Water: the most valuable substance of all

One can endure only a few days without water. Although very often forgotten, providing the body with the fluids it needs is vital to life itself and to proper performance.

The value of hydration

Water represents 75% of body weight in infants and 55% in elderly, being essential for cellular homeostasis and life. Staying hydrated is crucial to the body’s ability to control temperature.

Adults are recommended to drink eight 8-ounce glasses of water each day, although it also depends on the person and each individual’s characteristics, including their diet, gender (since men generally sweat more than women), and body size (larger people are more prone to sweating than thinner people). Environmental conditions are also an influencing factor: the higher is the temperature, the higher is the risk of dehydrating.

The intensity of exercise and its duration affects as well the loss of fluid. Those who enjoy physical activity should drink before, during and after exercise. Dehydration can occur in every physical activity setting, even if the temperature is not high. Well-trained athletes need to be even extra-cautious. Their bodies are used to additional stress and perspire much more than less fit people, so they are able to stay cool more efficiently than most us.

Dehydration: know the signs

According to the Academy of Nutrition and Dietetics, we should be aware of a few signs of dehydration.

First, the colour of the morning’s first urine is an overall indicator of hydration status.

Also, early signs of dehydration are thirst, flushed skin, premature fatigue, increased body temperature, faster breathing and pulse rate, increased perception of effort and decreased exercise capacity.

Later signs include dizziness, increased weakness and laboured breathing with exercise.

Don’t wait to feel thirsty

For some of us, the practice of drinking water regularly can be a tedious task and is often forgotten. Oblivious to the fact that we are not taking the necessary amount of water, symptoms of dehydration may appear.

To make drinking water a habit is extremely important. Having a glass with water at the same time each day could facilitate the adoption of the routine. You may also carry a bottle of water on the morning commute or keep a cup of water on the desk. Waiting for thirst to replenish your body’s water levels may not be the best strategy: by the time you become thirsty, you have already lost two or more cups of water from your physical structure.

Sports are always a good choice as an extra curricular activity. According to a study from the University of Illinois, USA, the

better physical preparation, the better the intellectual development. Additionally, exercising has other benefits like fighting obesity, reducing the risk of cardiovascular diseases, increasing memory and attention, strengthening the muscle, bones and articulations, increasing self-esteem, diminishing anxiety, improve sociability, tolerance and discipline, helping with sleep and promoting good eating habits.

Family relationships: grandparents

Did you know that according to a study from the Institute of Aging from Boston, USA, a close relationship between grandparents and grandchildren is associated with a lesser risk of depression for both?  Psychological health becomes better as there is a stronger mutual emotional support.

Another study suggests that children with a close relationship with their grandparents have less emotional and behavioral problems. Grandparents are also a source of learning for children. They pass on pass on historical, cultural and scientific knowledge and help in the language development

Dyslexia

It is estimated that 1 in 10 people in the world have dyslexia, a genetic language disturb that interferes with the way the brain processes the written language. It causes problems in reading, as the child will have troubles recognizing words previously read or known. Dyslexia is not a sign of lack of intellectual capacity or laziness. A child may simply need more time to process all the information. It can be overcome with specialized therapy and other resources like adequate learning materials.

If you think your child may be dealing with dyslexia, contact us and we will help you booking an appointment with an appropriate specialist.
