How Do Hot Tubs Fight Inflammation?

Hot tubs are well known as places for recreation, relaxation, and socializing. But they can also provide therapeutic relief. Hot water has long been a primary ingredient in hydrotherapy. Combined with the massage provided by the hot tub’s water jets, many different medical conditions can be alleviated by hot tub use. Inflammation is one of them. How do hot tubs fight inflammation? In this article, we’ll find out.

What Is Inflammation?

Inflammation is a protective mechanism initiated by white blood cells. They rush to areas of the body that have been injured, attacked by viruses, bacteria, disease or other aggravating factors. Inflammation is often characterized by heat, pain, stiffness, swelling, and redness of the tissues. Inflammation can be temporary (acute) or long-lasting (chronic.) In extreme cases, inflammation can result in headaches, fever, chills, muscle stiffness, fatigue, and loss of appetite.

How Do Hot Tubs Fight Inflammation?

The main characteristics of the water in a hot tub – heat, massage, and buoyancy – produce conditions that are ideal for the treatment of inflammation. They can provide both physiological and physical respite from the symptoms of inflammation and temporarily reduce pain. Following are some of the different ways in which using a hot tub can help mitigate the effects of inflammation.


Heat provided by the hot tub water reduces pain caused by inflammation while also promoting healing. Heat calms sensory receptors and reduces the frequency and intensity of pain signals being sent to the brain. It also relaxes muscles which takes pressure off bones, tendons, and joints. The warm water increases the internal body temperature which results in a faster heart rate and increased blood flow which bathes the injured tissues in oxygen and nutrients. Meanwhile, waste products and damaged cells are also flushed away. Heat also increases the metabolism and releases more energy to help with recovery processes.


The manipulative effects of the hot tub water jets increase the blood flow to affected areas. Consequently, this increases the flow of oxygen and nutrients which help promote tissue repair. Debris and damaged materials resulting from deterioration caused by inflammation are carried away and disposed of. Massage can also stimulate the production of pain-relieving hormones which will ultimately reduce inflammation-related pain.


The buoyancy created by water pressure can reduce the amount of weight experienced by the bones, joints, and other parts of the body. The effects of gravity are reduced and the body feels lighter because of it. For those who suffer joint pain from inflammatory diseases such as arthritis, buoyancy can provide tremendous relief by allowing healing to occur and reducing the symptoms of inflammation. Water buoyancy can also help increase the range of motion and reduce friction in joints which results in lower levels of inflammation.

Blood Circulation

Increased blood circulation bathes inflamed tissues in greater amounts of oxygen and nutrients which speeds up the healing process. Damaged cellular tissues are flushed away and allow for the regeneration of new, healthy tissues. Inflammatory diseases often reduce the mobility of the sufferer which, in turn, reduces the rate of blood circulation. By improving blood flow, inflamed body parts become easier to move.


It’s been found that lack of sleep can result in increased instances of inflammation. Spending time in a hot tub before going to bed has been shown to result in falling asleep faster as well as having a more restful and uninterrupted sleep. Using a hot tub to create better sleeping patterns can result in a reduction of inflammation.
