1. Drink a glass of milk. It contains tryptophan, which as it is metabolized is converted to mood-boosting serotonin. Plus, its calcium, magnesium and potassium content may help keep blood pressure down.
2. Drink hot cocoa. Warm drinks raise your body temperature—a feeling we associate with comfort, so it triggers a similar response in our brains.
3. Order black tea instead of coffee. A study by University College London shows that drinking black tea four times a day for six weeks lowered the stress hormone cortisol after a stressful event.
4. Drink green tea is packed with theanine, which increases the brain’s output of relaxation-inducing alpha waves and reduces the output of tension-making beta waves.
5. Drink a glass of cold water, then go for a walk outside. The water gets your blood moving and the air invigorates by stimulating the endorphins that de-stress you.
