Quoted: Folks, I you are out in the heat, drink lots, and lots of water. I go through a gallon and a half a day when working out in the South Texas sun. Wear proper attire, including a wide brim hat. Oddly, a full brim hard hat is one of the best hats to wear in the sun as it allows for air circulation around your head and the plastic doesn’t transmit heat in to your scull. I typically drink 1 electrolyte drink, usually LiquidIV, for every two quarts water. I try to take a water break every 30-45 minutes. I've gotten more serious about it since I take cholesterol meds as they cause cramping enough on their own. I worked outside in the heat for several hours yesterday and expected cramps overnight but I had none so I guess what I'm doing worked. |

Quoted: Ah! OK thanks. Because an actual IV is some next level shit that can go bad wrong if you don't know what you're doing! So I was like.. damn some folks take ot to the next level. Quoted: Quoted: Quoted: You have liquidIV? It's a brand name of an electrolyte water additive. Quoted: It’s why we keep it in the house. In a pinch slamming 3-4 gatorades work as well. Try some of those Vitalyte packets. There is one downside to Vitalyte. It has sugar and no preservatives, you can't mix it up too far ahead of time or it will go sour. It goes sour pretty quickly without refrigeration. I used to get the Lemon flavor but it has almost no color, so a water bottle with it mixed in is almost indistinguishable from plain water. Ah! OK thanks. Because an actual IV is some next level shit that can go bad wrong if you don't know what you're doing! So I was like.. damn some folks take ot to the next level. Mom was crna. She would have poked me and put saline into me if I was in wife’s shape. |

Was out kayaking fishing yesterday, from 0730 to 1500. I don’t drink all my water because it got too warm. I wore a wide brim hat, long sleeve silk weight shirt, shorts and 50spf sunscreen. I felt dead when I got home and needed up drinking lots of water. No cramping though, just thirsty. I normally go through lots of water daily, but when it got warm I couldn’t drink it. Today I picked up a Yeti soft sided cooler to go on my kayak. Should keep my water cooler than what I was using. Going to look into that liquidiv also. ETA: Tomorrow my team is coming in for a meeting. I’m surprising them with Klein hard hats that have a fan with ducts on it to keep cool. I’ve been pushing heat related safety on them with these high temps. Maybe this will help. Heat is no joke! |

I have one that I fill full of ice, top off with water, then I too off with water bottles throughout the day. It will keep ice all day while you're out on the water. |

I have worked hard in very hot weather. I try to pre-hydrate before I go out, and try to stay reasonably hydrated, but I think the most important thing is to listen to your body. Maybe it doesn't work for everyone, but try to pay attention to your body. My body normally tells me that it is status ok while I work, but after working intensely in the high heat for a quite a few hours, suddenly I felt I should go inside and hydrate NOW. Don't ignore it when you get feelings like that. I went inside, drank a lot of water and some salt, potassium, and other electrolytes, and I was fine. I actually felt from my body that I needed electrolytes and not just water. Took a rest inside for 15 or 20 minutes, then went out and did some more yardwork. I just think many people pay attention to external things like their phones, but don't pay attention to the signals that your body is giving you. Try it, it's how your ancestors survived before the internet and OSHA. |

Quoted: Both heat and electrolyte imbalance are cumulative. Quoted: Quoted: It wasn’t just today that put her in trouble. Yesterday started it. Both heat and electrolyte imbalance are cumulative. Yep. Today pushed her over the line. It’s when she recalled that her sweat wasn’t salty today that I put 2 and 2 together. Hindsight and all. She was in trouble before she even started playing. |
|
Pregaming it is essential. If you're not hydrated when you start work, you're already behind the curve. I still get heat headaches sometimes no matter how much water and electrolytes I ingest. Correct clothing can really help too. Light synthetics with an open weave make a breeze feel like an air conditioner because of evaporative cooling. That effect is less pronounced in high humidity. I always throw an insulated jug of cold water on my machine and keep salt tabs in my lunchbox and in the truck first aid kit. Running open-cab equipment and damn near sitting on top of the hydraulic coolers and engine gets a bit toasty. |

