Soporific

The soporific nature of the forest walk helped him feel more connected to nature.

The soporific scent of the flowers in the garden made me feel drowsy.

The sound of the ocean waves can be quite soporific for some people.

The soporific sound of the ocean waves lulled her to sleep.

The calming sound of the ocean had a soporific effect on me.

The soporific nature of the waterfall created a calming environment in the park.
