Smells During Sleep May Shape Dreams
Pleasant Smells During Sleep Make for
Pleasant Dreams; Bad Odors Make for Bad Dreams,
Study Shows

A
bedroom that smells good may make for sweet dreams,
while a stinky sleep setting may lead to bad dreams.
That
news comes from a German study in which a positive
smell (roses), a negative smell (rotten eggs), or a
neutral smell wafted through a sleep lab while 15
healthy young women slept.
When
the women entered REM sleep, the researchers woke
them up and asked them what was on their minds just
before waking.
The
women described the dreams they'd been having and
rated how positive or negative those dreams had
been.
The
women reported more positive dreams when they had
smelled the rose scent during sleep, and more
negative dreams when they had smelled the scent of
rotten eggs during sleep.
The
type of scent didn't affect how long the dreams
lasted or how bizarre the dreams were.
It
would be interesting to see if pleasant scents
smelled during sleep affect nightmares, say the
researchers, who included Michael Schredl, PhD, of
the sleep laboratory at the Central Institute of
Mental Health in Mannheim, Germany.
Their findings were presented yesterday in Chicago
at the annual meeting of the American Academy of
Otolaryngology - Head and Neck Surgery.
