As a blogger, I've recently delved into the effects of caffeine on premenstrual syndrome (PMS) symptoms. It turns out that consuming caffeine can actually exacerbate common PMS symptoms like irritability, anxiety, and sleep disturbances. This is because caffeine has stimulatory effects on the central nervous system, which can worsen these already-present symptoms. Moreover, caffeine can also lead to increased breast tenderness and bloating. In conclusion, it's important for those experiencing PMS to consider reducing their caffeine intake to potentially alleviate some of these uncomfortable symptoms.
