Why labour hurts 4

Imagine you are still a cave woman who is just so fed up with life in a damp mouldy old cave. So along with your hunky cave man you decide to go live on the hill. You look forward to waking up to a stunning view bathed in untainted primordial sunlight. Bliss.
However, there is one factor you forgot to consider. A hill. You will have to carry all your building materials up the hill to build your hut. Gravity will not be your friend. However, if you decide to build in the valley and forgo the stunning view, it will be easier to get materials down rather than up.
So working WITH gravity is easier, mmmmm.
If we lie down in labour the hard working uterus has to work even harder cos it is working against gravity, pushing baby up hill. The contractions will have to become stronger and so become painful.
If we remain in an upright position, on a chair/birthing ball or leaning forward on a bean bag etc. then the contractions are working with gravity and do not have to increase in strength. Simple.
Then why oh why do women, as soon as you show them into the labour room, make straight for the bed and lie down. We have chairs. We have birthing balls. We even have a large scrunchy bean bag. We also have a beautiful birthing pool where you can sit or kneel in relaxing warm water and labour in comfort.
Once you are aware of why labour hurts you can face labour with fresh expectations. You can make a birth plan that includes staying upright and use of the pool to relax in. You can inform your midwife and birthing partners that you need a quiet atmosphere in order to do your chosen relaxation technique.
You can have a pain free labour.
You can do it.
I did it.
Twice, so I know it works.
