Going to altitude after diving may be a problem because at altitude atmospheric pressure drops in a similar way to when you fly. There are flying after diving guidelines to follow, which should also be followed when driving to altitude after diving. Depending on the organisation flying after diving guidelines you wish to follow. Plus depending on how many dives you’ve done and whether these involved decompression stops, the recommended surface interval can be anywhere between 12 hours to 24 hours before you drive to altitude after diving.
Whether you can you dive and fly on the same day boils down to the risk you are willing to take. It depends on which flying after diving guidelines you want to follow. Plus it depends on how many dives and the type of diving you’ve done. Your decision should also be based on decompression risk factors and how many of these affect you specifically. Certain organisations provide flying after diving guidelines that look at the maximum altitude you will be flying at and whether your dives involved decompression stops. DAN and PADI’s flying after diving guidelines begin with a surface interval of 12 hours to a maximum of 18 hours before you fly after diving. Whereas BSAC and the U.S. Air Force recommend a 24 hour pre-flight interval after surfacing from your last dive before flying.
Whilst the cause of scuba dry mouth is down to breathing dry compressed air through your mouth, it can be prevented. Examples of how to prevent a dry mouth when scuba diving includes: Keeping well hydrated by drinking plenty of water; avoid drinking excessive amounts of caffeine and alcohol; Being aware of the diuretic effect of any medication you’re taking; swilling some water in your mouth when diving; or diving with a full face dive mask so you can breath through your nose. instead of your mouth.
The fact that some of the best dives in the Maldives have strong currents where conditions can be challenging. Also some of the good dives can be deep dives and many involve diving with potentially dangerous underwater creatures. But also some dives involve diving at night on liveaboards. Despite all this these things, so long as you have the appropriate training and experience for the type of dives you intend to do in the Maldives, plus so long as you follow safe diving practices it’s totally safe to dive in the Maldives.
The scuba diving equipment you need for Antarctica includes the following: Drysuit and hood; Thick drysuit under garment; Dry gloves or thick wet-gloves; 2 separate freeze protected regulators; Pressure gauge; Buoyancy control device; Depth gauge, dive watch or dive computer; A compass; Diver’s knife; Dive torch; Mask, fins and snorkel; Plus your own weight belt but not the weights.
Scuba diving Antarctica is about the pristine clear waters and about enjoying one of the richest bio-diverse ecosystems on the planet. But whilst the answer is yes you can scuba dive Antarctica, it’s not for beginners. To dive Antarctica you will need prior experience of cold-water diving and of diving using a dry suit. Plus I recommend a minimum of 30 dives including those in cold water.
