Marta, by site when diving there is no problem, that the diving vest has pockets everywhere.
What I carry are a couple of emptyness of a hyperglycoso gel that cyclists usually use.The container is plastic type so it does not spoil when wetting.During an immersion I can't "get" take something quickly.You have to take it under water.(Yes, you can, it is not very complicated).
My wife has two others in her team, and the glucagon awaits us on the shore or on the boat, depending from wherever the immersion is.
To snorkel, it is not difficult to find some skter bags that you can wear hanging from the neck, or subject to the waist.Look at any sports or diving material store.I use one to take the car keys during snorkeling, and they are safe, so you can take to a sugar without fear of spoiling.
Snorkel consumes, maybe not as much as diving, but you will wear.I would follow the same recommendations as for diving.
Basically: to do more than two hours that you have injected insulin, measure 1 hour, half an hour and just before starting.Try to enter the water with 150 or higher blood glucose.And eat some slow hydrate, a ration for every half hour that you anticipate being in the water.
And be careful with the cold, which wears faster.
He continues with the snorkeling, and then makes the leap to the bubbles.By law we have prohibited it, but we are many who do not give up that pleasure, yes, with all security measures.
Greetings.
