Why do I feel lightheaded after exercises?

Causes. Feeling dizzy or light-headed is often a result of your body not being able to get enough blood and oxygen to your brain. Feelings of nausea could be caused by your body not having enough calories in your system to compensate for the amount of physical activity you’re doing.

One of the common causes of feeling faint after a workout is simply overexerting yourself. Pushing your body too hard can result in your heart working too hard and not getting enough blood to your head. You may also feel dizzy if you haven’t been hydrating your body during exercise, or have been exercising in the heat.

TIPS: Don’t overtrain / Cool Down don’t just stop / Hydrate

    Why do I feel like I was about to faint after working out even though I’ve never experienced it before? And after working out I quickly fall on the ground although I have eaten before doing the workouts

    I go to a tennis camp and every time when I’m warming up I get dizzy. My vision gets blurry and I am crazy tired. I not even working that hard out there. It got so bad, last year I fell to the ground and almost passed out.

  15. Jacob Lavilla on January 4, 2022 at 5:20 pm

    Working out while fasted gives the best results. Eating prior to working is not necessary and I
    Recommend not eating prior to workout just stay hydrated. This is all of course if your cutting/losing weight .

  16. Mark Mallorca on January 4, 2022 at 5:20 pm

    I done 50 minutes workout 🤒

  17. Caleb Tieman on January 4, 2022 at 5:20 pm

    High blood pressure and too much caffeine can do this too. I know this from experience.

  18. Kimochisus on January 4, 2022 at 5:21 pm

  22. Zell the lone wolf on January 4, 2022 at 5:25 pm

    Thanks I was wondering why I was light headed and stumbling around after I did the treadmill

  23. Jesse Kline on January 4, 2022 at 5:28 pm

    I don’t know if anyone’s still watching to be able to answer my question. But today I was trying a freeway style bench press. And I don’t know if that’s what it’s actually called. But I noticed that with the free weights it was a lot harder than with a bar. And I started kind of getting this feeling that I was going to black out while I was doing it like I was seeing little things in front of my eyes. But I didn’t black out. And I went ahead and strained to finish. Afterwards I felt light-headed the rest of my workout. And I still kind of feel a little light-headed and weird. Does anyone know what this could be?

  24. Uma Baraik on January 4, 2022 at 5:28 pm

    When I do cardio, I feel burn in my diaphragm and I feel extremely light headed for some time. Am I fine??

  31. Jbird on January 4, 2022 at 5:35 pm

    Hey man, I’ve always stayed in the gym and biked and such, since 15, now I’m 45. Just took a year off, well did some hiking and jogging before summer heat.

    After lots of beer, bad food, bad sleep, cigs now and then………….the weather is good and decided to ride the bike.

    So today I hiked the dog a few miles, then napped, then lightly rode bike for 30 minutes.

    After riding I was just nauseated and light headed for about 30 minutes.

    Pretty normal after not working out for so long?

    I’ve never gone that long.


    Getting used to higher oxygen again, blood pressure changes…?,,,,,…..

  32. Rapture Ready on January 4, 2022 at 5:35 pm

    The girl looks light headed out of the three!

  33. Petalgirl on January 4, 2022 at 5:36 pm

    I felt like these guys were yelling. Too loud. Tone it down a bit fellas. You don’t need to be loud to be enthusiastic.

  34. Ismail TNI Sanusi on January 4, 2022 at 5:37 pm

    eat, drink and wait two hours before a workout. I hope this works.

  35. Anand on January 4, 2022 at 5:39 pm

    I only feel dizzy after training legs every once in a while, do you think it’s because I didn’t warm up enough? Or have a big enough meal?

  36. memoranda1 on January 4, 2022 at 5:40 pm

    i have recently been feeling light headed when running and i never felt that sensation before. it wasn’t even hot outside, there is a breeze and plenty of shade all around. but after 15 mins of running i start to feel dizzy and i’m not even heavy…i’m 5’6 140 lbs. no chest pain just dizzy and i feel like fainting…i’m not even pushing my body to its maximum potential..just light jogging.

    well we all know that and yet there are some of us who still have this problems but its hard even to think about givin up the training.

  47. Laudiceia Silva on January 4, 2022 at 5:52 pm

    Hi Mikey and Sabrina. I have been experiencing quite a lot of head rushing during my exercising. I am not sure my PT is pushing me to hard. I can do more repetition on a lighter weight I think, than heavy weight with more repetition. As sooner I pushed the heavyweight my head just pumping on the top of my head. Please give me some ideas what to say to him😔 thank you

  48. Iridium night on January 4, 2022 at 5:52 pm

    Did a workout today in my school weight training class and my teacher had us on high rep sets. I did heavy weight with those high reps and I was dead. My vision went blurry I was feeling weak and light headed. And ontop of that out gym is in a portable building because our school is being remodeled and we have no water.

  49. Shawn Antunes on January 4, 2022 at 5:55 pm

    Make sure you are breathing properly

  50. Anønymøus Víds on January 4, 2022 at 5:57 pm

    I feel light headed lifting weights. I’ll try to be hydrated before I do it. coz sometimes I push too hard to the point where my entire face goes red.
