The joy of coffee is that the caffeine can be useful for all hours of the day. It may not be the wisest choice for those who actually want to sleep, but numerous students around the globe use coffee as a staple to get through school.
When drinking coffee close to bedtime, the effect can result in poor quality and low quantity of sleep. Poor sleep can negatively impact the ability to focus on tasks of the day, and in many cases, this fatigue leads to drinking more coffee. Skapinker said this can create a cycle that is hard to break away from.
As Steiman said, caffeine is a stimulant and, in the short term, increases your heart rate and blood pressure. “Coffee has always been drunk for its caffeine and it always will be,” he said.
Coffee offers more than just the caffeine to keep students awake, it is also seen to enhance short-term memory. So for those who procrastinate and cram the night before a test, coffee can help you absorb and retain more information.
“[Coffee] can enhance physical endurance along with short-term, high-intensity physical performance,” Steiman added.
Coffee is seen as a saviour by many thanks to its high dose of caffeine, but remember that certain types of tea can help overcome sleepiness too.
Tea has a lower caffeine quantity compared to coffee, about one-third less than coffee. In figures, brewed coffee has about 80-179 milligrams of caffeine per 8oz cup, while black tea has only 43-50 milligrams per 8oz cup. Green teas have even less caffeine at around 25-45 milligrams per cup, but still rise above herbal tea, which contains no caffeine.
Prices of coffee and tea
With all the coffee shops around the world, coffee and tea are easier to come by and enjoy.
“Relative to other luxury items, especially luxury foods like wine and chocolate, coffee is fairly cheap,” said Steiman.
Coffee has evolved from simple brews, Americanos, and espressos, to flavoured lattes and Frappuccino’s. “There’s a wider range of coffee qualities and flavours than ever before,” said Steiman.
Many can find a regular brewed coffee for around $2, whereas specialty lattes, including those which are seasonal, cost around $5 a cup.
For coffee, the prices can widely vary whether you like plain coffee or flavoured and made with steamed milk. Tea is somewhat different because once you buy one in a coffee shop, you can usually ask to refill your cup with more hot water and save twice the amount of money.
Depending on the tea, one can get 50 grams of loose-leaf for around $7 to $20 for basic or rare tea. The tea can last for about 20-25 cups of tea depending on the personal preferences for the strength of flavour.
Tea bags are sometimes preferred due to their convenience. The average amount for 72 tea bags is $4.51 according to Statistics Canada. Buying teabags is the cheaper way to go, but you do sacrifice the freshness, taste, and a wide range of flavours that loose-leaf tea can offer.
