Eustress typically has a positive impact and is characterized by energy, motivation, and perceived manageability, which can positively influence social relationships and emotions. A concise, evidence-based view:

• Core characteristic: It motivates and energizes, often improving focus and performance rather than overwhelming the individual. This makes it more likely to contribute to positive social interactions and constructive emotional experiences.

• Social relationships: When stress is experienced as a challenge rather than a threat, it can enhance engagement with others, collaboration, and resilience, which supports healthier social interactions.

• Emotional effects: Eustress is associated with positive emotions such as hope, excitement, and enthusiasm, rather than anxiety or helplessness. These emotional states support adaptive coping and well-being.

If you’re exploring this in a study or practical context, think of eustress as “challenge that energizes you and is within your coping capacity,” whereas distress would be the negative counterpart that typically hampers relationships and mood.
