Meditazione, yoga, tai chi o anche ritiri spirituali e altre forme di intervento su corpo e mente non hanno semplici effetti rilassanti, ma lasciano una traccia molecolare positiva sul nostro organismo, favorendo l'attivazione di geni protettivi e il parziale spegnimento di altri che possono causare problemi, e riducendo inoltre la risposta infiammatoria cronica che di per se stessa è pericolosa e legata a malattie tra cui cancro e depressione.
Lo rivela una ricerca svolta tra le università di Coventry and Radboud e pubblicata sulla rivista Frontiers in Immunology. Non è la prima volta che si evidenzia l'effetto sull'organismo di interventi su corpo e mente, delle pratiche meditative o di antiche discipline orientali. Ma questo è il primo lavoro - basato sull'analisi di 18 studi precedentemente pubblicati per un totale di 846 partecipanti e per una durata complessiva di 11 anni - che tenta di essere esaustivo su questo fronte.
