Resort to the Cocoa Cure
Perhaps the most compelling way to warm up to winter: hot chocolate. The wintertime treat is rich in chemicals that enhance dopamine, a neurotransmitter than boosts mood. Compared to controls, volunteers who drank a cocoa drink in a recent study at Northumbria University in Britain performed better on cognitive tasks, had more mental stamina and were in better spirits. Credit goes to chemicals called flavonols—compounds in cocoa that have been found to increase cerebral blood flow and brain activity.
