IT’S NOT JUST A MASK UNSAFE MASK USE
INCREASES RESPIRATORY INFECTIONS Wearing a cloth mask significantly increases the risk of flu-like illness. Masks absorb moisture and can become reservoirs of bacteria and viral particles.
MENTAL HEALTH IMPACTS OVERLOOKED Those with exemptions for mental health often face discrimination or disbelief of their condition. Masks can cause stress and anxiety, aggravating pre-existing symptoms before, during, and after use.
BULLYING AND SHAMING Those who are unable to wear a mask will be confronted multiple times a day regarding mask use. Children who are unable to wear masks face bullying from other children and even their parents.
IMPAIRS SOCIAL DEVELOPMENT Children rely on the nose and lips to identify their parents. Masks muffle sound, hide facial expression, and prevent lip reading. Communication relies heavily on lip movement, especially for the hearing impaired.
POSES PUBLIC SAFETY RISKS Masks compromise safety and enable anonymous crime. Being able to identify people and children in distress is paramount for safety; this is especially important for identifying missing children.
CAUSES HEADACHES AND DIZZINESS Masks impair breathing, can cause shortness of breath and have other negative side effects. Masks increase carbon dioxide and reduce oxygen concentrations inside the mask.
