Alcohol Drinking too much could increase your blood pressure. The opposite is true, when you drink occasionally and small quantities of certain drinks. Research evidence supports that moderate wine consumption could be beneficial for the health of your heart and arteries.

  • 2 drinks a day for men under 65 years
  • 1 drink a day for men above 65 years

Chronic consumption may render central nervous system unable to control blood vessel response to even minor blood flow fluctuations. Apart from this, direct effects of alcohol on cardiovascular system could also contribute to the onset of hypertension.

Dopamine then follows in to create a rewarding feeling every time you are engaging to the same pleasurable activity, urging you to repeat this activity over and over. It has been found that endorphins are released when small to moderate amounts of alcohol are consumed, boosting  in that way the addiction.
