i've been practising in the school's lower basement practice rooms for many hours everyday for the past 3 weeks since my unversity life started. It's always really cold down there and i've been practising cold-handed a lot. everytime i would start practising with my hands icy cold and after 3-4 hours my hands would still be cold. i've been experiencing some soreness in my arms which i had never experienced before prior to coming to the faculty of music. does anyone know whether or not it's good to be practising cold-handed? i heard from a friend that it actually helps to improve the technique but it also can result in injuries very easily. thanks!!!
