Frequently Asked Questions

Q. Why is fluid so important?

A. Water is essential to maintain blood volume, regulate body temperature and allow muscle contractions to take place. During exercise, the main way the body maintains optimal body temperature is by sweating.
Heat is removed from the body when beads of sweat on the skin evaporate, resulting in a loss of body fluid.
Sweat production, and therefore fluid loss, increases with a rise in ambient temperature and humidity, as well as with an increase in exercise intensity.
Drinking fluid during exercise/work in heat stressed environments is necessary to replace lost sweat. This action will reduce the risk of heat stress, maintain normal muscle function, and prevent performance decreases due to dehydration.

Q. What are some of the symptoms of being dehydrated?

A. Muscle fatigue, lower concentration levels, thirst, loss of appetite, dark coloured urine

 

Q. Why not just drink water?

A. It’s proven that water alone cannot sufficiently replace lost electrolytes. Pure water is absorbed slowly and cannot be retained by the body. During the first minute of consumption, the body absorbs HydraSafe™ significantly faster that it would water.
HydraSafe™ provides sodium to assist with replacing sodium lost in sweat and to assist in the prevention of cramping. HydraSafe™ may also contain carbohydrates which can assist in replacing carbohydrates used during extended periods of exercise/physical activity. The replenishment of these carbohydrates can assist with maintaining or improving energy and concentration levels.

 

Q. When, and how often, should I drink HydraSafe™?

A. During extending periods of time working
Working outside:

 

Q. What is Heat Stress?

A. Working in heat stress environments will create an increase in body heat which in turn increases the blood flow to the skin. The body is attempting to carry the heat to the skin where it can evaporate, subsequently causing the cooling effect to take place. The body releases heat through the skin via sweat which is the bodies cooling mechanism. By increasing its work rate, the heart will pump faster in order to carry the blood faster to the surface – thereby releasing the heat from the body as quickly as possible. The following factors will limit the cooling process from taking place:

If the above factors are present then the body begins to experience physiological heat stress with differing symptoms depending on the degree of stress.

 

Q. What are some of the consequences of Heat Stress?

A. An increase in the likelihood of accidents due to reduced concentration; slippery, sweaty palms; increase of discomfort of some personal protective gear, resulting in reduced protection and unsafe conditions. Some of these things can appear as follows:

 

Q. What is hyponatremia?

A. hyponatremia is an electrolyte disturbance (disturbance of the salts in the blood) in which the sodium concentration in the plasma is lower than normal (below 135 mmol/L).

 

Q. What are the causes of hyponatremia?

A. Whilst working in high temperatutes, sodium is lost through perspiration (sweat). A worker who only replaces the lost fluid with water could contribute to a decreased blood sodium concentration.

 

Q. What are the symptoms of hyponatremia?

A. Early warning signs are often subtle and may be similar to dehydration:

 

Q. How should hyponatremia be treated?

A. at the first sign of nausea, muscle cramps or disorientation, it is recommended that the individual consume a sodium replacement product / drink. The individual should then seek medical attention to ensure that they have appropriately replaced the electrolytes in their body.

 

Q. How can hyponatremia be prevented?

A. Prevention is always better than a cure.
The best way for an individual to avoid hyponatremia is to plan ahead. Tips and recommendations for planning include:

 

Q. How much fluid should I drink, and when should I drink it?

A. The amount of fluid, and the timing of drinks depend on the individual and the sport / work being undertaken.
