Are you a B-person? February 18, 2008

Yes! Yes! Yes! – great news indeed for someone like me: it is scientifically proved that some people need to start working later. Denmark’s B-Society was found in order to advocates the rights of ” B-people” who are sluggish and bed-bound first thing, but whose energy spikes in the evening.

Every individual has their own biological rhythm (known as the “Circadian rhythm”), which means we have our very own sense of time and planning of time. There are lots of different kinds of circadian rhythms. Most people are B-persons,which means that their circadian rhythm has a cycle that runs through 25 hours or more. Science has shown that our biological rhythms through “a day” (i.e. “Nychthemeron” = “a day and a night) are regulated by a so-called “clock gene”.
B-persons have a clock gene lasting 25-27 hours, whereas A-persons have one that runs for approximately 23 hours.

Dr Roberto Refinetti,a biopsychologist at the University of South Carolina, is an expert on circadian rhythms. “These rhythms describe anything in the body that shows a daily oscillation,” he says. “Your temperature rises and falls at the same time every day and you probably feel drowsy at around the same time daily. But circadian rhythms also control your blood pressure, glucose levels and much more.”

So why do they vary from person to person? “Just as some people are taller and some are better-looking, some people’s internal body clock synchronises with the outside world in a different way. And this can affect your performance. For example, in an Olympic competition, your circadian rhythm could make the difference between gold and silver, depending on the time of the race,” he explains.

I always knew that!  – I mean I was suspecting something like that 🙂

What I really love about this idea is that

B-Society B-certifies companies and public institutions, who accept and respect B-people’s work rhythms. When B-people’s work rhythms are considered at the work place, their productivity and quality of life is increased, which increases productivity for the entire organisation.

Luckily in my present job I can be more flexible. The thought to start working at 8 am or even at 9 pm makes me sick! However, when I by chance get out of the house earlier in the morning, there is such a wonderful peace and freshness, such a special beauty and some kind of a meditative mood… – and then I think “WHY??” Why can`t I do it more often? But the science proves that I can`t.

LOVE, axinia

    I have a clock gene lasting 20-22 hours…
    Am I C-person/

    C-Person sounds good…
    Do you mean you have to sleep lees or more?

  3. Sigrid Says:

    I am definitley a B person then!

    I would say I need to sleep less but more often 🙂

  5. Yes, it is for real.
    A-people = larks = “morningness” chronotypes.
    B-people = owls = “eveningness” chronotypes.
    Those people are all normal. But NB!, they vary in their degree of flexibility, as in how easily they can go to sleep and wake up at the “wrong” times according to their internal daily biological rhythms.

    There are also disorders of circadian rhythms which fall outside of the normal. The shorter term situational ones are jet lag and night or rotating shift work. The life-long ones include DSPS, Delayed Sleep-Phase Disorder(Syndrome), which I have. It’s like being an extreme, inflexible B-person. So I wish the B-society luck with their projects, as they will also benefit people like me.

    I appreciate seeing people blog about circadian rhythms. More wide-spread understanding of them can only help.

  6. […] B-person, I find it hard to wake up in the morning. I mean to fully wake up, not simply hang around like a […]

    Thank god for science. 🙂 Finally Science explains that it is not that we are lazy and hence dont get up early, its that we are designed that way by nature 🙂
