This helps participants focus on inner peace and awareness.

The Silent Protest of the Suffragettes
During the early 20th century, women in the UK, led by the suffragette movement, used silence as a form of protest to draw attention to their struggle for voting rights. This silence was powerful in its contrast to the loud political arguments of the time and symbolized the oppression women faced in their society.

Life-Saving Gestures Everyone Should Know
These gestures can help in critical situations when someone cannot speak or call for help. Everyone—adults and children—should be familiar with them.

This gesture was created during the pandemic to silently ask for help in situations of domestic abuse (e.g., during video calls or in public):

  • list-1
    Raise your hand with the palm facing forward.
  • list-2
    Tuck your thumb into your palm.
  • list-3
    Fold your fingers down over your thumb — forming a fist with the thumb inside.

A universal sign for choking or not being able to breathe due to a blocked airway:

The person clutches their neck with both hands.
The hands form a “C” shape around the throat.

!
If you see this, act quickly — perform the Heimlich maneuver or call emergency services.

A person in danger may silently point at their abuser while looking at a bystander, signaling that they need help.

The combination of eye contact + pointing can alert someone without using words.

  1. 1 Help

    Place one fist (thumb up) on the open palm of the other hand and raise both hands.

  2. 3 Danger

    Strike one fist against the open palm of the other hand.

  3. 2 Police

    Tap your chest with two fingers, mimicking a police badge.
