During the hottest months of the year, getting a good night's rest can become a challenge. For those seeking a natural solution, green tea is positioned as an effective alternative. This beverage, originally from Asia and now widespread throughout the world, contains antioxidants, caffeine, and amino acids that promote mental performance. Various studies have linked its regular consumption with improved memory and cognitive agility . Therefore, beyond its flavor, it provides real benefits to brain function.

Among its components is L-theanine , an amino acid that helps reduce stress and induce a state of relaxation without causing drowsiness during the day. This substance is linked to an increase in theta brain waves , which are linked to deep sleep . A study published in the journal Nutrients indicates that consuming low-caffeine green tea significantly improves sleep quality and reduces stress.

It also takes care of the heart and promotes weight loss.

Green tea not only has a positive impact on the mind: it also improves cardiovascular health . According to a review published in Nutrition Reviews , its bioactive compounds, such as catechins, may have protective effects on the circulatory system and metabolism. It also has a diuretic effect that combats fluid retention , which is common during the summer. Some studies also point to its ability to speed up metabolism and promote body fat reduction, especially when combined with regular exercise.

Unlike other types of tea, green tea is not fermented, allowing its antioxidant compounds to remain intact. This high-temperature drying process has been analyzed in the Journal of Nutrition, Health and Aging , where its consumption has been linked to improvements in working memory. It can be enjoyed hot, but it's also ideal cold for hot days. It's easily integrated into your daily routine, and its benefits increase over time .
