We all know that caffeine is a stimulant; we reach for the tea or coffee first thing in the morning, but many of us keep reaching for it throughout the day. However, too much caffeine can play havoc on your body, keeping the adrenal system on alert over long periods and interrupting the flow of the hormone melatonin.
Melatonin is secreted by the pineal gland in the brain, and helps control body rhythms by telling our bodies when to sleep and when to wake. Research has shown that caffeinated coffee halves the body's levels of this sleep hormone. Heavy consumption - more than four cups a day - has been linked to ill health. So, drink less caffeine and after lunch switch to caffeine free drinks like herbal and rooibos teas. Rooibos, according to WebMD, has fifty times more antioxidants than green tea. These antioxidants are known to reduce free radicals in the body. It’s also rich in Vitamin C, low in tannins and may ease digestive problems.
