Some wellness trends can look like the golden ticket to feeling better. Cold plunges. Intermittent fasting. Breathwork marathons. They fill your feed with promises of more energy, mental clarity, and superhuman resilience. But here’s the hard truth: if you’re deep in burnout, anxious before you even open your eyes, or constantly in survival mode, these trends might not be helping your nervous system. In fact, they might be making things worse.

Before we dive in, I want to make something clear. I love wellness. I love trying new things. But wellness is not one-size-fits-all. And it certainly isn’t always nervous-system informed. Many trends elevate stress in the body—on purpose. The idea is that controlled stress builds resilience. And sometimes, it does. But if you’re already living at the edge of your capacity, your system can’t always tell the difference between “good” stress and “bad” stress. It just registers threat. That’s where things start to break down.

Your nervous system has a window of tolerance. Inside that window, you function well. You communicate clearly, digest food properly, access creativity, and recover from stress. But when you pile on too many demands—even “healthy” ones—you can slip out of that window and into dysregulation. Instead of regulating your system, these trends can push you into anxiety (hyperarousal) or exhaustion and shutdown (hypoarousal).

Let’s look at three of the most popular wellness practices through a nervous system lens and explore what to consider before jumping in.

1. Intermittent Fasting

Intermittent fasting has earned its reputation for enhancing insulin sensitivity, supporting metabolic repair, and promoting autophagy. For some, it boosts clarity and energy. But fasting is also a stressor. It activates the HPA axis, raising cortisol and adrenaline. That might be fine if your system is well-regulated. But if you’re already depleted, skipping breakfast may intensify symptoms like brain fog, anxiety, and irritability.

When it helps:

• Your cortisol rhythm is balanced.
• You sleep well, digest well, and have stable energy.
• You’re not in an emotionally or physically demanding season.

When it hurts:

• You wake up anxious or wired.
• You’re exhausted but can’t rest.
• You’re in burnout, postpartum, high stress, or trauma recovery.

A gentler alternative? Eat a protein-rich breakfast within 60–90 minutes of waking. This regulates your cortisol curve, stabilizes blood sugar, and signals safety to your nervous system.

2. Cold Plunges and Ice Baths

Cold therapy is the darling of the wellness world right now. It’s celebrated for boosting dopamine, lowering inflammation, and building mental grit. But plunging your body into icy water triggers an intense sympathetic response—tightened blood vessels, a racing heart, and an adrenaline surge. Again, great if you have capacity. But for many women in chronic stress, it adds fuel to the fire.

When it helps:

• You’re regulated, grounded, and use cold to expand your window of tolerance.
• You follow the plunge with breathwork and warmth.

When it hurts:

• You already wake up feeling overstimulated or shaky.
• You’re in a trauma recovery or chronic freeze response.
• You use cold exposure to override exhaustion rather than honor it.

Try this instead: end your warm shower with 30 seconds of cold water while breathing slowly and deeply. It offers some of the same benefits without overwhelming your system.

3. Intense Breathwork (like Holotropic or Circular Breathing)

Breathwork can absolutely help regulate your nervous system. But certain types—especially those that use rapid, repetitive breathing patterns—can quickly become dysregulating. Fast breathing lowers CO2 levels in the blood, constricting vessels and reducing oxygen to the brain. This can cause lightheadedness, panic, or dissociation—particularly if you already struggle with anxiety or trauma.

When it helps:

• You’re grounded and ready to process stored emotion.
• You’re supported by a trained facilitator and clear on your capacity.

When it hurts:

• You enter the practice already activated.
• You’ve had panic attacks or struggle to stay present in your body.

A safer route? Start with down-regulating practices like the physiological sigh (two quick inhales through the nose, one long exhale through the mouth), or 4:7:8 breathing. These calm your system without destabilizing it.

The Bottom Line

Wellness trends can absolutely support healing—but only if they meet your body where it is. What helps one person regulate might keep another person stuck in dysregulation. The key is to pay attention to how you feel after the practice. Do you feel grounded? Energized in a sustainable way? Or do you feel more anxious, depleted, or numb?

Your nervous system isn’t looking for the next best hack. It’s looking for safety. And your job is to listen.

So instead of chasing every trending routine, ask yourself:

• What state am I in today?
• Does this practice help me feel more regulated or more frazzled?
• Is my body asking for stimulation, or is it asking for restoration?

Nervous system care isn’t about proving how disciplined you are. It’s about practicing discernment. And when you choose what supports your healing—instead of what looks impressive on Instagram—that’s when real transformation begins.
