According to a new study by Deep Longevity, mental health has a greater impact on aging speed than smoking and certain diseases. People who are particularly prone to premature aging are lonely and unhappy, who do not sleep well.
As we age, various molecular damage accumulates in our cells, leading to overall body aging and the development of various diseases. In some people, these molecular processes are stronger than others. This situation is often referred to as accelerated aging.
Fortunately, an increase in aging speed can be detected even before its first effect appears. Deep Longevity is developing models to predict aging speed based on epigenetic changes (methyl group-DNA connection), changes in chromosome ends (telomeres), and gene expression and various metabolite concentrations.
These models can be used to develop anti-aging therapies. However, now a team of American and Chinese scientists have shown that any such therapy should target not only physical health, but also mental health. The authors of an article published in the journal Ageing in the United States evaluated the effects of loneliness, poor sleep and dissatisfaction on aging speed. This proves to be very important.
Scientists have applied deep learning technology to develop a new "aging molecular clock" based on blood test results and biometric data from 11,914 Chinese adults.
Results, researchers found signs of accelerated aging in people with a history of stroke , liver disease and lung disease, smokers, and people with a vulnerable mental state. It even turns out that loneliness and unhappiness, anxiety and poor sleep can increase a person's biological age better than continuous smoking. Other factors associated with accelerated aging include living in rural areas, which may be due to the low availability of healthcare services.
Therefore, according to scientists, the psychological aspects of aging should not be ignored either in research or in the development of anti-aging therapies. Mental and psychosocial conditions are one of the most reliable signs of health and quality of life, but they are not actually taken into account in modern health care systems.
