We’ve all been there. It’s 6:00 PM, the laptop is finally closed, but our brains are still vibrating with the phantom echoes of notification pings. Our bodies aren’t exactly fans of the modern world; they tend to treat a spicy email exactly the same way they’d treat a predator in the wild. It’s a little bit ridiculous, but the stress is very real. When we’re feeling that collective burnout, the siren call of a warm bath is hard to ignore.
At Flewd Stresscare, we’ve spent years obsessing over what actually happens to our bodies when we soak. While a standard bath is nice, a targeted bath soak is a whole different level of recovery. We want to show us how to take a basic tub of water and turn it into a legitimate tool for nervous system maintenance. This guide covers everything from the basic chemistry of salts to the specific additives that help us tackle everything from muscle aches to a bad mood. We’re gonna look at why certain ingredients work, how to mix them at home, and when it’s time to level up our routine.
Can't decide? You don't have to! Give all four soaks a try with the soak stan favorite, the Stresscare Sampler 12-pack.

There’s a reason "bath time" has transitioned from a childhood chore to a cornerstone of adult survival. It’s one of the few places where we can’t be reached by a screen. But beyond the quiet, the science of bathing—specifically mineral bathing—is what really matters for our stress levels.
When we talk about how to make bath soak, we’re usually looking for two things: skin softening and mineral replenishment. Most of us are walking around with significant nutrient deficiencies because stress literally eats through our internal supply of things like magnesium and B vitamins. By adding specific elements to our bath water, we’re using our largest organ—the skin—to help get those levels back to where they belong.
The DIY approach is great because it lets us control exactly what goes into the water. No weird synthetic fragrances, no "mystery" dyes, and no massive price markups for fancy packaging. We can customize the scent to our mood and the mineral content to our physical needs. Plus, there’s something oddly satisfying about playing "apothecary" in our own kitchens.
Every good bath soak starts with a base of salt. But not all salts are created equal, and they each serve a different purpose in our quest for relaxation.
Despite the name, Epsom salt isn’t actually salt. It’s magnesium sulfate. It’s been the gold standard for baths for decades because it’s cheap and widely available. When we dissolve it in warm water, it breaks down into magnesium and sulfate. Most of us use it because we’ve heard it helps with sore muscles, and while the clinical jury is still out on exactly how much magnesium sulfate our skin can actually absorb, the anecdotal evidence from millions of athletes and stressed-out parents is hard to ignore.
This is the "real" salt. Sea salt (including the trendy pink Himalayan variety) is packed with trace minerals like potassium, calcium, and iron. It’s great for creating a "buoyant" feeling in the water, which helps take the pressure off our joints. Pink Himalayan salt is particularly popular because it’s one of the purest forms of salt available, having been protected under layers of lava and ice for millions of years. It’s suuuuuper pretty in a jar, too.
If we want to get serious about minerals, Dead Sea salt is the heavy hitter. It has a much lower sodium content than regular sea salt and a much higher concentration of minerals like zinc and bromide. It’s often used by people looking to support skin health or manage flare-ups of dryness and irritation. It tastes incredibly bitter, so don’t get it in the mouth, but our skin will love it.
Key Takeaway: Start with a 2:1 ratio of Epsom salt to sea salt for a balanced base that addresses both muscle tension and skin mineral needs.
Once we have our salt base, we need a few more items to turn a simple soak into a treatment. These ingredients change the texture of the water and help our skin stay happy while we’re pruning up.
Sodium bicarbonate (good old baking soda) is a must-have. It helps neutralize the acidity of our skin and can help soothe the itchiness that comes with seasonal changes or irritation. It also makes the water feel silky, which is a nice sensory bonus. If we’re using essential oils, baking soda acts as a bit of a "carrier" to help them distribute rather than just floating on the surface in a big oil glob.
If we’re feeling fancy, adding a tablespoon of French green clay or Kaolin clay can help with a "detox" vibe. These clays are known for drawing out impurities. If our skin is feeling particularly dry, finely ground oatmeal (colloidal oatmeal) is a lifesaver. Just make sure it’s ground into a very fine powder, or we’ll end up with a tub that looks like a giant bowl of porridge.
If we want to hop out of the tub with skin that feels like a million bucks, we need oil. Jojoba, sweet almond, or fractionated coconut oil are all great choices. However, a word of caution: oil makes the tub slippery. We have to be careful getting out, and we’ll definitely have to give the tub a quick scrub afterward to prevent a "ring" from forming.
This is where most DIY bath soaks go wrong. Essential oils are powerful plant extracts, not just "perfume." Because they don’t dissolve in water, they can sit on the surface and cause skin irritation if we aren’t careful.
We should never just drop essential oils directly into the bath water. Instead, we should mix them into our salt or a carrier oil first. This ensures they’re diluted before they touch our skin.
Here is a foolproof way to assemble a batch of bath soak products that will last for about 5 to 10 baths.

Note: If we use baking soda, don’t seal the jar 100% tight if we live in a very humid area, as pressure can occasionally build up. A little air gap is fine.
