Digital blood pressure readings have two numbers – systolic blood pressure and diastolic blood pressure. The top number is your systolic blood pressure (the highest pressure when your heart beats and pushes blood around your body), and the bottom number is your diastolic blood pressure (the lowest pressure between heart beats). A blood pressure reading is usually these two numbers over each other – like 120/80.
I am trying to determine whether there is an association between time spent online and reported problems. I have divided my participants into two groups: the low user group and the high user group. I would like to see if there is a difference between the two groups. I used a Likert-Scale for my questionnaire, where the participants could either strongly disagree, disagree, neither agree nor disagree, agree, or strongly agree with a number of statements regarding various issues related to their Internet habits. Does anyone know what kind of statistical analysis I should use in order to determine whether there is an association or not?
Don’t get too excited. Turns out that dark chocolate (at least 50% to 70% cocoa) can give you a boost of a plant compound called flavanol. As with garlic, this antioxidant can raise your nitric oxide levels and widen blood vessels. That can make your blood pressure drop a notch. It goes without saying that a little bit of chocolate is all you need.
