1 | Turned body direction

Most people face someone who is talking if they are actually engaged and interested in the conversation at hand. Due to this, you should pay close attention to the direction of people's bodies when at a family gathering, says Boone Christianson, LMFT, a licensed marriage and family therapist based in Provo, Utah, and author of 101 Therapy Talks. 

According to Christianson, the main thing to look for is where someone's feet and torso are directed during a conversation. "If they are directed away from you, it may mean they are feeling discomfort or lack of interest in the interaction," he explains.

2 | Lack of eye contact

But someone doesn't have to turn their entire body away from you to indicate that they would like to distance themselves from a certain conversation. Instead, they might avoid eye contact with you, according to Heather Wilson, LCSW, a certified trauma professional who works in the behavioral healthcare industry and serves as the executive director at Epiphany Wellness.

"This could mean that the person is feeling shy or anxious about being part of the conversation, and so they are avoiding it altogether by not making direct eye contact," she explains. "It might also indicate that they are uncomfortable with what is being talked about or with certain people in the room."

3 | Clenched fists

This might be one of the more obvious body language signs of trouble, but it doesn't make it any less important to watch out for. Wilson says that someone is likely to clench their fists when they're anxious, stressed, or even preparing themselves for an upcoming confrontation.

"Pay close attention to the person's facial expressions and body language while they clench their fists as it may give clues into what emotions they are experiencing," she advises. "If you see [this], it is best to approach the person with care and understanding. Showing compassion and actively listening can go a long way in creating a safe and comfortable environment."

4 | Crossed arms

It can be hard for people to set healthy boundaries through clear communication with their family, according to clinical psychologistRayna Sanghvi, PhD. "This could be for many reasons; in some cultures expressing yourself may be seen as 'weak' or stigmatized," she says. "Or, folks have histories of invalidating interactions where they don't feel safe to express themselves."

As a result, many of us end up using some common non-verbal signals—like crossing our arms—to express ourselves during family conversations. Crossed arms usually indicate "distance and emotional discomfort," Sanghvi explains. Heather Browne, LMFT, a psychotherapist and relationship expert, tells Best Life it's important that we are responsive to what our family seems open and not open to discussing.

"Many families treat the individuals under an obligation mode where you must listen to Aunt Helen because she’s Aunt Helen," Browne explains. But that's not good practice. Instead, she advises you to pay attention when someone crosses their arms during a conversation: "You can always say, 'Would you like to talk more about this or would you prefer to stop? I want to be respectful.'"

5 | Facial tension

Someone's face can easily give them away—especially if there's tension at play. "Most facial muscle flexions that are sudden and short indicate some discomfort that could be anger, fear, frustration, or restraint," Christianson explains. According to the therapist, people's faces usually become tense when they're trying to suppress any of these negative emotions. "The holidays are often a time to walk on eggshells with people we know would not handle our feelings very well," he says.