At Flewd, we believe that stress isn't a monolith. Sometimes we’re "tired-wired," sometimes we’re just sore, and sometimes we’re actually angry at a spreadsheet. Our bath soak should reflect that.
When our brains won't shut up, we need a combination that leans heavily on relaxation, like Insomnia Ending Soak.
Physical stress needs a different approach. We want to increase blood flow and soothe inflammation, like Ache Erasing Bath Soak.
When we’re feeling low, we want bright, "happy" scents and minerals that support our mood, like Anxiety Destroying Bath Soak.
While DIY soaks are a fantastic entry point into self-care, there’s a limit to what Epsom salt (magnesium sulfate) can do. If we’re looking to actually move the needle on our internal nutrient levels, we have to talk about bioavailability—which is just a fancy way of saying how much of a substance our body can actually use.
Most store-bought salts and DIY recipes rely on magnesium sulfate. However, research suggests that transdermal absorption is the most bioavailable form of magnesium for the skin. It’s what we use in every Flewd Stresscare soak.
Magnesium chloride has a completely different molecular structure that allows it to bypass the digestive system (where a lot of magnesium gets lost or causes... let’s say, "tummy issues") and get straight to work. While we can certainly make a great soak at home with Epsom salt, switching to a magnesium chloride base is like moving from a standard sedan to a high-performance vehicle.
We also go a step further by including targeted nootropics and vitamins. For example, our Anxiety Destroying Soak includes Zinc and a B-vitamin complex, while our Insomnia Ending Soak uses Vitamins A and E alongside L-carnitine. DIY is fun for the vibes, but when we’re dealing with high-level stress, we often need a more clinical approach to nutrient delivery.
We’ve made the soak, the water is running, and the vibe is set. Now, we need to actually do it right. Bathing for stress relief is a skill, and we’re here to master it.
We often think "the hotter, the better," but that’s not actually true for stress relief. Water that is too hot can actually trigger a stress response in the body (the "fight or flight" reflex) because our internal temperature is rising too fast. We want the water to be "warm-hot"—comfortable enough to sit in for 20 minutes without sweating profusely.
The "sweet spot" for mineral absorption and muscle relaxation is 15 to 30 minutes. If we hop out after 5 minutes, we’ve basically just had a very inefficient shower. If we stay in for an hour, our skin starts to dehydrate. Aim for that 20-minute mark to let the nutrients really do their thing.
One of the biggest mistakes we make is immediately rinsing off after a mineral bath. Don't do it! We want those minerals to stay on our skin. Pat dry gently with a towel and let the remaining nutrients continue to absorb. This is also the perfect time to apply a moisturizer to "lock in" the hydration.
One bath is a treat. Three baths a week is a strategy. Our bodies respond best to consistency. When we regularly replenish our magnesium and mineral levels, we build up a "buffer" against the daily stressors that usually knock us sideways.
Before we start mixing, let’s talk about what not to do. We want our bath to be a sanctuary, not a source of more stress.
If we’re feeling overwhelmed by all the options, let’s keep it simple. We don't need a massive apothecary cabinet to start.
If we find that the DIY life is a bit too much work, or if we’re looking for a more intense nutrient hit, that’s exactly why we created the Stresscare Sampler 12-pack. Our packets are pre-measured, scientifically formulated, and designed to deliver specific results—whether that’s squashing rage or erasing insomnia.
Learning how to make bath soak is a small but powerful way to take back control from the chaos of the world. It reminds us that our physical well-being is worth 20 minutes of our time. Whether we’re mixing up a custom Himalayan salt blend or reaching for a pre-formulated Flewd soak, the act of intentional bathing is a massive win for our nervous systems.
Stress is inevitable, but staying stressed is a choice. We have the tools to replenish our bodies, calm our minds, and show up as the best versions of ourselves.
Our bodies go through a lot to keep us moving. The least we can do is give them a warm, nutrient-rich place to land at the end of the day.
While table salt is technically sodium chloride, it’s not the best choice for a bath. Table salt is usually highly refined and stripped of the trace minerals like potassium and magnesium that make sea salts beneficial for our skin. Plus, it often contains anti-caking agents that we don't necessarily want to soak in for 20 minutes.
If our recipe includes baking soda and we live in a humid environment, the soda can react with moisture in the air and create a tiny bit of gas. In a completely airtight glass jar, this pressure can build up over time. It’s rare, but it’s better to be safe and allow a little bit of airflow or just use a container that isn't 100% hermetically sealed.
If we keep it dry and don't add any liquid carrier oils, a salt soak can last for 6 to 12 months. If we do add carrier oils (like almond or jojoba oil), the shelf life drops to about 3 months, as those oils can eventually go rancid. Always give the jar a "sniff test" before hopping in the tub.
Yes, dried flowers like rose, lavender, and chamomile are generally safe and add a beautiful aesthetic to the experience. However, they can be a bit of a mess to clean up and might clog the drain. To avoid the hassle, we can put our bath soak into a reusable muslin bag or use a high-quality drain strainer to catch the botanicals before they disappear down the pipes.
