Hi, my buddy and me are the first time freediving in dahab in the sea. Now the problem is, after about 30 minutes she feels super sick and we have to leave the water. We have been on a lot of boat trips and she never experienced sea sickness nor did she felt any sickness during freediving in fresh waters. Any idea?
 
I tend to get a bit queasy myself if there are any swells going on... we dive in heavy currents with some swells here. I usually just heave and puke a little on the surface after half an hour or so and am fine after that for the rest of my dive. Makes for good chum if you're out spearing!
 
I get the same thing, after a while in the water my stomach feels abit sea sick, even if it is flat water.

I think its from the free diving up and down for a while.
It moves the liquid in your stomach around, you get acid reflux from the stomach going past the diaphragm as you turn upside down to dive down a lot and the acids in your stomach reach up in your esophagus.

Also swallowing salt water from your snorkel, even small amounts tend to make your stomach feel sick and the feeling of throwing up.

Thats usually the causes, but would be interesting to hear if any one had any remedies or preventions for this??????
 
try getting some raw ginger, shredding as thinly as possible, then place in very thin cloth squeeze and extract juices, add 50ml of the juice to about half a liter of water, add a small spoon of sugar if taste too bitter. also when in the water and the sickness begins try to occupy your thoughts as much as possible concentrate on the reef and your dive buddy, try to forget that you are feeling sick, kind of like will yourself better.
 
I sometimes barf while spearing, usually if it is particularly choppy or when there is a big swell. Exerting yourself, for example, swimming against the tide or against/across a rip current can contribute to it. As can getting salt water in your mouth and tiredness. Sometimes I just feel a little ill, other times I feel sick for a while before barfing, once I barfed with almost no warning at all - that was weird. Sometimes I recover quickly and carry on, other times I head straight for shore. These days I tend to head for shore - I guess that's what I would recommend in general. The problem is, you're never quite sure how bad it might become or how long it might last.

I have found a few things that help. Don't eat cereal - I think milk might be a problem before diving. Eat a simple, moderate fried breakfast: bacon & egg - perhaps best to forgo the tomato/beans/...not sure about fried bread as the fat seems to help, perhaps something to do with drawing blood to your intestines. Don't overeat or over-drink the morning of the dive, leave sometime after eating before diving. Hydrate the day before and don't get boozed up. Not sure about sugar (anybody else got any thoughts on that?).

Sea sickness medication might help. Some rate accu-pressure wrist bands for travel sickness. I've also heard that bouncing around on a trampoline can help get your mind and body prepared for it. Love trampolines, unfortunately I'm above the maximum weight rating for my son's garden trampoline :)

Interesting you say about the cereal or milk, as usually that is what i eat.
I find that heavy foods are a problem as well even after some time has passed before diving... i while still taste the food in my mouth as i feel sick.

The part about the fats are intriguing, i am going to try that.
I also find that being really well hydrated definitely helps.

I hear sugar and grease contributes to anxiety and motion sickness.
