    Careful with tanning beds!

    5 Oct Careful with tanning beds!



    JAMA Internal Medicine

    Artificial tanning beds pose an additional risk for the health of our skin and lead to the development of melanoma. However, millions of people throughout the world continue to use them, despite the warnings of doctors and health authorities. A new scientific study confirms the seriousness of the problem.


    This blog has frequently highlighted the health risks posed by artificial ultraviolet (UV) light tanning, mainly because they represent a high risk factor for developing melanoma, the most aggressive of the skin cancers. We are not alone: medical associations – pointing to irrefutable scientific studies – have been warning that this practice is the direct cause of the dramatic increase in skin cancers witnessed in recent decades, especially in white women.

    Washing your hands is a must

    15 Sep Washing your hands is a must



    The New York Times

    Mother always nagged us to “wash your hands”. And she was right. The skin of our hands carries the germs that cause various diseases. But that simple and healthy habit is less widespread than you might think.


    Most of us form part of the group of people who do not wash their hands enough or properly. The medical profession recommends that we wash our hands with soap for at least 20 seconds each time we visit the bathroom, after we return home or get to work and, above all, before cooking or handling food. Research by Michigan State University (USA) was based on discreet observation of 3 749 users of public toilets. Over 10% did not wash their hands at all, while 23% of those who did so did not use soap. A mere 5.3% spent more than 15 seconds washing their hands. And men washed about half as often as women. Millions of people get sick each year from eating contaminated food; the study authors say that this would not have happened to half of them had hands been washed properly.

    Energy-saving bulbs affect the skin

    4 Sep Energy-saving bulbs affect the skin



    British Journal of Dermatology

    Our skin is the shield that protects us from external aggressions. But ultraviolet (UV) light can pass through it, affecting its internal layers and causing photoageing and possibly even greater damage. Modern energy-saving bulbs, unlike the traditional incandescent and new LED lights, emit UV rays that can damage the skin.


    European Union scientists have long warned that energy saving bulbs, known as compact fluorescent lamps (CFL), may have negative effects on the skin’s health because they emit ultraviolet (UV) rays like the sun. In fact, at distances of under 20 cm these effects appear to be demonstrated, especially for people with previous skin problems. Fluorescent lamp manufacturers state that quality products have a dual layer that reduces the radiation, leaving it too weak to cause skin cancer. But, just in case: buy reputable bulbs and keep your distance!
