Is it good to laugh and is it good for the body? Can smiling really be healthy?

Laughter soothes the nerves and makes people feel at ease. Regulating endocrine is a great benefit to the body! So laughing a lot can make people younger.

Laughing more is good for the human body.

It's good to laugh, so that you can look good, and smile for ten years.

Laughing is good for the body, but don't overdo it or it will wrinkle.

Okay, smile, ten years less.

It's good to laugh. But it's not good to laugh too much.

Smiling more can be healthy, and there are five specific aspects:

1. Lower blood pressure and protect the heart and brain.

Japanese researchers found that when the test participants were shown on a comedy variety show, blood flow to their internal organs increased and blood circulation improved. In addition, comedy movies that make people laugh will dilate blood vessels, improve cerebral blood supply, and lower blood pressure within 24 hours.

2. Eliminate stress and depression.

While laughter has an effect on physical health, it also triggers psychological reactions, which is why people feel relaxed and upbeat after laughing. In a new study, scientists have found that a single laugh can reduce levels of three stress hormones – cortisol, adrenaline and dobuck – in the body, respectively.38 Researchers say these seemingly short-lived emotional influencers may play a role in mental illness in the long run.

3. Improve immunity.

Dr. Lee Burk of Loma Linda University in the United States has found that laughter can reduce the level of inflammation in the body and increase the activity of K lymphocytes (a type of immune cell that plays a role in fighting viruses, parasites, tumors, etc.). Therefore, laughter helps to strengthen the body's immune system function and protect the body from diseases.

4. Relieve pain.

Through a series of trials, researchers found that when participants laughed with a group of people, their pain thresholds were significantly higher and they showed better pain tolerance. Subsequently, when the conversation returned to something less funny, the participant's pain threshold dropped. Experts say laughter relieves pain because the body releases endorphins as a result.

5. Burn heat.

Researchers at Vanderbilt University Medical Center in the United States said that although laughter is not a substitute for exercise, laughter lasting 10 to 15 minutes can burn up to 40 calories (about kilojoules). Not only that, but laughter also gives work to body parts such as the abdomen, shoulders, and diaphragm.
