The effect of the equivalent of 2-3 cups of coffee on aortic stiffness was measured using ultrasound on 10 patients with high blood pressure who are taking blood pressure medications. Blood pressure increased by 11/5 mm Hg at 30 min and remained elevated for at least 3 hrs after caffeine administration. No increase was noted with placebos.

Much has been said about sun protection, but how much do you retain?

Key Points:

1) Apply 30 min to sun exposure.
2) Apply 2-3 times per day (no exceptions).
3) Wearing a hat helps.
4) Sun damage can occurred on a cloudy day.
5) SPF only measures UVB, not UVA.
