Apple Watch Is Overheating
Just like your iPhone, your Apple Watch might start to overheat sometimes. As you know, this will make your wrist feel uncomfortable at best, but it can also damage your Apple Watch in the long run.
If that happens, you should take your Apple Watch off immediately. It’s best to turn it off and wait until it completely cools down. While it’s overheating, avoid putting it in its dock, as charging might be one of the reasons why that’s happening.
Afterward, try updating your iPhone and your Apple Watch. A bug in the software might cause an overheating issue. If your Apple Watch is still overheating after updating, it’s best to take it to Apple support and ask for help.
Your Apple Watch may have a hardware issue, and the only way to fix it is to have it checked out by professionals.
