when you stay more than an hour at 6-4m than it becomes very tempting... unfortunately original packaging does not work well (can / glass bottle) than you loose gas and worm it up that spoils the fun
My folks told me about how they used to drink a beer underwater by turning a bottle up and blowing into it- essentially shotgunning a beer. A good beer is a standard after a day of diving.
Take the "don't exert" bit seriously, folks! I had a mild-ish case of bends (after nothing wrong with my dive profile) needing 2 sessions in the chamber, after big exertions unloading the weekend's kit at the harbour after the last dive (a bit of a workout, loads of stuff and it was now low tide with the quayside 6ft above the boat deck). And 2 people in my club have had more serious effects from comparable over-exertions.
@@scubababy3410 its to do with DCS If I remember right one part is the energy using to fin can be classed as intense workout and the rapid descent and ascent can cause bubbles
@@scubababy3410 Normally, rapid ascents aren't an issue for breath-hold divers, because they never breath compressed air. But if you breath-hold dive after having scuba dived, some of the off-gassing of gas taken in during the scuba portion can go into the bloodstream during the deep portion of the breath-hold dive as small bubbles, which would then expand too quickly on ascent and be a possible source of an arterial gas embolism. If you want to snorkel after a scuba dive, do it only on the surface; it is, after all, supposed to be a post-dive *surface* interval.
Good recovery on saying that “you’re still okay to carry your tank”. Clearly years of teaching has helped you answer that question before being asked. 😂
So you came here to check for a quick summary? Here it is: 1. No hot baths or hot drinks - warm up slowly & naturally 2. Dont fly (duh!) 3. No alko, limit coffee 4. No gym, no physical stress 5. No massage - avoid increased blood flow
Coffee(and tea) aren't really problems. While they're diuretics, the liquids still hydrate you more than they dehydrate you, just be careful about using them to warm up.
When I worked a dive boat in Cairns literally all the boats would come in and hit the pier bar happy hour every night, it was one of the best end of work rituals ever! Never heard of anyone having issues other than hangovers!
One of our DMTs got hammered the night before a dive in Utila some years ago. Looking back, I'd say she might have still been a little pissed. After two dives, the first to 120 feet at the Haliburton wreck, she started complaining about discomfort in her right elbow... Off to the chamber!
I'm curious, people who works with diving, when do they get to work out? Because staying fit is also important and might make you less likely to get DCI. If I work 6 days a week with diving, when would it be safe for me to exercise, like go runing or go to the gym? Only once a week?
Hi Katrin, when I was working full time with diving, we usually finished the last dive of the day around four p.m. If the dives are only rec, you are fine to go to the gym in the evening, just check your tables and if you are outside the surface intervall table you should be fine 🙂
Also, diving, prepping, cleaning and carrying student gear all day...might be a reason the pro's don't go to the gym. Most of them light a smoke after the dives (face palm)
I know some smoking divers, some even light one on the boat. For the beer, I'm guilty of it sometimes, but only once on the shore with dive buddies. I'm the young dude amidst a 40+ years old dive group x)
I would have thought that "don't hide issues or injuries" would be on the list. I was on a dive 80' max with other divers at a reef. Nothing difficult in the dive profile. Required 750psi back on the boat. As all divers consume air at different rates, some were out earlier than others. The last diver out had a very long bottom time. Good for him on breathing technique. However on the boat ride back to the dock, he was connected to an EAN 36 tank with his reg and breathing off it. Trying to be discrete. Turns out he was holding his breath under water to conserve gas and came up with a headache. That could have turned into something much more serious. But he was trying to hide it. Not advising the crew was a mistake, though it turned out fine in the end.
Take a massage? The jury is still out there. As a dive instructor, I get asked that question often enough because massages in the Philippines are cheap. Massages relaxes a person and therefore the outgassing is more efficient. That thing about the dissolved gases not out gassing is a myth. A fellow dive instructor who is also a practicing doctor specializing in diving medicine says it’s ok to have a massage. Some other dive pro take the contrary view on this. I respect that but there is no concrete scientific evidence that massages may lead to less out gassing and that massages may heighten the risk of DCS.
Once again, as a new diver I'm thankful for things like this. Most of these didn't have a big emphisis from the instructors. I'm glad your channel exists. 😂💪
This is one of the few times my anxiety could work to my advantage since I’d be too paranoid to get decompression sickness and probably end up being extra cautious lol (which is a good thing)
Love the drinking part, when I worked in the industry we drank so much every night after work. Although most dives less than 40 feet an no one got hurt. Nothing like having a hangover and dry heaving thru the regulator. Thought for 8000 ft(cabin pressure) min time was 21 hours after last dive if in Z group. Guessing modern computers calculate it
I hope lots of people will watch this video over and over again. In our experience: The beer factor between dive is very common. Sun decking is the best thing to do after each dive, for the best experience never use suncream. (sarcasm!!!) Thank you, Mark, for uploading and taking your time with this topic.
I did my Open Water dives on a boat with a hot tub...SOP was to take a pail of water from the tub and pour it down your wetsuit between dives, and definitely jump in (sans wetsuit) after the last dive of the day. Maybe the tables are so conservative that it usually isn't an issue, but as far as I know nobody ever got even skin bends on that boat.
