Social media has become a fertile breeding ground for conversations about hygiene. Whether it’s celebrities bragging about how little their family bathes, or battles over how often people should wash their sheets or bras, there’s no shortage of strong opinions.

One of the debates that gets the most diverse responses is how often people wash their denim jeans.

Denim atelier Benjamin Talley Smith tells TODAY that jeans should be washed “as little as possible, if at all.” Laundry expert Patric Richardson adds they should be cleaned “after nine or 10 wearings, like to me, that is the ideal.” At that point, they probably have stains and are “a little sweaty by that point, so you need to wash ’em,” Richardson says.

Still, some people wash and dry them after every wear while others will hand wash and never hang dry. With all these significant differences of opinion, there must be a correct answer somewhere, right?

What the former Levi’s CEO says about washing jeans

The former CEO of Levi Strauss, Chip Bergh, has stepped up to set the record straight on when and how to wash your jeans. He caused a stir in 2014 when he said he only washes his jeans once a year, but it was for environmental reasons more than hygiene.

He later clarified his thoughts in a blog post, “The Dirty Jean Manifesto” he posted to LinkedIn.

“I made this provocative statement because I believe strongly in what our brands stand for: quality, durability and lasting products made sustainably. I also said it because I believe we don’t need to wash jeans as often as most people think we do,” Bergh wrote.

“We learned that an average pair of jeans consumes roughly 3,500 liters of water — and that is after only two years of use, washing the jeans once a week,” Bergh wrote. “Nearly half of the total water consumption, or 1,600 liters, is the consumer throwing the jeans in the washing machine. That’s equivalent to 6,700 glasses of drinking water!”

To add to the problem, denim jeans are often manufactured in places where water is scarce, such as India, Pakistan, Mexico, China and parts of California.

CEO offers clarification on his comments

Bergh spoke with CNBC’s Christine Tan and clarified his thoughts on jean cleanliness.

“True denim heads, people that really love their denim, will tell you to never put your denim into a washing machine. So that’s what I do,” Bergh explained. “If I drop some curry on my jeans, I’m gonna clean it. But I’ll spot-clean it. And if they get really gross you know, if I’ve been out sweating or something and they get really gross, I’ll wash them in the shower.”

However, when Bergh washes his jeans in the shower, he does it while wearing them and washing them with soap. The image that the scene conjures is of a cowboy bathing in a cartoon, clothes on and all.

There are a lot of different opinions on how often one should wash and dry their jeans and many of them boil down to personal preference. But the debate on the topic has brought up one very big point we should all consider: when choosing how often we wash our jeans, a big part of the decision should be considering the amount of water we use.

A single door can open up a world of endless possibilities. For homeowners, the front door of their house is a  gateway to financial stability, job security, and better health. Yet for many, that door remains closed. Due to the rising costs of housing, 1 in 3 people around the world wake up without the security of safe, affordable housing. 

Since 1976, Habitat for Humanity has made it their mission to unlock and open the door to opportunity for families everywhere, and their efforts have paid off in a big way. Through their work over the past 50 years, more than 65 million people have gained access to new or improved housing, and the movement continues to gain momentum. Since 2011 alone, Habitat for Humanity has expanded access to affordable housing by a hundredfold. 

A world where everyone has access to a decent home is becoming a reality, but there’s still much to do. As they celebrate 50 years of building, Habitat for Humanity is inviting people of all backgrounds and talents to be part of what comes next through Let’s Open the Door, a global campaign that builds on this momentum and encourages people everywhere to help expand access to safe, affordable housing for those who need it most. Here’s how the foundation to a better world starts with housing, and how everyone can pitch in to make it happen. 

Globally, almost 3 billion people, including 1 in 6 U.S. families, struggle with high costs and other challenges related to housing. A crisis in itself, this also creates larger problems that affect families and communities in unexpected ways. People who lack affordable, stable housing are also more likely to experience financial hardship in other areas of their lives, since a larger share of their income often goes toward rent, utilities, and frequent moves. They are also more likely to experience health problems due to chronic stress or environmental factors, such as mold. Housing insecurity also goes hand-in-hand with unstable employment, since people may need to move further from their jobs or switch jobs altogether to offset the cost of housing. 

Affordable homeownership creates a stable foundation for families to thrive, reducing stress and increasing the likelihood for good health and stable employment. Habitat for Humanity builds and repairs homes with individual families, but it also strengthens entire communities as well. The MicroBuild® Initiative, for example, strengthens communities by increasing access to  loans for low-income families seeking to build or repair their homes. Habitat ReStore locations provide affordable appliances and building materials to local communities, in addition to creating job and volunteer opportunities that support neighborhood growth. 

Everyone can play a part in the fight for housing equity and the pursuit of a better world. Over the past 50 years, Habitat for Humanity has become a leader in global housing thanks to an engaged network of volunteers—but you don’t need to be skilled with a hammer to make a meaningful impact. Building an equitable future means calling on a wide range of people and talents.Here’s how you can get involved in the global housing movement:

Speaking up on social media about the growing housing crisis 

Volunteering on a Habitat for Humanity build in your local community

Travel and build with Habitat in the U.S. or  in one of 60   countries where we work around the globe

Every action, big and small, drives a global movement toward a better future. A safe home unlocks opportunity for families and communities alike, but it’s volunteers and other supporters, working together with a shared vision, who can open the door for everyone.

Generation X (those born between 1965-1980) grew up eating classic Americana meals. During the 1970s, comfort meals like tuna casserole and salmon roquettes were popular meals.

Gen X also grew up eating some pretty unhinged (but all the more yummy) sandwiches. These meals are steeped in childhood nostalgia.

And to this day, Gen Xers are........
