A study in Sweden showed that a person's voice can affect heart health. The greater the volume, the greater the risk of heart disease. Therefore, it is okay to laugh but not too hard.
According to this study, the harder a person's voice the blood pressure will increase. For those who have problems with the heart and blood vessels, this increase in blood pressure can increase the risk of heart attack and stroke.
Even the increase in blood pressure as revealed in the study can already be observed at a noise level of 65 decibels. According to the researchers, people who laugh with average noise levels are included in this category.
Heart Rate Variability (HRV), a measure of the ability of the heart and the autonomic nervous system to adapt to the environment is also affected by sound. But for this one, a health expert still doubts the truth.
Eric Topol, MD, of MensHealth says that HRV is indeed a risk factor for cardiovascular disease. But according to him, it is controversial to say that the value of HRV can be used to measure the exact risk of heart disease.
"Why? Because sound and environmental stimuli affect a person in terms of autonomic nervous system, while others do not.Examples, certain sounds can make a person's heart rate jump, but for you no problem," said Dr Topol as quoted from MensHealth.com, Wednesday (15/05/2013).
Regardless of the controversy, a calm atmosphere can indeed nourish the heart. Meditation for 15 minutes, for example, may increase parasympathetic nerve activity and indirectly also decrease heart rate, as recently revealed in a study in Australia.
