The Longest Mile: December 2025
In this edition of The Longest Mile, we’ll share why the holidays are the perfect time to lock in and build momentum for the year ahead, the wellness travel trends we’re watching, an easy take on one of the hottest biohacking trends of the year—peptides and a few updates from Mellow Mile.
December always sneaks up fast. One minute it feels like fall, and the next the year is almost over. Everyone starts talking about new goals and fresh starts, but December is really the month to lay the groundwork for the next year. It’s also a time to challenge yourself.
With the holiday parties in full swing and all kinds of tempting sweets around, December becomes a test. It’s the month where you decide not to have that cookie, or skip the nightcap before bed. We think those small decisions make all the difference. They prepare your mind and body for the New Year. When you stack small wins during the hardest and most tempting moments, your New Year’s resolutions become much easier to achieve.
On another note, we’ve seen a huge wave of interest around health and wellness this year. It feels like America is finally making a shift toward better overall health. Major food companies have started changing outdated and harmful ingredient lists, and more people are actually reading labels for the first time.
Another trend we’ve noticed is the boom in health and wellness travel. People are flying all over the world for “medical tourism” to get tests done that often cost much more in the U.S. Personally, I wouldn’t want to use vacation days getting MRIs, bloodwork, and lab tests.
What does interest me and what’s growing fast is wellness tourism.
Wellness tourism is booming. The total addressable market is already in the trillions and is expected to keep growing. These trips aren’t filled with doctor visits or the hum of medical machines. It’s the opposite.
In places like Austria, wellness isn’t flashy or extreme. It’s slow, structured, and designed to help your nervous system calm down while your body recovers. Most retreats blend medical insight, nature, and old European spa culture.
One of the biggest pillars is thermal bathing and sauna culture. You move through hot saunas, steam rooms, and mineral pools in a set order. Heat opens the body, improves circulation, and helps muscles relax. Cold plunges or cool air reset the nervous system. The benefits include lower stress, better sleep, reduced inflammation, and a deep sense of calm that can last for hours.
Another core piece is guided walking and light movement. This isn’t hard training. It’s slow hikes through alpine trails, lakeside walks, and posture-focused movement. Being outside at altitude improves oxygen use, clears your head, and gently improves cardiovascular health without stressing your body. Many people notice clearer thinking and steadier energy within just a few days.
Digestive reset and nutrition support are also central. Meals are simple, smaller, and intentionally timed. Food is high quality and easy to digest, often paired with mindful eating and proper chewing. The benefits are reduced bloating, better gut health, improved nutrient absorption, and more stable energy throughout the day.
Many retreats also include light medical check-ins and diagnostics. This can include bloodwork, metabolic testing, sleep assessments, or gut analysis. These insights help guide your stay and give clarity, instead of guessing or following trends or subjecting your body to unnecessary ionizing radiation.
Sleep optimization is taken seriously. Early nights, dark rooms, no screens, magnesium or mineral support, and quiet environments help reset your circadian rhythm. After just a few nights, many people report the deepest sleep they’ve had in years.
The reason people are flocking to Austria is simple. They don’t come home exhausted. They come home regulated. Calmer. Clearer. More connected to their body. It’s not about escaping life. It’s about remembering how life is supposed to feel.
Of course, wellness retreats aren’t cheap. Even those in the U.S. can be just as expensive. Because of that, many people are looking for more affordable options. One trend that’s been around for a while but has made a resurgence is peptides, and more specifically BPC-157.
BPC-157 stands for Body Protection Compound-157. It’s a small peptide that comes from a protein found naturally in human stomach acid. People are interested in it for its role in healing and repair, especially in the gut and connective tissue.
One reason people are drawn to BPC-157 is its ability to increase blood flow to injured tissue and support the formation of new blood vessels. Better blood flow means better delivery of oxygen and nutrients, which can speed up recovery. It also appears to protect the gut lining, which is why people with digestive issues often mention it.
Common reasons people consider BPC-157 include recovering from tendon or ligament injuries, dealing with nagging joint pain, healing gut irritation, or supporting recovery during high training volume. Some people also report reduced inflammation and faster healing from strains or overuse injuries.
That said, BPC-157 is not FDA-approved for medical use in humans. Most strong evidence comes from animal studies, not large human trials.
Our honest take is that BPC-157 can make sense if someone has a clear issue they’re trying to fix like a stubborn injury or gut irritation and they already have the basics locked in. It makes much less sense as something to “optimize” an already stressed body.
If the environment is wrong, sleep is poor, and stress is high, no peptide will fix that. But when the foundation is solid, tools like BPC-157 can sometimes help the body do what it already wants to do: heal.
We are not medical professionals and are only sharing personal opinions. I personally deal with arthritis in my shoulder from two surgeries, and it’s something I’ve been considering. I haven’t tried it yet, but plan to in the future.
As we close out the year, we want to reflect. This year was big for Mellow Mile. After two years of work, we finally launched in November. We’re grateful for every order, every message, and every person choosing cleaner basics.
As we grow through 2026, we plan to host our first small pop-up so people can see, feel, and understand what non-toxic clothing really means. We’re also testing new non-toxic products for next year, all with the same focus on comfort, quality, and clean materials
