Your body clock is plotting against you

Our "body clock" regulates sleep and wake cycles, body temperature and blood pressure.

Most drivers are not aware that an internal mechanism is secretly plotting to create problems. The problem is our circadian rhythm, a pattern of activity that occurs on a 24-hour cycle within virtually every living creature. This “body clock” regulates sleep and wake cycles, body temperature, blood pressure, in addition to the release of various hormones. Each day we experience profound changes in both mental and physical condition as our body, and brain alternate between periods of rest and activity.

Think of your circadian rhythm as a pattern of peaks and valleys. At maximum amplitude we are most alert and at the peak of our functionality. At the other extreme, we are least alert and can hardly function. During these lows we can easily become drowsy or fall asleep. For most of us, the low points occur somewhere between two and four am, and 2-4 p.m. The latter is the problem. If you are behind the wheel at that time, there is a strong possibility, baring any outside influence, you can nod off, or that your concentration will lapse dangerously.

At the age of five I was already obsessed with all things automotive being able to identify the make and model of car by just the sound of its engine going down the street in front of our house in the small town on the south shore of Nova Scotia. Although I have been covering and writing about the automotive scene for more than 40 years and the light still grows brightly.
