Canadian Tiredness Test

Did you have a bad night’s sleep last night? Are you feeling tired and not at your best? Take The Canadian Tiredness Test to find out just how alert you are!

Click your left mouse button as soon as you start to see the clock hand begin. Your reaction time indicates how tired you are.

  • If you do not click your mouse button quickly enough you will receive a “Oops – You Missed a Signal. Try Again!” message. After a short pause the clock will begin again.
  • If you click your mouse too quickly before the clock hand begins you will receive a “False Start” message. After a short pause the clock will begin again.
  • The test lasts approximately two minutes.
