The Brief

This story was originally published on August 24, 2023 and has been updated to include a rerun of the podcast episode.

There is a moment of awe that washes over you when you step into a forest. Century-old trees tower above, sunlight twinkling through them. Birds tweet. Spiders weave their elaborate webs. The smell of pine needles fill the air.

The act of spending time in the forest is what the Japanese call shinrin-yoku, a term originating in the 1980s that means "bathing in the forest atmosphere," says Qing Li, a researcher on this topic and a professor at Nippon Medical School in Tokyo. "This is not exercise or hiking or jogging," he writes in his 2018 book Forest Bathing: How Trees Can Help You Find Health and Happiness. "It is simply being in nature, connecting with it through our sense of sight, hearing, taste, smell and touch."

Not only is "forest bathing" a magical way to explore nature, decades of research has shown that it's good for your health. It can boost your immune system, lower blood pressure and help with depression. It can also reduce the stress hormones cortisol and adrenaline and turn down the dial on your body's fight-or-flight response.

Li and Gary Evans, director of the Forest Bathing Institute in the U.K., talk to Life Kit about the science behind forest bathing and how you can reap these health benefits.

1. Find a location where you're surrounded by trees

The ideal place to forest bathe is well, in a forest. But if you live far away from one or don't have the means to get there, any place that has a lot of trees and quiet spaces will do.

"You can also get beneficial effects from a city park," says Li, but they won't be as significant as walking in the deep woods. A 2022 study published in the International Journal of Environmental Research and Public Health found that walking in a forest park had a greater impact on cardiovascular function than doing so in an urban park.

Walking in an urban park still has health benefits. Another study published in 2022 found that it can significantly improve mood and reduce stress, compared to walking in an urban gray setting.

2. Set aside a good chunk of time

To reap the ultimate rewards of shinrin-yoku, plan to spend two to six hours in the woods, says Li.

His research showed that forest bathing for about that amount of time helped boost immunity. One study found that participants who walked in the forest for two hours in the morning and two hours in the afternoon saw an increase in anti-cancer proteins and immune cells that kill tumors, with the effects lasting for at least seven days after.

If you can't set aside a good part of your day to meander through the forest, you can also do shorter walks. But the health benefits won't be as significant, says Li. "The longer [the time in the forest], the better. The longer has more effect."

A 2019 study published in the International Journal of Environmental Research and Public Health found that walking just 15 minutes through the woods can help relieve stress and anxiety.

3. Aim to reduce heart rate

Your forest bathing session is a good time to sit or walk or do some gentle yoga or tai chi. It's not the time to squeeze in your hardcore cardio for the week.

"The difference between normal activities and forest bathing is that we're going to move very slowly," says Evans. Forest bathing is about calming down your nervous system and reducing your heart rate and blood pressure.

If you exert yourself too much physically, your "tiredness will reduce the effect of forest bathing," says Li. Your body will produce more stress hormones such as adrenaline, noradrenaline and cortisol, which studies have shown that forest bathing can help decrease.

4. Breath in the scents of the forest

Many of the benefits of shinrin-yoku come when we inhale the chemicals that trees release into the air, called phytoncides, says Li. They can reduce our stress hormones and increase our levels of white-blood cells known as natural killer cells, according to his research.

In one study from 2009, his team ordered special concentrated essential oils made from Japanese cypress trees and then pumped them into the hotel rooms of test subjects using a diffuser. The people staying in those rooms saw about 40 to 50% of the health benefits as those who did a forest bathing session.

As a side note, if you can't make it to a forest, Dr. Li says you could get some of the benefits by diffusing tree-based essential oils at home.

5. Bolster your forest bath with meditation

When you get to the forest or the park, walk a little bit and then find a spot that speaks to you. That could be a clearing in the woods surrounded by a bunch of tall trees or a spot where a tree has grown into a curved shape that looks suspiciously like a seat. If it feels beautiful and resonant to you, that's what matters.

Now sit down, says Evans, and try this exercise. "Inhale for a count of one, two and then exhale for double the length of time, so it's one, two, three, four. Then keep that going."

"When the exhale is slower than the inhale, it sends a physiological message to your body that says: 'I'm safe. I can relax. It's OK,' " he adds.

