Couples who have long been in a close relationship can sense each other's emotions by smell. According to Innovanews.ru, scientists claim that it's not difficult for lovers to detect each other's mood by scent. They distinguish between the scents of fear, happiness, and sexual desire.
“The closer and warmer the relationship between people, the more likely they are to read each other's minds with their eyes closed,” said psychologist Denise Chen of Rice University.
Chen and colleagues studied 20 heterosexual couples who had been together for between one and seven years. Participants were asked to view various video clips that evoked feelings of fear, joy, or sexual arousal. The researchers collected sweat samples using hand swabs.
Next, the participants were given four different containers containing the sweat of their partner or a stranger of the opposite sex and asked to guess what the person was feeling. Almost two-thirds were able to guess the feelings they were feeling when smelling their partner's scent, and the longer they had been together, the more accurate their guesses were. For strangers, the accuracy rate was 50%.
As a reminder, researchers from the University of Michigan and the College of Houston previously determined the scent associated with age-related changes.
According to the portal Raut.ru, 340 men and women aged 45 to 70 participated in the experiment. Scientists collected sweat samples from both men and women and analyzed their chemical and biological composition. It was found that with the arrival of each new year, the human body produces increased levels of glucose and lactic acid bacteria.
It turns out that sweet odors are released during aging, and their production is regulated by sensory receptors in the skin. Experts identify carbon dioxide (CO2) as the first clearly defined odorant capable of prematurely altering physiology toward aging. It has also been established that people age faster and emit a specific odor if they consume fatty foods.
