Dear woofmum, you mentioned in a post that your high bp was at least partly due to the air fresheners in your room. Why? How did you know? My bp has increased considerably in the last 2 months and even though my meds have been increased they have not had any effect. currently about 170/105 average - and this is scary. I would really appreciate any info. on supposedly 'safe' stuff that affects bp. I cannot work out why mine is still not responding to meds and has increased. However, I am going now to take the air fresheners out of the bedroom. Thanks in advance.
