I've had a few scattered episodes over the years while running or doing boot camp-type things. In the first incident, I actually passed out, which led to a medical investigation that concluded, "Don't worry - sometimes these things happen."
After that I was more cautious if I felt it coming on. In each case, there was some combination of:
1) Sudden cessation of leg movement or a major leg effort, both of which result in more blood in my legs than my brain, and
2) Heat and/or dehydration.
I doubt oatmeal with brown sugar is the problem. If anything, sugar helps my brain feel sharper later on in really long runs.
Good luck with it!
Train with me Super. I know CPR.
Train with me Super. I know CPR, I do sugar - but really, I just think you would be fun to train with!
Hey, do you have low BP? I have crazy low BP (family thing it seems) and find that has often been the culprit to my lightheadedness in movements done when beyoncing.
Yes, measured in the high 30's sitting st my kitchen table by a nurse who visited for insurance ten years or so ago but when I exercise I can hit 200.
And yeah dude. Super fun. Ask mike.
The sudden cessation of leg movement kinda fits. I was switching from a slow reverse pull up ( a let down?) to rest to a cable weighted lunge thingy. I had just come off the let down thing and was talking to the trainer and was having a hard time following the conversation and was barely keeping balance.
I know that sensation! Agreed, low BP is the real cause, whether it's chronic or temporary. The conditions linked to my episodes were things that cause low BP, e.g.:
- Dehydration = lower blood volume and thus less blood in your noggin.
- When you're too warm, more blood flows to the capillaries in your skin, away from other body systems
- When you exercise hard, those muscles demand more blood but they also pump it back to your heart as they contract - until they don't, and the blood pools there temporarily instead of going to your brain.
- I get orthostatic hypotension sometimes - low BP and dizziness when I stand up, e.g. it might happen if I'm doing pushups in a warm gym, then jump to my feet to do the next exercise.
I've read that the passing-out type of lightheadedness can be a cardiac symptom but in athletes, it's usually (but not always) benign. It's usually fine if it happens at a time when you are standing up immediately post-exercise - more likely to be a concern if it happens while you're in the middle of exercising.
It is not uncommon to swoon in the presence of Beyonce.
