Coffee may temporarily improve mood and alertness in people who
tolerate caffeine well, but it should not be considered a treatment for depression or other mental health conditions.
4. Coffee Can Improve Exercise Performance
Caffeine is one of the most extensively studied substances in sports nutrition.
It can reduce perceived effort and improve performance during certain endurance and high-intensity activities.
That is why caffeine appears in many pre-workout products and sports supplements.
The effect varies considerably from person to person, and not everyone performs better after caffeine.
People who are very sensitive to caffeine may instead experience shakiness, rapid heartbeat,
anxiety, or stomach discomfort.
5. Coffee May Slightly Increase Metabolic Rate
Caffeine can temporarily increase energy expenditure and stimulate the nervous system.
However, this effect is modest and should not be interpreted as meaning coffee causes meaningful long-term weight loss.
Adding large amounts of sugar, cream, flavored syrups, or whipped toppings can also turn an otherwise low-calorie beverage into a high-calorie drink.
