This is one of the simplest, effective & cheapest way to cool down during the heatwave which we are having in the UK at the moment. Today the temperature where I live was in the 20s. So turn of the air conditioning/fans and just get yourself a water bottle.
Place the bottle in the freezer for a few minutes and as the picture shows roll it under your bare feet. Of course, you can also do this with your socks/tights on. This will cool you down and as an added bonus will also massage your feet so helping to relax the rest of your body. What could be better than that. You'll feel refreshed & it only takes a few minutes.
