This analysis is based directly on a large-scale prospective cohort study, the Copenhagen City Heart Study (2018), which followed more than 8,500 participants for 25 years. This type of observational evidence shows that playing tennis is correlated with an estimated gain in life expectancy of 9.7 years compared to a sedentary lifestyle. Although this is a correlation and not a direct causality, research suggests that this positive impact is largely explained by the strong social interactions required by the sport. Physically, the alternation of short, intense efforts stimulates endurance, while repeated footwork reinforces the strength and structure of the body. The constant challenges of coordination and rapid decision-making engage cerebral plasticity, promoting mental vitality. Finally, the collective dimension of tennis proves to be an excellent way to cultivate regular human relationships, a key ingredient for lasting well-being.

What the graded evidence says

Evidence
C

Linked to, not proven to cause.

Effect
difference in life expectancy by leisure sport vs sedentary reference (observational) — adjusted gains vs sedentary: tennis ~9.7 yr, badminton ~6.2 yr, soccer ~4.7 yr, cycling ~3.7 yr, running ~3.2 yr; single cohort, associational
Measured on
adults in the Copenhagen City Heart Study (single Danish cohort, ~8,500 people)

What’s uncertain

These are associations from one observational cohort; healthier or more social people may gravitate to these sports. The specific '~10 years from tennis' figure is the top of the range and shouldn't be read as a causal, individual guarantee.
