Cold like symptoms after exercise

[DP88]

Im a 46 male in average physical condition. After moderate weight training (machines), I get cold like symptoms the next day.
I have a resting heart rate between 85-88 and my heart rate goes up quickly when I start working out ( up to 150). I'm assuming that I am putting too much stress on my heart and this might be causing this reaction (next day sickness).
Any thoughts?
Thanks

When I mention breathing, there's a certain way to breathe when you life weights.  You might not be doing his correctly, and it might be affecting you individually in a way it might not others.

Thanks for your feedback.
My diet is well balanced with sufficient protein (lean) and breathing seems fine.
The sickness mainly only happens after more strenuous work outs that involve weights. I own a Fitbit, which is why I notice the spikes in Heart Rate. I'm just trying to figure out the post work out sickness.
Maybe thinking about it too much, but it's frustrating to get sick everytime I push the exercising a little harder.

One thing that comes to mind, do you breathe properly as you work out?  What's your diet like?  Especially, are you getting enough antioxidants to protect you from the oxidation exercise causes and are you getting enough quality protein to recover?  As to the heart, I've never understood why anyone would check their heart while they do anything or nothing unless they've been diagnosed with a heart problem.  If everything's working fine, why worry?  Focus more on how you're doing this so you can correct the problem, but don't look for problems where there aren't any.  Everybody has quite different heart rates, but it's only a problem if it's a problem.  My heart pumps ridiculously slowly, but until there's a problem there isn't a problem, is what I've been told.  For some, a slow heart rate indicates great health in that the heart is able to do what it needs to do without a lot of work, whereas it can just as easily indicate a need for a pacemaker.  The answer of which is how you're feeling.  You show no signs of heart disease, so I'd worry about the other things.
