What Happens to Your Body When You Get Into a Hot Tub

A whirlpool bath is not just a hot bath. The temperature and pressure of the water act on the body simultaneously, triggering very specific physiological mechanisms.

Blood vessels dilate

When hot water comes into contact with your skin, it increases blood flow and, with it, the amount of oxygen reaching your tired muscles. This process is called vasodilation, and it’s what causes that feeling of relief that sets in almost immediately.

The body releases its own painkillers

Hydromassage stimulates the production of endorphins, the neurotransmitters that the body naturally produces to reduce pain and improve mood. That’s why, after a session, you not only feel your muscles relax—you also feel better overall. This is no small thing for those who live with high levels of stress.

Joints become more flexible

Deep heat acts on soft tissues and joints, making them more pliable. For athletes who push themselves to the limit, but also for people who spend many hours in front of a screen or behind the wheel, this means less stiffness and a lower risk of long-term injuries.

A fact worth remembering

15 minutes at 38 °C 
is enough to deeply relax the muscle fibers.

No additional time or higher temperature is needed. This combination allows heat to penetrate the tissues without placing additional stress on the body. Simple, yet backed by exercise physiology.

Recovery is also part of training

It doesn't end when you stop working out or when you leave the office. It begins when you give your body the conditions it needs to recover.

Hydromassage has a simultaneous effect on circulation, the nervous system, and the joints. It has no side effects, and results are noticeable from the very first session.
