The snow-covered park alley is a sight that encourages couples to go for a romantic walk, whereas parents with children - for some fun with a sled. Both forms of physical activity will certainly have a positive effect on our well-being and health. Frosty aura and snowfall should not discourage us from outdoor activities. A winter trip to the park not only allows us to oxygenate and burn unnecessary calories, but also supports our immune system. After a long walk one should warm up with a cup of warm drink and dry shoes thoroughly.
