Quoting from Rabbi Plotnik in Mishpacha:
Furthermore, the Gemara records how Rav Ami and Rav Asi would be careful to move out of the hot sun into the shade to avoid the blistering heat of Eretz Yisrael. Rashi understands that their motive was to avoid speaking ill of Eretz Yisrael. The Ri Migash interprets the Gemara slightly differently. He says that these Amoraim wanted to deepen their love of Eretz Yisrael by enjoying the feeling of relief from the shade of the Holy Land.
