World Sleep Day


Chrys Horn

I wonder how many people know about World Sleep Day.  It is celebrated on the third Friday of March each year (this year it is on the 20th) and it’s a good time to ponder the importance of sleep.  

We all know about it when our kids don’t get enough sleep, but good sleep is also really important for adults. 

Sleep researchers have found that good sleep protects us from obesity, diabetes, colds, heart disease, strokes and depression.  It also increases our concentration and productivity, and our athletic performance. 

As an example, studies have shown that sleep is surprisingly strongly related to obesity.  A lack of sleep increases the levels of ghrelin a hormone that causes hunger and decreases the level of leptin, a hormone that suppresses appetite.  As such, people who don’t sleep enough eat more.

A good night’s sleep increases immunity to the common cold.  In an experiment where people were given nasal drops containing cold viruses, researchers found that people who slept less than seven hours were almost three times more likely to develop a cold than those who slept eight hours or more.  

If you are not getting a good night’s sleep, then it is worth experimenting with ways to increase it.
