Hacks4Wellness was created from a genuine passion for health, longevity, nutrition, exercise, and biohacking. As a woman in my forties, I’ve spent more than a decade exploring ways to improve my own health, from the fundamentals of nutrition, movement, and sleep to emerging research and new wellness technologies.
With a background in Public Health and certification as a Nutrition Coach, I combine what I’ve learned through education and research with my own real-world experiences and experiments.
Hacks4Wellness is where I share what I discover along the way, with one goal: to help make healthier living and longevity more practical, understandable, and achievable.
Contact
Hacks4Wellness wouldn’t be what it is without its readers and community. If you have a question, an idea for something you’d like me to explore, feedback on the site, or simply want to say hello, I’d love to hear from you.
Hacks4Wellness.com is a science-backed wellness platform founded in 2024, created for women 40+ who want to take control of their health, slow the aging process, and feel stronger than ever. This is not a generic health blog. It is a personal project built on years of research, real-life experimentation, and a genuine passion for longevity.
The site covers everything from nutrition and fitness to biohacking, sleep optimization and supplements. All content is rooted in evidence-based research and personal experience. Think of it as following a friend who happens to have a background in public health, a certification in nutrition coaching, and an obsession with living well.
My Story
My name is Kajsa Martensson. I am a woman in my forties, living in northern Europe, with a biological age of 29. That number is not a coincidence. It is the result of years of studying, testing and applying the best longevity strategies I could find.
I hold a bachelor’s degree in Public Health and have completed the Food Matters Nutrition Certification Program, which deepened my expertise in holistic and functional nutrition. With over 15 years of absorbing health research through studies, podcasts and books, my interest in this field runs deep.
Alongside my health journey, I am an internet entrepreneur with over a decade of experience building successful online businesses. My most successful company was sold for over 4.5 million USD in 2017. I now bring that same dedication and drive to Hacks4Wellness.
Outside of work, you will find me playing tennis or golf, lifting weights, running, or spending time with my family.
My Mission
I started this site because I wanted to share what actually works. Too much of the practical advice we receive about health and nutrition is influenced by big food and pharmaceutical industries. I wanted to offer an alternative voice, one that is honest, personal and grounded in real science.
If I can inspire even one person to make a small change that leads to a healthier, longer life, this platform has done its job. Health is contagious. One person changes, influences another, and the ripple effect begins.

Your muscles do SO much more than make you look strong! 💪❤️
And for women going through perimenopause and menopause, building and maintaining muscle becomes more important than ever.
As estrogen levels decline, we gradually lose some of its protective effects on our bones, muscles and metabolism. Bone loss can accelerate, increasing the risk of osteoporosis, while maintaining muscle mass becomes more challenging.
But here’s the empowering part: You can do something about it!
Strength training helps preserve muscle, strengthen bones, improve insulin sensitivity and support your long-term health.
And combined with adequate protein, it’s one of the most powerful investments you can make in your future self.
Don’t just train for how you want to look today. Train for the life you want to live at 70, 80 and beyond. ❤️
💬 Are you strength training? If so, how many hours per week? I’d love to know!
💪 Want to take your training and recovery routine to the next level? I’ve recently discovered DoNotAge’s new Performance sachet, combining creatine, Nitralis® and NAC in one convenient daily drink.
Comment PERFORMANCE and I’ll send you the details! ❤️

What if some of the simplest things you do could have surprisingly powerful effects on your health? ❤️
We often think improving our health requires intense workouts, complicated routines or hours at the gym.
But your body has some pretty incredible mechanisms built right in!
From activating your body’s ”second heart” to supporting bone strength, blood sugar regulation and brain-body coordination, small movements can do more than you might expect.
And the best part? Most of them take less than a minute and require little to no equipment! ✌️
💬 Which of these five surprised you the most?

Your future isn’t built in one day. It’s built by what you do every day. ❤️
We often think that changing our lives requires big decisions, dramatic transformations or extraordinary motivation.
But when it comes to health, happiness and longevity, it’s usually the small, repeated actions that shape who we become.
The morning walk. The strength training session. The nutritious meal. The decision to prioritize sleep. The moments we choose to slow down and take care of ourselves.
Healthy aging isn’t about doing everything perfectly. It’s about creating habits that support the life you want to live, year after year.
And I think that’s incredibly empowering. Because while we can’t control everything about our future, we can influence so much through the choices we make today. 🌿
💬 What’s one daily habit you believe your future self will thank you for?
One of my own daily habits is supplementation, and I’ve found a simple way to make it effortless to stay consistent.
💬 Comment EASY and I’ll share the convenient supplement routine I’ve incorporated into my day

Something interesting happens when you start prioritizing your health. ❤️
You don’t just become stronger or fitter. Your standards for how you treat yourself begin to change.
You start protecting your sleep, choosing foods that make you feel good, setting boundaries and moving your body because you appreciate what it can do.
And perhaps most importantly, you stop accepting things that no longer serve your physical and mental wellbeing.
Healthy aging isn’t just about adding years to your life. It’s about creating a life you feel good living. 🌿
And that starts with the small choices you make every day.
💬 Have you noticed your standards changing as you’ve become healthier? What’s one thing you no longer tolerate?

What if one of the most powerful things you could do for your longevity was simply WALK MORE? 🚶♀️❤️
For decades, we’ve been told to aim for 10,000 steps a day. But did you know that the famous 10,000-step goal actually originated from a Japanese marketing campaign, not scientific research?
Now, a major 2025 study published in The Lancet suggests that 7,000 daily steps may be a sweet spot for healthy aging, with impressive benefits for longevity, brain health, cardiovascular health and more.
And here’s the best part: You don’t need expensive equipment, a gym membership or a complicated routine.
Just a pair of comfortable shoes and the willingness to keep moving. 🌿
Every step counts. 👣
💬 How many steps do you take on an average day? My personal goal is still set at 10,000 😊
📩 Want more science-backed longevity tips? Comment EMAIL and I’ll send you my FREE Longevity eBook, packed with valuable tips on how to age well and stay healthy for longer ❤️

Your 40s aren’t about slowing down. They’re about getting smarter with your health! 💪❤️
As we age, our bodies change, and so should some of our habits.
Building muscle, prioritizing protein, supporting recovery and nourishing our bodies become increasingly important for our metabolism, energy and long-term health.
But healthy aging isn’t about doing everything perfectly. It’s about making small, intentional changes that add up over time. 🌿
And remember, it’s never too late to start!
💬 Is there a healthy habit swap you’ve made that you’re particularly proud of? I’d love to hear!

For thousands of years, our ancestors lived in close connection with nature. They walked barefoot, breathed fresh air, moved across natural landscapes, swam in rivers and oceans, and lived by the rhythms of the sun.
Yet today, we spend most of our time surrounded by walls, screens and artificial light.
Wild animals don’t belong in captivity. And neither do we. 🌍💚
Our bodies are still deeply connected to the natural world. And science continues to uncover fascinating ways that spending time in nature can support our physical and mental health, from reducing stress and supporting immune function to improving sleep and overall wellbeing.
Nature isn’t just somewhere we go to escape everyday life. It’s something we’re biologically connected to.
And perhaps reconnecting with it is one of the simplest things we can do for our health and longevity. ❤️
