The tool is made with those who need to operate on high alert with minimal sleep in mind, such as soldiers and nurses.
, participants underwent several sleep deprivation and shift work scenarios. Researchers observed how their lack of sleep affected alertness and performance and how much caffeine influenced this. In some cases, study participants had to stay awake for up to 60 hours and their regular sleeping time was severely shortened. The research team then developed the Open Access tool 2B-Alert Web 2.0 based on these results.
Most people are not usually exposed to such unnatural sleeping patterns and a bad night's sleep can always be cured with some rest the following day. But this particular study was aimed at a different target group: it was conducted with US soldiers, whose job, more often than not, requires them to perform their best on little sleep. It also targets those who do shift work, such as nurses who also have to be alert and focused at all hours.
"For example, if you take someone who's been awake all night but needs to be as alert as possible between 9:00 and 17:00 and needs to consume as little caffeine as possible — when and how much caffeine should they consume?" asks Reifman."This is the kind of question 2B-Alert is meant to answer." As an Open Access tool, 2B-Alert is available to the public too - you just need to register using your email address.
