Examining The Best Soak For Sore Muscles

We all know that after a long, hard day or a strenuous workout, relaxing in a nice, warm bath can be one of the best ways to soothe our aching body and help it to recover. What many people may not know though, is that there are things you can add to your bath, to get even more benefits out of it.

While common cosmetic bathing products often claim to be able to do this, adding various different salts or essential oils to your bath could not only help to soothe your muscles and bones, but could even encourage better recovery, helping you to repair any injuries much faster.

With such a huge range of options available though, how could you possibly know where to start? Well, in today’s article, we will be examining the best soak for sore muscles and going through a range of the best things you can add to your bath to keep your body pain free and healthy.

So, if you want to optimise your bathing routine and make suffering with muscle pains and minor injuries a thing of the past, this is the article for you.

How Do Soaks Help Sore Muscles?

Exactly how a soak will help to soothe sore muscles depends on both the ingredients used for the soak, as well as the type of soak it is. 

Many soaks work as they have the ability to help dilate the blood vessels throughout the body. This will improve circulation and allow more blood to flow towards the muscles that are sore, ensuring they have plenty of oxygen and nutrients to help them heal and ease the pain.

Another major benefit that comes with improved blood circulation is that it speeds up the removal of accumulated waste products like lactic acid in the tissue of the muscle. This can aid with speeding up recovery but only in cases where the muscles are sore due to strenuous physical activity. 

The soak may also be able to help relax the muscle tissues directly. This can help to reduce or even eliminate any stiffness or inflammation. This will lead to improvements in soreness, pain symptoms, mobility, and range of motion. 

Epsom Salts For Sore Muscles

Epsom salts are among the most popular ingredients for creating soaks and have been used around the globe for decades, as they are thought to be highly effectively, while being relatively affordable. 

The main component of Epsom salts is magnesium sulphate heptahydrate, a chemical also known simply as magnesium sulphate. Studies show that when the Epsom salts are added to the water, the salt breaks down into the two compounds, magnesium, and sulphate. 

In their base forms, each of these chemicals are able to enter the body much more easily than they can while they are combined. This helps to ensure that both of the chemicals are able to reach the muscle tissue quickly and efficiently, in order to effectively induce a state of maximum relaxation. 

To ensure Epsom salts are properly dissolved, it is widely recommended that you add the Epsom salts to your bath while the water is still running. This will allow the natural movement of the water to gently mix it in, breaking the salts down much more effectively.

The ideal dose of Epsom salts will depend on the size of your tub, the amount of water you use, and how sore your muscles are. That said, most adults using a standard size tub will want to use between 1 and 2 cups of Epsom salts to achieve maximum effects, without any risk of adverse reactions. 

Epsom Salts Vs Other Salts

The primary reason that Epsom salts became the preferred option to use in soaks was because they are cheap and readily available. This obviously makes them a popular choice for a wide range of people with all different budgets. 

Many people have also reported that Epsom salts not only dissolve faster but that the results they offer can be seen much earlier as well. This means they require much less prep time and can help to soothe your pain and soreness much faster

Then there is the fact that beyond just helping with sore muscles, Epsom salts are able to produce some other benefits that can be extremely helpful for a variety of the body’s other functions as well. 

Epsom salt soaks can help to reduce stress, improve relaxation, and even help some people to sleep better. This is ideal for improving your overall health, wellbeing, and quality of life, but is particularly beneficial for people trying to help their muscles heal and recover after a strenuous exercise session.

By speeding up recovery, the Epsom salts will help you to perform better during your next exercise session, while limiting the amount of rest time needed between the sessions themselves. This will improve workout consistency and dramatically improve the speed at which you achieve results. 

The magnesium sulphate content can even potentially help to improve the functions of the nerves throughout your body. This can be incredibly helpful for everything from improving your workouts to enhancing your ability to perform daily tasks as efficiently as possible.

Other Salts To Add To A Soak For Sore Muscles

Other popular salts you can add to a soak include dead sea salt, fleur de sel sea salt, Himalayan pink salt, and pure magnesium salt. These all work in the same basic way as Epsom salts, yet have wildly differing prices and chemical makeups from product to product.

