Looking at original works of art in galleries can help immediately relieve stress, a study has found.
Viewing art also has a "positive impact" on the immune system, the nervous system, and the network of glands that release hormones, according to researchers.
The findings suggest art does not just move people emotionally, but can also calm the body, they added.
The study by experts at King's College London involved 50 people aged 18 to 40.
Half viewed original artwork by the likes of Van Gogh and Gauguin at the Courtauld Gallery in London, while the other half looked at copies of the same paintings in a non-gallery environment.
The two groups wore sensors that continuously measured their heart rate and skin temperature during the 20-minute session, with saliva samples collected pre- and post-viewing.
From these samples, researchers found that levels of the stress hormone cortisol fell by an average of 22% among those viewing original art, compared with just 8% among those viewing reproductions.
Certain cytokines – proteins that act as messengers for the immune system – linked to stress and chronic disease also fell by 30% and 28% respectively among those in the gallery, with no changes among the other group.
Tony Woods, researcher at King's College London, said: "The research clearly shows the stress-reducing properties of viewing original art and its ability to excite, engage and arouse us simultaneously."
"Stress hormones and inflammatory markers like cortisol, IL-6 and TNF-alpha are linked to a wide range of health problems, from heart disease and diabetes to anxiety and depression."
"The fact that viewing original art lowered these markers suggests that cultural experiences may play a real role in protecting both mind and body."
The study also found that art engages the immune, nervous, and endocrine systems, which are responsible for releasing hormones.
Researchers detected signs of excitement among those viewing art in the gallery, including a dip in skin temperature, overall higher heart rates and a variation in heartbeat patterns.
Woods said: "From a scientific perspective, the most exciting outcome is that art had a positive impact on three different body systems – the immune, endocrine and autonomic systems – at the same time. This is a unique finding and something we were genuinely surprised to see."
"In short, our unique and original study provides compelling evidence that viewing art in a gallery is 'good for you' and helps to further our understanding of its fundamental benefits. In essence, art doesn't just move us emotionally – it calms the body too."
Each person's emotional intelligence was also assessed before the study using questionnaires.
However, researchers suggest this had no impact on individual responses.
Jenny Waldman, director at the Art Fund, which co-funded the study, said: "This study proves for the first time what we've long felt at Art Fund – that art really is good for you."
"What's particularly exciting is that the findings show these benefits are universal – anyone can experience them."
"We want to encourage everyone to make time to visit their local museum or gallery and experience these powerful effects for themselves."
