8. Weight loss

There are multiple useful strategies that can help to lose weight. If you want to lose weight, you must follow some essential lifestyle changes. However, most of these strategies involve some level of discomfort like extensive exercise, abstaining from favorite foods; however, the hot tub is an easy and discomfort-free weight loss strategy. Generally, people ask “do saunas make you lose weight?” and the simple answer is YES, they do!

Glenn says that an infrared sauna or hot tub can aid with weight loss as it will relax your muscles and increase respiration. The more restful sleep, the easier it will be to reach your ideal weight.

  • Leg Kicks:

You can bend your knees at a 90-degree angle and lift it towards the surface of the water.

Specific health conditions treatment

The hot tub is considered a symbol of luxury. It is purely about indulgence! I designed the jets in the hot tub which helps to soothe aching muscles. The heat of water also helps to open blood vessels. My team pays careful attention while designing to ensure all-out therapeutic advantages of the hot tub.

I design hot tubs keeping in mind their utility for some specific treatments of medical conditions, chronic pains, and some mental issues. Following is a list of some conditions that can be treated by using hot tubs:

1. Fibromyalgia

Fibromyalgia is a disorder that results in discomforts like pain and stiffness. This disease makes it difficult for an individual to move. Relief begins with warm water; it has a greater effect on women than men. Many doctors try different medications in order to treat this disease. Giacomo, Sara, Emanuele, and Antonella summarized that the best place to get relief from fibromyalgia is in a hot tub. A single dip in a hot tub is a superb way to melt all tensions and stress. Hence there are many advantages of bathing in a hot tub.

This pain and discomfort from fibromyalgia may last for a long time, but the effective relief is as close as your backyard spa. With the help of regular hydrotherapy of this disease, the patient may enjoy:

  1. Pain relief for long term
  2. Great sense of calm
  3. Optimum blood circulation
  4. Reduction in point pain

A hydrotherapy study found out that consistent use of hot tubs improves overall wellbeing and increase energy levels. A sense of increased vitality is seen in people who are fond of soaking in the hot tub before sports. Another study was conducted in Germany on hot tub advantages and disadvantages and according to the results, hydrotherapy can be used as an effective method for those who are suffering from fibromyalgia.

2. Lower back pain

According to research estimate, 80% of people suffer from lower back pain at one point or the other in their life. It can have a severe impact on the quality of life and cause sleep loss. Chirotrust also indicates that hydrotherapy has a positive impact on the people suffering from lower back pain.

This is an easy way to get rid of that annoying pain in the lower back; in a hot tub, elevated heat enters all areas of the body including upper and lower back as well as shoulders. A single dip can provide instant relief. I have designed a variety of powerful jets that result in accumulating multiple benefits of hot springs. Customized hot tub massages also ease mobility and decrease the need for other medications. Robyn Whalen further adds that warm water promotes optimal blood circulation and diminishes pain sensory signals.

3. Decrease anxiety

If you have spent your day stressed out by your hectic routine, all you need is to soak in a hot tub to get rid of all the stress. Jacuzzi also agrees that while you are immersed in a hot tub, nothing matters more than how good you start feeling. It basically helps to balance your nervous system. Samantha Lauriello further adds that immersion boosts the release of the hormone. Dopamine is released by the nervous system in our bodies to fight with the effects of harmful stress.

4. Headache, fatigue, migraine

The one who is suffering from migraine knows that its worse than just a headache. There are many symptoms like feeling dizzy, nausea, pain on one side of the head and many others. Stress causes muscle tension which can result in a painful migraine.

To get relief from migraine and other headaches, you should soak yourself for at least five minutes (the longer the better); then take a cold compress and place it on your forehead for some time. After completing this process, return to soak in jets with cold compression application. You can continue this exercise for a few minutes and the alternating hot and cold water to lessen the intensity of your migraine.

5. Arthritis

With the chronic pain of arthritis, it can be very difficult to find an effective treatment. But for rheumatoid arthritis, health benefits of hot tub and hydrotherapy is highly recommended. Research of Khanjari and Ameri also state that bubbling water has no side effects.

According to the research by Franke, Reiner, Pratzel, Franke, Resch, 43 million people in the US are suffering from arthritis. The silver lining in the cloud is that damage can be prevented through natural ways without surrendering to a lifetime of medication. The patient can have regular sessions in the hot tub which keeps the joint moving.

Furthermore, there are a lot of exercises that are best for arthritis patients and can be performed in a hot tub; these may include leg lifting, leg curls, and bicycle kicks. If you find some difficulty to keep your balance, you can also go for a floatation belt while performing leg movements.

6. High blood pressure

When you enter the hot tub, just set your stopwatch for fifteen minutes and then check your blood pressure. As your heart starts beating, it pushes blood through your arteries and sometimes your arteries get blocked up with fatty deposits. This causes obstruction and can also damage organs. These orders lead to blood pressure issues.

Researchers Shin, Wilson and Wilson also highlight the fact that hot tubs can help get rid of blood pressure complications. Numerous medical studies show that ten minutes in the hot tub are totally safe for the treatment of hypertension.

Most of the doctors say that YES, hot tubs are considered absolutely safe with respect to patients suffering from blood pressure. However, Lorna Collier says that you just need to be a little careful if you are going through any other heart disease.

Hot tub and heart conditions

If you have a heart condition, it shouldn’t stop you from enjoying hot tub advantages – all you need to do is to be careful while soaking in it. Medical experts Cameron and George Knapp say that sudden immersion in hot water may lead your body to heat up and start stressing your heart. So, awareness is very important to keep you safe while soaking.

  1. Control water temperature.
  2. Must limit your exposure in hot water
  3. It is best to stay hydrated

Diabetics and Hot tub

Laura Isaac states that researches prove that it can help to control your diabetes. As the hot water increases the temperature the body stimulates the natural cooling mechanism. The increase in blood flow is one of the amazing health benefits of soaking in a hot tub, especially if you are unable to exercise.

Other studies show that hot tub reduces blood glucose level in people suffering from diabetes. While you are taking a look at these health benefits of a hot tub, also see what Dr. Anthony Jay has to say about the advantages of bathing in a hot tub:

Be aware of your insulin

You should be especially aware of hot tubs side effects if you take insulin. It’s better to remove an insulin pump before entering in hot water tub; the body starts absorbing insulin due to heat. It’s so important to stay hydrated and keep your temperature in check to get maximum advantages of bathing in a hot tub.

As per the medical studies, it might be a way to beat diabetes. A journal published in England indicated that hot tub therapy helps out a group of adults who are having type 2 diabetes. It improves sleep patterns and lowers blood sugar levels.
