When the face becomes wet, the sleeping tendency is immediately removed. So when Rādhārāṇī was always weeping for Kṛṣṇa because of His separation, there was no chance of Her getting any sleep for Herself. In the prahlāda-saṁhitā Uddhava says, "The Supreme Personality of Godhead, Govinda, panic-stricken due to being pierced by the arrows of Cupid, is always thinking of you (the gopīs), and He is not even accepting His regular lunch. Nor is He getting any proper rest."
When the lover and beloved come together and enjoy one another by direct contact, this stage is called sambhoga. There is a statement in Padyāvalī as follows: "Kṛṣṇa embraced Śrīmatī Rādhārāṇī in such an expert manner that He appeared to be celebrating the dancing ceremony of the peacocks."
