In the winter, when the back is especially often caught on it, you can put coals from the spruce and thoroughly wrap it with a warm blanket on top. In general, in order to always remain healthy, you need to go to nature as often as possible. For such trips, we recommend that you buy a boat in St. Petersburg. Buying a boat is a responsible step, so take it with all seriousness. Choose only a trusted company, for example, such as SPEV, which is constantly developing and has many years of experience.
