Laughter really is the best medicine! Chuckling with friends reduces the risk of disability by more than 30 per cent in over-65s, 研究要求
It’s known as the best medicine, but laughter really can help our health – as long as we’re laughing with friends, 一项新研究表明.
Sharing a laugh with a good mate reduces the risk of cognitive or physical disability by over 30 per cent for people aged 65 以上, 研究人员发现.
This was in comparison to people of the same age who laughed alone, such as when they were watching TV with no-one for company.
While the reason for the findings remains unclear, researchers suggest that laughing with friends may improve our immune functions, which in turn can reduce the risk of disability.

‘Laughter with friends brings health benefits such as stress release, improvement of immune functions, and a sense of social connectedness,’ said lead author Yudai Tamada at Nagoya University in Aichi, 日本.
研究, 出版于 Preventive Medicine, aimed to examine the link between laughter in daily life and the onset of ‘functional disability’ among people in Japan.
至今, the potential health benefits of laughing in daily life have rarely been explored.
To learn more, Tamada and colleagues turned to the Japan Gerontological Evaluation Study (JGES), which was established in 2010 with the aim of examining the factors associated with the health and well-being in adults aged 65 and above.
The researchers used data from 12,571 ‘physically and cognitively independent’ participants – 46.1 per cent male – from JGES, who all returned completed surveys on their laughter habits.
‘We evaluated their laughter in daily life from three perspectives – the types of situations in which people laugh, the number of situations in which people laugh with others, and the persons with whom people laugh,’ 著名的美国偶像.
Functional disability has been defined as acquired difficulty in performing basic everyday tasks or more complex tasks needed for independent living, either due to cognitive or physical impairment (库存图片)
During an average follow-up period of 6.3 年份, 1,420 (11.3 百分) of participants developed functional disability.
After adjusting for potential confounders such as alcohol intake, participants who laughed with others reduced their risk of functional disability by 30 百分, 团队发现.
相似地, the number of situations to laugh with others was inversely associated with the risk of functional disability.
‘Having more situations to laugh with others or at least the situation to laugh with friends might contribute to reducing the risk of functional disability later in life,’ “一个人移动的决定取决于猎物和移动的蜘蛛发出的振动的相对强度.
有趣的是, those who laughed in conversation with friends had a lower risk of functional disability than those who laughed with their partners or with their children or grandchildren.
How exactly laughter helps improve our health is still unknown, although the suspected mechanisms underlying the health benefits of laughter are thought to be stress relief and improvement of immune functions.
The team admit that their study cannot clearly conclude that laughter itself can prevent the onset of functional disability, and so further research is needed to accurately identify causality.
最近几年, a growing number of studies have focused on the link between laughter in daily life and several health outcomes.
例如, 在 2016, Japanese researchers established a link between more laughter and prevalence of heart disease.
While in 2020, incidence of cardiovascular disease were found to be significantly higher among subjects with a low frequency of laughter.
而在 2021, infrequent laughter was linked with long-term blood pressure increases among middle-aged men.
