Abstract
Background: Attention deficit hyperactivity disorder (ADHD) is a neurodevelopmental condition with increasing prevalence of adult diagnoses in Denmark. ADHD is characterized by inattention, hyperactivity, and impulsiveness. Conventional treatment is primarily pharmacological. Many adults with ADHD face challenges in maintaining structure in daily life and have an increased risk of developing stress, anxiety, and depression. Winter bathing is gaining popularity and is associated with improvements in mood, sleep quality, and the ability to handle stress. Objectives: The aim of this study was to explore how winter bathing was experienced to affect the mental well-being of five adults diagnosed with ADHD. Methods: A qualitative research design was used, with participant observation and semi-structured interviews with five participants in April 2025. Additional data were obtained through interviews with a psychologist and an ADHD mentor. Empirical data were thematically analysed, followed by theoretical analysis. Results: Six themes were revealed: Mental calmness: peace of mind and relief from racing thoughts; Bodily awareness and connection to the body; Joy: sustained positivity; Nature: essential for motivation and general mind-body calmness; Coping with and managing everyday life better; and Winter bathing as a supplement or alternative to medication for anxiety, depression and ADHD. Conclusions: Five adults with ADHD experienced winter bathing as a meaningful and motivating non-pharmacological intervention that strengthened their mental well-being and quality of life. Winter bathing promoted general mind-body calmness, sustained joy, bodily connection, and mental coping, and was used as a supplement or alternative to medication. Nature emerged as a key motivational factor enhancing presence and well-being.
