What you drink can help lower your blood pressure.
Caffeine has been shown to adversely affect blood pressure, but you can still have your java if you switch to decaf.
Caffeine tightens the blood vessels and causes stress to have a greater impact on your blood pressure.
You can swap out at least some of your coffee for tea to see rewards too.
Hibiscus, chamomile, and other teas have a calming affect which helps to lower stress, as well as contain antioxidants that help lower blood pressure.
Hibiscus in particular may have an additional bonus in that it contains phytochemicals that have been linked to improved blood pressure as well.
