You skin is dry
Skin is the largest organ of the body. Without proper hydration, skin becomes dry and dull. By drinking more water, it’ll help flush out toxins and replenish your skins tissues hydrated and moisturized.
An obvious sign of dehydration is feeling thirsty. When we are dehydrated, our body borrows water and allocates it to the body parts that are in need of hydration. As a result, this causes us to become thirsty.
You have dark urine
If your urine is a darker yellow, you are likely to be dehydrated. Your kidneys have to work harder to keep urine concentrated to retain as much water as possible.
The saliva you’re body produces to clean and lubricate your mouth kills bacteria. If you’re not drinking enough water, you aren’t producing enough saliva to get rid of bacteria. This as a result causes bad breath.
When dehydrated, the tissue in our brain loses water, which results in temporary brain shrinkage. As this happens, our brain contracts from our skull, setting off the pain receptors, resulting in a headache. Dehydration also decreases blood volume which reduces blood flow and oxygen to the brain, leading to headaches.
Mood and alertness impaired
One reason dehydration impairs your ability to focus or respond normally is that certain processes in your body are being compromised. Water transports nutrients to the brain as well as flushes out harmful toxins for increased efficiency. Without enough water, this can lead to a lack of focus, moodiness, lethargy, and brain fog.
