Wearing a Bra: Is it Good or Bad? To bra or not to bra…that is the question. There are some people defend bras tooth and nail. Other people think you should only wear one during certain times of the day. Then there are those people who think they’re completely useless… So which is it?! In today’s article, we’ll take a closer look at whether wearing a bra is good or bad. The effects of bras on women Jean Denis Rouillon, a doctor from the University of Franche-Comte, has been studying the effects of the bra on women for years. His research is based on analyzing, observing, and measuring the breasts of volunteer participants while allowing each one to describe their experience of wearing a bra and not wearing one. Some people only wear them in certain situations (like playing sports), while other people have chosen to never wear them at all. His first findings were that if you don’t wear a bra, your nipples stay an average of 7 mm higher per year. The reason? Not wearing one strengthens your breasts. For some of the study’s volunteers, playing sports without a bra wasn’t a problem. Nor was going to work, being at home, or attending a party without one. Their breasts didn’t hurt at the end of the day, and they didn’t feel any pressure or discomfort. See also: 10 breast cancer warning signs The only “downside” that they mentioned was the reactions of people around them. They said people looked at them funny or simply told them to put on one. In those cases, the participants chose to wear a wireless bra to avoid uncomfortable stares or comments. At the same time, this study might have left out a large portion of the female population: women over 30 years old, women with large breasts, overweight women, and women who have had children. Everything can change if even one of these conditions is met. During pregnancy, for example, the breasts grow and the mammary glands move downward. In these cases, it’s often considered a good idea to wear a bra. Fact and fiction when it comes to wearing a bra While you might think that women have always worn bras, that’s not the case. It’s a very modern invention that really became popular as a fashion trend. Let’s take a look at 6 of the most common myths and realities about wearing bras: “Wearing a bra is necessary” Again, we have to refer to Professor Rouillon here to respond to this one. According to him, a bra can cause stretch marks, flaccidity, and a loss of firmness in the breast tissue. Therefore, they are actually a “false necessity.” “You need them to fight the effects of gravity” We don’t know what Isaac Newton would say about it, but most women think that wearing a bra can help prevent breasts from starting to sag or slow down the process. While this seems to be a law in the female world, the truth is that bras can actually limit the growth of tissue that supports the breasts. Because of that, it doesn’t provide any anatomical or physiological benefits. “Bras with an underwire are better” Excessive use of bras with underwire can cause injuries – both internal and external. They have even been associated with an increased risk of breast cancer. “You should also wear a bra at night” Some women don’t take off their bras at night because they’re worried about the effects of gravity or because they think that wearing one will make it more comfortable to sleep on their stomachs. The first is a myth and the second is more about personal habits or beliefs. According to the American Society of Plastic and Reconstructive Surgeons, there are microscopic ligaments that hold the breasts in place. When they become “used” to having something else do the work for them (i.e., the bra), they weaken, which often causes a loss of firmness. “The bigger the breasts, the tighter the straps” Before considering what kind of adjustment you need, it’s best to purchase a bra type that has straps relative to the size and weight of your bust. If you have large breasts, the straps need to be wider (and the opposite for women with smaller breasts). You also have to remember that the more tension there is in the straps, the less work your ligaments do. When you take off your tight bra, your breasts will sag more than usual. It turns them into something like an elastic band that was released after being stretched for hours. We recommend you read: 5 reasons why breasts hurt “You need extra support for exercise and during pregnancy” This can be completely true, because while you’re exercising, and during pregnancy, your breasts grow (or swell) more than usual. Of course, you should wear a special kind of bra and always remember to take it off at night or after a sweaty workout. Other circumstances that might involve greater support include: - Being overweight. - Having large breasts in proportion to your body size. - Breastfeeding or having gone through menopause. Finally, you shouldn’t wear a bra for more than seven or eight hours straight. You can wear it while you’re at work or away from home, and take it off when you get back home. This way, your breasts relax and you reduce the risks related to wearing a bra. Lastly, like we said, take it off before you go to sleep! It might interest you...

