From Wikipedia: There are three types of dehydration: hypotonic or hyponatremic (primarily a loss of electrolytes, sodium in particular), hypertonic or hypernatremic (primarily a loss of water), and isotonic or isonatremic (equal loss of water and electrolytes). In humans, the most commonly seen type of dehydration by far is isotonic (isonatraemic) dehydration which effectively equates with hypovolemia, but the distinction of isotonic from hypotonic or hypertonic dehydration may be important when treating people who become dehydrated. Physiologically, dehydration, despite the name, does not simply mean loss of water, as water and solutes (mainly sodium) are usually lost in roughly equal quantities to how they exist in blood plasma. In hypotonic dehydration, intravascular water shifts to the extravascular space, exaggerating intravascular volume depletion for a given amount of total body water loss. Neurological complications can occur in hypotonic and hypertonic states. The former can lead to seizures, while the latter can lead to osmotic cerebral edema upon rapid rehydration.
Dehydration is a serious thing. Now that we are rolling into summer and the gym is nice and warm between the sun and all the hard work you do in here it is important to remember that you need to be drinking water throughout the day. We recommend that you drink about 96 oz. of water a day. From our experience that is a good number to hit for water intake. However, this absolutely does not mean that you can sit down in the morning and chug 96 oz. of water before heading to work just so you can get it out of the way. You need to start drinking in the morning, have 32 oz. down before noon, 32 oz. down before 5pm, and another 32 oz down before putting your head down on the pillow.
The other piece of the hydration puzzle that commonly gets overlooked is eating right. We recommend that you stick with meath and vegetables, nuts and seeds, some fruit, little starch, and no sugar. Eat enough to not be hungry but don’t over stuff yourself. By doing this you can ensure that your body has enough nutrients to replace what gets expended through your workouts and just through living day to day.
Remember, your focus needs to be on eating to live (and train) not on living (and training) to eat.
