In my clinical experience, when patients reduce their overall “total chemical load”—and take actions to reduce glyphosate exposure—they consistently feel and function better.

Choose organic when possible, especially for foods you eat often like oats and wheat products.
Prioritize your daily staples if budget is tight.
Wash and scrub produce thoroughly.
Avoid glyphosate-based weedkillers at home.

Unfortunately you can’t control federal policy or how fast it changes. So focus on what you can control: lower your exposure wherever possible and support farmers who are already using better practices.

Purposefully stressing out your body could be the secret to living longer. Sounds counterintuitive, right?

I’m not talking about chronic stress that overwhelms the body’s coping mechanisms and becomes detrimental to health over time. I’m talking about small amounts of stress that help build up your body’s stress defenses in a positive way. This is called hormesis, an intentional process aimed at promoting resilience.

The concept of hormesis suggests that exposing yourself to short bursts of healthy stress can actually activate your body’s built in longevity pathways and slow down the aging process.

From intense exercise to cold showers or sauna sessions, these practices may be tapping into ancient biological mechanisms that prime your cells for survival.

Exercise exemplifies how, through hormesis, low doses of stress improve your resilience and trigger beneficial systemic responses that fortify your health and extend your healthspan over the long term. And the data on exercise for optimizing healthspan and lifespan is overwhelming.

While you can’t exercise your way out of a bad diet, you can’t be healthy without exercise.

Our bodies were designed to move and that movement triggers all our longevity and health pathways. It’s the most powerful drug on the planet along with food.

Ever feel a surge of anxiety over something as simple as sending a “no” email?

That’s your nervous system doing what it learned to do to stay safe.

I sat down with .holistic.psychologist to discuss how so much of what drives anxiety, people-pleasing, overachieving, and relationship patterns lives in the BODY, in the automatic wiring of your stress response, not just in your thoughts.

We unpack how childhood experiences, including the ones you’ve minimized as “not that bad,” shape your nervous system, your relationships, and even your long-term physical health.

When your nervous system is stuck in survival mode, it shapes your biology, your boundaries, your relationships, and your capacity for joy. But you can rewire what you inherited, and what you learned.

Your sign to get some sun 👆🏼☀️

Getting sunlight before 10 a.m. can help reset your circadian rhythm and improve sleep quality.

Your circadian rhythm is your internal clock. It helps decide when you feel alert and when you feel sleepy. That clock is highly sensitive to light, especially in the morning.

In a large population study published in BMC Public Health, adults who got more sunlight before 10 a.m. had an earlier sleep midpoint. The sleep midpoint is the halfway point between when you fall asleep and when you wake up. It’s one way researchers measure sleep timing, which simply means when your sleep happens on the clock.

Aim for 20 to 30 minutes of natural light before 10 a.m. Step outside with your coffee. Take a short walk. Sit in direct daylight if you can. Morning light is one of the strongest signals your brain uses to set your daily rhythm.

Small changes in light exposure can influence when your body feels ready for sleep at night and alert in the morning.

You can be doing all the right things, but if you’re living in a constant stress response, stuck in fight or flight, your body isn’t getting the safety it needs to repair and replenish.

This was a moment in my conversation with .holistic.psychologist that really stayed with me.

We explored how profoundly the nervous system shapes our biology. When your system is wired for danger, it diverts energy toward protection, leaving repair, recovery, and growth as secondary priorities.

Chronic stress reshapes digestion, immunity, hormones, and cellular resilience. Safety is what allows the body to shift out of survival mode and into restoration.

My conversation with Dr. Nicole LePera goes live this Wednesday, 2/25. I can’t wait for you to hear this one. 🎧

A recent review found that radish greens (the leafy tops most people discard) contain higher concentrations of polyphenols and flavonoids than the radish root itself. 🫜🫜

These compounds act as antioxidants and cellular signaling molecules. Many of them travel to the colon, where gut microbes metabolize them into smaller bioactive compounds that can influence inflammation, metabolic pathways, and gut barrier function.

If you buy radishes with the tops attached, sauté the greens in olive oil, blend them into pesto, or stir them into soup at the end of cooking. Smaller leaves are more tender. Larger ones are better cooked.

Your microbiome responds to diversity, sometimes that starts with simply not throwing part of the plant away.

Struggling with gut issues? I put together a quick 4 question guide to help you find the SIBO Recovery Protocol and supplement stack that best matches your symptoms, so you can start healing with confidence. Drop a YES below, and I’ll DM it to you.

Dr. Robert Hedaya shares the story of a patient with severe panic attacks that ultimately traced back to a hidden biological issue, highlighting why psychiatry must look beyond the brain and consider the whole body.

Dr. Robert Hedaya explains how therapies like hyperbaric oxygen, neurofeedback, and targeted laser treatment aim to enhance the brain’s natural repair mechanisms, and how these approaches are expanding what’s possible in psychiatry.
