Puzzles are the perfect way to relax and calm our brains at the end of a busy day and help to encourage sleep, according to Dr. Meg Aroll, a Chartered Psychologist.

Poor quality sleep can lead to decreased productivity and higher stress levels.

The human brain has a cognitive capacity. In other words, there’s a limit to how many things we can focus on at once and this includes daily stressors and concerns," she said.

"That’s why occupying the mind before bed with a brainteaser can be an excellent way to switch off a buzzing brain."

"When the brainteaser is just tricky enough, it will use a large proportion of conscious cognitive capacity and help distract from worries that can keep us up at night."

She adds there are other benefits to doing puzzles before bed too.

Puzzles can also improve short-term memory, enhance dopamine levels, and lower blood pressure and heart rate.

“Brainteasers also improve cognitive function and memory and lead to a sense of mastery, all of which contribute to improved psychological well-being.”
