I'm addicted to the feeling of breath holding

大家好，我是新人。
最近我正在尝试维持呼吸到极限。其他人也开始表示，在正常过程中（没有深呼吸），我的解决从一分半钟开始，我坚持到4:30分钟。之后，我觉得我很享受这个过程，收缩的时候感觉很兴奋。这个现象可以吗？为什么我的收缩持续了3分钟，但我没有昏过去？
Look forward to your advice.

Everyone is a little different. Contractions can feel different in different situations. For me empty lung contractions on land are unbearable. Full lung contractions on land are usually unpleasant but manageable, but occasionally I will have a day they really don't bother me at all. I almost never get contractions underwater at depth and when I do they don't bother me at all.
Contractions and blacking out are not directly related. I've gotten hypoxic symptoms as early as 3 min and as late as 6 min. I've never pushed it to LMC or blackout.
