Relieve your stress by identifying which hemisphere of your brain is being solicited. If you feel depressed or excessively emotional, your stress originates from the right hemisphere – the creative, emotive, holistic side. Switch to the more factual left side: do math, write, plan, organize. The emotional right hemisphere will calm down.
And if your overstuffed schedule is stressing you, it means that the left hemisphere is involved. Sing or play sports to switch to the right one.
