Bonus Drink: Tea
You know that coffee can give you a pep in your step, but there's another brew that can do it, too: tea. For one, consuming 68 mg of caffeine a day is associated with a reduced risk of depression, according to a meta-analysis published in the Australian & New Zealand Journal of Psychiatry. (For reference, a tall Earl Grey tea at Starbucks contains 40 mg of caffeine.) However, the drink does more than just buffer the moodiness—it can make you happier in the moment. Past research that looked into the impact of caffeine on mood also found that at least one cup of tea was necessary. Caffeine, the researchers explain, inhibits certain neurotransmitters that blunt brain activity and enhances other chemicals known to make you happy, like dopamine and serotonin. Coffee and tea drinkers report better cognitive functioning, including more focused performance, improved memory and lifted mood in the short-term.
