Yes, it is a know fact that cold weather can cause your blood pressure to rise. It's very common. My blood pressure is controlled very well, but I too see an increase from 100 - 105/65 to about 110/70 when it gets cold.
Hope this helps.

Thanks for your comments. I have been taken Vastarel MR for 10 days now, 2 tablets a day (70mg /day). I am not sure if this is rising my BP also. I am going to cut down to only one tablet (35mg) a day. I take this to control some cervical dizziness. It has helped me but I am afraid if it is rising my BP.
