Dehydration And Heat Stroke

Every year we hear about or see on television the tragedy of professional and student-athletes die of dehydration while working in hot temperatures. Drink water before a workout. If you are dehydrated during training you reduce the body’s ability to transfer heat, while maintaining your job more difficult to heat, making it difficult for the body to meet the demands of aerobic.

Whether your training is strictly race or combination of exercises you want to consume cold drinks before your workout. Medicine & Science in Sports & Exercise released the results of a study in 2008. What they learned was the cyclists who drank cold beverages before and during their training nearly 12 minutes longer than those who drank hot drinks. By cooling the body down the heart does not work so hard, the body transfers heat more efficiently, and you can do a better workout.

Symptoms of severe dehydration:

First Extreme thirst

2. The lack of sweating

3. Little or no urination. Urine may be dark yellow

4. Very dry mouth and mucous membranes

5. More water can be dangerous, athletes must have drinks provide electrolytes and sodium or the risk of hyponatremia.

Hyponatremia

It is water intoxication, which can be fatal. Water intoxication is when the athlete has many symptoms such as dehydration, but they have swept all the sodium in their system. Sodium balance is necessary for proper transmission of nerve impulses and muscle function, and even a slight thinning of this concentration can cause problems. Studies have shown that high intensity athletes can lose up to 2 grams of salt per liter of sweat. The replacement of this at the event is crucial for the performance and safety.

Symptoms of hyponatremia:

Symptoms are similar to dehydration, nausea, dizziness, cotton mouth and pay attention.

Treatment of hyponatremia:

Consumption of sodium in sports drinks or eating salty foods.

Beverages other than water:

During your training more than just water, sports drink with sodium and electrolytes. Celery-based drinks and vegetable drinks are a good source of electrolytes and sodium.

Heat stroke of effort:

This is the most serious heat-related illnesses. Athletes are more prone to heat stroke effort. The difference between heat stroke and heat stress due stork is that athletes continue to sweat despite the core temperature.

The diagnosis of heat stroke or effort:

The core body temperature is 105 F with decreased mental status such as confusion, disorientation and clumsiness. If any of these symptoms are cooling the patent and emergency treatment is essential.

An ounce of prevention is better than cure.