This particular breathing exercise has been shown to have benefits on its own outside of the forest environment. The reason to do it in the forest is to allow yourself to relax so you can begin to notice all the sounds, colors and textures that nature has to offer.

You may be surprised by what you discover, says Evans. "Depending on what's happening in your emotional world, quite often when we look at nature or the forest, it sends something back to us to help us make sense of what's going on in our life."

State regulators voted Thursday to stop Southern California Gas Co. from charging customers to help pay for planning miles of pipelines that would bring hydrogen gas to the L.A. Basin.

The company says the project would reduce the region’s reliance on methane gas.

Southern California Gas estimates it would cost about $266 million to study and plan the project — called Angeles Link — and asked the state Public Utilities Commission to allow it to recover those costs through customer rates. The company had proposed a monthly increase of $0.35 on the average residential customer bill over the course of three years.

The commission unanimously rejected the request, saying the company had not proved any direct benefit to customers. The decision effectively halts the project for now, and comes amid a stall in federal funding for hydrogen projects under the Trump administration.

Local environmental groups involved in the community advisory process had also grown frustrated by negotiations that they said, in a letter to state regulators, “does not prioritize genuine community engagement.”

As global pollution levels continue to climb, the commission’s decision also highlights the growing challenge of transitioning to a cleaner energy supply amid rising utility bills and open questions about the safety and true environmental cost of largely untested technology.

Why hydrogen?

Hydrogen is a colorless gas that is considered "clean" because it doesn’t involve carbon, which — when burned to create energy — becomes carbon dioxide, a major planet-heating gas.

But it takes energy to produce hydrogen, and most hydrogen these days is created by burning fossil fuels. “Green” hydrogen is created by using clean energy sources like solar and wind to split water into oxygen and hydrogen.

SoCal Gas said the Angeles Link project would prioritize green hydrogen.

Most experts see green hydrogen as an important clean-burning fuel for hard-to-electrify industries, such as long-haul trucking and gas-fired power generation. The city of Los Angeles, for example, wants to retrofit its Scattergood Power Plant near El Segundo to burn hydrogen instead of methane gas to generate electricity.

There are many open questions about how safe the highly-combustible gas is for proposed uses and how much water it will require to make. At the same time, extracting and burning fossil fuels for electricity and fuel also takes water — a growing problem as climate change drives longer and hotter droughts.

Experts say, if done right, hydrogen can reduce that water intake and not have a major impact on water supplies.

Also, burning hydrogen could actually worsen local, lung-damaging nitrogen-oxide air pollution, at least with the technology as it currently stands, according to energy researchers.

Reactions to the decision

SoCal Gas will now have to turn to shareholders or other sources of funding if the company wants to proceed. The company did not directly answer LAist’s questions about whether it would.

“We continue to believe that hydrogen—including clean renewable hydrogen—can help advance California’s energy and climate goals while supporting the long‑term affordability, security and reliability of energy service for customers,” SoCal Gas spokesperson Brian Haas wrote in an email to LAist.

Environmental groups celebrated the vote, while emphasizing they see green hydrogen playing a role in the state’s future.

“Residential customers should not subsidize speculative infrastructure for large industrial users,” said Michael Colvin, director of the California Energy Program at Environmental Defense Fund, in a statement.

“We look forward to working with regulators, utilities and large customers to build a credible, cost-effective strategy to cut climate pollution from sectors that are hardest to electrify,” the statement read.

Global events like the World Cup and the 2028 Olympics are sure to draw thousands of new visitors wanting to get to know Los Angeles.

When you take a bite of the lomo saltado burrito from Merka Saltao, a fast-casual Peruvian restaurant in Culver City, one of the first things you'll notice is the sauce.

The wok-fried chunks of steak, dressed in a soy-and-oyster sauce reduction spiked with vinegar, saturate the rice inside the tortilla, highlighting the sweet heat of ají amarillo mixed with the velvety texture of pinto beans.

It's a beautiful confluence of flavors. It is also, depending on who you ask, either a creative act of evolution or a betrayal of Peruvian culinary heritage.

