Real coffee enthusiasts are usually of the view that there is never a wrong time to enjoy a cup of their favourite beverage or two. However, a new study shows that there is a right time of day to get the most benefit from your daily caffeine fix.
The United States Army has developed a computer algorithm that uses data from sleep patterns to make recommendations about coffee intake through the day so that the maximum amount of alertness can be achieved. The algorithm is so effective it can help an individual improve alertness by up to 64% without consuming any more caffeine than usual.
The researchers came to this conclusion by feeding their algorithm into a pre-existing computer model predicting how sleep deprivation, daily schedule and caffeine impact alertness at different times of the day.
The system can figure out safe, individualized caffeine-dosing solutions that result in a level of alertness that makes people more productive.
The new findings, published in the Journal of Sleep Research, will be used to enhance alertness for army workers.
Plus, the algorithm will be offered online within an existing online tool, 2B-Alert, to help users determine the best time to drink their coffee and will be of interest to many people, not least, shift workers, healthcare staff, sportsmen and students taking exams. There is also the possibility of a coffee app being developed at a future date.
Did you know? Five interesting facts about coffee
1 Coffee was discovered in Ethiopia in 800 AD by a shepherd called Kaldi
Kaldi noticed the effect caffeine had on his goats who appeared to ‘dance’ after eating coffee berries. A local monk then made a drink using the coffee berries and found it kept him awake at night. Eureka! The first cup of coffee was born.
2 There are two types of coffee beans: Arabica and Robusta.
Seventy percent of the coffee we consume is made from Arabica coffee beans. Robusta is popular in authentic Italian style coffee blends and has twice as much caffeine.
3 Coffee was originally a food
Coffee berries were mixed with fat to create a snack ball and also consumed as a wine made using the pulp from crushed coffee berries.
4 It is possible to overdose on coffee
However, a lethal dose of caffeine would require over 100 cups of coffee to be consumed.
5 Instant coffee was invented by George Washington
That is the chemist, George Constant Washington, who created Red E Coffee — the first branded instant coffee.
