Blood pressure and hot tubs

Can you go into the hot tub with controlled blood pressure?

18 May 2016

As a rule most health spas will discourage people with medical conditions from using the hot tub (jacuzzi) or saunas however there is little research available to indicate that it is unsafe to do so.

We would recommend that you seek advice from your GP, to ensure that your Blood Pressure is stable and well controlled by means of medication, exercise and lifestyle alterations.

When you use the hot tub, like when you are performing moderate exercise, your body temperature will rise and this causes your blood vessels to dilate. When the blood vessels dilate the blood flow improves and this can actually lower your blood pressure.

The benefit of lowering your blood pressure by hot tub use however, only lasts for a brief period after getting out(10 minutes) so would not be an efficient way of treating raised blood pressure over a prolonged period of time.

When you use a hot tub the temperature should ideally be below 40 degrees centigrade and you should not use the hot tub for periods longer than 10 minutes duration.

It is also very important to avoid going from extreme heat to cold quickly as this can in fact cause your blood pressure to rise rapidly.

Please also avoid using any un-prescribed medication and alcohol at the same time as soaking in the hot tub as heat can cause side effects from these to be apparent or exacerbated.

As mentioned previously it would be a good idea to check with your GP first to ensure that there are no other clinical indications for you not using a hot tub.
