One of the changes the body experiences when aging is known as “immunosenescence.” In essence, the immune system fails to react as quickly to infections as it used to. Not only do the “first responders” slow down in reaching a site of injury, but also the skin itself becomes thin and less well-supplied with blood, thus making any wounds heal slower.
This trend is also indicative of a person’s general lifestyle: slower healing can lead to a fear of falling or getting hurt, which in turn leads to less movement and more isolation. It’s a cycle that feeds itself.
Monitor the medicine cabinet. Make sure they have everything required to care for their injuries and that they remain well-hydrated. Being dehydrated is a big cause, and easy one to rectify, of delayed healing and skin problems among older individuals.

Changes in Circulation and the Rhythm of Breath
Finally, the last symptom is often the least apparent but can be the most serious. This would be the well-known “cold hands” problem. You may see your loved one wearing a sweater on an otherwise warm day or always wanting a blanket. This could mean that there are some changes in their circulatory system. The heart may not be pumping quite as vigorously to the extremities.
Another sign that you may see is the way that they breathe. Their breath may get very shallow or even exhibit a “sighing” rhythm. Although this is common with the elderly, it becomes more important to be aware of if there are any blue nails or if they suddenly feel dizzy.
These subtle alterations in temperature control and respiration can be addressed by having better body movements and ensuring that the environment remains “draft-free,” as recommended by the American Heart Association. This is because the aim is to stay within the “thermal comfort zone,” which will ensure that the energy of the body is used effectively.

Conclusion
Looking at this list, do not see these five warning signs as “problems needing solutions,” but rather as markers showing you what your loved one is experiencing right now.
Age is not a disease, nor an illness. It is merely another phase of life that becomes more challenging when done in isolation. And the best support you can give to an older person does not necessarily mean a solution, or even a professional intervention—it means your presence.
