Do people really have internal alarm clocks?

Updated on December 4, 2010
Internal Alarm Clock?
Internal Alarm Clock?

My wife is not an early riser. She had volunteered to man the reception table at a YMCA-sponsored running event in Charlotte. The only problem was that she was told to be there at 5:45 AM on a Saturday morning.

Doing the math, she realized that if she took a late bath and got everything ready to go that she could just make it, if she got up no later than 5:00 AM.

Knowing that she was trying to cut it a little too close for my liking, I told her that I would get up at 4:45 to make sure that the coffee was fresh and to make sure that she didn’t oversleep.

Sometime after midnight I fell asleep on the couch. The last thing I remember, I had been watching Charlie Rose interviewing some author about the state of the economy and its future. I had fallen asleep before I had had a chance to set the alarm clock.

At exactly 4:45 AM I suddenly woke up; wide awake and ready to go. The reason I knew it was 4:45 was because that was the time that was displayed on a digital clock on the entertainment center in our living room.

I got up from the couch and fired up the coffee pot and told Carla it was time to get with it. She did whatever she had to do and went out the door with just enough time to make it.

Now comes the question that is the seed for this article. Do we have some sort of internal alarm clock? How did my body know that it was exactly 4:45 AM and that I needed wake up right now?

Have you ever experienced a similar event, when you woke up without the aid of an alarm clock, at exactly the time that you needed to?

      DiamonRN - How kind of you to assist your wife. I have on occasion woken up about 15 minutes before my alarm went off, but I am not very consistent about it (I also do not get up at the same time each morning, which seems to help some people.)

      I have had friends who consistently wake up just before the alarm goes off. Amazing that our sleeping or subconscious minds can do that. Interesting Hub. Thanks.

      Very interesting! When I don't set the alarm, I wake up at the same time during the week! Hmmmm.... Voted-UP!

      It's happened for me, but not on the mark, usually much earlier than when I 'have' to be up.

      As soon as I read the title of your hub I felt attracted to it. In many occasions through my life I was amazed about how I woke up few minutes before I set on my mind to rise next day in the morning at a certain time. The felling is marvelous. It work best even more when I plan to rest at night not too late and not too tired along with a chamomile tea. I enjoy your hub.

      I believe that I have internal alarm clock as well, because I get up many times before my digital clock ( five or ten minutes before ) . Interesting hub . Thank you.

      I feel we are both creatures of habit and have an internal alarm clock. Well maybe some of us do and other just sleep till they can... Great read!

      My husband certainly has an internal alarm clock and often rises to shut off the alarm prior to it going off. In fact it seldom alarms us to wake up. way! I would need that wake-up call. That...or I would not rest just knowing I had an early morning appointment.

      Very interesting. I attribute my "internal clock" to God Himself. I have often asked Him to wake me up at a certain time and He does! Love it!

      Last week I planned to be up and out by 9am. Woke up about 9. So - no, I definitely do not have an internal alarm clock. I'm also a night owl who has difficulty falling asleep. I know I have something missing which most others have, but try as I might I've never been able to change it.

      I really do believe that we all have an internal alarm clock , but maybe it is stronger in some than others.

      An enjoyable and thought provoking hub.

      Thank you so much for sharing.

      Take care.

      I have had an internal alarm clock for as long as I remember. My wife is a thankful recipient, and still constantly amazed, that even if I set the alarm clock she never hears it go off because I wake up about 5 minutes before the time and shut it off. I have always been able to go to sleep and wake up exactly when I want to without alarms - nothing I ever did to develop it, its just always been that way for me. I don't think about it or imagine it in my mind, I just go to sleep and wake up at the time I want to be up.

      Ok Bob, I'm takin' this! "fired up the coffee pot" :)I think it's precious that you committed yourself to helping her keep her committment. That's teamwork. I love it!

      Diamond, I too have done that on many occassions. I rarely use my alarm clock. I am going to keep checking back here to see what other have to say, because I too, wonder what is up with that. lol

      It may have been a coincidence, but I have heard so many instances of that sort of things happening. I can always tell what time it is during the day to about 20 minutes, or so. Maybe the moon or the sun's rays are in tune with our genes? You are a good husband, that's for sure! Bob
