Time runs faster when the heart speeds up.

When the activity of the sympathetic nervous system increases, that is, the heartbeat accelerates, people feel that time flies faster. These conclusions were made by scientists from the University of Liverpool during a study involving 67 people. During the experiment, volunteers wore heart rate sensors and changes in the electrical conductivity of the skin - it is affected by the activity of the sweat glands. People went about their normal business and each hour wrote down how fast or slow they thought the last 60 minutes had gone. It turned out that when the sympathetic nervous system was more active, it seemed to the volunteers that time was running 10% faster.
