Laughter effects on After Meal bG in T2D


laughterLaughter is timeless. A study published in Diabetes Care 10 years ago, shows that laughter can be beneficial for after meal blood glucose levels. 

Negative emotions like anxiety, fear, and sadness can raise a blood glucose. If Newtons’s Laws hold true in this case, positive emotions like laughter should have the opposite effect on glucose levels.

This study was the first of its kind to test the effects of laughter on blood glucose levels. The purpose of this study was to clarify changes in the blood glucose level after laughing episodes in patients with diabetes.

This fun experiment was conducted over 2 days on 19 patients with T2D treated with insulin. The patients were followed before, during, and after a comedy show.

These results suggest a significant suppression of the postprandial glucose by comedy show in patients with diabetes. Presumably the participants were laughing at the comedy show.

The physiologic reasons behind the controlled after meal blood glucose may include the acceleration of glucose utilization by the muscle motion during the comedy show.

It’s possible that positive emotions such as laughter suppressed the elevation of blood glucose level by mitigating the release of stress hormones, which would evoke the release of glucose for a “fight or flight” response.

Bottom line: you probably don’t need a good reason to laugh. But if you have T2D and you’re seeking a silly way to control after meal glucose levels — here’s your chance.
