We’ve all been there—staring at a screen, heart racing over an email that shouldn't be that scary, while our bodies react like we’re being chased by a literal lion. It’s a bit ridiculous when we think about it, but our nervous systems don't always get the memo that a "deadline" isn't a death threat. When the stress hits, we need a way to tell our bodies to simmer down that actually works.
At Flewd Stresscare, we’re big fans of the "soak it off" philosophy, but we’re not talking about basic bubbles and a candle. We’re talking about functional bathing that uses the chemistry of the water to help our bodies reset. One of the most underrated ways to do this is through transdermal soaking.
This article is gonna break down why this specific combination is so effective for everything from itchy skin to fried nerves. We’ll look at the science of transdermal absorption (that’s just a fancy way of saying "getting nutrients through our skin"), why magnesium chloride hexahydrate beats the pants off regular epsom salt soaks, and how to mix the perfect bath to find some actual relief. We believe that stresscare should be simple, science-backed, and slightly indulgent.
Can't decide? You don't have to! Give all four soaks a try with the soak stan favorite, the Stresscare Sampler 12-pack.

When we talk about a baking soda magnesium bath, we're really talking about a two-pronged approach to wellness. We’re addressing the external environment (the water and our skin) and the internal environment (our mineral levels and nervous system). It isn't just about "detoxing," which is a word that gets thrown around way too much in wellness circles. It’s about replenishment and stabilization.
Baking soda, or sodium bicarbonate, is a household staple for a reason. In the bath, it performs a few key tasks. First, it acts as a water softener. If we live in an area with hard water, the minerals in that water can actually be quite drying or irritating to our skin. Baking soda helps neutralize that, and the same kind of approach shows up in our healing bath soak recipe.
Perhaps more importantly, baking soda is alkaline. Most of the irritants our skin deals with daily are acidic, and our skin’s natural barrier (the acid mantle) can get thrown out of whack by stress, sweat, and environmental pollutants. A soak with baking soda can help soothe the skin and reduce irritation from things like eczema, psoriasis, or even a pesky yeast infection. It also helps neutralize chlorine, which is found in most municipal tap water and can be incredibly drying to our skin and hair.
Most people reach for a bag of epsom salt when they want a magnesium bath. Epsom salt is magnesium sulfate. While it’s fine for a basic soak, we prefer our magnesium chloride hexahydrate guide. Why? Because it’s the most bioavailable form of magnesium for transdermal absorption.
Bioavailability is just a measure of how easily our bodies can actually use what we’re giving them. Magnesium chloride is more easily recognized and absorbed by our skin than the sulfate version. When we soak in it, the magnesium bypasses our digestive system—which is great because taking high doses of magnesium orally can sometimes lead to an emergency trip to the bathroom. By going through the skin, the magnesium can get straight to work supporting over 300 biochemical reactions in our bodies, including the ones that regulate our stress response and muscle relaxation.
Key Takeaway: Baking soda neutralizes the water and soothes the skin, while magnesium chloride provides a superior, highly absorbable way to replenish the body’s most important anti-stress mineral.
When we put these two together, we're creating a powerhouse environment for recovery. It’s like a reset button for our largest organ—the skin—and our entire nervous system. Here is how we see the benefits playing out in real-time.
Our skin is often the first place stress shows up. Whether it’s a flare-up of a chronic condition or just general itchiness and dryness, stress-induced cortisol spikes can wreak havoc on our skin barrier. The baking soda helps to gently cleanse and soothe, while the magnesium helps support skin hydration and cellular repair. Many of us find that a baking soda magnesium bath leaves our skin feeling sooooo soft without the need for heavy lotions afterward. If you want the bigger-picture breakdown, see magnesium soak benefits.
It’s particularly helpful for:
We tend to carry our stress in our shoulders, jaws, and backs. That physical tension is often a sign that our magnesium levels are running low. When we’re stressed, our bodies burn through magnesium at an accelerated rate. If we don’t replace it, our muscles stay in a state of contraction.
A warm bath with magnesium chloride helps those muscle fibers finally let go. For that kind of soreness, Ache Erasing Soak is the one we reach for.
This is where the magic really happens. Magnesium is often called the "chill-out mineral." It helps regulate neurotransmitters that send signals throughout our brain and nervous system. Anxiety Destroying Soak pairs that magnesium base with zinc and a B-vitamin complex to help stabilize the mood even further.
When we combine the mineral support of magnesium with the skin-soothing properties of baking soda, we’re sending a loud, clear signal to our brain that it’s safe to relax. It’s a shift from the "fight or flight" sympathetic nervous system to the "rest and digest" parasympathetic nervous system.
