Tricks for getting succulents through the summer, using ice cubes to cool them down really works

My sister uses ice cubes to help her succulents "get through the summer," and this trick is worth trying.
The last time I took photos of my succulents must have been over half a month ago, and by now the plants have changed a lot, the bright colors have all faded, replaced by a plain "vegetable green." Counting on my fingers, this should be the fifth summer I've gotten through since I started growing succulents (thanks to netizen Fang... for the material)
I still remember when I first fell into this hobby, I bought a bunch of succulents but heard they were hard to get through the summer, and for a while I was panicking and at a loss, asking everyone everywhere for little tricks to get them through the summer. Now, I no longer worry about getting succulents through the summer, because I've adapted to the four-season changes of succulents. In the height of summer, even if some succulents die, I can already face it calmly.
Quite a few succulent friends ask me how to get succulents through the summer, and my answer is usually this: on hot days, shade them in good time, make sure there's ventilation, and during the plant's dormant period, don't water too wet or too thoroughly. Will doing all this mean no succulents are lost? No. Plants also follow nature's laws, survival of the fittest, and we don't need to force it.
Is there really no good way to help succulents get through the summer? Actually, there is. Take my sister: she really takes extra care of her succulents, and normally even if I give her a single leaf, she'll tend it very carefully. When summer gets hot, to let her succulents get through the summer coolly, she even fills several large plastic bottles with water, puts them in the freezer to freeze, then takes turns placing them around the succulent plants, and then uses a small fan to blow air. It really has a cooling effect; even standing where the succulents are kept, I can feel the coolness.
But since I have to work, I don't have the time to do this. Succulent friends who have the time really can try it. Compared with the summer methods I mentioned, obviously my sister's way of getting succulents through the summer is a bit more "clever."
Not only that, some of the succulents were moved by my sister to the indoor balcony, and when it gets hot, she opens the balcony sliding door and uses the air conditioner to cool the succulent plants down. My sister says that compared with losing a beautiful succulent, using a bit of electricity is nothing.
Succulent friends here, have any of you tried using ice cubes to cool down your succulent plants?
