Overview
- Published in the British Journal of Nutrition, the analysis drew on San Diego State University’s Healthy Aging Survey of more than 400 Asian and White U.S. adults.
- Among Asian participants, higher intake of cold beverages in warmer months was associated with increased anxiety, more sleep disturbances and greater abdominal fullness.
- Among White participants, greater consumption of hot beverages in winter was associated with lower depression, improved sleep quality and fewer gastrointestinal complaints.
- Associations were strongest in individuals who frequently reported cold hands, with patterns varying across Asian subgroups including Chinese and Indian participants.
- The authors call for prospective and intervention studies before clinical guidance, and coverage notes echoes of traditional Chinese and Ayurvedic cautions about excessive cold consumption.
