Glass half empty?
Only half empty? Finish it off!
Water, like oxygen is essential for life. Without water, a human can survive just 3-5 days. Water serves many vital functions for health, including regulating the body’s temperature - so it is especially important to stay hydrated during the upcoming summer months. Dehydration is one of the most common preventable medical conditions in the world.
Alarmingly, up to 75% of Americans are chronically dehydrated. While many drink the recommended 8 servings of fluid each day, few realize that caffeinated and alcoholic beverages, and high-sodium foods actually remove water from our system which can cause a net loss of hydration.
Wondering if you’re fully hydrated? Look for these tell-tale signs of dehydration:
- Fatigue: A pair of recent studies found that people who are mildly dehydrated are much more likely to experience fatigue during moderate exercise and even when sedentary. Dehydration is said to be the Number 1 cause of mid-day fatigue!
- Thirst: If you feel thirsty, dehydration has already begun to set in. Just a 1-2% drop in hydration can trigger the thirst response. This can happen quickly, especially in intense work environments or when battling illness.
- Brain Fog, Irritability: Dehydration puts stress on our cognitive functioning. Increased anxiety and/or irritability as well as a dip in concentration or short-term memory can all be experienced as a result of dehydration.
- Kidney Stones: In a 1990 study of over 700 patients, chronic dehydration was shown to be a factor in about 20% of cases of kidney stones. More recently, in a five-year randomized trial, kidney stone sufferers were instructed to drink more water which resulted in a drop in the occurrence of stones.

- Hydration increases metabolism: One study found that drinking cold water helped boost healthy men and women’s metabolic rate by 30%. Researchers concluded that the body expends more energy heating the chilled water which resulted in a rise in metabolism.
- It can save your heart: Studies from a span over 6 years have shown that those who drank at least 5 glasses of water per day were 41% less likely to suffer from a heart attack than those who drank two or fewer glasses per day.
