Laughter Therapy Found Effective for Dry Eye Disease

A new study suggests that laughter exercises may be as effective as eye drops in alleviating dry eye symptoms.

Researchers from China and the UK conducted a study involving 283 participants aged 18-45 with dry eye disease.
Participants were divided into two groups: one performed laughter exercises, and the other used 0.1% sodium hyaluronic acid eye drops.
The laughter therapy involved repeating specific phrases to engage ocular muscles, performed four times daily for eight weeks.
Results showed that both treatments significantly reduced symptoms, with laughter therapy proving non-inferior to eye drops.
Laughter therapy also demonstrated additional benefits, including improved tear film stability and mental health scores.
