Coming up without stops?

[stanw]

I am obviously new to all of this so thanks for your patience. Why is it ok to free dive and come up without worrying about decompression sickness?

Thanks.

well, the freediver D0ES HAVE to worry about DCS, just for the most part, it won't affect a recreational freediver. Breath-hold Diving:Taravana

for the most part you probably wont ever have to worry about DCS while freediving. Mostly it occurs in people who are freediving commercially for lobster, pearls, etc. and make multiple deep dives a day. If you want to be really conservative or are freediving around the same time as a SCUBA dive...just treat your freedive as an actual SCUBA dive and use your charts. If the time and depth you are diving fall safetly within the charts. Then there is very little youd have to worry about as far as DCS goes.

Overall youd really have to be pushin the limits to worry about that too much but it is possible.

Have fun/safe dives!

I am assuming you are talking about breath hold diving. The biggest reason is where the breath comes from.

The free-diver takes a breath at the surface where the percentages and partial pressure are normal. During the dive no added nitrogen is introduced into the tissues.

A scuba diver, adds nitrogen at increase partial pressures with each breath.

If you are talking about no-decompression recreational diving and the no stop abilities if they are within the allowed time limits it is semi-complicated. The short answer is your tissues can handle a certain amount of excess gas without rupturing. Limit the amount of additional saturation and you are OK.
