The words ‘biological clock’ may conjure up images of dancing babies, but there’s much more to the biological clock than that last minute urge to make babies that supposedly kicks in at a certain point in a woman’s life.

For a start, both men and women have a biological clock, as being celebrated by Biological Clock Day, and it affects their behaviour and mood on a daily basis. It maintains a sleep-wake pattern that fits in with the light and dark of a day on Earth. More formally known as the circadian rhythm, it monitors light, temperature and other environmental factors to influence things like alertness, energy levels, hunger and motivation.

The technology of today’s world can upset the balance of the biological clock, so celebrate Biological Clock Day by setting aside some time to re-regulate it; create a regular bedtime routine, minimise naps and eat regularly.
