Ever heard someone say, 'If you're angry at someone, write them a letter and don't send it'? While that might seem like a waste of time, science reveals recording your feelings is great for clarifying your thoughts, solving problems more efficiently, relieving stress, and more. A team of psychologists recently hit on a neurological reason behind why this simple act might help us overcome some emotional distress.

The researchers studied brain scans of volunteers who recorded an emotional experience for 20 minutes a day for 4 sessions. They then compared the brain scans with volunteers who wrote down a neutral experience for the same amount of time. The brain scans of the first group showed neural activity in a part of the brain responsible for dampening strong emotional feelings, suggesting that the act of recording their experience calmed them. This same neural activity was absent in the volunteers who recorded a neutral experience.
