
|---|
| 0:01:53 | preliminary analyses show with that evening type do have the highest levels of social gently |
|---|
| 0:01:58 | and that high levels of social dialect |
|---|
| 0:02:01 | correlate significantly with low class grade |
|---|
| 0:02:06 | this may suggest to has the school start times are too early for this population |
|---|
| 0:02:12 | my this is further where it's of the problems of social gently which may have |
|---|
| 0:02:16 | implications |
|---|
| 0:02:17 | as well for excellent performance but also for health issues |
|---|
| 0:02:22 | chronic sleep lots as well as chronic disconnect between internal and external time has been |
|---|
| 0:02:27 | linked with many mental and physical disorders such as cancers depression addition an obesity |
|---|
| 0:02:34 | as a society we should aim to be aware and accommodating of our natural biology |
|---|
| 0:02:39 | in order to weight the long term consequences of social don't like |

| 0:02:43 | thank you |
