Is this true??? if so, i just found a great weight loss tip!!? -

a 20 second laugh is equivilent to a 90 second sprint! my doctor told me this and i just wanted to know if any of you have ever heard this before?

haha, don t think so dear, but laughing is good! Keep it up!

No...But laughing is fun so carry on laughing

i don t think so

I don t know that this particular number is true but I do know that laughing does burn calories.

Nope and yeah. Laughing will reduce stress. But it won t do much with the weight loss.

I think maybe they re referring to the high you feel...not calorie burning. Certain endorphins are released during cardio, also called a runners high . Maybe the same neurotransmitters are released during a long laugh. As far as fat burning and weight loss...not likely.

ah, yes is the answer, but not in the way you are thinking.Laughing flexes many muscles in your face, but running only requires around 20, so in terms of gross muscle training yes, it s kinda true.However, you burn calories by elevating your heartrate and keeping it there, so think about this after a 20sec. laugh are you as sweaty and tired as you are after a fast lap around a track?no is the answer, so you can t lose weight by laughing, but yes, it moves more muscles.
