Bend like a banana
“A side bend stretches the intercostal muscles between the ribs, making more space for inhalation,” according to the psychologist Suzy Reading, author of Self-Care for Winter, “and when we breathe better we feel more lively. Either seated or standing, breathe in and stretch one arm up overhead, forming a banana shape for your side body. Breathe out to lower your arm back down and come back to centre. Repeat five times on each arm.”
