Heating some molecules, particularly large, biological molecules such as proteins or nucleic acids, will cause them to change shape or even to break up.
The air comes through the diffusers in much larger velocities and different temperatures than the ones tolerated in the space. Due to diffusion, the velocity and the temperature differences are gradually decreased until they reach the tolerable limits.
Aromatherapy diffusers are devices that are used to disperse essential oils (highly concentrated extracts from flowers, leaves, and other plant parts) into the surrounding air. According to the ancient practice of aromatherapy, spreading the scent through the air allows the essential oils to activate smell receptors in your nose, sending messages to the brain and influencing your emotions and nervous system.
