It\u2019s not often that something can be good and bad for you at the same time, but researchers at the University of Edinburgh have found something that\u2019s just that. Something that can lower your blood pressure but will have doctors jumping up and down.<\/p>\n
Scientists were looking for a way to treat some of the nutritional deficiencies that can boost blood pressure to unsafe levels, when they stumbled upon some fantastic benefits of what every health professional will warn you away from. <\/p>\n
Tanning beds increase your risk of developing melanoma by 75%, but amazingly, the UV light in this \u201cfake sunshine\u201d was found to be great at reducing high blood pressure too.<\/p>\n
The study saw volunteers receive the light therapy on two occasions. One time they got bright, warm lights, the next they were exposed to UVA. <\/p>\n
Researchers discovered that diastolic (second number) blood pressure dropped by an average of 2 to 5 mm\/Hg after they\u2019d been bathed in UVA light.<\/p>\n
And the effects lasted too. After one-hour, diastolic pressure still hadn\u2019t increased, so something was definitely happening, but what was the cause? <\/p>\n
One theory was that UVA light might have done what sunshine does, and increased their vitamin D levels, but this wasn\u2019t the case.<\/p>\n
So, why was diastolic blood pressure dropping so significantly then?<\/p>\n
It turned out to be down to lower nitrate levels in the skin. These are some of the most harmful free radicals, and they\u2019re present in certain foods and can be breathed in from smog.<\/p>\n
The fact that tanning beds cut down on these horribly destructive substances is great news, but the fact that they\u2019re tanning beds is not. So, while it\u2019s really interesting what this research has thrown up, please don\u2019t reach for the tanning goggles just yet if you want to save the skin, you\u2019re in. There are much safer and healthier ways to reduce your blood pressure.<\/p>\n
