Hinokami Kagura (sun breathing)

In Demon Slayer, Tanjiro's special technique is sun breathing. With the skill, Tanjiro is able to momentarily up with power/speed, sending (symbolic?) flames through his body and blade.

Breathing techniques do exist e.g. for meditation or sports. But is there an actual breathing technique that comes close to the Hinokami Kagura?

This paper explores a Tibetan meditation technique that could be a candidate.

Check out the credo summary to see how the researchers carried out the experiment and what they found.

But briefly, they found that seasoned practices were able to raise their body temperature through a combination of a breathing technique and mental visualisation.

It's not entirely clear to me why the practitioners do this, but it sounds like raising body temperature is part of the ritual to (supposedly) heighten mental concentration somehow.

Not quite Hinokami Kagura, but cool nonetheless.
