I have been doing hot foot bath for about 2 months. First I soak my feet in a bucket full of hot water. After water gets cold I add more hot water so my feet always feel very hot. I usually do it for about 20 minutes (it is said that doing it for half hour to 40 minutes is the best) and after that my body feel very relaxed.
It really helps my sleep! I highly recommend this method to those who have trouble to sleep and whoever's feet are always cold.
