In our daily lives, we may notice a special smell on some elderly people, which is often referred to as "old man smell". So, how exactly does this taste come about?This article will look at the causes of changes in body odor in the elderly from a scientific point of view.
First of all, we need to understand that the smell of the human body is mainly affected by two aspects: sweat and bacteria on it. When we sweat, sweat is expelled from the pores, and the bacteria on it break down the proteins and fatty acids in the sweat, creating a special smell. As we age, the body's metabolism gradually slows down, and the perspiration function of ** will also be affected, which may be an important reason for the change in body odor in the elderly.
Secondly, as we age, the body's immune system gradually weakens. This makes older people more susceptible to bacteria and viruses, which increases the risk of infection. Infection not only causes inflammation, but can also alter the type and number of bacteria on it, further affecting body odor.
In addition, older people's ** often becomes thinner and drier, which may also affect body odor. The thickness and wetness of ** can affect the evaporation rate of sweat, which in turn directly affects the production of body odor. As a result, thinning, drying out may cause sweat to stay on the surface longer, increasing the concentration of body odor.
Finally, the lifestyle and eating habits of older adults may also affect body odor. For example, some older people may have bathed less frequently because of health problems or changed their eating habits due to changes in taste, which can affect body odor.
In general, the causes of body odor changes in older adults are multifaceted, including slowed metabolism, weakened immune system, thinning, dryness, and changes in lifestyle and eating habits. However, this does not mean that older people should put up with this body odor. By practicing good personal hygiene, bathing regularly, using skincare products that are appropriate for their skin type, and maintaining a healthy lifestyle and eating habits, seniors can effectively control their body odor.
