Surprisingly, however, is the level of dehydration. The majority of the people believe that they are drinking enough water simply because they no longer feel thirsty but in most instances the thirstiness is seen to be exhibited as the body is already in the dehydrating state. Mildly dehydrated state can affect silently energy, concentration, digestion, skin status, mood and so on. Such warning signs may lead to serious health problems in the long period of time. The human body provides us with rather sufficient signals when it needs water, however, it is only fair that sometimes we are not keen enough to pay much attention to them because we are too immersed in the day routine. These eleven are just plain and simple ways of knowing that an individual has not been taking enough water.
Dark-Colored Urine

Normal hydration causes normal urine to be referred to as pale yellow. The presence of a dark yellow or amber urine is a good sign that the body is using up a low amount of water and it needs more of it.
Reduced Vigor and perpetual Exhaustion.

This dehydration reduces the amount of the blood which is hard to provide with oxygen and nutrients. This tends to lead to laziness, weakness and overall weakness.
Dry or Chapped Lips

Lips is one of the initial localities where dehydration is experienced. The fact of constant dryness, dry cracking or dry peeling can be a sign that the body needs more water.
Frequent Headaches

The mildest level of dehydration may cause headaches or migraines. Fluid loss affects the blood flow to the brain causing pressure and pain.
Lightheadedness or Dizzy spells.

The lack of hydration can lead to the decline of the blood pressure level implying the feeling of dizziness, especially with the sudden stand.
Dry, Dull, or Tight Skin

The skin becomes unelastic and dull in case the amount of water in the body is not enough. It is either narrow, scabby or findingly bleak.
Bad Breath

Water helps in the elimination of bacteria in the mouth. When dehydrated, there is inhibition of the production of saliva and this creates the space that allows breeding odor-causing bacteria.
Joint Pain and Spasms in the Muscles.

Water assists in muscle working as well as the lubrication of joints. The deficiency of the fluids may lead to the fact that the muscles will cramp and the joints will ache or feel stiff.
Infrequent Urination

Failure to urinate in a number of hours is one of the common signs that the body is holding fluids. This is an absolute symptom of dehydration.
Lack of concentration or Brain fog

Dehydration affects the level of the cognitive performance. People lack attentiveness, responsiveness or lethargy in the face of lack of enough water.
Persistent Thirst

Continuous thirst is the first sign of the body. Once a couple of sips do not cause the thirst to decrease, it is an indication that its water loss has already taken place.