Standing on business

The lomo saltado burrito at Merka Saltao wasn't exactly a calculated move. Lifelong friends Alonso Franco and Ignacio Barrios — who met in high school in Lima — came to Los Angeles to bring Peruvian food to the masses, first through a ghost kitchen concept they ran from 2021 to 2023. The burrito happened almost by accident: a member of their kitchen team brought in a tortilla one day, someone suggested wrapping the lomo saltado in it, they ate it, and within three days, it was on the menu.

The data from the ghost kitchen made the case for keeping it there. Franco and Barrios had launched with around 140 dishes — lomo saltado, ceviche, chicken dishes, the works. But the numbers kept pointing to the same thing: wherever lomo saltado appeared on the menu, in whatever form, burrito, bowl, salad, it was the winner.

(Ceviche, for all its cultural cachet, is raw fish with raw onion — a harder sell for a weekday lunch. Lomo saltado, Franco noted, is steak and fries — basically a hamburger.)

The backlash

The two friends made the leap to brick-and-mortar in August 2025, opening Merka Saltao in downtown Culver City. It's one of the more competitive dining corridors in L.A., the kind of block that can support a $16 wellness bowl and a craft beer bar in the same stretch, populated by Amazon employees on lunch breaks, families on weekend outings, and food-literate regulars who will absolutely have opinions about what goes in a burrito.

Those opinions arrived faster than Franco expected. Within the first week of opening, an influencer came in and posted about the restaurant — but instead of showing the full menu, the bowls, the chicha morada, the flexibility of the concept, they showed the burrito. Just the burrito.

The comments turned quickly. "No! Peruvians don't eat burritos. ¿Qué car—o es eso?" — roughly, "what the hell is this?" — wrote one commenter. Another said "Burritos? We don't eat burritos in 🇵🇪”. Franco describes sitting at his computer reading the pile-on, feeling something between anger and devastation. "There was a moment where I probably even cried," he said, "thinking, I've made a mistake." But then he looked at the numbers. 30,000 had seen the post…. And half the comments were in his defense.

He took the conversation to Reddit, posting to r/FoodLosAngeles asking the community directly: am I wrong for this? The response was overwhelming — hundreds of comments, almost entirely in his favor, and a surge of new customers walking through the door shortly after.

Fusion by default

This is Los Angeles, where many of the dishes that define the Southern California diet were born precisely from cultures colliding. Roy Choi built an empire on Korean tacos. Al pastor traces its technique to Lebanese immigrants who brought the vertical spit. The California roll, invented by Japanese chefs in Los Angeles in the 1960s, introduced an entire country to sushi. None of these dishes destroyed the traditions they borrowed from. If anything, they expanded their audience. And the lomo saltado burrito isn't exactly a novel concept in Southern California to begin with — everyone from Pablitos Tacos in North Hollywood to Le Hut in Santa Ana, run by 2025 James Beard Award-nominated chef Daniel Castillo, has featured their own version. Even Disney's California Adventure got in on it, serving a lomo saltado burrito out of the Studio Catering Co. food truck as recently as last year.

Franco would also point out that lomo saltado itself — the dish the purists are so eager to protect — is a product of Chinese immigrants bringing the wok and soy sauce to Peru roughly 300 years ago. "Peruvian is by default fusion," he told me. "So we have all the right to wrap it up in a burrito." What the online critics were really doing, whether they knew it or not, was defending a dish that was itself once considered inauthentic — and doing so in the name of authenticity.

Where things stand

Since the backlash, Franco says business has been mostly steady — breaking even, which for a concept that requires high volume at a low price point, he considers a good sign. The controversy changed things in ways he didn't expect: people started coming in specifically because of the story, not just the food. He began putting himself front and center in the brand, regularly making videos on social media about what it's like to run the business, occasionally poking fun at himself and the whole debate. When we visited during the weekday lunch rush, there was a steady line of people waiting to order, many stopping to talk with Franco directly.

In a way, he's answered the authenticity question not with an argument but with a presence — showing up, telling the story, letting the food speak. "Honoring my food, if that requires pairing lomo saltado with a salad or wrapping it in a tortilla, I have no problem," he said. "I'm not being less authentic. We are evolving in Peru anytime. I have to be authentic on the individual flavor and then be flexible to reach more people to discover our flavors."

The burrito, it turns out, was never the point. It was just the door.
