ONCE YOU FEEL THE THIRST, YOU ARE ALREADY DEHYDRATED.
Water helps blood to circulate around the body efficiently and this helps to transport oxygen and nutrients to the muscles.
IN A DEHYDRATED STATE, IT WILL CAUSE :
- Blood to be thicker, requiring the heart to pump harder, resulting in a rise in blood pressure
- Enzymatic activity in the body to slow down, resulting in fatigue
- The body to produce more cholesterol and deposit it within cellular membranes in order to prevent water loss
Dehydration Signs and Symptoms
- Increased Thirst
- Urine is dark yellow and reduced in output
- Abdominal discomfort
- Muscle Cramps
- Deterioration in performance (sluggishness and lethargy)
- Dry eyes / mouth
If such issues are not addressed promptly, dehydration will escalate rapidly and may cause seizure, fainting spells, heat stroke or even coma.
However, this does not warrant the need to chug down bottles of water. Water intoxication can have detrimental effects to one's health.
How much to drink daily?
AT LEAST 8 GLASSES (2L) A DAY
Consistently drink water throughout the day, even when you are not thirsty. Increase intake if engaging in strenuous activities or working under a hot environment.
