The doctor told about the danger of reddened hands during frost
Lyudmila Lapa, an allergist, immunologist, and internist, warned of the danger of reddened hands during the cold. In frosty weather, some people may become more allergic to cold, which is also called cold dermatitis. It is manifested by redness of the skin, itchy spots, prone to peeling and cracking.
As the doctor explained in an interview with Radio 1 on Tuesday, February 3, ignoring redness and itching on the hands can lead to infection and the subsequent spread of infection throughout the body. The doctor explained that in the absence of care, ulcers form on the skin, which become "entrance gates" for infection, which can cause diseases to occur more often and last longer.
The specialist emphasized that an allergy to cold does exist and is associated with an overreaction of the immune system to exposure to low temperatures. She explained that the reason is a deficiency of protective components in skin cells and untimely care: cracks appear, the integrity of the skin is disrupted, blood vessels become inflamed. Sudden temperature changes, she says, increase the vascular reaction and lead to edema.
The expert added that in the autumn-winter period it is important to wear gloves in a timely manner and regularly use greasy moisturizers to protect the skin of the hands.
