In the warm living room, many people still feel the cold of their hands and feet, as if the warm spring sun has not driven away the cold in their bodies. This perennial feeling of coldness makes people wonder: is this a born constitution, or is there some kind of unnoticed health hazard at work? When we put our palms close to the stove and expect warmth, should we also think about the deeper reasons behind it?
The constant feeling of cold in the hands and feet is often mistaken for a simple physical problem. However,This phenomenon can be an important signal that the body is trying to send. Physical factors do affect an individual's sensitivity to cold to some extent, but a persistent feeling of cold may also indicate circulatory problems or abnormalities in the endocrine system. Especially in the absence of external cold stimuli, if the hands and feet still feel cold, then this may point to the failure of the blood to carry heat to the ends of the body, or the slowing of the activity of endocrine glands such as the thyroid gland, affecting metabolic rate and body temperature regulation.
The quality of blood circulation is directly related to the temperature regulation of various parts of the body. Good blood circulation ensures adequate oxygen and nutrients to all parts of the body, while taking away metabolites and maintaining body temperature balance. Poor blood circulation, especially in the extremities, can lead to cold hands and feet. Ways to improve blood circulation include moderate exercise, such as brisk walking, jogging, and eating foods rich in omega-3 fatty acids, such as deep-sea fish, to increase the elasticity of blood vessels. In addition, regular limb massages can promote blood circulation and improve cold symptoms. However, if the cold hands and feet do not improve despite lifestyle changes, then this may be a sign that the body needs to be evaluated by a professional to rule out other underlying health problems.
The thyroid gland is a butterfly-shaped endocrine gland located in the front of the neck, and it secretes thyroid hormones that have a vital impact on the body's metabolic rate. Hypothyroidism, the lack of thyroid hormone production, leads to a decrease in metabolic rate, which in turn affects body temperature regulation, manifested by persistent cold hands and feet. In addition to the feeling of coldness, hypothyroidism may be accompanied by symptoms such as fatigue, weight gain, and dryness. Diagnosis of hypothyroidism is based on blood tests that measure the level of thyroid hormone in the blood. **Usually includes supplementation with synthetic thyroid hormones to restore normal metabolic rate and thermoregulation.
The health of the cardiovascular system directly affects blood circulation, which in turn affects the temperature of the hands and feet。The heart's ability to pump blood determines how well it can be delivered to all parts of the body. Cardiovascular diseases, such as arteriosclerosis or high blood pressure, can lead to narrowing of blood vessels and a weakened ability of blood to flow to the extremities, resulting in cold hands and feet. The key to maintaining cardiovascular health is a healthy lifestyle, including a balanced diet, regular exercise, weight control, smoking avoidance and limiting alcohol consumption. For individuals with pre-existing cardiovascular disease, following the doctor's **advice**, symptomatic**, can help improve blood circulation and reduce the symptoms of cold hands and feet.