@@janainarudberg pretty darn cold. We usually wore a 7mm farmer john with a 7mm step through jacket over the top. Generally with a hood and gloves as well. We did have some drysuit divers out there as well but mostly we were okay in wetsuits. You'd think California would be warmer....
Yeah I never knew about hot showers after diving until working in Bermuda. Back in Scotland it was always find a hot shower asap to warm back up lol. Now when we get back to dock we tell everyone no hot showers after diving.
Been certified almost 40 years and never once have I been told not to take a warm shower after a dive. Decompression issues are related to time spent at depth, staying within the no decompression limits.
JAGCHiker None of my instructors (5) ever told me there would be any issues after a dive taking a hot shower. Being in the warm water for 5-10 minutes won’t make much of a deal. I will bring this up the next time I see him. 👍
@@Ndiver81 It's been standard curriculum for at least 15-20 years, probably longer, to warn people of post-dive hot showers. Hot showers will heat up tissues, increase circulation, and change off-gassing rates.
Yep, hundreds of dives, loads of people with hundreds if not thousands for some and all have a beer or ten and no effects. That's enough to debunk that one for me, and I'm a scientist.
Speaking of stupid dive mistakes. Once after diving in the morning in Hawaii we decided to take a drive up to the top of Mauna Kea (13,803′). Dumb! Fortunately no one had any issues. An associated point for parents, children under the age of ~16 may have problems with adjusting quickly to high altitudes.
Never thought about the temperature.decades of cold diving but never knew that.... My first dive in Spain I was clueless I put was decades ago but I went up a mountain after...it was before my paddy course though. Yes had drinks & dived but not much...but yeah bad idea. I do overdo it occasionally swimming about I don’t get out of breath I know not to but I’ll try not to swim too much...never knew that... Massages huh...never heard that.....ok all good stuff but I guess I never pushed the times & I usually dive nos 32 but on an air profile (not deep stuff) I do that cos my buddies dive air.. Really good info....I’m paddy so I guess I’m less informed than besac or what ever it’s called but A diver is what they make themselves...Can’t believe I never knew this stuff though
Do you know the feeling, seating on a bronk, the shoot door opens, horse takes that first step into aurina, an you get that rush of power as he make that upward power thrust, throwing you towards the sky!? Well, maybe you don't know that adrenalin rush! I had that same force against me, but from Lin cod bucking me feet into shallower water rather than a horse into the air! He power an size was more than impressive! You can be overwhelmed, but if you dive you must Except the Responsibilities of learning/training/practice/dedication/furthering sport to next generations/personal safety/safety of others! Tim
DAN’s recommendation for flying after diving is for cabin pressures above 2,300’. There’s no problem driving over a small mountain of 2,000’. Divers do this all the time in California. Inter island flights below 2,000’ are also not a problem. On the Big Island of Hawaii helicopters can airlift divers to the hospital without worries even though the hospital is well above sea level.
Travel Adventure, what are you basing the 2 hr recommendation on? DAN’s recommendation is specifically for altitudes of 2,000 - 8,000’. In 2002 they reported no known problems below 2,300’ and felt that 2,000’ was a safe minimum for flying after diving guidelines.
@@edmcneill7534 I'm talking about 1000m or so. I was on an island and thats what the divers told me after diving. Have lunch and then go to explore the island. One of the days after driving I was instantly super exhausted and feeling not good and had to go back to the hotel directly to sleep.
Been with divers and diving for almost 30 years and everybody hits the bar each night. Never seen any issues, even after decompression diving. Same for warming up in a hot shower after. Hundreds of dives, no drama. Flying, 24 hours is fine.
I know the manuals say stay away from alcohol but from my understanding , alcohol esp. beer dehydrating the body is a myth, when you drink beer, it contains a lot of electrolytes and you get way more water than any negative effect from the alcohol. However, I think it’s more important to be aware of moderate amounts, chances are you are going diving the next day again and you do not want to be hungover and not well rested before diving
What the!? I'm sure the millions of recreational holiday divers that do all these and probably even combine some of them (beer and a massage anybody??) And have lived to tell the tale are pretty good stats to debunk a lot of these. That is, if they are doing recreational dives.. Decompression diving is a completely different kettle of fish.
When we dove on San Juan, while leaving all dive table calculations to youngest rookie on board, we drank as much beer as time allowed before next dives! We starting shallowest beach dives first, then working deeper dives as day go on! We would always dive by ourselves so if one died it was only one! We loved skipping out of town on last minute with a surprise to everyone we were gone! Our smoke filled sky around air compressor always made us feel at home breathing smoke fill tanks an 225'! If we left anyone at dive sites it was understood we'd see them back on docks! We invite divers an divers would leave sites on their own so we never know who or how many were diving with us? We'd party throughout day an night with no sleep, want to get in Ten- 200+ft dives an fly out tomorrow, packing 200 lbs of dive gear! Does any of these personal adventures sound like your past history thrown in there in parts? Haha! Tim p.s. Boys, I know of cone mountain then start a circular drift around deeper an deeper that only a few divers know this whole mountain exist! I know a rock vertical wall, with a huge chunk missing to create a room with ceiling, two walls, but no floor looking into space where at any moment an orca killer whale or 100+lb Lin cod rest on cliff edges for current to bring them prey! It's amazingly frightening that wall an rush of water, a submarine might just pass by! The Rock your touching is America, the space your looking out into is Not!
