In recent years, there has been a fundamental shift in our understanding of the innate chemistry of the body and the role the microbiome plays in shaping it. Individual chemistries, the molecular makeup of our bodies, are influenced by a multitude of genetic and environmental factors. Some are known to have a profound influence (in particular, diet), while the roles of other factors such as the clothing and products we wear on our skin are less well explored. With growing awareness that what we put in and on our bodies affects our health and wellbeing, little is still known about the impact of textiles on the human skin.
This article explores the multifaceted benefits of "diet t-shirts," encompassing both compression wear and innovative fabrics like silver-threaded textiles. We will delve into how these garments impact your body, from athletic performance and recovery to potential effects on your skin microbiome and overall well-being.
Compression Shirts: Enhancing Performance and Recovery
Compression shirts have become increasingly popular among athletes and fitness enthusiasts alike. They promise a range of benefits, from improved performance to enhanced recovery. These snug-fitting garments are not just for professional athletes. Whether you are looking for a legging for a yoga class or a supportive compression shirt to wear to work, there’s something for every need and taste.
How Compression Works
Compression shirts work by applying graduated pressure to the muscles and veins in the upper body. The pressure is highest at the extremities and gradually decreases towards the core. This compression helps to push the blood back to the heart, enhancing the flow of oxygenated blood to the muscles. This is crucial for maintaining healthy circulation and reducing the risk of swelling in the extremities. Compression shirts exert compression through the use of elastic materials that have high stretch and recovery properties. These materials are strategically woven or knitted to provide targeted compression to specific muscle groups. Compression shirts are available in different compression levels, which correspond to the amount of pressure exerted by the garment. The pressure gradient determines the compression level, with higher pressure at the extremities and lower pressure at the core.
To offer the right amount of stretch and compression to the wearer, most manufacturers use a blend of spandex and nylon. However, the ratio can vary. There are some tees where non-stretch panels crafted of nylon are used for maximum support and shape. From the tank style to long-sleeved ones, tees with standard crewnecks to plunging V-necks, you will find a wide variety of compression tees.

Benefits of Compression Shirts
Improved Blood Circulation: The tight fit of compression garments promotes better blood flow, which can enhance oxygen delivery to the muscles. Compression clothing boosts blood circulation, which doesn’t directly increase strength but aids in smarter training. Enhanced circulation means better muscle support and stability and less fatigue, muscle pain, and soreness. As the body ages, issues like poor circulation, joint pain, and muscle fatigue become more prevalent. Compression clothing adds gentle pressure which helps with increased blood flow. This physiological effect of this type of support is better balance and coordination, which ultimately reduces the risk of falls.
Muscle Support and Reduced Fatigue: Compression shirts provide support to the muscles and help reduce muscle vibration during physical activities. Compression shirts are designed to provide support and stabilization to the muscles, reducing muscle vibration during physical activity. This can help prevent muscle fatigue and increase endurance by minimizing the muscle damage caused by repetitive movements. Wearing compression clothing offers essential support to key muscle groups, significantly aiding in body alignment. This is especially beneficial for the core, back, and shoulder muscles, all of which are crucial in maintaining good posture. This unique design activates and engages the core muscles more effectively, further reinforcing the proper posture and providing an added level of support.
Enhanced Athletic Performance: Compression shirts have been shown to enhance athletic performance. The supportive nature of compression wear can improve joint stability and proprioception, allowing for better coordination and balance. Additionally, the compression provided by these shirts can enhance muscle power and efficiency, resulting in improved speed and agility.
Accelerated Post-Exercise Recovery: Wearing a compression shirt post-workout can aid in recovery. Compression shirts play a crucial role in post-exercise recovery. The pressure applied by these shirts helps to reduce inflammation and swelling in the muscles, which promotes faster recovery. Compression wear can also help to flush out metabolic waste products, such as lactic acid, from the muscles, reducing post-workout soreness. For athletes, this means less downtime between training sessions, better post-training recovery, and less delayed onset muscle soreness. Weighted compression adds a gentle, continuous massage-like effect to this recovery process. Compression clothing is highly beneficial during the post-exercise period. It accelerates muscle strength recovery after strenuous workouts or physical activities. The compression helps reduce muscle swelling, muscle oscillation, and inflammation, speeding up the muscle tissue's healing process.
