Why do older people have trouble sweating?

Age-related changes in sweat glands

As people age, their sweat glands undergo a number of changes that can make it more difficult for them to sweat. These changes include:

* Decreased number of sweat glands. The number of sweat glands on the skin decreases as people age. This is due to a combination of factors, including genetics, sun exposure, and smoking.

* Smaller sweat glands. The sweat glands that remain become smaller as people age. This means that they can produce less sweat.

* Reduced sweat production. The sweat glands that remain produce less sweat as people age. This is due to a combination of factors, including decreased blood flow to the skin, decreased nerve function, and hormonal changes.

Other factors that can contribute to sweating problems in older adults

In addition to the age-related changes in sweat glands, a number of other factors can contribute to sweating problems in older adults. These factors include:

* Medical conditions. Certain medical conditions, such as diabetes, heart disease, and kidney disease, can interfere with the body's ability to sweat.

* Medications. Some medications, such as antidepressants and antihistamines, can also interfere with the body's ability to sweat.

* Dehydration. Dehydration can also make it more difficult to sweat. This is because the body needs water to produce sweat.

Risks of sweating problems in older adults

Sweating problems can have a number of risks for older adults, including:

* Heat-related illnesses. Sweating helps the body to cool down. When people are unable to sweat, they are more likely to develop heat-related illnesses, such as heat stroke and heat exhaustion.

* Skin irritation. Sweating helps to keep the skin moist and healthy. When people are unable to sweat, their skin can become dry, cracked, and irritated.

* Infection. Sweating helps to wash away bacteria and other contaminants from the skin. When people are unable to sweat, they are more likely to develop skin infections.

If you are an older adult and you are experiencing sweating problems, talk to your doctor. They can help to determine the cause of your sweating problems and recommend treatment options.
