No soap, no water, no nothing. If you don't shower regularly, that's your prerogative (though there's no guarantees your friends and family won't have something to say).

But beyond personal preference, there's actually a science behind what happens to your body when you don't routinely bathe.

This popular video delves into some of the physical effects that washing too little (or too often) has on your body.


1. Your skin needs good bacteria

Up to 1,000 species of bacteria live on your skin, along with 80 types of fungus, the video explains. But most of these germs are actually good for us—they work to push out the “bad” bacteria or break down skin secretions to produce natural moisturizers.

Bathing is our second line of defense against some of the nastier bacteria, so if you don’t regularly bathe and then touch your mouth, nose or eyes, you’re exposing yourself to harmful germs that could get you sick.

2. You can get skin infections

In line with point number one, that balance of “good” and “bad” bacteria on our skin can be upset by not washing enough. If you don’t wash your body, it makes it easier for germs that cause actual skin infections to flourish.

3. Some skin conditions are exacerbated

“If you didn’t wash at all, dirt, sweat, dead skin cells and oil would start to accumulate,” the video explains. Not bathing is also harmful for people who have chronic skin conditions like acne. “Not bathing could make it worse.”

4. You develop crusts of dirt on your skin

Dermatitis neglecta is a skin condition characterized by patches of thick, brown plaques that occur when you don’t bathe for a very long time, according to the National Institute of Health (NIH). They are made up of different things like sweat and bacteria, and form a compact crust of dirt on a localized area of skin. Yikes.

5. You smell

Contrary to popular belief, it’s not actually sweat itself that smells, the video explains. Sweat itself is actually odorless. It’s B.O., also known as bromhidrosis, that stinks. It happens when bacteria feed on the proteins and fatty acids in sweat, and then convert them into bad smelling chemicals.

How often should you shower?

Don’t bathe too often, though. You don’t want to strip your body of the natural chemicals it needs to stay healthy. Watch the full video to find out how often dermatologists say you should bathe.

Drones are firing seed pods to plant forests — and it’s actually working

Technology is the single greatest contributor to climate change but it may also soon be used to offset the damage we’ve done to our planet since the Industrial Age began. In September 2018, a project in Myanmar used drones to fire “seed missiles” into remote areas of the country where trees were not growing. Less than a year later, thousands of those seed missiles have sprouted into 20-inch mangrove saplings that could literally be a case study in how technology can be used to innovate our way out of the climate change crisis.

“We now have a case confirmed of what species we can plant and in what conditions,” Irina Fedorenko, co-founder of Biocarbon Engineering, told Fast Company. “We are now ready to scale up our planting and replicate this success.”

The Himalayas on a clear day.

The towering Himalayas may seem unshakable, but deep beneath them, the Earth is shifting in ways scientists never expected.

The world’s most dangerous tectonic secret might lie under the Himalayas

The Himalayas, one of the most awe-inspiring mountain ranges on Earth, have long captured the imaginations of adventurers and scientists alike. Towering above the clouds, these colossal peaks hold not only breathtaking beauty but also crucial geological secrets. Recent research suggests something astonishing: the Indian tectonic plate—the very foundation of the Himalayas—may be splitting in two deep beneath the surface.

For millions of years, the Indian Plate has been pushing northward, colliding with the Eurasian Plate and giving rise to the Himalayas. But new findings from Stanford University geologist Simon L. Klemperer and his team indicate that this seemingly solid landmass is undergoing a dramatic transformation, one that could have significant implications for earthquakes and mountain stability in the region.

A sea otter floating in a kelp bed.

Sea otters have come to the rescue on the coast of one California town.

Otters are wiping out all the crabs. Scientists say it’s saving the coast.

It is an established scientific fact that otters are adorable. They hold hands with fellow otters as they drift atop the water and use rocks to playfully crack open clams. Hermione's patronus is a sea otter! They're also voracious eaters, consuming about a quarter of their body weight daily. That last bit led them to become ecological superheroes in one California coastal town.

At Elkhorn Slough in California, a thriving population of southern sea otters has taken on an unlikely role: invasive species exterminators. According to USA Today, the otters’ voracious appetite for European green crabs, one of the West Coast’s most destructive invasive species, has nearly wiped the crabs out in the estuary. This has helped revive a delicate ecosystem that had been struggling for decades.

European green crabs, originally from Europe as you might have guessed, arrived on the West Coast in the 1980s and quickly became a menace. Though small—just four inches across—they wreak havoc on coastal ecosystems by devouring seagrass, baby crabs, and salmon while competing with native species. They’ve also caused significant damage to multimillion-dollar shellfish industries for Dungeness and king crabs.

Dogs know when you're lying, and they're not ok with it.

Your dog knows when you’re lying, and they’re quietly judging you for it

Your dog isn't just watching your every move—they're judging them, too. According to research by Akiko Takaoka of Kyoto University , dogs are a lot better at reading human behavior than we give them credit for. In fact, they know when you're lying. And worse? They remember it.

The experiment that exposed canine trust issues

In a clever experiment involving 34 eager and unsuspecting pups, Takaoka and her team put canine social smarts to the test. The setup was simple: most dogs will follow a human’s point to find food. So, first, researchers pointed to containers with treats. The dogs eagerly trotted over, rewarded with snacks and tail wags.

He died 3 times and came back with the same message: love is the only thing that matters

Dannion Brinkley has been clinically dead three times, but each experience gave him the same stunning insight — love, intent, and service are what really matter. His story invites us to see death not as an end, but a profound transformation.

Most people don't come back after death. Dannion Brinkley has done it three times — and what he brought back has changed lives.
