The prone or
side sleep position can increase the risk
of rebreathing expired gases, resulting in hypercapnia and hypoxia.54, — , 57 The prone position also increases the risk
of overheating by decreasing the rate
of heat loss and increasing
body temperature compared with infants sleeping supine.58, 59 Recent evidence suggests that prone sleeping alters the autonomic control
of the infant cardiovascular system during sleep, particularly at 2 to 3 months
of age, 60 and can result in decreased cerebral oxygenation.61 The prone position places infants at high risk
of SIDS (odds ratio [OR]: 2.3 — 13.1).62, — , 66 However, recent studies have demonstrated that the SIDS risks associated with
side and prone position are
similar in magnitude (OR: 2.0 and 2.6, respectively) 63 and that the population - attributable risk reported for
side sleep position is higher than that for prone position.65, 67 Furthermore, the risk
of SIDS is exceptionally high for infants who are placed
on their
side and found
on their stomach (OR: 8.7).63 The
side sleep position is inherently unstable, and the probability
of an infant rolling to the prone position from the
side sleep position is significantly greater than rolling prone from the back.65, 68 Infants who are unaccustomed to the prone position and are placed prone for sleep are also at greater risk than those usually placed prone (adjusted OR: 8.7 — 45.4).63, 69,70 Therefore, it is critically important that every caregiver use the supine sleep position for every sleep period.
On the flip
side, I have gotten a lot
of emails and letters from people who follow a low - carb diet or specifically paleo diet who are working out 5 - 6 days a week and dealing with horrible sugar cravings, hormone imbalance and other issues
similar to what I experienced, and I can only attribute this to our
body's preference for using the glucose from carbohydrates as its primary energy source.
Although hormonal imbalances are a common cause
of non-itchy, symmetrical (same
on both
sides of the
body) hair loss in dogs, they are an uncommon cause in cats that have hair loss that look quite
similar.
