Circadian Rhythms for every living thing

Science has proven the existence of certain biological rhythms that every living person, animal and plant moves to. The main rhythm that influences our daily lives is the Circadian rhythm. ‘Circa’ meaning ‘around’ and ‘diem’ meaning ‘day’. It is quite simply the circle of all life. Some call it Mother Nature.

Lasting roughly 24 hours, the Circadian rhythm is proven to be endogenously generated, that is it comes from ‘within’, although it can be affected by external influences such as light and dark, hot and cold. Put simply, it is a repetition of life in an orderly rhythmic manner. Day turns to night turns to day and then night again and so on. And everything beats faster or slower within the cycle. Our heart beats every moment, we sleep then wake up and then sleep again approximately once a day. All through nature circadian rhythm can be seen to effect when animals sleep, eat, reproduce and even plants regenerate. It is never ending.

In everyday life we generally take no notice of circadian forces other than we sleep when tired, eat when hungry etc. We see it in the seasons as summer turns to autumn and the leaves fall, then into winter and cooler temperatures, the rebirth of spring and then back into summer. It has always been this way.

Why does it exist?

Circadian rhythm is believed to exist with the purpose of protecting bodily cell replication from high ultraviolet radiation during the daytime and enables our cells to regenerate in the most efficient manner, time for rest, replenish stores etc thus keeping us alive and able to reproduce. It therefore governs our DNA.

There are many rhythms that our bodies naturally conform to. Our “biological clocks” so to speak. As humans we have gone to great lengths to “fool” this natural rhythm with the use of drugs, conditioning, environmental factors and the like. Science and medicine, even technology, all serve to keep us awake longer, sleep deeper, eat and drink beyond what our body asks, even stop us from aging. Our DNA is programmed with this rhythmic pattern of life. It just is. It is easy to ignore – it just happens – but as humans we do try to control it or bend it. For example, we try to squeeze more into our day by staying awake longer, sleeping less.

What if the rhythm was to change?

We only notice change when a rhythm is interrupted or stops. The simplest example of this is jet lag, when our normal rhythm of sleep is modified because of a change in time zone – night becomes day etc. This is an interruption to Circadian rhythm.

But circadian rhythm is more complicated than just that. Imagine you were subjected to a constant and unrelenting clicking sound. At first you would find it annoying and distracting, but in time you would become used to the noise and filter it out to the point where you would have to consciously listen to hear the clicking or you would not be able to hear it at all. But if the clicking noise were to suddenly stop – you would notice the silence and the absence of the click. Soon you would find the silence distracting and annoying but in time you would adjust to the new rhythm, that of having no clicking.

So what if the circadian rhythm changed – or stopped?

At first we would all be in a state of chaos, but gradually over time we would adjust to the new time keeping and go on with our lives, albeit in a markedly different way.

Any study of spirituality should include a deeper understanding of how our bodies, minds and souls exist in the natural world and why it is that we do the things we do. Sometimes there is a more divine force at work.
