Sauna vs. Jacuzzi: What's the Difference?

Edited by Aimie Carlson || By Harlon Moss || Published on March 4, 2024
A sauna is a small room or house designed for experiencing dry or wet heat sessions, while a jacuzzi is a large tub or small pool filled with heated water and equipped with underwater jets for massage.

Key Differences

A sauna is a room or enclosure where dry or wet heat is used to induce sweating and relaxation. It typically operates at high temperatures, ranging from 70°C to 100°C (158°F to 212°F), and can be either a traditional Finnish sauna with dry heat or a steam room with moist heat. In contrast, a jacuzzi, also known as a hot tub or spa, is a large tub or small pool filled with heated water and equipped with jets for hydrotherapy and massage. The water temperature in a jacuzzi is usually maintained between 37°C and 40°C (98.6°F to 104°F), providing a warm and soothing environment.
Saunas are primarily used for detoxification, relaxation, and improving cardiovascular health through the exposure to high temperatures. The heat in a sauna promotes sweating, which helps remove toxins from the body and can relieve muscle tension. Jacuzzis, on the other hand, are known for their therapeutic benefits, particularly in relieving muscle soreness and joint pain through the combination of warm water and massage jets. The buoyancy of the water in a jacuzzi reduces the pressure on joints and muscles, making it an ideal setting for relaxation and pain relief.
Both saunas and jacuzzis offer health and relaxation benefits, they differ in their approach, with saunas focusing on dry or wet heat exposure and jacuzzis providing hydrotherapy through heated water and massage jets.
