Physiological barriers to communication are obstacles that impact effective communication because of the condition of the human body and mind. These barriers are related to the limitations of the human body and mind, such as memory, attention, and perception. Some examples of physiological barriers include vision impairment, hearing impairment, language disorders, speech impairments, and physical disabilities. Other factors that can contribute to physiological barriers include poor listening skills, information overload, inattention, and emotions. Distractions such as background noise, poor lighting, uncomfortable sitting, unhygienic room, or an environment that is too hot or cold can also affect peoples morale and concentration, which in turn interfere with effective communication. To overcome physiological barriers, individuals may need to train themselves to improve their communication skills or use alternative forms of communication, such as written communication.
