Tadasana also helps with tiredness, as tiredness often causes a sagging posture, which restricts the breathing, already restricted by the growing baby. Standing postures, such as Trikonasana, the triangle pose, help with fluid retention in the feet and ankles, as well as all the other benefits associated with this posture. Care must be taken, particularly towards the end of pregnancy, not to over-stretch the muscles. The muscles and joints are more 'stretchy' than normal during pregnancy, due to the release of the hormone relaxin, which is released into the bloodstream in preparation for the birth. If any posture becomes uncomfortable or does not feel appropriate it should be left out - there is so much else that still can be done.
Relaxation is a learnt skill which improves with practice.
The relaxation response opposes the effects of stress which has benefits for both Mum and baby. If lying on the back is uncomfortable, try the 'recovery position' as shown below. Meditation and breathing exercises help to get in touch with those birthing instincts that reside within every woman. Bringing a new life into the world is a great life-changing experience. Taking some time to reflect and meditate helps to increase confidence and inner strength, in preparation for the great event to come.
