Overheating, Dehydrated- Overexposure to Summer Heat

Our bodies are able to maintain our body temperature fairly well.  When circumstances arise where the body is no longer effectively cooling itself, a number of dangerous things begin to happen to us.

Sweating is a very effective mechanism that allows us to cool off.   However, heavy sweating is a sign of heat exhaustion.   Other signs are dizziness, headache, vomiting, muscle cramps, diarrhea, weakness, or an unquenchable thirst, numb and tingling hands and feet, muscle cramps, palpitations, breathlessness.  As you become dehydrated, you lose essential electrolytes such as sodium and potassium, which are critical for bodily functions.

If a person gets to a point where they are no longer sweating, with hot skin, and the body temperature rises above 41°, and experiences partial or complete loss of consciousness they are suffering Heat Stroke which would require immediate medical attention!!

To prevent Overheating and Dehydration:

Avoid sun exposure. Move some tasks indoors or into the shade. When that’s not possible, erect a temporary shelter. Take frequent breaks in a cool or well-ventilated area to get out of the sun and heat.

Don’t be afraid to sweat. Sweating is the body’s most effective cooling mechanism. The cooling occurs as sweat evaporates. In some cases a fan can be used to move cool air into a room and help keep body temperatures down.

Become acclimatized. Don’t take on strenuous activities too soon if you’re not accustomed to the heat. It can take six to seven days for the body to fully adapt (or acclimatize) to a new thermal environment. Ease into your tasks gradually, taking frequent breaks from the heat as needed. It is advisable to assign about half of the normal workload to new employees or those back from vacations or illnesses on the first day of work and gradually increase day by day.

Stay hydrated. Drink plenty of water – frequently (equivalent of about one litre every hour) – in hot weather conditions whether you feel thirsty or not to replace the fluid loss. Avoid consuming caffeine and alcohol, which can dehydrate you.  A great product to stay hydrated is LowOz™.  The average osmolality of  blood is 250. LowOz™ has been tested at an osmolality of 150.* Water is driven to areas of  higher osmolality. Since the drink will have a lower osmolality than the tissues, water will be absorbed into the tissue where it is needed.

Clothing. For protection from the sun and heat when working outside, cover up as much as possible with loose-fitting clothes made of a light fabric that “breathes”. When you work in the sun without a shirt or hat, the sun dries your sweat too quickly and prevents it from cooling the body. Clothes give sweat a chance to cool the body, and help protect the skin from the sun’s harmful rays.

Emergency Action Plan. An emergency plan should include procedures for providing affected workers with first aid and medical care. Workplaces where heat stress can occur should monitor conditions and ensure that workers get specified rest periods dependent on the measured heat levels. The Threshold Limit Values for Heat Stress and Strain, produced by the ACGIH (American Conference of Governmental Industrial Hygienists) offers guidelines to determine when the weather should have no effect on outdoor workers, when caution should be exercised and when work should be discontinued.


‘s electrolyte blend combines potassium, sodium, and magnesium in an optimal proportion to maintain water balance during exercise. The electrolyte blend helps you maintain your fluid balance during exercise so you can benefit from your workout and avoid exhaustion.*

LowOz™‘s energy blend combines slow metabolizing (fructose) and fast metabolizing carbohydrates (maltodextrin) and B vitamins to provide energy sources to sustain your workout.*

LowOz™‘s antioxidant blend includes vitamin C and an OPC blend (grape seed extract and maritime bark extract). This blend provides powerful flavonoids, catechins, and other antioxidant properties to support your body’s natural antioxidant defense mechanism.*

Research Brief
Osmolality is the measurement of solid particles in a liquid. Principles of chemistry teach us that a liquid will flow from a low osmolality environment to a high osmolality environment. This lowers the overall concentration of the solid particles and spreads out any associated charges of ions (electrolytes).

The average osmolality of blood is 250. LowOz™ has been tested at an osmolality of 150.* Water is driven to areas of higher osmolality. Since the drink will have a lower osmolality than the tissues, water will be absorbed into the tissue where it is needed. Research has shown the importance of proper hydration to help maintain optimal performance. In fact, dehydrating a muscle by as little as 3 percent can cause a 12 percent decrease in strength. Allowing water into the muscle tissue helps to balance the electrolytes, as well as providing an environment that may allow for further muscle growth and optimal recovery from exercise.

As we sweat, we lose water and important nutrients known as electrolytes. These electrolytes are necessary to regulate the flow of water across the cell membrane. Without the proper balance of electrolytes, our cells and tissues may become dehydrated. By combining potassium, sodium, and magnesium, LowOz™ is able to restore these electrolytes and balance out the fluids lost during exercise.
