A person's constant feeling of cold with age

Dr. Muhammad Hafez Ibrahim

American scientists from the US Food and Drug Administration have discovered that with age, the number of immune cells responsible for restoring body heat decreases when temperatures drop . . The study indicated that it is these same cells that help maintain normal metabolic functions. Therefore, the elderly are more susceptible to infections and problems in the metabolism process . As it is known, the person has an innate protection from degrees Low temperature Any thermoregulation mechanism based on the ability to generate thermal energy from fat stored in the body, but with age people feel cold more .

Scientists at Yale University and California University in San Diego have discovered that immune cells stored in fat are the reason for this . Where researchers came to this conclusion, when they wanted to know why adipose tissue contains immune cells whose presence is usually concentrated in areas of the body Most susceptible to pathogens such as the pharynx, nose, lungs and skin. And it became clear to them, after the study, that fat contains only congenital type II lymphocytes , which restore body heat in low-temperature conditions .

The researchers discovered from their study of sequencing laboratory genes of young people And the elderly, that fat tissue with age loses cells . The lack of these cells leads to the body’s inability to burn fats and maintain body temperature in cold weather conditions. After injecting some elderly people with a substance that increases the production of these cells, the immune cells recovered, but the interesting thing is that they became less tolerant of cold . Prof. Dr. Vishwa Deep Dixit, head of the research team, says that if we can restore something lost, we will restore the body’s function to normal. But this did not happen. Because instead of increasing the number of healthy cells, the growth factor eventually doubled the bad cells, which remained in the fatty tissue of the elderly.

Immune cells not only protect against pathogens, but also help in maintaining the immune system, adds Prof. Dr. Vishwa Deep Dixit. on normal metabolic functions. But with age, the immune system changes, so we have to be careful when manipulating it to restore the health of the elderly. Because what is good in youth can become bad with age.

The feeling of cold varies from person to person, and although women usually suffer from cold more than men, but the British Health Authority experts believe that the constant feeling of cold may be due to pathological reasons that may not occur to mind. As there are reasons Several about feeling cold all the time, the most important of which are:

= Anemia : It occurs when a person does not have enough red blood cells circulating and carrying oxygen throughout the body, and its symptoms include: – Feeling cold in the hands or feet. Weakness or tiredness. Dizziness or lightheadedness. – breathing difficulties. Increased heart rate. – Headache. Pale skin.

= Hypothyroidism : Cold intolerance is a well-known symptom of hypothyroidism, which occurs when the thyroid gland doesn’t produce enough hormones to help regulate metabolism and temperature. Symptoms of hypothyroidism include: – Feeling cold. – Tired. Melancholy Constipation Menstrual problems. Decreased heart rate.

= Disorder in blood circulation : Blood flow has an important role in the body to regulate its temperature, and a disturbance in blood flow may increase the feeling of coldness in the feet and hands. There are several factors that affect blood flow in the body, including cardiovascular diseases. In the event of a weakness in the heart and blood vessels, it becomes difficult for the heart to pump blood effectively in the fingers and toes.

= anorexia nervosa : Anorexia nervosa is an eating disorder characterized by insufficient weight loss or weight gain and a distorted body image. Those affected restrict eating intensely, or exercising excessively, which may cause a person to develop intolerance to cold due to insufficient body fat, and other symptoms include: – Weight loss. Stomach problems, such as constipation or colic. Difficulty concentrating. Dizziness or fainting. Decreased period when menstruating. Dry, brittle hair or nails. Poor wound healing. Intense fear of gaining weight. Fear of eating in public places. – Social isolation.

= Raynaud’s disease : Raynaud’s disease affects the arteries in the fingers, toes, or both, and these arteries become narrow, reducing blood flow. During these episodes, fingers and toes turn blue or white and as blood flow returns, fingers and toes can become red, numb or painful, and cold temperatures and stress lead to Raynaud’s attacks.

= lack of sleep at night : Lack of night sleep leads to many problems in the nervous system and affects the balance of body temperature regulation in the brain. According to a study conducted by the Finnish University of Jyväskylä, researchers tested the effects of sleep deprivation for an hour on 20 a young man who participated in the study. The body temperature decreased in young people as a result of sleep deprivation.

= Peripheral Artery Disease : Peripheral artery disease occurs when plaques build up in the arteries that carry blood to the rest of the body, and cause them to become narrower, which means Difficulty for blood to flow through. It often causes reduced blood flow to the extremities and consequently feeling cold, numbness, tingling, or pain in the hands, feet, or both, and in severe cases, it can cause tissue death. )

= diabetes : often The exacerbation of diabetes leads to what is known as peripheral neuropathy, and the symptoms of this disease are numbness and pain in the feet and hands. Because the affected nerves are responsible for sending body temperature signals to the brain, diabetics can feel permanent cold in the feet and hands.
