Expatriate healthcare insurance customers may wish to monitor their caffeine intake.
"Small daily doses" of this drug can provide people with health benefits, but more sizable amounts causes harm, according to mindfulness based master practitioner of Neuro Linguistic Programming and author of Transforming Stress to Success Michelle Clemons said.
She noted that caffeine elevates the levels of stress hormone cortisol in the blood, pointing out two normal cups of coffee increase this by 30 per cent within an hour.
As individuals tend to drink this beverage when they are anxious and pressurised, this problem is exacerbated, the expert continued.
Ms Clemons claimed sleep patterns can be disturbed due to caffeine, as it has a half-life in the body of around six hours.
"As with all stimulants", people have to be careful about their consumption, the expert asserted.
However, research recently published in the Archives of Internal Medicine found that drinking caffeinated coffee is associated with a reduced risk of depression.
