I know I can. Just with thoughts and meditation. Actually I though everyone could do it and was surprised that this is even newsworthy. I expose myself to cold since my childhood (check out Wim Hof method for some practical examples and the scientific explanation) and can heat myself when I need it.
I remember some memories where I had a dog, he was cold and shaking after swimmimg, embracing him.
He still kept shaking and when I thought of a thing that made me feel warm (kind of shivering/vibrating feeling) and goosebumps he immediately stopped shaking. After a few seconds he starts shaking again. Repeat this process on countless occasions, always the same result.
Yup. I totally know what works as I've experienced things myself.
But it's kind of hard to set up scientific methodology to prove things with n = (enter convincing amount of subjects) where there are many subjective sides in the experiment (e.g. Thinking of something that makes you shiver/goosebump is hard to apply at scale as for many that is result of something subjective and different for each individual)
I'd love to see some organization to set up an experiment though.
False, it's not difficult at all to set up even minimally rigorous scientific experiment. Now you might not like the results that you gather from the experiment, so I would imagine that it's in your best interest to not pursue and gather actual objective evidence.
Take an infrared thermometer, point it at the part of your body that you're visualizing heating up. Observe the results. Took me five seconds to come up with this experiment.
The hard part was obviously not measuring temperature.
It's communicating people how to visualize/think of something that gives the feeling. Because the feeling is subjective and even I as the person experienced it have hard time explaining it. It's much harder to explain it to others and make sure they did correctly.
I don't need results anyway, I _know_ it works so there isn't a chance that "I won't like" the results. I just want more people to benefit and an incorrect experiment may block them, not me, from proceeding further.

Why would you? It works, it's a teachable method. To my mind, the inquiry doesn't have to progress far beyond that. Unless perhaps you value doing things solely for knowledge, which is something academia stopped doing ages ago (and arguably never really did).
