Your feet are prime targets for eczema triggers like dry winter air or hot summer days. And flares on your fingers and toes can be itchy and painful. So give these parts of you a little extra TLC. Are your feet often dry and itchy? Your socks may be to blame. Synthetic fabrics and wool can irritate your skin. For everyday wear, choose 100% cotton socks, preferably ones that have not been dyed. Also, change your socks a couple of times during the day if your feet sweat. Damp socks can make eczema worse.
