Growing hair long for the 1st time & its giving me headaches

LITERALLY!

so long story short, but I have been growing my hair long and it has now crossed my waist length,but these days I randomly get headaches and my head actually feels like it is not getting enough blood circulation.

I have stopped doing ponytails cause of this, and mostly either braid them or leave them open but it's so annoying. How do people with long hair manage?

If it helps, I have wavy hair that looks puffy but is not very voluminous
