Anthropologist James Mackenna two studies published in 1997 in Pediatrics. Their work was based on the control of brain waves, eye movements and breathing rates of mothers and children. Also used infrared cameras to take constant importance of both movements during sleep. Their findings were very important and allowed him to argue that co-sleeping protects against sudden death.
Babies have different sleep patterns than adults. Spend more time in light sleep (REM), which is much more responsive to the changing environment. When they reach the deep sleep stages get to have episodes of apnea in an average of 15 seconds, which easily out returning to the waking and REM sleep. Awakenings why babies are normal and healthy. Need to stay alert in the dream as a survival mechanism. The study recorded very well that when mother and son bed sharing their breathing, heartbeat and movements rirmo synchronized. The mother is more alert and their sounds, touch and movement are a beneficial influence on the young. baby sleep together and synchronized, breathing movements and affect each other. REM sleep stages of both increase and the baby is very sensitive to the presence of the mother, while the possibility of awakening in times of apnea co-sleeping thermoregulation not only improves the stability of breathing and heart rate, but is a very beneficial factor in maintaining breastfeeding and its duration, which has long since known to exert a protective effect by itself, on sudden death. To facilitate co-sleeping and breastfeeding is a factor for the prevention of sudden death, in addition to the timing of sleep cycles. The study concludes with a call to the health authorities to make efforts to promote breastfeeding in the minimum term recommended by the WHO and also the co-sleeping safe. Other works by this author have an impact on the importance for brain development and emotional co-sleeping, as well as the differences in data sudden draw, across cultures related to the survival or normal mode in which children have always s
