Cortisol/Adrenalin Surges

[milly]

I usually workout early in the mornings e.g. 5-530 a.m. and have recently done a few HIIT classes early evening 6.30 p.m.
I have noticed that after these classes body has so much adrenalin or cortisol running through it, that I find it extremely difficult to sleep at night. body feels as though it is overheating on the inside and I am on a natural high. It is taking at least 48 hours for body to get back to some sort of balance. However, I am still continuing with exercise regime. So even if I do a class at night, I am still getting up early next day to do weight training.
Don't like the effect evening training has on body. Any idea what is going on? Not advisable maybe. I am in 50's

Hey Milly, good to speak to you again and good to see you're still strong and working hard at it .

I'm not sure what you can do about this, unless you do the HIIT in the mornings if you have a couple of spare mornings when you don't lift and assuming that won't mean training 6-7 days a week.

An alternative would be to ditch the HIIT and go for intervals, either that or reduce the intensity of the HIIT, do it for less time, or both.

However as you are getting these sensations when you do it in the evening, then I would say it's purely down to the HIIT and not for other reasons, like you developing some kind of hormone / hypothalamus related issue.

Hi Bossman, Thank you for reply.

Yep, only get these adrenaline spikes in evening. May get them in mornings too, but too active with life in general during day to notice. Only aware of it when I am resting...and that's another story

Still at it hard and strong. Fitness I think is in DNA, could not imagine life without it.
