Brain Power Improves Right After Drinking Water

//

Did you know that your brain functions better right after you drink water? If you need to give an important presentation, take a test, conduct a meeting soon or more, you might want to keep water nearby. My guess is that the finding could apply to all mammals, and not just humans. The benefit might even be more evident in other species. I’ve noticed that cats and dogs, for example, seem to exhibit a mini energy boost right after gulping down water.

Caroline Edmonds and Ben Jeffes of the University of East London examined whether drinking water improves performance in 6 to 7 year old children. The differences between the water and no water groups were significant, according to a paper that’s been accepted for publication in the journal Appetite.

They found that “even

under conditions of mild dehydration, not as a result of exercise,

intentional water deprivation or heat exposure” their test subjects’ “cognitive

performance can be improved by having a drink of water.”

The below fellow clearly doesn’t have a dehydration problem. He holds the world record for water drinking. Watch him down nearly a quart and a half of water in just 4 seconds.

Since this post touches on human health, I might as well also share with you the below tips from Harvard Health Publications’ Neck and Shoulder Pain Special Health Report. It gives important tips on how to protect your neck with exercises and good ergonomic posture at your desk.

“For example, you can take control of your body posture by setting up your chair, desk, and computer to encourage healthy neck and back positioning.

  • Set the monitor directly in front of you so you can see it without hanging your head down (monitor too low), tilting it back (monitor too high), or thrusting it forward (monitor too far away).
  • Use an upright paper holder so you don’t have to bend to read papers on your desk.
  • Set your keyboard at a height to help you maintain this upright position and not hunch up your shoulders or lean over to type.
  • Never hold the telephone between your head and shoulder. Use your hands, a headset model, or a speakerphone.
  • Keep your upper back and neck straight and your head positioned directly over your neck.
  • Use armrests to support your forearms.
  • Slide your buttocks far back in your chair.
  • Set your chair height so you can keep both feet flat on the ground.”
