7 unknown facts about breasts forming a figure 8 when running

Core Tip: Many people are obsessed with women's beautiful breasts, but know very little about them. In recent years, there have been more and more scientific studies and investigations on breasts, and the mysterious veil of breasts has gradually been lifted.

1. Your breasts are getting bigger

A recent survey by a major lingerie retailer found that in just 20 years, the size of American women's underwear has continued to increase, equivalent to a 3-inch increase in bust circumference. Weight gain and breast augmentation are the two main reasons for bra size changes.

2. 70% of women are dissatisfied with their breasts

70% of women are dissatisfied with their breasts and wish their breasts could be firmer and their cleavage more prominent. On the contrary, most men think their lovers’ breasts are “beautiful.”

3. Your breasts form an "8" shape when you run

When women exercise, their breasts will sway with their bodies, and the movement trajectory is like an "8", with a range of motion of up to 8 inches (about 20.3 cm). Breast pain during exercise is very common, and one-third of runners experience breast pain during exercise. Experts say that it is best for women to wear a suitable sports bra that can support the breasts when exercising.

4. Most people's breasts are different

One breast is usually 1/5 cup size larger than the other, and the nipple color and even height are slightly different.

5. Breast augmentation ranks first among cosmetic surgeries

Breast augmentation surgery topped the list of cosmetic surgeries in 2012. Although the number of breast augmentation surgeries in the United States decreased by 7% in 2012 compared to 2011, there were still 286,000 people who underwent breast augmentation surgery.

6. Touching the breasts can give women an orgasm

The study found that 82% of women said that stimulating actions such as caressing their breasts can help arouse sexual desire. At the same time, some people say that breast stimulation can help them achieve orgasm pleasure.

7. Bras don’t have a long history

An American woman, Mary Phelps Jacobs, first patented the "backless bra" in 1914 and began mass-producing bras. But the bra designed by Ada Rosenthal and her husband William Rosenthal in New York, USA in the 1920s is the standard for bras today.
