What fragrance promotes sleep?

Four smells help you fall asleep quickly.

First, lavender fragrance

Lavender (fragrance) has sedative effect and is also used in medical institutions and nursing facilities.

Lavender essential oil is the most famous one used to improve sleep. Sleeping lavender-scented quilts is more common than sleeping ordinary quilts, and the situation of rapid eye movement sleep and deep sleep is obviously increased. Let patients who often take sleeping pills smell lavender fragrance, improve their sleep state, avoid tossing and turning at night, avoid drowsiness during the day and be refreshed.

Second, cedar brain incense

Cedar brain can improve sleep as well as sleeping pills.

Let the subjects smell the scent of cedar brain from two hours to two hours before going to bed. The results show that the subjects' sleep time is shortened, the total sleep time is increased, and the number of waking up at night is also reduced. Especially, the time from lying down to falling asleep is 45% shorter than that of sleeping without smelling the fragrance of cedar brain.

Third, the aroma of coffee.

Coffee (fragrance) can be relaxed just by smelling its fragrance.

Coffee gives the impression of refreshing and dispelling drowsiness. But smelling it before going to bed can also help you fall asleep. After smelling the fragrance of coffee, observing the brain waves at the moment, we find that alpha brain waves, as an indicator of the relaxed state of the human body, appear frequently, and our mood can be calmed down.

The smells of Guatemalan coffee and blue mountain coffee can increase alpha brain waves. The other two coffees-Mandenin Coffee and Kona Coffee in Hawaii-will reduce alpha brain waves after smelling them. Both kinds of coffee will enhance the tension of the human body, so it is best to drink them in the morning.

Fourth, onion is fragrant.

Diallyl disulfide contained in onion has hypnotic effect, and folk therapy has its own reason to use it to help sleep.

A TV program in Japan once did an experiment to make kindergarten children who always can't sleep after a nap smell onions, and then investigate whether children can fall asleep because of it. As expected, children who take a nap in a room without onion smell can't sleep after tossing and turning; However, children who sleep in a room where chopped onions are put in advance will naturally fall asleep. But if the smell is too strong, the effect will be counterproductive.
