Baby hammock safety study shows safe oxygen levels


We have been making the Nature's Sway baby hammock since 1993, and in those 25+ years, we’ve had countless satisfied customers. Now, we also have some scientific research showing that when used correctly, the Nature’s Sway baby hammock does not compromise a baby's breathing or oxygen supply.

The Medical School study originally hypothesised that the gentle curves of the hammock – both lengthways and sideways – could result in reduced oxygen levels for the baby.

But that wasn’t the case.

“Contrary to our hypothesis that sleeping in the hammock might lead to flexion of the head on to the chest, we found that the prominent occipital protuberance of the infants’ heads was accommodated in the type of hammock that we studied. The hammock contained a relatively soft wool-fibre mattress supported by the fabric of the hammock and the relative weight of the infant head compared with their body resulted in curvature of the infant body but relative preservation of neck extension (Fig. 2). Consistent with this observation, there were no differences in obstructive apnoea or oxygenation in infants who slept in the hammock compared with the bassinet, suggesting that the hammock did not compromise the upper airway.”

In the future, we hope that more research can be done to address any other safety concerns or demonstrate some more of the potential benefits of the hammock.

The results of this research should bring peace of mind to parents and child care
practitioners who want the science to support their use and recommendation of the
Nature’s Sway baby hammock.
