Deaf and mute people are capable of laughing just like anyone else. Laughter is a natural human response to humor and joy, and it is not dependent on the ability to speak or hear. Deaf and mute people may laugh differently than hearing people, but they still experience the same emotions and sensations of joy and amusement.
There are many benefits to laughter, both physical and mental. Laughter can help to reduce stress, improve mood, and boost the immune system. It can also help to strengthen social bonds and create a sense of community. Deaf and mute people can enjoy all of these benefits of laughter, just like hearing people.
