How Awake Are You? Game Measures Sleepiness

Recently, I discovered Harvard’s Healthy Sleep website featuring the “How Awake Are You?” interactive game. In 5 minutes, it analyzes your wakefulness. Th game is an online adaptation of performance tests commonly used in research labs to examine the effects of sleep deprivation.

When I played, I felt a bit sleepy and the program picked up on this. Check it out

    I guess I am really asleep. I can not even find out how I am supposed to react. I tried space bar, return key, left/right arrows??

    OK, figured it out.

      Is it the spacebar? O.O

        Yes, the spacebar. Thanks, Nellie!

      Great! I’m so glad.

    This is really good boys kept asking me questions about their homework during this 5min test , so it would be the same distraction I would have if driving them somewhere.
    Even though I didn`t feel so tired during it, it did show up that I may start to feel tired at this time of the afternoon. !!

      Too funny about your boys distracting you. How true! Hope you didn’t hit anything. I did. 😉

    My avg reaction time was 0.32 with 0 accidents! Yay! :O)

      You must be wide awake, Becky! Good job. 🙂

    My avg reaction time was 0.30…which makes me safe? But, I had one crash.

    It was long and boring enough…that I could feel the threat of microsleeps creeping in….

    What’s better is that I barely slept 2 hours after my second dose this morning….so I’m still in a bit of a fog.

      Hi Dreamer: Thanks for checking this out! I agree, long and boring enough to make it realistic. 😉 Sending wakefulness and smiles your way, Julie

    Wasn’t very diagnostic for me. I am sleepy and have a migraine and yet I scored as safe with a reaction time of 29 seconds. I purposely did it with a migraine to see how much that would impair my functioning. I feel like I am thinking slowly but apparently it didn’t affect my reaction time.

      Thanks for trying it, Julie. Hope you’re feeling better!

    Awesome little program… Reaction time of 0.43 sec with 7 accidents. Sadly unsurprising given that I have a real track record of 4 major accidents and lots of close calls (prior to diagnosis, now I don’t drive and am far happier for it!). I feel like it would be an eye opener if something like this were a mandatory part of getting a driver’s licence – one round with no access to a cellphone, and once while using it to text/talk/read email/etc.

      Thank you for your comment! I agree, it’s a great tool for examining sleepiness.
