Recent research by US scientists shows that smiling can help improve short-term memory in the elderly, while having a positive impact on brain activity.

In the study, the team conducted tests in two groups of older people, each group of 20 members in the first 20 groups were asked to maintain a comedy routine for about 20 minutes a day. In contrast, the second group does not apply this test method in the same time.

Later, Loma Linda University team analyzed their saliva samples to test hormone levels and performed memory tests.

According to the test results, the elderly in the first group have a higher score than the rest. Cortisol levels, which are associated with signs of stress in humans, are also lower in this group.

ABC News quoted Dr. Gurinder Bains as saying that a smile makes the body release neurotransmitters endorphin and transmits dopamine to the brain, helping to improve overall human activity and function . This can improve the functions of the immune system and brain activity. Changes in this activity positively affect memory and recall ability.

The team also concluded that smiles play an important role in daily life, helping people relieve stress, lower blood pressure and improve mood.
