Are you the type of person to work non-stop throughout the day? In many American offices, and some other countries too, there is a culture the emphasizes continuous work. This means employees don’t stop for breaks, lunch, or even at normal quitting time. This happens due to a belief that this non-stop work ethic makes for a more productive workplace. However, is that true?

According to recent studies, taking breaks not only leads to greater productivity, but also better mental and physical wellbeing. An article in the Harvard Business Review by Zhanna Lyubykh and Duygu Biricik Gulseren titled, How to Take Better Breaks at Work, According to Research, highlights reasons why breaks are important.

Like batteries that need to be recharged, we all have a limited pool of physical and psychological resources. When our batteries run low, we feel depleted, exhausted, and stressed out.

Pushing through work when very little energy is left in the tank puts a strain on well-being and work performance. In extreme cases, nonstop work can lead to a negative spiral: A worker tries to finish tasks despite their depleted state, is unable to do them well and even makes mistakes, resulting in more work and even fewer resources left to tackle those same tasks. This means that the more we work, the less productive and more exhausted we can become. Think about reading the same line for the fifth time, for example, and still not absorbing it.

The good news is that taking breaks can help employees to recharge and short-circuit the negative spiral of exhaustion and decreasing productivity. 

Since breaks are valuable, what is the best way to take one? The authors provide a few suggestions, starting with break length:

A longer break does not necessarily equate to a better break. Disengaging from work only for a few minutes but on a regular basis (micro-breaks) can be sufficient for preventing exhaustion and boosting performance. For example, workers can take short breaks for snacking, stretching, or simply gazing out of the window. Further, timing of the break matters — shorter breaks are more effective in the morning, while longer breaks are more beneficial in the late afternoon. This is because fatigue worsens over the workday, and we need more break time in the afternoon to recharge.
