The origin of “Sleep tight”

The origin of the phrase “sleep tight” has its root attached with the old times, when there were no mattresses and people used to sleep on the beds made up of ropes. It was believed that when the ropes were pulled tight, one can sleep peacefully and deeply. From this fact of tightening the ropes and sleeping peacefully, the idiom “sleep tight” has been emerged.

Susan Bradford Eppes used the term for the first time in her diary “Through Some Eventful Years.” Rope beds had been replaced by box springs by this time. The idiom is frequently used accompanying “don’t let the bed bugs bite.” Many people think that that this term refers to folding your sheet firmly around your body to stop or to keep away the bed bugs attacking you. This idea is not intelligible but it is easy and acceptable in its rhyming pattern. There is a commendable genuine “sleep tight” nursery rhyme which can be helpful in order to understand and know the history of this idiom.  The rhyme is:

“ood night, sleep tight,

Don’t let the bedbugs bite,

Wake up bright,

In the morning light,

To do what’s right,

With all your might.”

However the poet is unknown. The word “tight” in the idiom portrays the connotative meaning “securely, safely, and properly.” This use of the word can be traced all the way back to Shakespeare’s period. As a result, telling someone to “sleep tight” means wishing them a restful night’s sleep.
