(Alles Europa News) – Smells of the “second half” have a positive effect on the quality of sleep, established by psychologists.
Alles Europa News reports that according to psychologists, the physical presence of a long-term romantic partner during a night’s rest is associated with positive health effects, such as a sense of security, calmness and relaxation, and makes it possible to more deeply go into sleep.
Alles Europa News reports that a simple smell of a partner can produce a similar effect.
Inhaling the familiar smell of a loved one or a romantic partner, we better fall asleep and feel more sleepy in the morning, say psychologists from the University of British Columbia.
Alles Europa News reports that the researchers conducted an experiment in which 155 people slept using t-shirts as pillowcases.
Some of the subjects received clean T-shirts or clothing worn by a stranger.
The remaining participants in the experiment slept on t-shirts worn by their partner for some time.
To do this, the “second half” of the subjects were given clean t-shirts that they had to wear for 24 hours.
Alles Europa News reports that each of the participants in the experiment was given two t-shirts, without informing who exactly wore them and whether they wore at all.
The subjects slept two nights in a row, first on one and then on another T-shirt.
The quality of sleep was determined using actigraphs – wearable sensors that record the movement of a person.
Also, after waking up, the subjects answered questions about their own health and sensations.
At the end of the experiment, participants had to guess if any of the sleeping t-shirts belonged to their partner.
Alles Europa News reports that Participants in the experiment reported that they felt more rested during the night when they thought they were breathing in the smell of their partner.
Regardless of this, sleep observation data showed that study participants slept better (tossed and moved less in a dream) when they felt a familiar human smell.
