We've all been there. It’s 2:00 AM, and we’re staring at the ceiling, mentally cataloging every awkward thing we said in 2014 while our brain runs a marathon. We’ve tried the white noise machines, the blackout curtains, and the "sleepy" teas that just make us have to pee at 4:00 AM. When we search for a "this works bath soak," we’re usually looking for one of two things: either the specific "Deep Sleep" brand or a solution that actually, finally, definitely works to shut our brains off.
At Flewd Stresscare, we started our journey in 2020 because we realized that most bath products are just expensive, scented water. We were tired of being told that a glittery bath bomb would fix a nervous system fried by endless emails and global chaos. We wanted something that actually addressed the physiological roots of our stress.
In this guide, we're gonna break down the science of what makes a bath soak effective, why the form of magnesium we choose is the most important decision we’ll make, and how we can turn a quick 15-minute soak into a legitimate tool for better rest. We’ll explore the difference between basic salts and transdermal nutrient treatments so we can finally get the sleep we deserve. Relief is achievable; we just need the right chemistry to get there.
Can't decide? You don't have to! Give all four soaks a try with the soak stan favorite, the Stresscare Sampler 12-pack.

The search for a bath soak that "works" is a search for a physiological reset button. Our bodies treat a stressful work deadline or a difficult conversation exactly the same way they’d treat a predator in the wild. Our nervous systems don't know the difference between a lion and a "per my last email" notification. We end up stuck in a state of high cortisol and sympathetic nervous system dominance, which is a fancy way of saying we’re "wired but tired."
When we look for products like the This Works bath soak, we’re often drawn to ingredients like lavender, vetiver, and camomile. While aromatherapy is great for signaling to our brain that it's time to chill, it’s often not enough to address the physical depletion that stress causes. Chronic stress literally sucks the nutrients out of us—specifically magnesium.
Most of us are walking around with magnesium levels that are lower than they should be. This is a problem because magnesium is responsible for over 300 biochemical reactions in our bodies, including the ones that help our muscles relax and our brains produce melatonin. If we’re low on the good stuff, no amount of lavender-scented air is going to make our bodies feel safe enough to fall into a deep sleep. We need a soak that does more than smell nice; we need one that replenishes what stress has stolen.
When we look at the ingredients in a high-end soak, the first thing we usually see is salt. But not all salts are created equal. Many popular soaks use sea salt (Maris sal) or Epsom salt. While these aren't "bad," they aren't the most efficient way to get magnesium into our systems.
Sea salt is mostly sodium chloride. It’s great for skin exfoliation and making us feel like we’re at a spa, but it doesn't do much for our internal stress levels. On the other hand, magnesium sulfate—better known as Epsom salt—has been the gold standard for decades. However, our bodies have to work harder to break down sulfate to get to the magnesium.
This is why we focus on magnesium chloride hexahydrate. It’s the most bioavailable form of magnesium for transdermal absorption. "Bioavailable" just means our bodies can actually use it easily and quickly. "Transdermal" means it goes through our skin. When we soak in magnesium chloride, we’re bypassing the digestive system entirely, which is a massive win for those of us with sensitive stomachs.
Key Takeaway: For a bath soak to actually "work" for stress and sleep, the type of magnesium matters more than the fragrance. Magnesium chloride hexahydrate is the top choice for fast, effective absorption.
It’s worth doing a deep dive into why we prefer magnesium chloride over the traditional Epsom salts we find in the grocery store. It comes down to molecular structure and solubility.
We often think of a bath as a looooong luxury, but with the right form of magnesium, we only need 15 to 30 minutes to see a difference. We aren't just sitting in salty water; we’re essentially giving our nervous systems a nutrient-dense "infusion" that helps pull us out of fight-or-flight mode.
Why don’t we just take a magnesium pill and call it a day? We could, but oral magnesium supplements often come with a literal "run" of side effects. Because magnesium is a natural muscle relaxant, it also relaxes the muscles in our digestive tract. If we take too much at once, we end up spending more time in the bathroom than in bed.
By using a transdermal approach—absorbing nutrients through the skin—we skip the gut entirely. This allows us to use higher concentrations of magnesium without the digestive drama. When we soak in a warm (not hot) bath, our pores open up, and the magnesium ions can move into our bloodstream.
This method is particularly helpful when we’re dealing with "tired-wired" symptoms. When our bodies are physically replenished with magnesium, we may find that our heart rates slow down and our muscles stop feeling like they’re tied in knots. It’s a direct delivery system to the parts of us that need it most.
