Obstructive Sleep Apnea is a serious, life threatening disorder, which is generally not understood or taken seriously.
~ Originates from the Greek term - Apnea- absence of breathing.
-The prevalence of OSA was found through polysomnographic testing within clinical sleep laboratories. -OSA affects all age groups of both sexes.
People who experience OSA tend to have smaller upper airways. This characteristic has a huge effect on OSA. As the size of the airway reduces due to small jaw, tonsils, fatty tissue, or other anatomical factors, airway resistance increases. As the resistance is increased, patients must put forth a greater effort to maintain adequate air exchange. The greater effort through a smaller airway causes the relaxed muscles and throat tissues closed. The airway collapses and initiates an obstructive sleep episode. Luckily, many times the airways do not completely collapse and a person experiences a hypopnea. A hypopnea is when blood oxygen falls while efforts continue to increase. The apnea is then terminated by arousal.
The terminated airflow through the nose and mouth leads to numerous amounts of arousals throughout the night as well as an inability to achieve deeper states of sleep. These in turn leads to excessive daytime sleepiness, SNORING, dry mouth, headaches, restlessness, and awakenings due to choking or gasping. Many people do not diagnose themselves however, their bed partner does. Patients rarely complain about numerous arousals, however this effects how they live everyday and what risk they are in. The lack of sleep causes people with OSA to fall asleep throughout the day while reading or even driving a car. DROWSINESS IS RED ALERT!!!!!!!!!!!!!
If you suspect you have OSA there are ways to treat it, so do not panic. First, go see your physician or a sleep doctor. The first successful treatment was 1969's chronic tracheostomy. In recent years this ahs been replaced with:
-Continuous positive airway pressure(CPAP)-provides a "pressure splint" to the upper airway. Prevents inspiratory effort and causes throat to collapse.
Radio Frequency Reduction- A relatively new approach to treating OSA is using radio frequency to shrink the nasal turbinates, the uvula or the tongue.
-Uvulopalatopharynoplasty (UPPP)- used with moderate and severely ill patients. The uvula and portions of the posterior soft palate, anterior and posterior tonsillar pillars are cut out. A relatively new approach to treating OSA is using radio frequency to shrink the nasal turbinates, the uvula or the tongue.

Welcome! This site is continuously being created by students of Dr. William C. Dement's Sleep And Dreams course at Stanford University.
We made this site as a call to action for people all over the world to live healthier, happier, safer, and more productive lives by learning about their own sleep. We have faith that reading the information provided on this site will motivate you to be smart about your sleep deprivation and strategic about your alertness in order to live life to your fullest, most energetic potential.
In fact, we challenge you to do so! What do you say, are you up for the challenge?
Dr. Dement's pioneering textbook has been the core text for Sleep and Dreams since 1980, but it has just recently been made available to the wider public for the first time.
In it you'll find a more detailed account of the most important things you need to know about sleep, alertness, dreams, and sleep disorders. Studies, statistics, plus plenty of Dr. Dement's classic anecdotes painting the history of sleep medicine.
A revolution in personal sleep tracking, the Zeo is a wireless headband that transmits your brainwaves in realtime to a dock (pictured here) or your smartphone. The result? You can wake up and see exactly what stages of sleep you were in during the night! Unprecedented personalized sleep knowledge.
Ever woken up paralyzed? A surprising number of us have, believe it or not. But few know the actual causes of this phenomenon, and fewer still how to exert control over it. Dream researcher and sleep paralysis expert Ryan Hurd shares breakthrough insights into how to do just that.
In 2007 I discovered a guide to website building that would change my life. After learning from it diligently, it would eventually empower me to help Dr. Dement take his life's mission of spreading education about sleep health to the online world. Now, several years later, this site reaches over 100,000 visitors per month and counting.
The results are due in large part to the methods taught in that guide, and they are replicable for others who have knowledge of a subject they would like to share with the masses. I've detailed some of my journey here for those who might be interested.
