Warm-water immersion can be relaxing and comfortable, but a home spa is not the same as a professionally supervised hydrotherapy or rehabilitation programme. It should not be presented as a treatment for arthritis, fibromyalgia, depression, insomnia, cardiovascular disease, neurological conditions, chronic pain or injury.
Clinical hydrotherapy can involve assessment, prescribed exercises and professional supervision. A consumer spa provides warm water, buoyancy and massage for home use. Those are different settings and should not be described as equivalent.
For normal hot-tub use, do not exceed 40°C. Many adults prefer a lower setting. Comfort, age, health, weather and session length can all affect what is appropriate.
Stay hydrated and leave the water if you feel dizzy, excessively hot, faint, unusually short of breath or otherwise unwell. Avoid alcohol around hot-water immersion because it can increase safety risks.
Pregnant users and people with cardiovascular, blood-pressure, diabetes or other relevant conditions should seek suitable professional advice before hot-water immersion.
Cold-water immersion and hot-water immersion place different stresses on the body. Neither should be marketed as a way to boost immunity, detoxify the body or treat disease.
Use a home spa for relaxation and comfort, follow the product guidance, keep temperature sensible and seek individual advice when health conditions may affect safe use.
