I understand what you may be going through, but unlike the other responses, I beleiev it may be more than just warm weather. You my have a thyroid condition which is precipitating the response. Also some hypothalamus issues may be at play. I work with a few patients who have issues like yours - usually male late 30's to 50's who notice it because they run/workout a lot. I have also seen this in some diabetic patients.
I dont share all of that to scare you but perhaps getting looked at by your local physician and having some simple tests done may give you a peace when it comes to this.
