The heat waves across the US and Canada have been…hot hot hot! What are your tips for staying cool and managing T1D when the temperatures rise? As a sibling of someone with T1D, I always make sure to pack enough food and drinks for everyone when I’m having a get together to make sure we can address any sudden lows or dehydration.
What do you do to Beat the Heat?
A fun treat that we use are the Deebee’s Orgnanic Freezie’s. They are sooo good!!! They have really good ingredients. 25 calories and only 7 carbs. They taste amazing, even I eat them haha. They are popsicles and come in 3 flavors and all are good. You should definitely try them. You can even order them off their website or if you have a Smiths store nearby you might find them there. 
I always make sure to bring water bottles that keep the ice cold all day long so that I always have really cold water available on hot days. I also read that holding a cold water bottle in your hand when exercising in the heat can help you feel cooler in extreme heat. For snacks, frozen grapes are a delicious a healthy treat!
i jump in a lake. There are many lakes in my area so I ride my bicycle to my favorite one and swim. I don’t do anything different for heat or for cold except maybe dress appropriately. I do have to adjust basal rates in the spring and fall. I also design special refrigeration systems as part of my job. Some of these chambers are 40F, others 0F, and then the special ones are -40F, -100F and -300F so if I’m feeling I’m a little hot, I could go stand in one of those… …though probably not the -300F one… probably not. 
Keep your age and overall health in mind as you spend time in the sun. I love fresh air and the great outdoors but can’t tolerate heat as well as I could when I was younger (I’ve gotten my Joslin award for 50 years with diabetes, to give you an idea😊) so I make sure I have access to a cool place rather than spending hours outside as I used to.
I’m reminded of a story I read of man who enjoyed tennis. He played several times a week but was starting to feel bad following games - something he wasn’t used to. He saw his doctor and was carrying a huge water bottle with him. Most people carry around 20-some ounce bottles but his was much larger. Long story short, it turn out in his efforts to stay hydrated, the quantity of water he was drinking was flushing important chemicals out of his system, and that was causing him to feel ill.
Here’s an article that may be helpful. Many athletes drink Gatorade (there is a sugar free version) in lieu of water (or perhaps alternate) to replace electrolytes that may be lost with sweat.
I’m not a doctor so like to encourage people to do their own research, so do check it out for yourself to see if you want to make athletic drinks part of your kit.
Since we live in Phoenix these high temps are norms for us . But now that we have a son, who is Type1, I am all the more cautious. We always bring ice cold water with us wherever we go and plenty of snacks. I pick inside activities to do with the boys so we use someone else’s AC. This morning we were at the Phoenix Zoo by 6:30 am and stayed for a few hours before it hit 100 degrees at 9:00am. We go to the gym and use their pool (until ours is built). We just do A LOT of indoor activities or stay inside the house all day.
It should start to cool down for us by October 
so we can start going outside again! Hope this helps!
I keep powdered lemonade mix in my locker and a half liter bottle of water in the fridge at work for lows on hot days. Normally I go for skittles or an energy bar, but when it’s really hot and I’m sweating buckets something sticky or chewy is the last thing I want. It’s also nice that I can make it as sweet (or not) as I need it to be, depending on how low my blood sugar’s gone or how active I’m expecting to be.
