It is annoying to have low blood pressure after a riding more so in the summer even though I drink plenty of water!
Hopefully not too dangerous, although once I had to stop while riding as I was so lightheaded I had to lay down and drank water!
The medication that I take for a non functioning thyroid was increased and did speedup my resting pulse substantially to the high 40s low 50s!
I feel better knowing I am not the only one!
