At a breathwork workshop last year I learned about the Sitali Pranayama technique. It’s a breathing practice that is supposed to cool your body down.
It’s actually good you remind me of it, summer is close here in Albania and I sure get the chance to test it myself 😅 I’m not good with heat as well.
Is that the moon breath? Left nostril breathing?
Found this instruction, it’s better than me trying to describe it ^^ https://www.mettayogastudio.com/metta-blog/sitali-pranayama