While Epsom salts are the most well rounded, those looking for something a little more specific should weigh up their budget and the exact effect they are hoping to achieve with their soak and consider whether one of these salts may be a better option for them.

Essential Oils For Sore Muscles

There are certain essential oils that can also be used to effectively help to relax sore muscles and relieve the pain in them. These oils will generally be made from natural extracts and offer a safe yet effective remedy for a whole range of different aches, pains, health problems, and ailments. 

Peppermint Oil

Peppermint oil is considered to be a highly effective option for relieving pain and reducing soreness in the tissues of a muscle. This makes it a great option when trying to recover from a strenuous workout or minor injury.

Peppermint oil has also been shown to possess benefits for people with arthritis, as it relieves the inflammation that builds up in the joints. This can not only ease the pain but can also slow or even prevent the progression of their symptoms.

Lavender Oil

Lavender is a purple, flowering plant in the mint family, which is native to the Mediterranean and parts of western Asia. Synonymous with its beautiful scent, lavender has long been added to various cosmetic products, due to both its aromatherapeutic and healing properties.

Cypress Oil

Cypress is a type of tree common to parts of eastern Europe, the Mediterranean, and middle east.

Cypress oil is made using a number of different parts of the tree, including the leaves, stems, and twigs. Cypress oil soothes muscle pain as it is an antispasmodic, meaning it helps to ease cramps, spasms, and tension in a muscle.

Its circulation boosting properties then help to restore blood flow to damaged areas, reducing swelling and inflammation and promoting recovery.

Magnesium Oil

Magnesium is a mineral and alkaline metal element. Magnesium flakes can be obtained from some water sources, and these can then be converted into magnesium oil. Much like when it is used in salt form, magnesium helps reduce soreness and it eases inflammation and swelling in the joints.

Wintergreen Oil

Wintergreen is a range of plants known for their green leaves and red berries. Wintergreen oil is obtained by fermenting the leaves and helps to soothe the body through a process known as counterirritation.

This mean’s that the oil causes a mild irritation in a healthy part of the body, redirecting blood flow there. This will lead to a reduction of swelling and inflammation in the damaged areas, soothing pain in the muscle or joint and giving it an opportunity to heal.

Other Things To Add To Your Soak To Heal Sore Muscles

While the majority of muscle soaks rely on salts and essential oils to be effective, there are a few other things you can add to a bath to ease pain and help you recover. That is why, before we finish, I want to show you the best other things to add to your soak to heal sore muscles.

Apple Cider Vinegar

Apple cider vinegar is an acidic liquid made from fermented apples. Known to have both alkalising and anti-inflammatory properties, it can reduce the swelling around an area to ease pain, before directly enhancing the healing process itself, promoting a faster recovery.

Mustard Seeds

Mustard seeds can be obtained from any type of mustard plant and can be black, brown, white, or yellow in colour.

Mustard seeds promote the release of acetic acid in the body, which is required for muscular contractions. By doing this, it helps to prevent cramps and tension, relaxing the muscle and soothing many types of pain.

Hot & Cold Soaks For Sore Muscles

While adding different oils, salts, and various other things to a bath can create an effective soak, the water itself can do a great job on its own if required. How exactly the water will soothe your muscles will depend on its temperature.

Soaking in a hot bath will relax the muscles, reliving cramps, spasms, and tension, and directly soothing the muscles. On the other hand, an ice cold bath will help to relive inflammation and can promote better blood flow to stimulate recovery.

You can even add any of the muscle soak options we have already looked at to your hot or cold bath, to get the best of both worlds.

If, however, you would rather try thermotherapy by keeping it separate from your bathing experience, perhaps you should consider a cold plunge tub or a personal home sauna instead.

Final Thoughts

Muscle soaks are a time tested way to heal and soothe your tired or damaged muscles and joints in the most relaxing way possible. With the water itself offering benefits of its own, you can simply slip into the tub and let it wash all of your troubles away.

You will now hopefully have a good idea of what to add to your soak, to get the best results and experience, based on the affliction you are personally dealing with. So, all that’s left is to go and purchase your chosen oil or salt and see how it can boost your bathing experience for yourself.
