Historical background

The origins of séance are surprisingly mundane, given the mysterious atmosphere associated with the word. It comes from French séance, “seat, session”, from Old French seoir, “to sit”.

In French, as in English, the word came to be used specifically for a meeting of people to receive spiritualistic messages (a sense first recorded in English in 1845), but earlier in French and English the word had been used for meetings more generally.

One can do many things while seated. Certainly the second recorded use of the word in English, in 1803, does not promise the frisson of an encounter with the spirit world: “your séances . . . which I have a shrewd suspicion must be something dull.” Perhaps the writer was referring to the meetings of a legislature or learned society, which sometimes put attendees to sleep rather than into a trance.

2. A portable enclosed chair for one person, having poles in the front and rear and carried by two other people; a sedan chair.

In the 17th and 18th centuries, an enclosed chair carried by porters at the front and rear on two long poles passed through handles on the sides of the box.

1. Tending to avoid excitement or great activity and to be calm and relaxed.
2. To cause a person or animal to be very calm or go to sleep by giving a drug: "When I saw him after the accident, he was still in shock and was heavily sedated.
3. Etymology: From Latin sedatus, "composed, moderate, quiet, tranquil"; "to settle, to be calm" causative of sedere "to sit".

The verb meaning "to treat with sedatives" is a 1945 back-formation from the noun derivative of sedative.

Most sedatives (tranquillizers) can also promote sleep. Overdosage of a sedative medication can lead to dangerous respiratory depression (slowed breathing).

A drug that calms a patient down, easing agitation and permitting sleep. Sedatives generally work by modulating signals within the central nervous system.

These sedatives can dangerously depress important signals needed to maintain heart and lung function if they are misused or accidentally combined, as in the case of combining prescription sedatives with alcohol.

Many sedatives also have addictive potential. For these reasons, sedatives should be used under supervision, and only as needed.
