“The causes of cold feet in the elderly in summer are as follows: cold feet in the elderly are commonly caused by atherosclerotic stenosis or occlusion of the lower limbs, varicose veins and vasculitis of the lower limbs, hypothyroidism, hypotension, cardiac insufficiency, diabetic peripheral vascular disease, anaemia, malnutrition and oedema.
Cold feet in summer is mainly due to the fact that in hot summer weather, elderly people are weak, have a poor appetite, eat less, sweat more and do not replenish nutrition and water in time, which can easily lead to reduced blood volume and malnutrition, resulting in impaired blood circulation, reduced peripheral blood flow and cold feet, which is more likely to occur if there is an associated underlying disease.
Older people, because of their weakness, have a certain degree of decline in the heart’s pumping function and circulatory capacity, and are not able to pump enough blood to all parts of the body and recycle it. The feet are at the end of the limbs and are furthest from the heart, so it is easy to have poor blood flow and cold feet.
