Do you find yourself feeling tired in the middle of the day... every day? We all love our naps, but they should not be necessary on such a frequent basis. If you find that you are fatigued daily to the extent that you require some shut eye, it could be a sign that you are suffering from respiratory issues.

The data surrounding this is shocking, and a little bit scary if you're an avid napper. A study showed that those who take a nap every day, but for under an hour each day, are 40% more likely to die from a respiratory disease. Those who took a nap every day for over an hour had over twice the likelihood of dying from a respiratory disease than those who do not take frequent naps.

So, if you find yourself relying on those siestas, you might want to visit your doctor.
