nocturia

Reader's　Digest 9月号の記事 "World of Medicine" からの引用です。

According to study published in Neurourology and Urodynamics, people who spend five or more hours a day watching TV and/or videos are significantly more likely to develop nocturia, the medical term for the need to urinate frequently at night. The condition, which affects some 50 million people in the United States, can disrupt sleep and lead to a greater risk of high blood pressure and cardiovascular disease.

"nocturia" の意味は説明文が後にあるので分かりますね。私も夜中にトイレに行きたくなることがありますが、今のところはあっても１回程度なので、まだ "nocturia" ではありません。
