Health effects of coffee and natural caffeine alternatives

Coffee consumption offers benefits such as increased alertness and concentration, but it can also cause side effects like nervousness, heart palpitations, or stomach issues in sensitive individuals. For those looking to reduce caffeine intake, natural alternatives include matcha and green tea. Matcha contains both caffeine and L-theanine, which may provide a more balanced boost, while green tea offers a milder caffeine dose and antioxidant properties.

Beyond energy levels, coffee can impact physical health in other ways. It may temporarily increase intraocular pressure, which is a consideration for individuals with glaucoma. Additionally, coffee can exacerbate symptoms of acid reflux, such as heartburn or throat irritation, depending on the individual and whether it is consumed on an empty stomach. It is also noted for its ability to stimulate bowel movements shortly after consumption.