Improved Body Awareness: Compression shirts provide a form-fitting, second-skin feel that enhances body awareness during physical activity. This increased proprioception can improve coordination, balance, and overall movement efficiency.
Temperature Regulation: Many compression shirts are made from moisture-wicking materials that help regulate body temperature. Many compression garments are designed with materials that aid in temperature regulation, keeping the body cool in hot conditions and warm in colder environments. This thermoregulation feature is crucial for maintaining optimal body temperature during various activities, enhancing overall performance and comfort.
Potential for Increased Calorie Burning: Compression shirts can increase thermogenesis, which is the process by which the body generates heat. The compression provided by these shirts can help to trap heat close to the body, raising the core temperature. Compression shirts can enhance calorie burning during physical activity by increasing the metabolic rate. The compression stimulates blood flow and activates the muscles, resulting in a higher energy expenditure.
Support for Neurological Conditions: The gentle, consistent pressure provided by compression clothing can be soothing for the nervous system, offering benefits for individuals with certain neurological conditions. Additionally, the enhanced body awareness promoted by these garments can aid in the improving coordination and spatial orientation, which are crucial for individuals with neurological challenges affecting their motor skills. The addition of weighted compression provides even more proprioceptive input.
Everyday Wear: Some people wear compression shirts as a part of their everyday wardrobe.

Silver-Threaded T-Shirts: Exploring the Impact on Skin Microbiome and Chemistry
Athletic wear often uses silver threading to improve hygiene, but little is known about its effect on the body’s largest organ. One of the most common antimicrobial additives is the incorporation of silver ions or nanoparticles. Silver has broad-spectrum antibacterial properties against Gram-positive and -negative bacteria. In particular, X-Static textiles, silver-coated-yarn-threaded fabrics, are currently used in sports clothing for odor control, hygiene, and social comfort, which can thereby enhance product performance. However, the influence of such antimicrobial clothing on the skin microbiome and, especially, the metabolome is largely unknown. By learning about the resulting perturbations of microbial communities or body chemistries, it may be possible to then manipulate the effects, including those on health, by designing the composition of clothing.
The skin is home to an estimated 1012 microorganisms that live and feed on the skin secretions. These billions of microorganisms, including bacteria, fungi, protists, and viruses, form the so-called skin microbiome. The role of the microbiome, in particular, has been uncovered, time and time again, as a key factor in a number of pathologies. There has been an appreciation for the role of skin microbes and their interaction with clothing for aspects such as body malodor. Yet, the ways and effects of altering skin microbiota with clothing and the corresponding effects on health and wellbeing are not known but are a growing subject of research. In large part due to the activity of the microbiome, the skin contains various low-molecular-weight compounds (metabolites). Some of these compounds are by-products of either endogenous or microbial metabolism, and others are implemented as part of the skin’s physiological role. The metabolome along with the microbiome represents the body’s first barrier to external and environmental substances. Through these metabolic pathways the skin transfers topical signals to determine the body’s physiological activities and regulate homeostasis. Thereby, these processes are adapted to various external factors, such as cosmetics, clothing, or other environmental influences. Many of the same enzymes which operate in the liver also inhabit the skin, and as such, the skin is an important metabolically active organ. The skin surface can be sampled to detect and quantify skin metabolites related to diseases, through secreted sweat. Through techniques such as chromatography-mass spectrometry (MS) and other methods, broad-spectrum skin metabolite specimens can be characterized. Consequently, skin metabolome and microbiome analysis can be a useful indicator in the investigation of the effects of various external stimuli. One of these external stimuli is the incorporation of antibacterial agents into a fabric, for example, the use of metallic and synthetic antimicrobial biocides for odor control in textiles. The increase of antimicrobial agents in our everyday products including our clothing has made it difficult to reestablish or maintain the beneficial bacteria that the body would regularly be exposed to in a more natural environment.
