Hyperfocus and heartrate

[Grondhammar]

In my early 20s I went to my GP and told her that I consistently had a 35-45 bpm heartbeat that would lead to heart palpitations. Instead of an eyeroll, she responded by asking and listening. We determined that I was experiencing this at times when I was very focussed on some activity. It didn't matter what it was... walking and pondering something, chopping wood (and again, pondering something), cooking, typing, reading.

Over years of self-observation, I came to realise that, at those very focussed times, it was like my body just forgot to breathe. I'd notice that my breathing had stopped, and almost like I was observing myself would wait and suddenly my body would decide "time to breathe!" and my heart would jump back to 65-70 bpm -- thus the palpitations.

I've learned to manage this by applying meditation techniques and body awareness. But it still surprises me sometimes.

Has anyone else experienced this?

I have Central Sleep Apnea, where my nervous system goofs off and doesn't tell me to breathe when I'm sleeping. But I have also observed times (focused on something, as you said), where I realize I haven't been breathing because of the sudden intense need to do so. Maybe there's only so much bandwidth, and silly things like breathing get out-prioritied by more interesting stuff.

I always had low blood pressure and a slower heart rate than most.

When I was 19 I had an extended stay in a hospital to have a growth removed from my chest, and in there the nurses got all excited about my sleep patterns and they called in a specialist to study me. They said that what I do is much closer to hibernation than what most people think of as normal sleep. My heart rate slows, my blood pressure drops and my body temperature drops.

I've always been a very heavy sleeper and rarely remember having any dreams.

Sir, you are a bear.

Many years ago on a freezing cold winter's night the girl I was living with had pulled more and more of the covers over herself in her sleep. Eventually she fed the entire lot over herself and on to the floor next to the bed.

All of a sudden having no cover at all woke her up. She said at first she was blaming me for stealing it all but she got scared when she reached across me looking for where it all was. She said my body was really cold to touch. Then she turned the bed side lamp on to see what was going on and she said my whole body had gone blue in the cold. That freaked her out, she thought she'd killed me, and it made it worse when it took a long time to wake me up.

From my point of view, I had just been woken up in the middle of the night for no reason I could fathom and I wasn't too happy about it.

I know from experience that when my body thinks it needs help it wakes me up again, I'm quite sensitive to shifts in weather and a big change will wake me up straight away every time.
