"While foul odors are often dismissed as a mere "comfort" issue, scientific evidence proves that odor pollution has severe physical and mental consequences. Continuous exposure to bad smells triggers evolutionary defense mechanisms, leading to chronic stress and somatic symptoms in the body."

4 Major Health Impacts of Foul Odors:
- Physiological Reactions: Nausea, headaches, shortness of breath, and sleep disorders caused by the stimulation of the vagus nerve.
- Psychological Impact: Increased anxiety and stress as the brain remains in a constant state of alarm due to the "behavioral immune system."
- Lifestyle Restrictions: Deteriorating quality of life as individuals avoid going outside, socializing, and exercising.
- Persistent Sensitivity: The brain increases sensitivity to smells perceived as threats, causing them to be felt much more intensely than normal.
While research links the loss of smell to appetite loss and increased risk of early mortality, experts emphasize that combating odor pollution must be a "public health" priority.
