tenseness

Worries and tenseness can lead to insomnia.

忧张会导致失眠。

Feel the body relax, feel the tenseness disappear, but do not fall asleep.

感觉体放松，感觉绷消失，但是不要睡着。

Their reticence and tenseness seemed to melt away as they petted the stray, and our sessions were relaxed and open.

他们摸拍这只无主的猫时，素日的缄张似乎融化了，疗程进行得既轻松，又坦率。
