A gas generator for health is provided. The gas generator for health includes an electrolysis device, a gas mixing chamber and a gas output device. The electrolysis device is for electrolyzing water to produce a combination gas including hydrogen and oxygen. The gas mixing chamber includes a shell and a cover. The shell has an anti-explosion hole. The cover is separatably disposed on the anti-explosion hole, and the diameter of the anti-explosion hole is larger than 0.5 cm. The gas mixing chamber is connected to the electrolysis device for receiving the combination gas. A vaporized gas is generated by the gas mixing chamber and mixed with the combination gas to produce a healthy gas. The gas output device is connected to the gas mixing chamber for outputting the healthy gas to a user to breath.
