Drug Free Steam and Heat Therapy System for Sinus Congestion Relief

Abstract

Sinus congestion is a common upper respiratory condition characterized by nasal blockage, mucus accumulation, facial pain, and pressure due to inflammation of the sinus cavities. Continuous dependence on medication may result in side effects, creating the need for safe, non-invasive, and drug-free supportive solutions. This paper presents the design and development of a Drug-Free Steam and Heat Therapy System intended to provide symptomatic relief through controlled steam inhalation and localized heat therapy. An ESP32-based control unit regulates therapy duration, temperature limits, and automatic shutoff to ensure safe operation. The proposed system is low-cost, user-friendly, and suitable for home-based sinus congestion relief applications.