Quoted: I just think many people pay attention to external things like their phones, but don't pay attention to the signals that your body is giving you. Try it, it's how your ancestors survived before the internet and OSHA. A big part of it isn’t that they aren’t paying attention; it’s that they don’t understand how potentially serious things can get, so they’re deliberately ignoring the signs for dumb reasons (whether it’s a man with a dangerous, “Just suck it up” mentality, or a woman with a “I don’t like having to pee so often, especially in public restrooms” type crap, or, “Lemme just push through it and get this done”). |

I didn’t think of something like that before. I’ve been filling up non insulated water holders to go in the cooler. I’m going to give that a go. Thanks! |

Quoted: ...I just can't even. I love peeing. When I couldn't pee was a horrible experience and I couldn't see urologist fast enough. I can't imagine wanting to not pee, ever.  Quoted: Quoted: I am seeing an odd trend recently where several of the women that I know have told me that they don't want to drink anything because they don't want to have to go pee. My own mother literally told me that (while she was in the ER for severe dehydration so bad it was messing with her kidneys.) Since when has the fear, the outright terror of urinating started to overshadow their actual health? PSA Guys, make sure your women are taking in proper fluids when they are in the heat and don't accept a lame, fake "I'm not thirsty." ...I just can't even. I love peeing. When I couldn't pee was a horrible experience and I couldn't see urologist fast enough. I can't imagine wanting to not pee, ever. Finally, something men and women can agree on!

Quoted: I keep a banana bag and an IV kit at the house for such emergencies. The real trick is getting one started on someone who is that dehydrated.  Get a "boa band". It is TQ used for starting IV's that you literally roll down the arm and inflate the veins. Kind of like squeezing all the left over toothpaste in the tube to the top. The military came up with them to make it easier to start IV's in the middle east when troops were dehydrated on top of whatever else was going that they needed an IV. |
| Glad she's okay, my wife has spent two weeks in the hospital in the past year from dehydration, but it was pregnancy related. Once before and once after the birth. So far everything has been smooth sailing the past few months, but we've definitely decided on no more kids. |

Quoted: Saltwater with awful taste. Try something a little more appealing so you can actually drink enough of it to make a difference. You also need potassium, magnesium and calcium which isn't in there. The product now called Vitalyte started out in the 80's, made by a Doctor that worked with SoCal rescue folks. They did testing and found that oral consumption of the drink mix he came up with was about 90% as effective as giving an IV. Giving people IVs out in the field in a rescue operation has some significant hazards, so something that's close in effectiveness without those hazards was a real improvement. IV saline generally does not have any potassium, magnesium or calcium either for electrolyte balance. You're not kidding. We had a guy take the first flight to Chicago to go to a jobsite in the middle of summer. He ate no breakfast and only had a couple of cups of coffee. By mid-day, he fainted and the EMTs gave him an IV and took him to the hospital. Three days later, he had a red streak climbing up his arm from the IV stick site. MRSA, yay! IV antibiotics for a month.

Quoted: I spent four hours in the heat yesterday. I had maybe 20-24 ounces of water with me but slammed over a half gallon of cool water with salt added to it once I was home. Have to be careful chugging ice cold water when dehydrated. Typically your blood pressure drops when dehydrated and too much cold water in stomach results in the body pulling blood from extremities trying to warm it up. I learned that lesson the hard way. I came in after 8 hours in the sun knowing I was dehydrated and slammed a 24 ounce water from the fridge. Sat down at my desk and started to feel light headed and weak. Then I started to slouch over and could barely move. Called my wife and tried to check my blood sugar since I hadn't eaten anything that day either. Pricked my finger and no blood came out. Pricked multiple fingers multiple times and couldn't get a drop of blood. Put the pulse/oxy meter on my finger and it said "insert finger" as it couldn't find a pulse. Threw on my blood pressure cuff and it so low that if it dropped any lower I would need to get to the ER. All because I chugged a large quantity of ice cold water why severely dehydrated. Hydrating throughout the day with electrolytes is important. You can buy over priced stuff like LMNT or just add some salt and take a magnesium and potassium pill with the water. |

Dang OP. That's not good. I was at an airshow taking pics one time, it was hot, I stood up to take photos of the Blue's and my eyesight went away. It took me an hour of laying in the shade before I could walk out of there. Scared me pretty bad. I've been prone to heat exhaustion since my Army days. It gets worse as I get older. |

