All things considered, most of the scientific evidence available today doesn’t show harmful effects for people with high blood pressure soaking in a hot tub. And while there is a school of thought that prefers these people NOT soak in a hot tub, the evidence shows no negative side effects from a 10-minute hot tub soak. In fact, studies in Canada and the United States show that heart rates and blood pressures during and after a 10-minute soak were not adversely affected.
Contrary to some commentaries, soaking in a hot tub or sitting in a sauna does not cause a heart attack or perpetuate heart problems. And although there may be a minor drop in blood pressure, it’s not dangerous. But whatever the case, its always prudent to check with a doctor prior to any hot tubbing – in other words, better safe than sorry. Most importantly, moderation is key, in terms of water temperature and the length of time soaking and sitting (10 minutes).
Some studies actually suggest that the heart and cardiovascular system are getting a “workout” when one sits in a hot tub. Blood that’s close to the skin surface is warmed up, and circulates throughout the body, where it warms the internal organs and deep tissue. All in all, this makes for an increase in heart rate, while decreasing blood pressure. Indeed, in health facilities such as the Mayo Clinic, hot water hydrotherapy is being routinely used to improve cardio-health.
Without getting overly scientific, studies have shown that the entire nervous system experiences better balance when the body is submerged in warm water. And better balance contributes to a reduced risk of cardiovascular disease, amongst other health benefits. Interestingly, the nervous system reacts to the warm water in a hot tub, in the same way that it reacts to meditation. Needless to say, reduced stress is critical for a healthy heart and healthy blood pressure.
Whether it’s heart health or blood pressure, there are specific hot tub water temperatures that are industry recommended. These range from 37.5C° - 39.0C° (or 99.5°F – 102.0°F). But by any definition, 40C° (104F°) is the maximum temperature for health safety. And in terms of risk, it’s always best to consult a doctor, whether it’s about heart issues, blood pressure, or pregnancy. As with anything, moderation is best, and that includes water temperature and soaking time.
