Coffee makes you happier, but only if you follow these rules
According to new research, drinking three or four cups of coffee during the day improves your mood and helps you cope with depression or winter sadness.
The research was requested by the Coffee Scientific Information Institute (ISIC). The researchers surveyed 5,000 adults from Finland, the United Kingdom, Italy, Germany and Poland. The study found that lifestyle and dietary choices can have a significant impact on mood, especially during the cold winter period.
The study found that nearly a third of adults experience a general feeling of sadness when the day gets shorter. But apparently this also has a solution. Consuming about 75 mg of caffeine - the equivalent of a cup of coffee - every four hours can lead to a marked improvement in mood.
20% of people interviewed by ISIC said they felt more relaxed after drinking a cup of coffee. 29% said they felt more energetic, while 21% said they had less difficulty concentrating. So about 70% had positive feedback.
How does coffee affect the brain?
Giuseppe Grosso, one of the researchers leading this study, explained specifically how coffee affects the brain.
There is evidence to show that micronutrients in coffee can pass from the blood to the brain, helping the body's neuroinflammatory response and the formation of new neurons in the brain.
"Polyphenols in coffee can cross the blood-brain barrier and exert anti-neuroinflammatory effects," Grosso said. "They may even promote neurogenesis, leading to a reduced risk of cognitive and emotional disturbances."
A further study, conducted by the Harvard School of Public Health, found that those who drank coffee typically had a lower risk of developing depression. Caffeine acts on the nervous system, stimulating the production of serotonin, noradreanaline and dopamine.
The study also found that the risk of suicide is 45% lower in those who drink 2-3 cups of coffee a day and 53% in those who drink 4 or more cups. On the other hand, no link was found between coffee that does not contain caffeine and the risk of suicide. This explains how caffeine is a key component that allows for true mood improvement.
However, it should be remembered that caffeine is a drug and taking too much can be deadly, so you need to pay attention to the side effects as well.
