Why do many elderly people not survive the winter?

Because winter is the period of high incidence of geriatric diseases. Because the lower outdoor temperatures in winter can induce many diseases. The elderly are more susceptible to these diseases due to reduced body resistance. Among them, tracheitis and arthritis are the main ones in the north.

For example, in winter, due to the large temperature difference between indoor and outdoor temperatures, it is particularly easy to trigger colds when going in and out. If the resistance of the elderly is not strong, a severe cold will be very harmful to the body of the elderly. And it is easy for colds to induce many diseases.
