Diving Seal Reflex

Do human beings have a reflex diving like a seal?
I asked that question before and people said no. Then I did an experiment in same. I'm in pretty good shape and exercise daily, but I'm 51 years old. After working out for an hour, took a sauna too hot, and I my heart rate to 160. I had a heart rate monitor. Before doing this fills me with my "soaking tub" with cold water and three 40-pound bags of ice. I got into him and held his breath and wet throughout the body including the head. My heart rate went from 150 to 52 in about 45 seconds! I felt very dizzy and the whole room was spinning around for a while. I kind of felt pretty good for a while, but he left and was tired all day. I think I have shown that people Humans have a diving reflex! No, I am not a stamp. It was what I did is dangerous?
Umm … that doesn't sound good man. 150-52? follies
