Many of us developed a love for afternoon naps while in school because it was mandatory to “sleep” after lunch. It may have been a luxury to get restful sleep in one’s junior years but our brains got the message: sleep after lunch to get a boost in energy to prepare you for the rest of the day. As the years rolled by sleeping after lunch for instance has become a mirage but everyone loves a “power nap”. The French do a great job when it comes to their afternoon break.
If you enjoy your naps, you may have experienced that feeling of extending your sleep once you go beyond half an hour. It’s that feeling of no turning back. On the other hand if you nap for just about 30 minutes you seem to have a new lease of energy. I love naps whenever I get a chance to squeeze one in, but school had siestas that lasted about an hour so sometimes I love to revisit the days of old. A new research finding is however about to trample on that glorious time spent hitting on the snooze button and being at peace with the sheets, chair or even bench or floor in some instances.
We all appreciate that getting enough sleep is key to good health but this study suggests that long daytime naps may not be in your best interest.
The researchers found that long naps in excess of 40 minutes and excessive daytime sleepiness were associated with an increased risk for conditions such as high blood pressure, diabetes, obesity and high cholesterol; collectively referred to as metabolic syndrome.
The research showed that people who napped for less than 40 minutes were not at increased risk for metabolic syndrome. In fact, those who napped less than 30 minutes had a slight decrease in risk.
The findings seem to point accusing fingers at those of us who nap for over 40 minutes; that is when the problems seem to begin. I am sure you can confidently guess what happens when people nap for over 90 minutes; the risk of developing metabolic syndrome increased by as much as 50%.
“The review also found that napping for more than an hour or being overly tired during the day were both linked with a 50 percent higher risk for type 2 diabetes.”
“However, the study only found an association between these factors, and did not prove that excessive sleepiness and long naps actually cause metabolic syndrome or diabetes.”
Is it possible that those of us who nap for long periods of time also avoid physical activity and probably over-indulge in comfort foods hence increasing the risk for these life-style diseases?
One thing is certain, you cannot go wrong with a short nap; it can be extremely satisfying. So while the scientists continue to explain and maybe confirm these findings, let us limit our naps to 30 minutes. If you have extra time take a walk or get some work done.
This may be a reminder that too much of even a good thing may be harmful. Sleeping has great benefits including reducing our risks for developing heart and blood vessel diseases such as stroke, it improves our immunity and also enhances our performance in all spheres of life. Just as sleeping in excess of 9 hours at a time has been linked with bad outcomes, excessive daytime napping is now getting its “day in court”. Moderation in all things must be key!!
A 20 minute nap in the early afternoon may:
How long did you nap today?
AS ALWAYS LAUGH OFTEN, ENSURE HYGIENE, WALK AND PRAY EVERYDAY AND REMEMBER IT’S A PRICELESS GIFT TO KNOW YOUR NUMBERS (blood sugar, blood pressure, blood cholesterol, BMI)

Thought for the week – "Sleep is an important component of our healthy lifestyle, as well as diet and exercise," says Dr. Tomohide Yamada. "Short naps might have a beneficial effect on our health, but we don't yet know the strength of that effect or the mechanism by which it works."
