Practical application of spatial zones

Other people invade the intimate zone of a person for one of two reasons. First, another person may be a close relative, friend, or in the process of sexual courting. Secondly, the other person can be hostile, and then the invasion is considered as an attack. We are able to transfer when strangers are inside a personal or social zone, but the intrusion of an outsider into the intimate zone causes physiological changes in the human body. A person's heart rate increases, adrenaline is released, blood rushes to the brain and muscles - in short, a person is physically preparing to repel an attack or flight.
This means that if you, with the most friendly intentions, enlist an unfamiliar person, negative feelings towards you will arise in him. This will happen necessarily, even if your new acquaintance smiles and does everything not to offend you.

Women stand slightly closer together. They are more often face to face and more often touch each other than men who communicate with each other.

If you want others to feel comfortable in your society, always keep your distance. The closer your relationship with other people, the closer you can approach them. For example, a new employee may seem to be treated coldly by his colleagues, but they just keep him in the social zone until they get to know him better. Over time, this distance will decrease. Some will let the new colleague into the personal zone, and some, perhaps, even into the intimate.
