It is no secret that the cold winter months can be hard on your body, and there are several reasons for this. First of all, the winter months are the coldest of the year, with many regions experiencing well below-zero temperatures. Exposure to these extreme temperatures can be damaging to the skin and joints, making joints more susceptible to arthritis flare-ups and skin more prone to cracking and flaking. Furthermore, the cold days also come with less daylight, and it is through sunlight that we get some vital nutrients and vitamins, such as vitamin D. Without enough vitamin D, people can become lethargic, feeling fatigued and lacking the energy they need to do the things they normally do.
