Which of the following is an effect of aromatherapy that can improve well-being?

The choice that indicates an effect of aromatherapy that can improve well-being is the relief of physical and emotional stress. Aromatherapy utilizes essential oils extracted from plants to promote relaxation and well-being, making it particularly effective for reducing stress and anxiety. The soothing properties of many essential oils, such as lavender and chamomile, can help calm the nervous system, leading to a decrease in physical tension and an uplift in emotional state. This ability to alleviate stress significantly contributes to overall well-being, as chronic stress can lead to various health issues, both physical and psychological.

In contrast, while enhancing decision-making skills, increasing attention span, and improving long-term memory are important cognitive functions, these effects are not the primary focus or well-supported outcomes of aromatherapy. Aromatherapy is more closely tied to emotional and physical relaxation rather than specific cognitive enhancements.