We don't need a PhD to mix a good bath, but there are a few tips that can make the experience much more effective. If we’re gonna do it, we might as well do it right.
The biggest mistake we see people make is making the water too hot. We get it—a steaming hot bath feels great for a second, but it can actually be a stressor for the body. If the water is too hot, our heart rate climbs, and we might feel dizzy when we get out.
The sweet spot is between 92°F and 100°F. This is warm enough to open our pores and relax our muscles without sending our bodies into a heat-induced panic. As for timing, we want to aim for at least 15 to 20 minutes. This gives the minerals enough time to actually move through the skin barrier. If we have the time, 30 minutes is even better.
If we're DIY-ing it, a standard ratio for a regular-sized tub looks like this:
However, if we want something that’s been scientifically formulated to target specific symptoms, our stress-relief soaks take this foundation and add targeted vitamins and nootropics. For example, if we’re feeling particularly frazzled, our Anxiety Destroying Soak uses that magnesium base but adds zinc and a B-vitamin complex to help stabilize the mood even further.
Next Steps for a Better Soak:
- Keep the water warm, not scalding.
- Soak for a minimum of 15 minutes to allow for mineral absorption.
- Hydrate with a big glass of water before and after the bath.
- Don't rinse off immediately—let those minerals stay on the skin.
To get the most out of our baking soda magnesium bath, we should treat it like a ritual rather than just another thing on the to-do list. Self-care shouldn't feel like a chore; it should feel like a relief.
Before we even turn on the faucet, we like to do a little bit of dry brushing. This helps shed dead skin cells and stimulates lymphatic flow, which makes our skin even more receptive to the nutrients in the bath. It also just feels really good.
We also recommend turning down the lights. Our brains are constantly bombarded by blue light from our phones and overhead LEDs. Giving our eyes a break helps signal to the pineal gland that it’s time to start thinking about sleep and relaxation.
When we get out of the tub, we should do so slowly. Our blood vessels have dilated from the warmth, which can lead to a slight drop in blood pressure. We like to pat our skin dry rather than rubbing it vigorously. This leaves a thin layer of the mineral-rich water on our skin to continue absorbing.
If we’re using something like our Ache Erasing Soak, which includes vitamins C and D along with omega-3s, we want those nutrients to hang out on our skin for as long as possible. There’s no need to rinse off unless we’ve used a lot of heavy oils that feel sticky. Usually, the baking soda and magnesium leave the skin feeling clean and smooth.
We have to be real here: a single bath isn't going to fix a high-stress lifestyle or cure a medical condition. However, it is a incredibly effective tool for managing the daily toll that stress takes on our bodies. Think of it like charging a phone. We wouldn't expect our phone to stay at 100% forever after one charge, right? We have to plug it in regularly.
Consistency is where the real transformation happens. Taking a baking soda magnesium bath once or twice a week helps keep our magnesium levels topped up and our skin pH balanced. Many of our 100,000+ happy customers report that the effects of a single Sads Smashing soak can last up to five days, but building a routine is what really changes the game. We're in control of how we respond to stress, and choosing to nourish our bodies is a powerful move.
The combination of baking soda and magnesium is more than just a DIY trend; it’s a functional way to support our bodies in a world that never seems to stop. By softening the water, balancing our skin’s pH, and providing the most bioavailable form of magnesium, we’re giving our nervous systems the tools they need to actually relax.
"Stress is inevitable, but staying stressed is a choice. We choose to soak it off."
If we’re ready to take our bath game to the next level, we can skip the measuring cups and try one of our targeted formulas. Whether it's the Insomnia Ending Soak for better sleep or the Sads Smashing Soak for a mood boost, we've built every packet to deliver the maximum nutrient punch through the skin. Give your body what it’s been missing and see how much better "calm" can feel.
While we can use Epsom salt, it is magnesium sulfate, which isn't as easily absorbed by the skin as magnesium chloride. For the best results and the highest bioavailability, we recommend using magnesium chloride hexahydrate flakes.
Generally, yes, as baking soda is very soothing and can help balance skin pH. However, we always recommend testing a small patch of skin first or starting with a smaller amount of baking soda if we know our skin is particularly reactive.
For general stress maintenance, once or twice a week is a great goal. During periods of high stress, muscle soreness, or skin flare-ups, we might find that soaking three times a week provides the support we need to stay balanced.
There's no need to rinse off! In fact, letting the minerals dry on the skin allows for continued absorption. If the skin feels slightly tingly or itchy (which can sometimes happen if magnesium levels are very low), a quick rinse with plain water is fine.
