you are correct. When you give blood you shouldn't do cardio or work out. But drawing a vial of blood for testing will not effect your workouts.

I am kind of the same way as you. I hate needles but I finally decided to give blood and "make a difference". I was fine afterward and walking, sitting, eating a cookie, etc. Then I was waiting on another friend of mine to finish and...yeahhhh just started seeing little black dots...lol. So they made me lay down and hang out a bit.
But while they were taking the blood, they said no extreme cardio, workout, etc for 24 hours.

Drawing blood for a test is not enough blood loss to exhibit faint and dizziness. It's usually a vaso response. Usually, when a person does that during a blood draw they recover as soon as the needle is removed. It could possibly be sore where they stuck you depending on what size needle and if they dug or just stuck you... I would think you are perfectly fine to work out. You haven't lost enough blood to be concerned. Now if you donate a unit of blood that is a different story..(I'm a Med Tech.) emoticon

they didn't take much blood. maybe a tablespoon, even if it went into a few vials. the idea of having blood taken can be quite distressing.

it's been long enough for it to be well clotted, so you don't have to worry about it starting to bleed while exercising.

since you're not feeling well right now, that's the bigger sign that maybe today you need to take it easy. if you're feeling better now, a good walk could well be the thing to do.

i hope all your labwork comes back normal.

After you donate blood, you're supposed to avoid exercise and heavy lifting. I accidetally went running one day a few hours after I gave blood (wasn't thinking) and that did not go well!

It was just for blood tests, but last year I didn't lay down when they took blood and I started to cold sweat and feel nauseous and almost passed out. This year I laid down but I've been feeling weak all day. Plus my arm is SO sore where the needle was. I'm worried that if I do cardio I'll feel sick and if I do weights (it's not a weights day anyways) I'll get a big bruise.

Go on how you feel. Likely you are dizzy just from fear/mental issues... because the amount of blood taken for simple blood tests at the clinic, really isnt enough to make you feel dizzy as if you had donated a pint of blood at a blood donation center. So, it's safe medically really to exercise. But if you dont feel up to it...just dont do it.

How much blood did they give? If it's not a blood donation, just for blood work, it's probably a lot less. But if you are feeling not quite up to it, it's best to err on the side of caution.

I try to workout before giving blood, a few hours at least, because I never feel up to par afterwards! If you feel any soreness or tightness, DO NOT exercise. Dont feel bad, you did a great thing already! Just drink LOTS of water!!!

Thanks! That's what I thought, but I tend to over do it sometimes so hearing someone else say it helps me not hurt myself!

If you feel weak after giving, yes, you should nix cardio or any strength training. You can save your workout for tomorrow when you feel at full capacity and not fatigued.

If you feel fatigued now, err on the safe side.

I had my yearly physical this morning and I had to get my tetanus shot (since I'm 25) and get my blood work done. I have to lay down when I give blood because I get faint and feel nauseous. So I'm feeling a bit weak now and my arm is really sore where the needle went in. Should I skip cardio today?
