shallow water blackout: practice 1

[nopointofliving]

I started practicing hyperventilation today.
I breathed in and out for two minutes , then held my breath a bit longer.
Then I felt kinda pressure on my head but I didn't faint.
What am I missing? Or should I practice more ?

Breathe faster, for a longer period of time - 2 minutes is nothing. Make sure you're lying on your bed, you don't wanna get injured

Thank you, I'll try again
