1There’s a new study that shows that black bras may be harmful to your health. The study showed that women who wore black bras on a regular basis were 25% more likely to develop breast cancer than those who didn’t. It found that it is the dye in the black fabric, rather than the actual fabric itself, which is the possible culprit. For all you ladies out there — we’ve got some great news for you! You can look great AND feel healthy AND stay safe from developing breast cancer with this article!

1. Research has shown that black bras may increase your risk for breast cancer.

Wearing a bra 24/7 may actually be harmful for your breasts. A study published in the journal Environmental Health Perspectives found that women who wore their bras more than 12 hours a day had a 75% increased risk of breast cancer compared to those who wore them less than 12 hours a day.The research team analyzed the daily habits of 10,259 women who were enrolled in the Avon Breast Cancer Prevention Study between 1990 and 1994 and followed up with them between 2004 and 2008. They discovered that women who wore their bras more than eight hours a day, nearly every day, were twice as likely to develop breast cancer compared to those who wore their bras for under eight hours. Additionally, women wearing their bras for more than eight hours a day had a six-times increased risk of developing ovarian cancer. The top reason for wearing your bras for so long was because they looked pretty. The other requested reasons were comfort, franchise sizes, or because it was the only fashion item they had.

Another study published in 2012 in the peer-reviewed journal Breast Cancer Research and Treatment found that women who desired to wear their bras for support during or after exercise showed an increased average of 25% increase in breast density and a five-fold increase in the relative risk of developing breast cancer.

Overall, wear your bra for support, but don’t wear it for every movement. If you stay in your natural eating habits and work out regularly, you might be doing yourself a favor by avoiding the boob job.

Swimmers and runners know that cardio equipment can be bulky, especially those that are not as breathable as sports bras. Think about how you like to breathe while you’re exercising. Does your breath seem fuller when you’re wearing support garments or are you forced to take more shallow breaths? More frequent lapses in concentration could mean overworking your brain.

The scientific verdict here is clear: Waterproof sports bras could be a potential public health risk.

2. The study found that it is the dye in the fabric, not the fabric itself, which may cause cancer.

For years, there has been a debate about whether red or blue clothing is most likely to cause cancer. A study that was recently published in the Journal of the National Cancer Institute found that it is the dye in the fabric, not the fabric itself, which may cause cancer. Red dye is made with aniline, which is a possible carcinogen.

What makes the new study unusual is that the study followed women for 21 years and found that black bras were significantly more effective at preventing cancer than white bras. The explanation? The mild smell associated with black clothing.


The new study studied 727 postmenopausal women who were part of the National Cancer Prevention Study from 1994–2008. During that time period, 873 of the women developed or died from breast cancer. In the 21 years studied, 819 of the women wore red clothing; 365 wore blue clothing; and 568 wore black clothing (although this last group only included those women who were close to retiring).

At the start of the study, the women were asked about their clothing habits and their breast cancer risk. Information about the cancer risk factors such as smoking, estrogen, oral contraceptives and menopause was collected at the beginning of the study. Then every 5 years, women were asked about how they dressed during the previous year. Afterwards, the women were assessed for breast cancer risk factors such as parity, breastfeeding, exercise, family history of cancer and use of estrogen, oral contraceptives and menopause preventative services (PPSSs). Women who wore black bras were 25% less likely to develop breast cancer than those who wore white bras.

Dr. Carolyn Ford of the University of Texas Health Science Center notes, “[The study] addressed the breast issues in women long considered marginalized and marginalized.”


So how do the women who wore black bras feel about their study results? Some are thanking the clothes for their longevity and cancer prevention; and some are shocked by the results.

3. Here are a few tips to help you look great and stay healthy!

To look great and stay healthy, here are a few tips: 1) Get enough sleep. Sleep is an important part of staying healthy because it helps your body recover and repair itself. Getting enough sleep will help you go throughout the day with more energy and help you look more attractive. 2) Eat more vegetables.Vegetables are great sources of nutrients like fiber and water, which are both good for you. Eating a greater variety of vegetables can help you fill up on nutrients your body needs. Note: 100 g of fresh broccoli provides roughly 330 calories, 15 grams of fiber, 20 grams of protein, and 5 grams of folate (which supports a healthy immune system and nervous system.) 3) Wear supportive clothing. Supportive clothing helps you move better and utilize muscle fibers while you’re at rest. Women should wear items that offer support so they can get the most practical result out of their workouts. Women who wore supportive clothing had a lower risk of breast cancer. 4) Play with yourself! We all have our different goals, such as looking a specific weight — we’re human, aren’t we? Being more self-aware can help you achieve your goals and feel more confident.

Conclusion: Always buy bras in natural fabrics like cotton, silk, or wool to avoid dye-related health issues. And remember — your health is more important than what color your bra is!

Remember, your health is more important than what color your bra is! So make sure you’re wearing bras made from natural fabrics like cotton, silk, or wool. When you wash your bras, make sure you double rinse them to make sure all the dye is removed and that you wash your bras in a separate load from your other laundry.

One more thing before we move onto our favorite workout apparel — I’ve recently found that my favorite sweatpants are trouble. I know that’s kinda cruel of me, considering that they’re actually made of cotton, but hear me out. Black sweatpants (they’re known as “fireman jeans” in Japan) can increase your risk of developing breathing issues, according to Healthline. That’s because the fabric of the sweatpants contains certain dyes that can create electrical charges that can cause short circuits in your lungs.

Because this is starting to get a bit messy — do yourself a favor and choose cotton colors like gray, or shades of gray. There’s one last thing I want to talk about with sweatpants, and that’s when you’re working out and your sleeves are rolled up like a hoodie. Well, you should get something with a hoodie pattern because the dyes in the knit draw the specific kinds of airwaves that could potentially damage your lungs.

JK, I’m kidding about the hoodie, but you get the idea. Every time I see someone else in a sweatpants or sweatsuit combo and they’re doing burpees or American Ninja Warrior, I think to myself, “No wonder they’re good at burpees!” It’s because sweatpants do a great job covering up all the ways our clothes can inadvertently attract harmful pollutants. As a result, if you’re doing work-out or exercise-related activities and your clothes aren’t colorful, we strongly encourage you to change them.
