Coffee May Slow Cellular Ageing in Severe Mental Illness
A recent study found that drinking coffee might help slow down how quickly cells age in people with serious mental health conditions.
The researchers looked at something called telomeres, which are like tiny caps on the ends of our chromosomes that get shorter as we get older.
People who drank about 3-4 cups of coffee a day had longer telomeres, meaning their cells were biologically younger.
This was especially important because people with mental health conditions often have shorter lifespans due to age-related diseases.
The study suggests that moderate coffee drinking could be beneficial, but drinking too much might not have the same positive effects.
However, the researchers noted that more studies are needed to fully understand this connection.
Moderate coffee consumption (3-4 cups/day) linked to longer telomeres in adults with severe mental disorders
Participants drinking 3-4 cups of coffee appeared biologically about five years younger than non-drinkers
Study involved 436 adults with schizophrenia spectrum or affective disorders from Norway
Telomere length measured from blood samples, with moderate coffee drinkers showing the longest telomeres
Researchers suggest coffee's antioxidants and caffeine may reduce inflammation and oxidative stress, benefiting cellular ageing
