He tried to breathe, but the air in the hut was suddenly stifling.

If there is no other room and the air is stifling, then the window should be opened from the top, not the bottom.

The air was stifling and nearly made me sick.

Moreover, the air had become so hot and stifling that she could scarcely breathe.

The air was stifling, both from the heat of the day and the candles in the magic lantern.

The air was hot and stifling, making it difficult to breathe.

Even at night the air is stifling despite the usually present breezes.

As in my dream, the air was hot and black and stifling.

The air was stifling even for us who stood in the shadow of the porch.

The air was so stifling she thought it would choke her.
