To get really grumpy after exercise?

[Trewser]

I thought exercise was supposed to chill you out. I've just run 5k on the treadmill. Really enjoyed it while I was doing it. Got into the car with dh afterwards and felt so irritable and grumpy. I'm still a miserable cow now. I get like this after Parkrun also. Why??

It's the sugar crash from eating sugary carbs

Yeah you need to eat something! I'd HIGHLY recommend the Barebells protein bars, they taste AMAZING, they'll fix you right up :)

That's really not on. If you can't control your temper, get some help

Yes, that's why I am asking here. I don't have a temper! To be fair 'snapped' was a bit strong, I just wasn't super friendly and ecstatic like most finishers. Just grumpy looking and muttered 'thanks'. But I agree, its not great. I don't think a gp would be interested in me going in and saying 'Hi, I am very friendly and positive and motivated 99% of the time but when I've run quite hard I am grumpy for 30 mins' Doubt that would refer me to CBT training!

It's the sugar crash from eating sugary carbs

So I'm thinking this might be right as I had two sugary things about 2 hours before going, because I thought the sugar would help. And I don't eat much sugar as a rule. Maybe I will try no sugar whole earth peanut butter on a bit of wholemeal toast instead and see if that makes a difference. Cranks Organic wholemeal loaf is amazing.

That it is an OK excuse to be irritated and snarky? why on earth would you think that? I don't like being irritated at all, and I am not snarky, just go very quiet.

user1493413286 yes, I didn't wind down properly as I had to go and pick up dh. Obviously you don;t have time to wind down at parkrun either. I think I will make sure I do that, AND take some sort of snack/drink that might help. Maybe if I wander off by myself and have a drink/snack before giving in my barcode I can alleviate it at parkrun also.

Looobyloo that sounds so similar! What do you eat before and after?

Hungry I expect. I'm off to the gym shortly and taking a flapjack for the walk home.
TBH I never get a runners / exercise high or anything. I work out to keep healthy. I'm still a miserable bugger .

megletthesecond LOL

@Trewser before parkrun I don't eat but if I'm doing a half marathon race I'll have a bowl of porridge usually. I can't normally eat after a rade for hours as my appetite goes but if I'm grumpy I force something sweet down me. Doesn't always work though.

I don't get grumpy but I can feel pumped/ angry sometimes after exercise. For example if someone were to start on me I'd be quite up for a fight, I sort of feel invincible I think, maybe it's the endorphin rush or the increase in testosterone that exercise can produce. Btw I've never ever had a fight and never will, but it's funny how it can engage that part of your brain.
