Health tip: Adjusting the rearview mirror

Special to the Bonanza

Do you adjust the rearview mirror in your car? Most people do. Twice a day, as a matter of fact — once in the morning and again in the afternoon. Does your height change throughout the day? Yes — you shrink during the day and lengthen during sleep.

How is this? All of the height changes happen within your spine — to be more precise the discs of the spine. The spinal discs bind water, which gives them the necessary shock-absorbing properties.

Because we are weight bearing throughout the day, the effects of gravity slowly squeeze the water out of the spinal discs. This process thins the discs, making our spine shorter at the end of the day.

The process is reversed at night. At night as we lie in bed our bodies are non-weight bearing. This extended period of non-weight bearing allows the discs to re-hydrate.

The re-hydration of the discs creates healthier, plumper and more shock-absorbing discs. So, we are taller in the morning and shorter at the end of the day, which is why we adjust the rearview mirror in our vehicles.
