Today midway through my morning run i started feeling very dizzy and light headed, it only lasted about 15 seconds but it scared the **** out of me, mind you i'm a major hypochondriac and every little thing health related or something like that becomes a huge thing to me. a couple of questions to you guys that run: Did this ever happened to you? could this be a heart related problem? should i keep doing my runs? thanks for the help guys.
Might have been a mixture of stress & overexertion, or a sudden drop in BP. Did you have caffeine in the morning? Are you getting enough sleep? Is your nutrition good? It could be anything, but I don't think it was heart related. If you experienced heaviness in the chest/dull aches or odd sensation in your left arm/neck or chest,- that would have been alarming. If you're really concerned, go to the doctor and have him run a stress test & ECG
Most likely just need more water and not OVER do it. I run in 3 Marathons a year and I've experience it plenty of times don't worry to much
