I tend to sweat like crazy in the summer. Never did prior to PD. Cold doesn't bother me much except for the purple mottling on my skin ( a side affect of Amantadfine) gets worse.

When it's hot it's normal for us to feel weak. You have to stay
In a cool place. Do not worry. Drink plenty of water and move slower

I guess difference ppl has difference reaction to heat. The heat (or directly under the sun longer) really makes me slower and hence the symptoms worsen and the cold seems to keep me more stable but my core (body) has to be warmed though. I'm still not willing to give up golf yet even though I'm terrible at it. So, I'll wear a cap to avoid direct sunlight and also try to avoid "hot" temp without ventilation/air flow.

My PD disappears when it's hot.. we don't have much hot weather in the UK so we travel so that I can keep warm....I use a hot tub every day....when the weather is cold I can't stop shivering

Yes, the hear fatigues me.