Quoted: I hated the taste of gatorade until the derecho in 2020 when I was doing 4-6 hours a day running a chainsaw. bought cases of it, slammed it warm from the car. tried it cold, just caused stomach cramps. when I was club roadracing motorcycles in my 30s I would slam a gallon of water after each track session. had a friend whose gf had to be driven to the er on two different weekends because of dehydration. some people just don't learn. Military taught me well about dehydration, I’m constantly guzzling Gatorade/ water, etc. I sweat ridiculous amounts, I look like I just fell into a pool, pants soaked to my knees, wring out a shirt and fill a glass 1/2 full, it’s insane. Working outside I’m hauling a cooler of Gatorade on my tractor, atv, truck, etc and force myself to drink it thirsty or not. Never fallen out due to heat / dehydration either. |

Quoted: She came home from playing 1.5 hr of tennis in dangerous heat. She did the same yesterday. Her hand was locked up, she couldn’t stand, cramping all over. Shit. She’s in real trouble. Had her slam a few liquidIV. I was this close to taking her to ER for banana bag. Electrolytes/salts. It’s what bodies crave. Stay careful in this heat, it hit her quick. Mid 50s short of a plane crash in the middle of a desert, how in the world can anyone be so un aware that they become that dehydrated seriously  |

Saw that the other day and was seriously considering testing that. Whenever the ingredients arrive (ordered on Amazon. Some are scheduled to arrive this week. Some stated in the listing that they ship in 13-14 days. I wasn’t in a hurry), I’ll test several things: 1) just how long they’ll continue to stay cool in the $26 vest (the vest looks exactly like the one in the video). Thermal capacity is dependent on both the material’s properties, and the mass, so I’ll list the size of the pouches I use, and the weight/quantity I use in each pouch (haven’t ordered the pouches, as they don’t list the size of the pockets). 2) can they really be recharged just by laying them on the cool concrete in the basement? How long does that take? That’s also dependent on the temperature differential. The greater the differential, the higher the thermal transfer. 3) how quickly they recharge in a regular refrigerator, or freezer (eg. This will give me an idea of how to estimate usability. Eg. If pouches with X mass of the PCM stay cool for ~2.5 hours of yard work/cycling in YY ambient temperatures, and they can cool in a 35f refrigerator in ZZ minutes, then I can keep 2/3/4 sets of packs to rotate if I need to be in hot temperatures for a certain number of hours). If the testing/measurements pan out, I’ll post up a thread in GD, with the data. As mentioned, this could be HUGE, IF it works as claimed, for anyone who has to work in hot conditions, or even things like a hot weather power outage. |

As mentioned by various posters in this thread, people don’t understand that you need more than just water when you’re sweating profusely. Learned that lesson a long time ago, biking and hiking and bringing just straight water to rehydrate. Nope. Not enough. Need electrolytes, too. For the 99% of GD who hate reading articles/links, read the link I posted about the SCIENCE of Oral Rehydration Solutions. Here it is again. *** in a nutshell, you WANT some sugar in the ORS, as it helps absorption, but it needs to be the right amount, and the type of sugar matters. You DON’T need magnesium in an ORS. You don’t lose much from perspiration. Anything beyond the key ingredients just slows absorption. If it contains Vitamin C and a bunch of other crap, it’s not an ORS). The SCIENCE of an ORS Does your ORS of choice list the osmolality of their product? If not, why not? Does the manufacturer even know what that is, or why it matters? *** I take Cerasport EX1 during high perspiration activities (135 mOsm/L), and Ceralyte 70 before/after (220 mOsm/L). WHO/UNICEF used to recommend ORSs be no greater than 310 mOsm/L. They’ve since changed that recommendation to 245 mOsm/L, as further testing has shown that the lower osmolality has better absorption for subjects suffering from dehydration. |

Quoted: short of a plane crash in the middle of a desert, how in the world can anyone be so un aware that they become that dehydrated seriously There is something in Alaskan natives dna. When I was young I had no problem with the heat in Montana. After being back in Alaska I cannot take heat over 60f very well. Have to be careful and drink more electrolytes. But having asthma it is a balance as too much liquids will make my lungs watery for lack of a better word. It brings on other problems. |
