An acute intervention experimental study on the effects of green and blue environment exposure combined with tai chi exercise on the emotional health of elderly males

Acute exposure to different types of green and blue environments exerts positive effects on the short-term emotional health of elderly males. On this basis, acute exposure to different green and blue environments in combination with Tai Chi exercise further enhances short-term emotional outcomes in elderly males. Further, following this combined acute effect, continuous exposure to different green and blue environments maintains positive emotional changes for a longer duration during the recovery period. The environment types, ranked by the magnitude of acute positive changes and maintenance effects, are as follows: blue environment > balanced green-blue environment > green environment > conventional environment.
