Help no success with the hyperventilated drowning method

[versea]

Ive been attempting it since last night. the pool is cold and Im freezing to death. tried it 4 times each time with more heavy breathing than last time.
I dont know what Im doing wrong. I get a mild headache from all the breathing and crying but then when I go underwater nothing happens until I start to drown
could it have anything to do with the water being cold and dirty?
because Im out of ideas at this point
do you have to resist the feeling of drowning before you get unconscious?

Swim & alternate between hyperventilating & holding your breath as long as you can. It's important to swim. Also, you're probably not hyperventilating properly. Check out Wim Hof's YouTube videos
