Electronic address: sperlich@uni-wuppertal.de.AbstractOBJECTIVE: The aim of this study was to investigate thermoregulatory, cardiorespiratory, metabolic, and perceptual responses while running in a hot environment (31.7° ± 1.0°C; 42% ± 3% relative humidity) and wearing T-shirts made from different fiber types.METHODS: Eight well-trained men performed 4 tests wearing either a T-shirt made of 100% polyester with 4, 6, or 8 channels, or one made of 100% cotton. Each test consisted of 30 minutes running at 70% of peak oxygen uptake, followed by a ramp test to exhaustion and 15 minutes of recovery.RESULTS: There were no differences in skin, core, and body temperatures between fiber types during submaximal and high-intensity running (best P = .08). During recovery, body temperature and shivering/sweating sensations were lower when wearing 4- and 6-channel fibers (P ≤ .04) compared with cotton.

The relative humidity at the chest and back were lower for all polyester T-shirts compared with cotton during and after submaximal and maximal running (P ≤ .007). Heart rate (best P = .10), oxygen uptake (P = .95), respiratory exchange ratio (best P = .93), ventilation (best P = .99), and blood lactate concentration (best P = .97) did not differ between the fiber types. Nor were any differences in time to exhaustion (best P = .76), ratings of perceived exertion (best P = .09), thermal sensation (best P = .07), or sensation of clothing wetness (best P = .36) discovered.CONCLUSIONS: Although statistical analysis revealed lower shivering/sweating sensations while wearing 4- and 6-channel fiber shirts during recovery, with an improved chest and back microenvironment for all polyester T-shirts, the question remains whether these differences are of any practical relevance because the performance of the well-trained men was unaffected.Wilderness Medical Society.KEYWORDS: clothing; thermoregulationPMID: 23870763 DOI: 10.1016/j.wem.2013.04.005 [PubMed - indexed for MEDLINE] Publication TypesRandomized Controlled TrialResearch Support, Non-U.S. Gov'tMeSH TermsAdultBody Temperature Regulation/physiology*Clothing*Energy MetabolismHot Temperature/adverse effects*HumansMalePerception/physiologyTime FactorsFull Text SourcesElsevier ScienceClinical Key

The no-excuses elimination method, has spawned legions of Konverts who devote vast amounts of time to kondo-ing their lives top to bottom.

The best-selling book that started it all is easy to digest (and infectious…you will literally start itching to toss stuff), though its central thesis is kind of hard to stomach at first: Unless you truly, deeply love an item, it has no business in your home. This means the first purging session can be rough, but the euphoria that comes with unloading a single bag of unnecessary clutter makes going H.A.M. on the rest of your space easy. We’ve laid out the basics below—along with an illustrated guide to her folding technique, which we found impossible to figure out based on the text alone. (Meanwhile, we gave it to some friends to spur donations for our annual goop closet sale.) When deciding what to discard, remember that the endgame isn’t to throw out or donate as much as possible, but to make sure that the things you hold onto make you happy. This is where picking up each item and asking, “does this spark joy?” comes in. It may sound like a hazy benchmark but with practice, it becomes an invaluable tool.

It’s particularly effective for organizing closets as we often develop superficial attachments to clothing (I paid a lot for this, I wore it when I met my husband, maybe if I lose 10 pounds), not really considering if the shirt, dress, or pair of shoes serves a purpose. Sort and purge by category rather than by room. While your instinct may be to start in say, the kitchen, and then move onto the living room and so on, it’s best to pick a category (clothing, books, documents, etc…) and go from there. The reasoning is that similar items are likely scattered throughout the house, not confined to one room. After discarding, designating a specific home for every single item you keep is critical in avoiding a clutter relapse. According to Kondo, fancy stackable storage solutions encourage hoarding, so simple and easy-to-use options are best. Ideally, it should be just as effortless to put something away as it is to locate it later. The KonMari Folding Method Arguably the most revolutionary Kondo tidying tool is her folding technique.

The instructions are complex, though, which is why we illustrated it below. In short: Rather than haphazardly laying things flat in a drawer, they should stand upright; the more folds there are, the less wrinkled the item will be once ready for wear. While the space-saving benefits are pretty far-reaching, Kondo’s other objective is to grant clothes—everything from coats to sweaters to socks—the respect they deserve by touching, appreciating, and properly storing each item. Lay socks flat as a pair, one sock on top of the other. Fold the toe inward about an inch from the top. Fold in to the center. Fold in half so it stands upright. Underwear(the same process can be applied to bikini bottoms, briefs, thongs, and boyshorts) Lay underwear flat in front of you Fold in half lengthwise, crotch to waistband. Fold in the sides. Fold over crotch again so it stands upright. Lay tee down flat in front of you. Fold in the right side with the sleeve flat.
