If you have a history of troublesome sleep and are nervous about Glastonbury's loud nights camping outdoors, this handy trick might provide a restful night sleep, even during the warm weather.

The recent heatwave has left Brits restless in bed, effecting sleep patterns across the nation due to the stifling summer nights. According to the Met Office, we've seen 47% more sunshine since April, and the dehydration that followed might be the reason the UK is struggling to sleep - but electrolytes could help.

Spacegoods founder, Matthew Kelly, pointed out that dehydration and an electrolyte imbalance can be assumed to interfere with sleep. Whilst there is no clear, negative correlation between a lack of electrolytes and sleep, the functional beverages company suggest that a low level of hydration is associated with a lack of successful sleep.

A large study exploring hydration and sleep found that case studies which logged less than six or less hours sleep per night, showed lower levels of hydration than those who gained at least eight hours of sleep. The study, conducted in China and the US, highlights the importance of remaining hydrated, especially through warmer periods.
