Taking too many tea breaks at work may actually make you more tired.
Researchers at the Lithuanian Sports University found taking a ten-minute break every hour actually led to more mental exhaustion.
The study of 18 men in their 20s also reported poorer concentration among those who stopped for regular breaks.
Researchers studied the impact of 10-minute breaks on work performance in a simulated office environment.
In the findings the researchers noted that regularly switching tasks can overstimulate the brain, leading to feelings of tiredness.
Scientists analysed blood tests and brain scans to examine the impact of the breaks on cognitive function, mood and motivation levels.
The research was set up to investigate how work hours and patterns impact on workers' productivity and overall well-being.
