[Hammock Camping] Re: Feet Higher Than Head?
- Jackie, that is very useful. Thanks for sharing it with us. It is
cetainly something that I am glad to be aware of so that I can
quickly recognise the condition and try to remedy it quickly if it
ever happens. Sounds a little like one thing leads to another, leads
to another, but elevated feet can be a major contributer to the
domino effect and it is necessary to immediately remove the pressure
on your cranium by quit elevating the feet if something doesn't feel
right in your head. I have experienced domino effect problems that
get out of hand when I have scuba dived in the past and the immediate
remedy is of course, to get to the surface to relief the symtoms
associated with the increased pressure.

wind can cause them to pull them out. I would think that tying off
to roots, branches, etc would be in order if possible as well as
placing logs or rocks on the line where the stake enters the ground.

What Jackie did not mention is that vascular headaches don't happen to
everyone. If a hiker has a history of vascular headaches, then watching
out for putting the feet too high is a great idea. If the camper has
not had them (migranes, etc.) then it is unlikely that sleeping with the
feet slightly elevated will give a hammock camper their first vascular
