Absolutely, especially if your pokémon isn’t native to Alola. Luckily, what this actually entails can be as simple as providing plenty of shade, preferably indoors, with air conditioning if you can afford it. (A fan will work just as well if you can’t. So would a kiddie pool full of water that your pokemon freezes.) Moreover, keep your pokémon well hydrated, and educate yourself on the signs of heat exhaustion. (Nausea, lethargy, and confusion being the topmost signs. If your ice-type is mammalian in nature, they may also run a fever.) When your pokémon start exhibiting signs of danger, bring them into a cool, shady area and provide plenty of water as they rest. If any of those symptoms worsen, take them to the pokémon center immediately.
That having been said, there’s a chance that your amaura will fare better than most ice-types because of its rock typing and natural hidden ability (Refrigerate tends to cool the air around the pokémon that possess it), but most definitely keep an eye on her for the next few days for any sign of discomfort or exhaustion.
Best of luck, anonymous!
