A good laugh

Chuckle. Chortle. Giggle. Guffaw!

The simple act of laughing can give our health and well-being a big boost, experts say.

Here are 10 benefits of a good laugh. (Warning! It can be contagious.)

1. It eases stress.
Feeling anxious, nervous or under pressure? A hearty laugh can reduce stress hormones – and also relax your muscles for up to 45 minutes. Plus, when you’re laughing, you aren’t dwelling on what’s stressing you out.

2. It helps your heart.
Laughter improves blood vessel function and increases blood flow, which can protect you from a heart attack and other cardiovascular problems.

3. It can help you lose weight.
Laughing regularly may help you slim down. One study found that laughing 100 times is equivalent to 15 minutes on an exercise bike or 10 minutes on a rowing machine.

4. It increases oxygen levels.
A good belly laugh can deliver more oxygen to your heart, lungs and other organs, improving their function.

5. It boosts your immunity.
The positive mindset and uplifted spirits that linger after laughter can help your body release antibodies that fend off infections.

6. It lifts your mood.
Serotonin, a chemical released by the brain when you laugh, improves mood and combats depression. Even a forced laugh can spur a release of the “happiness molecule.”

7. It can help with pain management.
Your body releases endorphins when you chuckle. This can ease pain and provide a sense of euphoria – commonly known as a “runner’s high.”

8. It helps build relationships.
A good sense of humor is what many people look for in a friend or partner. It can build and strengthen bonds with friends new and old.

9. It doesn’t cost a dime.
Laughter is free, so enjoy this no-cost way to make you healthier.

10. No joke: It really is contagious.
One study found that our brains respond to the sound of laughter by preparing our facial muscles to join in. So, when you laugh, you’re spreading all the healthful benefits to others around you. Share a good laugh with somebody today!
