#1 Lowers Blood Pressure
According to Public Health England, high blood pressure affects more than 1 in 4 adults in the UK. In fact, it’s estimated that 1.5 billion people will be affected by 2025. High blood pressure can lead to serious medical conditions, such as heart disease, strokes and heart failure. Therefore, it’s more important than ever to keep your blood pressure at a heathy level (between 120/80 to 140/90).
But how can a hot tub session achieve this? An experiment carried out in Saskatoon, Canada, holds the answer. 21 people with hypertension and 23 people with normal blood pressure were subject to a 10 minute soak in a 40°C hot tub. During the session, the diastolic pressures of both groups dropped, although their measurements returned to the normal levels 10 minutes after they left.
So what is the science behind it? The heat causes the blood vessels to dilate, therefore reducing the strain on the heart. It also increases the production of nitric oxide, a molecule that dilates blood vessels. As dilation increases, it creates less vascular resistance to help the blood circulate more efficiently. Therefore, your blood pressure will begin to decrease.
#2 Relieves Stress and Tension
Regular hot tub use helps to relieve stress and tension through a combination of buoyancy, heat and massage. First, buoyancy. Being submerged in water eases pressure in the joints and muscles. The uniform pressure of the water can also improve your balance.
Second, the heat from the hot tub dilates the blood vessels. This promotes blood flow, which in turn helps sore and tightened muscles relax. Furthermore, improved circulation can eliminate the buildup of lactic acid caused by some types of exercise.
Finally, hot tub jets will provide therapeutic massages. These will stimulate the release of endorphins, otherwise known as the body’s natural painkiller. Many of the Jacuzzi hot tubs available from Wensum Pools have hydromassage seats. They knead and relax muscles in the back and legs for a full-body massage, while targeted shoulder and lower back jets provide tension relief.
#3 Minimise the Pain of Arthritis
The Arthritis Research Campaign suggests a soak in a hot tub as an effective way to apply heat to arthritic joints. Some of the benefits include muscle relaxation, reduced pain and joint stiffness, as well as greater ease when performing daily activities.
“Research has shown warm water therapy works wonders for all kinds of musculoskeletal complaints, including fibromyalgia, arthritis, and low back pain,” reveals Arthritis Today. What’s more, hydrotherapy also improves sleep patterns and fights depression, which is incredibly beneficial for arthritis sufferers. So much so, the Arthritis Foundation now highly recommends warm water therapy to its patients.
#4 Reduces Diabetic Blood Sugar Levels
According to a recent study by the New England Journal of Medicine, a soak in a hot tub can simulate the benefits of exercise. Patients with type 2 diabetes soaked in a hot tub for 30 minutes a day, 6 days a week, for 3 weeks. As a result, their blood sugar levels fell by an average of 13%. One of the subjects even reduces his daily dose of insulin by 18% after only ten days of the study!
