Back in highschool I could hold my breath for around 2 minutes underwater. During this time, I was very fit and active, and was outdoors often.

Fastfoward to now... I can hold my breath for around 3 minutes underwater, and can relatively easily get 4 minutes when breath holding after I first wake up. Although now, I am in my room constantly, no longer fit nor active, and as a result am always indoors.

Both times before breath holding - I would relax for a couple minutes, hyperventilate for a couple minutes slowly, then quickly hyperventilate for another minute, then pack before going under.

Personally I think that staying indoors in a high CO2 enviornment was a factor that led to my adaptation to the constant CO2 buildup within my body. Because as we know, it's not the lack of oxygen that forces us to breathe, but this CO2 buildup.

Also, as I am no longer fit nor active, I believe this could have also played a part... but I am much more skeptical about this.

What should I do to improve my breath holding time? Lifestyle factors? Breath holding techniques? I'm willing to hear.

My last static air hold record was 5min21, after like 3-4 months without much training neither on the bed or on the water, i wanted to try again to see if i still got it, and i actually managed to do 5min30 exactly. Im really happy that i dont loose these abilities even after months of almost no training.

Would you be scared or excited? :D

Hey everyone,

During strong contractions on deeper dives (relative to myself) to ~45m CWTB dives. During the last 15 metres my glottis starts to leak almost like I am gasping for air.

Why? My dives are clean with no major urge to breathe and I don't struggle with glottis control on the descent.

Do I need to strengthen glottis control?

TIA
