12 Reasons to increase Water

  • Fluid balance. Roughly 60 percent of the body is made of water. Drinking enough H2O maintains the body’s fluid balance, which helps transport nutrients in the body, regulate body temperature, digest food, and more.
     
  • Calorie control. Forget other diet tricks—drinking water could also help with weight loss. Numerous studies have found a connection between water consumption and losing a few pounds . The secret reason? Water simply helps people feel full, and as a result consume fewer calories.
     
  • Muscle fuel. Sweating at the gym causes muscles to lose water. And when the muscles don’t have enough water, they get tired . So for extra energy, try drinking water to push through that final set of squats.

  • Clearer skin. Certain toxins in the body can cause the skin to inflame, which results in clogged pores and acne . While science saying water makes the skin wrinkle free is contradictory, water does flush out these toxins and can reduce the risk of pimples.
     
  • Kidney function. Our kidneys process 200 quarts of blood daily, sifting out waste and transporting urine to the bladder. Yet, kidneys need  enough fluids to clear away what we don’t need in the body. Let’s drink to that!

  • Productivity boost. In order to really focus, a glass of water could help people concentrate and stay refreshed and alert.
     
  • Fatigue buster. Move over coffee—water can help fight those tired eyes too . One of the most common symptoms of dehydration is tiredness. Just another reason to go for the big gulp! (Not the 7-11 kind.)
     
  • Hangover help. If booze has got the best of you, help a hangover with a glass of water to hydrate the body and stop that pounding headache.
     
  • Pain prevention. A little water can really go a long way. Aching joints and muscle cramps and strains can all occur if the body is dehydrated .
     
  • Keep things flowing. Nobody wants to deal with digestion issues. Luckily, drinking enough water adds fluids to the colon which helps make things, ahem, move smoothly.
     
  • Sickness fighter. Water may help with decongestion and dehydration, helping the body bounce back when feeling under the weather. Just beware—drinking fluids hasn’t been scientifically proven to beat colds in one swoop, so don’t swap this for a trip to the doctor or other cold remedies.
     
  • Brain boost. A study in London found a link between students bringing water into an exam room and better grades, suggesting H2O promotes clearer thinking. While it’s unclear if drinking the water had anything to do with a better score, it doesn’t hurt to try it out!

July 11 – National Rainier Cherry Day

In 1952 at Washington State University, Harold Fogle created a new cherry by cross-breeding the Bing and Van cherry varieties.  This new cherry was named after Mount Rainier.  Now, each year on July 11, it is National Rainier Cherry Day.

Not only are cherries delicious they are so good for you!

Everyone’s favorite Bing cherry can significantly decrease concentrations of inflammatory biomarkers in the blood. And decreased biomarkers may reduce risk or modify the severity of inflammatory diseases such as arthritis, diabetes, cardiovascular disease, high blood pressure and cancer.

So that beautifully sweet, fat-free, cholesterol-free northwest cherry can benefit your body as well as your taste buds.

Study demonstrates that cherry consumption selectively reduced several biomarkers associated with inflammatory diseases.

October in National Spinal Health Month – The basics of Posture

Posture is the way you hold your body while standing, sitting, or performing tasks like lifting, bending, pulling, or reaching. If your posture is good, the bones of the spine — the vertebrae — are correctly aligned.

4 steps toward good posture

You can improve your posture — and head off back pain — by practicing some imagery and a few easy exercises.

  • Imagery. Think of a straight line passing through your body from ceiling to floor (your ears, shoulders, hips, knees, and ankles should be even and line up vertically). Now imagine that a strong cord attached to your breastbone is pulling your chest and rib cage upward, making you taller. Try to hold your pelvis level — don’t allow the lower back to sway. Think of stretching your head toward the ceiling, increasing the space between your rib cage and pelvis. Picture yourself as a ballerina or ice skater rather than a soldier at attention.
  • Shoulder blade squeeze. Sit up straight in a chair with your hands resting on your thighs. Keep your shoulders down and your chin level. Slowly draw your shoulders back and squeeze your shoulder blades together. Hold for a count of five; relax. Repeat three or four times.
  • Upper-body stretch. Stand facing a corner with your arms raised, hands flat against the walls, elbows at shoulder height. Place one foot ahead of the other. Bending your forward knee, exhale as you lean your body toward the corner. Keep your back straight and your chest and head up. You should feel a nice stretch across your chest. Hold this position for 20-30 seconds. Relax.
  • Arm-across-chest stretch. Raise your right arm to shoulder level in front of you and bend the arm at the elbow, keeping the forearm parallel to the floor. Grasp the right elbow with your left hand and gently pull it across your chest so that you feel a stretch in the upper arm and shoulder on the right side. Hold for 20 seconds; relax both arms. Repeat to the other side. Repeat three times on each side.

Practice these imagery and posture exercises throughout the day. You might try to find a good trigger to help you remember, such as doing one or more of them when you get up from your desk, or right before scheduled breaks and lunch. Soon it will become a habit.

Active body, active mind

The secret to a younger brain may lie in exercising your body

It is widely recognized that our physical fitness is reflected in our mental fitness, especially as we get older. How does being physically fit affect our aging brains? Neuroimaging studies, in which the activity of different parts of the brain can be visualized, have provided some clues. Until now, however, no study has directly linked brain activation with both mental and physical performance.

151023084456_1_540x360

As reported in the latest volume of the journal NeuroImage, an exciting new study led by Dr Hideaki Soya from the University of Tsukuba in Japan and his colleagues show, for the first time, the direct relationship between brain activity, brain function and physical fitness in a group of older Japanese men. They found that the fitter men performed better mentally than the less fit men, by using parts of their brains in the same way as in their youth.

As we age, we use different parts of our brain compared to our younger selves. For example, when young, we mainly use the left side of our prefrontal cortex (PFC) for mental tasks involving short term memory, understanding the meaning of words and the ability to recognize previously encountered events, objects, or people. When older, we tend to use the equivalent parts of our PFC on the right side of the brain for these tasks. The PFC is located in the very front of the brain, just behind the forehead. It has roles in executive function, memory, intelligence, language and vision.

If you are an aging woman, you will be wondering if these results can be applied to your female brain. Both aging sexes might also wonder whether increasing aerobic fitness later in life can increase mental fitness. The results aren’t in, but I’m heading off for a brisk walk just in case.
