Dehydration

By Flea - Be A Survivor

The weather this year has been warm in certain areas of the country where folks just aren’t used to that. I felt I should probably do a quick post on dehydration which can ruin your day very quickly if not addressed.

Put quite simple dehydration is losing more fluid and salts than you take in. As your body attempts to cool down using sweat, fluid is released and lost from your body. You need to replace that fluid by drinking on a regular basis or you will enter the early stages of dehydration.

You should drink whether you are thirsty or not when exerting yourself and sweating, by the time you “feel” thirst you are already in the beginning stages of dehydration.

Common causes of dehydration (not related to sweating and physical exertion) are:
Diarrhea (very serious in infants and young children).
Excessive vomiting
Fever
Inadequate intake of fluids (you don’t even have to be physically active)

The symptoms of dehydration are:
Dry mouth
Tiredness
Thirst
Not urinating or urinating very dark fouls smelling urine (water dilutes urea)
Weakness
Delirium
Not sweating (VERY serious if you should be sweating)

If you are physically exerting yourself and you stop sweating you need to get to a doctor right away, you are most likely entering into heat stroke and you will die if you don’t get medical attention promptly. Not sweating means your body has shut down its last and best defense against over heating and no has NO WAY of cooling you going forward.

The best way to ensure this never happens to you is to not let it get out of hand in the first place. Drink plenty of water everyday to ensure your body is well hydrated. Learn to recognize when you are over doing it and immediately stop what you are doing, find a cools spot and drink some fluids to get your temperature regulated and your body rehydrated.

Pay attention to those around you as well and ensure they monitor the intake of their own fluids so you don’t end up have to play doctor in a very serious medical emergency. Lastly always keep an eye on children as they can easily forget to stay hydrated if you don’t remind them.

...that is all.

  1. I always drink lots of water if I'm working outside in the head. Great post.

  2. Good post. Important topic.

    Here in the northwest corner of Wyoming we have very low humidity, which contributes to the potential for dehydration. A good rule of thumb that has served me well for many years... if I don't have the urge to urinate every two hours (approximately) I am not drinking sufficient quantities of liquids.

    Also be cautious because water doesn't replenish electrolytes and drinking only water can create other health issues.

  3. Hydration in hot weather
    I add 1/2 teaspoon Morton LiteSalt to my 2 liter backpack canteen
    page 118 Let's Eat Right by Adelle Davis
    Under normal circumstances, a healthy person runs little risk of deficiencies of sodium and chlorine. In extremely hot weather, however, so much salt can be lost through perspiration that death may occur.
    Death from salt deficiency occured during the construction of Boulder Dam and similiar projects. During the blistering summer of 1933 I corresponded with an engineer who was working on Parker Dam. Each letter contained some such note as, "We had a wonderful cook but he died yesterday of sunstroke." The symptoms of sunstroke are now recognized as caused largely by loss of salt through perspiration.
    A lack of salt causes symptoms varying in severity from mild lassitude, weariness, or hot-weather fatigue, common during heat waves, to heat cramp, heat exhaustion, and heatstroke, familiar to those who work in iron foundries, furnace or boiler rooms, and industrial plants such as steel or paper mills. Even persons who play tennis or take similar exercise during hot weather may suffer from heat stroke.
    Persons working in extremely hot weather are often advised to take a salt tablet with each drink of water.
    page 187 there are three nutrients - potassium, sodium and chlorine which we need in quite large amounts. Sodium and chlorine are supplied by tablet salt. Potassium is widely occuring in vegetables, fruits, whole grains, nuts and meats.

    Morton LiteSalt 11 oz about 99c
    1 oz = 6 teaspooons
    11 oz = 66 teaspoons= 76,560 mg sodium, and 89,760 mg potassium
    1/4 teaspoon serving
    290 mg sodium
    340 mg potassium
    40% iodine
    If you put one teaspoon Morton LiteSalt per gallon of water, an 8 oz serving will contain 72 mg Sodium, and 85 mg Potassium.
    8 oz of Gatorade
    contains 110 mg sodium, 30 mg potassium. (per Gatorade label.)

  4. When I was in the service...we were made to take salt tablets all the time when drilling. In San Antonio during the Summer at Lackland Air Force Base, so you know it was hot.

    Always good to remind folks to drink plenty of fluids during hot weather!

    Good stuff, some set for small children

    Hope it helps. Oh yeah Gatorade is not for small kids, for that, use Pedialyte. Gatorade is too harsh for kids. Feel free to check with your MD or Pediatrician.
