Brasil’s been taking a lot of flack about the sub-standard housing the Olympic athletes have been given. Will sleep (or the lack of sleep) be the difference in where they all medal? -D

The Huffington Post’s Stuart F. Quan, M.D. reports that recent information indicate that athletes sleep less well than non-athletes, and that an increased rate of obstructive sleep apnea is observed in athletes with a high BMI and increased neck size. Furthermore, travel across time zones with resultant jet lag may also lead to problems with getting adequate sleep. Are these deficiencies in sleep important in affecting athletic performance?