Što nauka kaže - je li pametno stalno nositi grudnjak? Nošenje grudnjaka je ne samo normalno nego i gotovo obavezno pa se većina žena osjeća nago ako slučajno izađe bez njega. No, je li nam on zapravo potreban, šteti li zdravlju ili, naprotiv, koristi? Ni stručnjaci nemaju jedinstven odgovor, a istraživanja koja su se bavila tom problematikom također su davala neusklađene rezultate. ZA Jedna od najčešćih teza u prilog nošenju grudnjaka jest da se grudi sastoje od masnog tkiva i nemaju mišića pa im grudnjaci osiguravaju učinkovitu potporu, što može spriječiti ili ublažiti obješenost grudi u kasnijoj dobi. Obješenost grudi, posebno ako su veće, može dovesti do natezanja kože vrata i brade koja se zbog stalne izloženosti stresu natezanja može i sama s vremenom objesiti, što se također može izbjeći nošenjem grudnjaka. Od lošeg držanja do bolova u leđima Nošenje grudnjaka može pomoći i u održavanju pravilne posture (držanja tijela), što je vrlo važno, ne samo za lijep izgled, nego i za zdravlje. Osim toga, žene s velikim grudima mogu imati jake bolove u leđima ako ne nose grudnjak, a ti bolovi također mogu dovesti do nepravilnog držanja tijela, koje je najčešće pognuto prema naprijed. Naime, grudnjak može u određenoj mjeri preoblikovati figuru, ispraviti male nedostatke, poput ovješenosti, vrlo malih ili vrlo velikih grudi, te cijelu figuru učiniti privlačnijom i skladnijom. Kod žena s izuzetno velikim grudima grudnjak pomaže zadržati grudi na mjestu gdje bi trebale biti (umjesto da budu spuštene gotovo do struka), što stvara dojam da su manje i čvršće. Nošenje grudnjaka može pomoći i ženama s vrlo malim grudima da stvore iluziju punoće i veličine, što im omogućuje da se osjećaju zadovoljnije i sigurnije u sebe. Potpora smanjuje bol i neugodu Treba istaknuti i da nošenje grudnjaka sprečava neugodno i ponekad bolno udaranje dojki jedne o drugu (ako su većih dimenzija) pri hodanju i kretanju, kao i trenje između grudi i kože ispod njih te posljedično prekomjerno znojenje koje čak može izazvati gljivičnu infekciju u području neposredno ispod grudi. To je posebno važno ljeti na visokim temperaturama kad je znojenje pojačano, ali i pri bavljenju sportskim aktivnostima. Naime, vježbanje bez ikakve potpore grudima može izazvati bol i neugodu i dovesti do istezanja kože i ligamenata, a to opet vodi onome što niti jedna žena ne želi - obješenim grudima. PROTIV Petnaestogodišnje istraživanje o učinku nošenja grudnjaka na izgled i zdravlje grudi, provedeno na Sveučilištu Besançon u Francuskoj pod vodstvom prof. Jean-Denisa Rouillona, pokazalo je da od njegova nošenja nema nikakve koristi. U medicinskom, psihološkom i anatomskom smislu sprečavanje izloženosti dojki sili teži ne rezultira nikakvim pozitivnim učincima. Štoviše, isto istraživanje je otkrilo da je upravo suprotno od uvriježenog mišljenja, odnosno da nenošenje grudnjaka čini grudi čvršćima. Razvijaju se mišići Naime, nenošenje grudnjaka dugoročno dovodi do razvijanja veće količine mišićnog tkiva koje osigurava prirodnu potporu grudima, a zahvaljujući tome grudi bez grudnjaka izgledaju čvršće i podignutije, čak i veće. S druge strane, "potpora" koju grudnjak osigurava dojkama slabi mišiće u području grudi, a to dovodi do brže obješenosti dojki. Znanstvenici su opovrgnuli teze da nošenje grudnjaka uzrokuje rak, ali su dokazali da ometa kvalitetan noćni san zbog pritiska tkanine, žice i kopče na kožu. Nošenje grudnjaka ima još jednu negativnu posljedicu, a to je da stalno stezanje i pritisak ometaju i usporavaju cirkulaciju u području grudi. Bolno stezanje može, uz to, izazvati i druge neugodne probleme, kao što su otežano disanje, bol u području prsnog koša. Pritišće limfe i krvne žile Grudnjak, osobito ako nije odgovarajuće veličine, može stezati i pritiskati limfne putove, a to može dovesti do nakupljanja otrovnih i otpadnih tvari u tkivu, koje bi se inače izlučile iz tijela. Također, kad su krvne žile pritisnute i stegnute, smanjen je i dovod kisika i nutrijenata u stanice cijelog tijela. Jedno istraživanje provedeno u Sveučilišnoj bolnici u Walesu pokazalo je da grudnjaci povećavaju rizik za pojavu neugodne boli u grudima, kao i za pojavu cista. I za kraj, još jedno istraživanje čiji rezultati ne idu u prilog grudnjacima objavljeno je u stručnom časopisu The Journal of Biological and Medical Rhythm Research, i pokazalo je da nošenje grudnjaka dovodi do povećanja tjelesne temperature i smanjenja lučenja melatonina za čak 60 posto, a melatonin je ključan hormon kako za regulaciju sna, tako i za usporavanje procesa starenja te pravilno funkcioniranje obrambenog sustava.
