Have you ever wondered why you feel drowsy during certain times of the day, even though you may have gotten good sleep at night? That’s quite normal. Why? Because of circadian rhythms – in other words, your body clock.

Just as our body clocks are programmed to be more alert during certain periods of the day, they are also programmed to have 2 drowsy periods. So, even though you may be sleeping well during the very early hours of the morning, you are still programmed to feel drowsy again in the mid-afternoon. It’s a natural function of your circadian rhythms.

So, what happens to your circadian rhythms if your work schedule requires you to be awake during the night – or if you have to work for extended periods of time?

If your natural circadian rhythms are disrupted in this way, you can expect to see a negative impact on the quality and duration of your sleep, and your task performance. This can also create a sense of personal imbalance in your life.
