Taking an afternoon nap may be   causing more harm than benefits, a recent study revealed.  
Researchers at Cambridge University   conducted a 13-year longitudinal study involving 16,000 British men and   women. The study was conducted in the late 1990s, during which the volunteers   gave information about their sleeping habits. 
After 13 years, the researchers were   able to record 3,000 deaths out of all the volunteers. The major causes of   these deaths were respiratory diseases. Experts explained that dozing off frequently in the   afternoon could either imply or   result in underlying health risks   such as bronchitis, emphysema, pneumonia, and other lung diseases.  
People who nap for more than an hour   daily also have a higher risk of dying due to respiratory diseases than those   who doze off for less than an hour. Results also showed that taking a nap for   one hour or more increases the risk of premature   death by 32%. But if the nap lasted for less than an hour, the risk of death   goes down to 14%. Researchers believe that this finding may be because   napping prompts inflammation in   the body. 
One study conducted in China backed   up this study, stating that post-lunch snooze for more than 30 minutes have   higher risks of Type 2 Diabetes. However, scientists are still not sure   whether it’s the disease that makes people want to take a nap.  
In addition, the results of the study   do not imply that taking a nap is always harmful. A professor at Loughborough   [luf BUHR-oh]   University said that taking short naps or “power naps” may still be   beneficial, as it can make people feel recharged and more productive.
