What Happens to Your Body When You Don't Drink Enough Water



About 60% of an adult's weight is water. The proportion depends on age, body composition and health, but water makes up most of your body. Water has several functions and is necessary to every physiological system.

You may be hungry

Not drinking enough liquids may promote daytime hunger. When dehydrated, your body may signal you to consume salty or starchy meals that retain water.

Headaches may occur

Dehydration is a leading cause of headaches. When your head hurts, drink water before taking a painkiller.

Constipation may occur

Fluid lubricates joints and tissues and aids digestion. Drinking too little liquids might impede stool excretion, causing discomfort.

You may tire more

Try water instead of caffeinated and sugary drinks to enhance your energy. This may enhance hydration and lessen the caffeine and sugar "hangover" an hour or two after drinking.

Heatstroke risk may rise

Heat cramps, weariness, and stroke are dehydration-related. These disorders may be associated with sports, but anybody may have their terrifying symptoms.

Your metabolism may slow down

Fluid intake has several benefits, including weight reduction. Drinking 17 ounces of water increased metabolism by 30%, according to the Journal of Clinical Endocrinology and Metabolism.

You may have trouble concentrating

Having trouble focusing? Your hydration may be the cause. Research shows that even minor dehydration may impair memory and concentration since your brain is 80% water.

Your heart rate may rise

If you have a greater heart rate when working, watching TV, or running, you may be dehydrated. Insufficient fluid intake makes your heart work harder to pump blood, raising your heart rate.
