Water Continued...

It Will Help You Regulate Your Blood Pressure...
Why: In 2010, the American Red Cross discovered that when blood donors were given 16 ounces of water to drink before giving blood, there was a 20 percent drop in fainting after the procedure. That was an important finding for them, given that many of those who faint then chalk blood donation up as a bad experience and never return to give again.
It's not entirely clear what mechanism is at work. But the Red Cross was inspired to conduct a study after researchers at Vanderbilt University noticed that drinking water activated the parasympathetic nervous system -- related to the "fight or flight" system that makes you more alert, elevates blood pressure momentarily, and boosts energy. Fainting after donating blood is often connected to a drop in blood pressure, and they theorized that the water would counter that effect.
(Not drinking enough water on a regular basis can also raise blood pressure. That's because dehydration causes blood vessels to constrict as the body strives to conserve water that it loses through perspiration, urination, and breathing. When blood vessels constrict, however, the heart pumps harder, bringing blood pressure up.)
Water-drinking tip: Start your day with a glass of water for a simple energy boost that remedies any dehydration that may have occurred overnight. Keep a filled glass or bottle on your nightstand or an empty one next to the bathroom sink.
Until Monday - Keep thinking veggies and protein And drink lots of water!