What to do next:
A soak that really works shouldn't stop at magnesium. Stress is a complex beast, and different types of stress require different nutritional support. For example, if we’re dealing with the kind of stress that keeps us awake at night, our needs are different than if we’re dealing with physical muscle aches.
In our Insomnia Ending bath soak, we don't just throw in some salt and call it a day. We include vitamins A and E, along with L-carnitine. We also use a yuzu scent because it’s bright and calming without being cloying.
Nootropics are substances that can support cognitive function. When we use them in a bath soak, they work alongside the magnesium to help calm the mental chatter.
When we combine these with magnesium chloride, we’re creating a "nutrient treatment" rather than just a bath. We’re targeting the specific symptoms of our stress, whether that’s anxiety, rage, or that deep, heavy sadness that sometimes hits after a long week.
We know that "self-care" often feels like just another chore on our to-do list. But a bath soak only works if we actually get in the tub. The goal isn't to create a three-hour ritual with candles and silence (unless that’s your thing). The goal is consistency.
We recommend a 15 to 20-minute soak at least two to three times a week. This helps keep our magnesium levels stable rather than waiting until we’re in a full-blown stress crisis to try and fix it.
Key Takeaway: Consistency is the secret sauce. Regular 15-minute soaks build up our body's resilience to stress over time.
If we’re looking at the market, we’ll see a lot of products claiming to help us sleep. The This Works brand is famous for their Deep Sleep line. Their soak uses a blend of lavender, vetivert, and wild camomile. It’s a beautiful product, especially if we’re sensitive to scents and want that classic "spa" aroma.
However, if we compare the ingredient lists, we’ll see that many traditional soaks rely heavily on sea salt and fragrance. Flewd is built differently. We position ourselves as an Epsom salt replacement and a step above the standard bath bomb. We’re focusing on the "Stresscare" aspect—meaning we want to fix the underlying nutrient deficiency that makes us feel so frazzled in the first place.
While a lavender bath is lovely, a magnesium chloride soak fortified with B-vitamins, zinc, or potassium (depending on the formula) is doing the heavy lifting for our nervous systems. We aren't just masking the feeling of stress; we’re helping our bodies process it.
We have to be real: no bath soak is a magic wand. If we have a major medical condition or chronic, clinical insomnia, a soak is a supportive tool, not a cure. We always recommend talking to a healthcare professional if sleep or anxiety issues are interfering with our ability to function.
That said, many of our 100,000+ customers report that they feel a significant shift after just one soak. The "heavy" feeling in our limbs, the racing thoughts, and the physical tension in our shoulders often start to dissipate while we’re still in the water.
Results can vary, but the science of magnesium absorption is solid. By replenishing our minerals, we’re giving our bodies the building blocks they need to regulate themselves. It's about taking control of our physiological state rather than just letting stress run the show.
One of the reasons we created different formulas at Flewd is because stress isn't a monolith. We don't all experience it the same way.
By matching our soak to our specific mood, we ensure that we’re getting the right nutrients for what we’re going through right now.
Quick Summary of Benefits:
Finding a bath soak that actually works comes down to looking past the packaging and checking the chemistry. While aromatherapy is a great addition, the heavy lifting is done by bioavailable minerals like magnesium chloride hexahydrate. By bypassing the gut and delivering nutrients directly through the skin, we can support our nervous systems and help our bodies transition into a state of rest.
"We don't have to just 'deal' with being stressed. We can actively replenish what stress takes away, one soak at a time."

Many people find that soaking in magnesium, especially magnesium chloride, helps support relaxation and better sleep quality. It works by helping the body regulate neurotransmitters that quiet the nervous system and supporting the production of melatonin. While it’s not a cure for clinical sleep disorders, it’s a powerful tool for managing the "wired" feeling caused by daily stress.
Because magnesium chloride is highly bioavailable and retained well by the body, many users report feeling the relaxing effects for up to five days. For the best results, we recommend a consistent routine of two to three soaks per week to keep nutrient levels stable. This cumulative effect helps build our long-term resilience to stress.
Yes, in terms of absorption and efficiency, magnesium chloride is generally considered superior to magnesium sulfate (Epsom salt). It’s more easily absorbed through the skin and is less likely to cause skin dryness or irritation. Magnesium chloride also has a broader range of benefits for the nervous system and skin barrier health.
Our formulas are 99% natural, non-toxic, and free from common irritants like parabens and phthalates. However, we always recommend checking the ingredient list if we have specific allergies. We even offer fragrance-free versions of our soaks for those of us who are extra sensitive to scents but still want the nutrient benefits.
