QUESTIONNAIRE

The sleep process

The best time to sleep is at the point where the circadian sleep cues intersect with the peak pressure to sleep

10:00pm 7:00am

So what time should you go

to sleep?

If you have to get up

at 7am, then you

need to go to bed

somewhere between

9:30pm and 10:30pm

True or False

2. Sleep is as important to your

health as diet and exercise

The 24-hour day

Sleep is an active process. During sleep we are:

  • Growing taller and stronger
  • Making memories and establishing learning
  • Repairing our muscles and replenishing our energy
  • Processing and calming our emotions
  • Regulating our hormones so that we don’t increase our risk of gaining weight, getting heart disease, having high blood pressure, getting diabetes (the list goes on)

Not all sleep is the same

3. Watching TV, using your computer,

tablet or phone before bed can help

you get a good night’s sleep

The problem with TV,

computers, iPads, phones, etc

  • Electronic devices emit a certain type of light which tells our body it’s time to wake up
  • They can stop you going to sleep at a time that allows you to get enough sleep
  • They can give you “social jetlag” – feeling tired, grumpy and fuzzy headed because you don’t go to sleep the same time every night

How well do you sleep?

ACTIVITY
