Transcript of Dehydration
It's a state of losing more
fluid than your body is currently
Euhydration-normal body-water content
Hypohydration-increase in core body temperature and cardiovascular strain. This leads to a decrease in stroke volume and serum sodium levels.
Women are generally better hydrated than men. Women have a higher thermoregulatory threshold than men and, therefore, do not begin sweating until their core temperatures are higher. Causes of dehydration
Innability to drink fluids
Dehydration side effects
High blood pressure
10-15% body mass loss will bring on headache, tiredness, headache and general malaise (marking onset of disease)
20-30% of total body loss will likely result in death Fluids
Water is the basis for all body fluids and is involved in numerous vital metabolic processes. When we lose fluid, we also lose minerals such as calcium, potassium and sodium, which are electrolytes that help regulate the body’s fluid balance and metabolic processes. Just a two-to-five percent decrease in body fluid can reduce blood volume, decreasing oxygen delivery to muscles and organs when you need it most. Prolonged exercise, outdoor activities at elevated temperature or humidity, and occasional gastric imbalances are associated with loss of body fluid and dehydration. Decreased carbohydrate availability may also occur, resulting in low muscle glycogen levels.
The issue with this is any degree of exercise, even if be moderate can result in high fluid loss. Most people don’t recognize that their fluid loss is very low and at a dangerous level until it ‘s too late.
Gatorade and Advocare Rehydrate - help replenish fluids in the body faster by having ingredients in them that help you absorb the fluids into your body at a faster rate. These drinks help prevent cramping by providing calcium, magnesium and L-glutamine to support the contraction and relaxation phases of the muscles. With this being a huge factor in maintaining hydration. Specialists say that it is important after a workout to do about a half and half mixture of these plus water.
Some people will tell you that it is fine to consume beverages such as alcohol or caffeine, this is ill advised by many health professionals. Certified Dietitians and Physicians from the Mayo clinic state that alcohol and caffeine can act a diuretic, inhibiting the body’s ability to be able to retain water thus allowing the body to become a more dehydrated state. Populations at Risk
At risk due to poor body regulation systems and may not fully understand if they are in hydrated state or not. http://www.youcanbefit.com/hydra2.html Risks of Chronic dehyrdation
Health risks include: compromised cardiovascular function, renal impairment, and weakness
Also arthritis, muscular dystrophy, Diabetes References
