**Coming Soon** Sodium Sweat Monitoring
Monitoring Sodium Concentration of Sweat
Whenever you exercise, you lose fluids through sweat. Within sweat are small substances known as electrolytes which are essential for normal body function. One of these electrolytes is sodium (Found within table salt) which is required for controlling fluid balance in the body as well as having a major role in maintaining normal blood pressure and the normal function of the brain and muscles.
During exercise a very serious condition which many people are unaware of is hyponatremia. This is when blood sodium levels become abnormally low. This is often caused by an individual overhydrating which causes blood sodium levels to become diluted, resulting in exercise-induced hyponatremia. The symptoms of this vary depending on how much sodium is lost and how quickly. Symptoms can be mild or very severe and can include the following:
- Swollen Hands and Feet
- Extreme Fatigue
- Confusion and Disorientation
- Laboured or Difficulty Breathing
- Swelling and Brain Pressure
- Respiratory Arrest
Unfortunately, this condition is fairly common in some degree during marathons where runners who are not aware of it will just drink lots of water, thinking it is doing them good but fail to use any sports drinks to replace the electrolytes and will run into complications as a result. In 2007 a 22-year old man died following completing his first London Marathon and was found to be as a result of hyponatremia.
I have recently ordered a sodium monitor, which will allow me to monitor the concentration of sodium clients are losing during training and will then let us create a personalised hydration plan looking at how much sodium and fluids are needed to replace, at certain times in order to optimise performance and more importantly, train/compete safely without the risk of hyponatremia or dehydration.
More details of the sodium monitoring service will be posted once i receive the device. If you need my assistance with nutrition and hydration for training, get in touch to find out how i can help you achieve your goals!
