BE CALM AND TAT ON
Two 2017 studies have raised new concerns about tattooing. One found the sweat rate of inked skin to behalf that of bare skin, potentially compromising body cooling and your workout. The other discovered ink particles that had migrated to lymph nodes, which play a key role in immunity. Both studies were small, however. Bottom line: think twice before covering great swathes of your body with tattoos like anNRL player. But as for getting a small I-love-Mum heart on your arm, you’ re still in the clear.
