Summary
Regular exercise may improve skin moisture in older adults. Moderate to high activity levels were associated with better stratum corneum hydration compared to low activity levels, suggesting exercise as a preventive strategy for skin dryness.
Area of Science:
- Gerontology
- Dermatology
- Exercise Physiology
Background:
- Age-related decline in skin moisture is a common issue for older adults.
- Factors like sun exposure and lifestyle habits can worsen skin dryness.
- The impact of exercise on skin hydration in the elderly requires further investigation.
Purpose of the Study:
- To investigate the relationship between exercise habits and stratum corneum (SC) hydration in older adults.
- To determine if different physical activity levels correlate with variations in skin moisture.
- To inform clinical preventive strategies for age-related skin dryness.
Main Methods:
- A cross-sectional study involving 124 older adults (mean age 84.3 years).
- Physical activity levels assessed using the International Physical Activity Questionnaire (IPAQ).
- Stratum corneum (SC) hydration measured on the forearm; data analyzed using t-tests.
Main Results:
- Significant differences in SC hydration were observed between low and moderate/high physical activity groups (P = 0.001).
- Participants with moderate/high activity levels exhibited better skin hydration.
- The study included 69.4% female participants, with 57 in the low activity group and 67 in the moderate/high group.
Conclusions:
- Exercise habits appear to enhance skin moisturization in older adults.
- Potential mechanisms include improved skin blood flow, stress reduction, better sleep, and increased collagen production.
- Exercise may serve as a preventive strategy against age-related skin dryness and functional decline.

01:19The Effect of Aging on Tissues
3.1K
Several body functions deteriorate with age. The external signs of aging are easily identifiable. For example, the skin becomes dry, less elastic, and thins out, forming wrinkles. The skin of the face begins to appear looser due to a decrease in the levels of elastic and collagen fibers in the connective tissue. Additionally, melanin production in the hair follicle decreases with age, resulting in gray hair. Moreover, the senses of sight and hearing decline, so glasses and hearing aids may...

01:23Role of Skin in Vitamin D Synthesis
7.5K
The skin plays a crucial role in the synthesis of vitamin D, a vital nutrient for various physiological processes in the body. Vitamin D is unique because it can be synthesized in the skin through a series of chemical reactions triggered by exposure to ultraviolet B (UVB) radiation from sunlight.
The solar UV B rays (290-315 nm) are absorbed by the skin, and 7-dehydrocholesterol (provitamin D3) photolyzes it to previtamin D3, which undergoes a rapid transformation to vitamin...

01:22Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Absorption
208
As individuals age, their body's physiology evolves, affecting drug pharmacokinetics. The most apparent changes occur in the gastrointestinal tract, where an increase in gastric pH, a delay in gastric emptying, and a reduction in gastrointestinal motility are observed. Remarkably, these changes do not substantially modify the absorption of orally administered drugs, particularly those absorbed via passive diffusion.Transdermal drug delivery emerges as a highly viable method for older adults due...

01:00Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Distribution
215
Drug distribution in the human body is influenced by several factors, including plasma protein concentration, body composition, blood flow, tissue-protein concentration, and tissue fluid pH. Among these, changes in plasma protein concentration and body composition due to aging significantly affect how drugs are distributed within the body. Specifically, aging is associated with a decrease in albumin levels by about 10% and an increase in α1-acid glycoprotein levels. These alterations are...

Age-related pharmacokinetic changes are extensively documented, but understanding age-related pharmacodynamic alterations is relatively limited. This knowledge gap can be partly attributed to the complexity of developing appropriate measures of drug responses compared to bioanalytical methods for determining drug concentrations.Most information regarding age-related differences in human pharmacodynamics originates from cross-sectional studies. However, these studies assume that observed mean...

01:16Sensory Functions of the Skin
7.7K
The skin is the largest organ of the human body and plays a crucial role in our sensory perception. It contains a vast network of sensory receptors that contribute to the skin's protective function by perceiving physical, biological, and environmental cues and generating relevant responses.
There are two main categories of receptors on the skin: capsulated and non-capsulated. The non-capsulated ones are mainly the pain receptors. The capsulated ones can be further categorized based on the...
