Data show that winter is the peak season for fractures in older adults. Why are elderly people prone to fracture in winter? First of all, the cold climate, low temperature and short sunshine hours in winter reduce outdoor activities for the elderly, resulting in insufficient ultraviolet radiation, insufficient vitamin D synthesis, lack of muscle exercise, reduced blood circulation in the bones and easy precipitation of calcium from the bones, which aggravates the process of osteoporosis and makes the bones less strong and rigid, which can result in fractures if they are slightly touched and fallen. In terms of the external environment, there is more rain and snow in winter, more days of snow and ice on the roads, smooth roads, bloated clothing, and degenerative changes in the organs of the elderly, increased organic diseases, slow movement, slow reaction, reduced vision and hearing, the elderly are most likely to fall, resulting in fractures. The main prevention of fractures in the elderly is osteoporosis. The main thing to prevent fracture is to prevent osteoporosis, “the bone reserves of people will gradually decrease after the age of 45, but the rate of reduction is closely related to the intake of calcium in the diet, genetic factors, nutritional status, lifestyle habits, etc., so both men and women should be supplemented with calcium.” When it comes to calcium supplements, people think of those calcium supplements advertisements. Of course, the elderly can take some calcium supplements in moderation under the guidance of their doctors. However, in the long run, to prevent or delay the occurrence of osteoporosis, the elderly should eat more foods rich in protein and vitamin D, and supplement the necessary calcium through diet, such as shrimp, soybean products, nuts, milk, etc., especially milk, which is high in calcium, if you insist on drinking a glass of milk every day, the effect may be better than “surprise calcium supplementation”. It is best to combine winter exercise with “sunbathing”, such as walking outdoors, to receive sunlight and promote the synthesis of more vitamin D in the body to assist in calcium absorption. Older people also need to change some bad habits, because research shows that long-term smoking, excessive alcohol consumption, less movement and more sitting and low-calcium diet, etc., are likely to trigger osteoporosis. Falling is the most direct cause of fractures in the elderly. The elderly are more active indoors in winter, so the first thing we must consider is “indoor fall prevention”: to keep the indoor temperature above 10 degrees Celsius, so that the elderly wear less clothes and move around lightly; house furnishings and the placement of things, in order not to hinder the elderly walking principle; tables and chairs and other furniture should be stable, not swaying and shaking; pay attention to the floor and shoes It is better for the elderly not to wear slippers; the lighting of stairs, aisles and bathrooms should be sufficient, and the ground should be kept dry to prevent water accumulation and icing; bathing places and toilets should be installed next to the handles for the convenience of the elderly.
