Respiration increased during laughter
changes the heart rate. The heart begins to accelerate, to then slow down (in a
phase of relaxation dominated by the calming influence of the parasympathetic),
heart rate decreases permanently until you reach a low frequency. Relax the
arteries and increases the caliber of the blood vessels, reducing blood
pressure. It is an effective weapon in the prevention of heart attacks, used in
many American hospitals Cardiology services.
Many Doctors says that a good daily dose of
laughter can have similar effects as physical exercise for the cardiovascular
system by stimulating blood circulation. As a first step, by accelerating the
heart rate laughter, in the same way as jogging, building muscles,
strengthens the heart and the blood circulation and improves oxygenation of the
heart muscle, which reduces the risk of a blood clot.
The benefits of laughter continue long after the giggling had stopped. The muscles are more relaxed and as blood pressure and heart rate (in a second time) descend below normal, the heart is subjected to less stress and it is good for human health.
