Sleep Apnea and Napping


Janna Mantua - August 13, 2013 - Cutting-Edge Research
Have you taken a nap today? If not, have you wanted to? Napping is not “abnormal.” In fact, humans are probably supposed to nap in the afternoon when our circadian rhythm takes a dive. In most cultures, though, napping during the day is thought of as a sign of slacking or overall laziness. On the other hand, other cultures, such as the Spanish culture, do not frown on taking naps. But in these cultures, who needs the naps the most? If someone was ultra sleep deprived – let’s say because they suffer from sleep apnea – would they need to take naps more frequently?  A team has already taken on this question to explore the napping characteristics among a population in Caceres, Spain. Phone interviews were conducted to gather research subjects who were regular nappers and those who were not regular nappers. In this study, a napper was defined as... Read more

Sleep Apnea and Glaucoma


Janna Mantua - August 13, 2013 - Consequences of Sleep Apnea
Glaucoma is a group of conditions that causes damage to the optic nerve, the main nerve that connects the eye with the brain. Damage can lead to an irreversible loss of vision. Although there are a few causes for glaucoma, the main one is an increased amount of pressure in the eye. Risk factors include increased age, ethnic background, and medical conditions like hypertension and heart disease1. Because we know each of these factors is independently linked with sleep apnea, the question to follow is how many of those suffering from glaucoma also have sleep apnea?  A group of scientists recently took on the mission to study the relationship between these two disorders. This group examined a large group of people (114 subjects) who underwent overnight sleep studies after their doctors suspected that they may be suffering from sleep apnea. In addition to an overnight sleep study, the subjects were... Read more