Study on Silver-Threaded T-Shirts
In a study, researchers analyzed skin metabolome and microbiome throughout several weeks of wearing the silver-coated-yarn-threaded T-shirt to document the changes caused by the antibacterial effect of silver. Several studies have analyzed the microorganisms associated with body odor and the bacteria present on malodorous textiles. This is the first study to explore the influence of the antibacterial properties of silver-threaded textiles on the skin microbiome and metabolome and their subsequent influence on the textile microbiome and metabolome. The skin’s unique microenvironments were also observed through multiple sample locations across the body. This study aimed to investigate the impact of antibacterial silver-threaded clothing material on the human skin metabolome and microbiome in a controlled manner.
Experimental Design
The experiment took place over the course of 12 weeks for a total of 12 volunteers: six males and six females. Four body sites, chest, upper back, lower back, and armpits, were chosen for sampling because of the most immediate contact with the clothing material. The experiment longitudinally spanned a total of four phases: initial washout, silver-threaded T-shirts, regular T-shirts, and silver-threaded T-shirts again. During the study course, volunteers were prompted to use only the provided skin products to minimize variability.
Key Findings
- Individual and Gender-Specific Changes: The changes induced by the antibacterial clothing were specific for individuals, but more so defined by gender and body site.
- Increased Microbial Biomass: Unexpectedly, the microbial biomass on skin increased in the majority of the volunteers when wearing silver-threaded T-shirts.
- Alterations in Microbial Diversity: Although the most abundant taxa remained unaffected, silver caused an increase in diversity and richness of low-abundant bacteria and a decrease in chemical diversity. Both effects were mainly observed for women. Although the most abundant taxa remained unaffected, silver caused an increase in diversity and richness of low-abundant bacteria and a decrease in chemical diversity.
- Increase in Monounsaturated Fatty Acids (MUFAs): The hallmark of the induced changes was an increase in the abundance of various monounsaturated fatty acids (MUFAs), especially in the upper back. The major change was an increase in the abundance of various monounsaturated fatty acids that were also correlated with Cutibacterium.
- Microbe-Metabolite Associations: Several microbe-metabolite associations were uncovered, including Cutibacterium, detected in the upper back area, which was correlated with the distribution of MUFAs, and Anaerococcus spp. found in the underarms, which were associated with a series of different bile acids. Additionally, Anaerococcus spp., found in the underarms, were associated with different bile acids in the armpit samples.
Chemical Diversity
One interesting finding is a notable decrease in the chemical diversity for samples of all volunteers except one during the silver shirt usage phase. When combined, the differences in Shannon diversity of metabolites were significant and were more pronounced for females than for males. The amount of X-Static silver-threaded yarn was 5% for the female shirt and 4% for the male shirt.
Armpit Analysis
A persistent challenge in skin studies is the overwhelming signal contribution from skin products, especially deodorants. Since the application of deodorants is mostly limited to armpits, the body parts were further considered separately. The textile and the skin chemistries differ in the underarms compared to the textile worn next to it. Notably, a clear separation of left and right axillae was observed for 8 out of 12 volunteers. This discordance was also confirmed by the diversity analysis-the higher chemical diversity in the left armpits of these eight volunteers was observed for both males and females. It is known that there exists a fraction of the population that has distinct microbiomes in their left and right axillae. A number of compound classes that may be linked to compounds of bacterial origin-such as acylcarnitines (organonitrogen compounds), glycerophospholipids, and bile acids (steroids and steroid derivatives)-have been found to have different abundances in the two armpits. Using random forest analysis, it was confirmed that antiperspirant constituents are more abundant in the left armpits, possibly due to more vigorous application. This finding was corroborated by matched clothing armpit samples. Based on the data, it was hypothesized that the contribution to the discrepancy in the chemical diversity is due to the chemical constituents of deodorant but also to differences in microbial ecosystems.
Implications
Overall, these findings point to a notable impact of the silver-threaded material on the skin microbiome and chemistry.
General Workout Clothing Tips
Besides your shoes, there are a number of clothes designed specifically for exercise. For men, a comfortable t-shirt or something that isn’t very restrictive and loose shorts like basketball shorts will suffice. You can even purchase track suits and Under Armour if your activity will take you to the outdoors during the colder months to help regulate your body temperature. It’s important to dress appropriately when exercising to maximize the amount of energy used on your activity. You don’t want to get tired too quickly, and you don’t want to deal with painful ailments from that sort of neglect.
