Water is essential for the human body. It supports vital functions such as regulation of body temperature, lubrication of joints, digestion, nutrient delivery to cells, and elimination of toxins and waste. Understanding the importance of hydration is necessary for maintaining health and preventing conditions such as dehydration. It’s also pertinent to note that water alone is not enough for hydration. The body also requires electrolytes like sodium and potassium to retain fluids. A lack of electrolytes can lead to the passing out of water through urine without any retention, making it impossible for the body to rehydrate. In these cases, hydration drinks become crucial for meeting the body’s hydration and electrolyte requirements. In this blog, we’ll explore key aspects of hydration, why hydration is more important than just drinking plain water, and who can benefit from hydration drinks.
What Happens When the Body Is Dehydrated
Dehydration occurs when there is significant loss of body fluids. Inadequate hydration can lead to extreme thirst, dry mouth, low urine output, fatigue, dizziness, and headaches. Extreme dehydration can cause electrolyte imbalance, muscle cramping, or impaired nerve signalling. It can also reduce the blood volume, leading to an increase in heart rate and low blood pressure.
Dehydration can occur for several reasons, such as inadequate water consumption, excessive water loss through sweating or diarrhoea, vomiting, or elevated ambient temperatures.
The most common symptoms people face during mild dehydration are:
- Headache
- Dizziness
- Poor appetite
- Decreased urine volume or dark coloured urine
- Muscle cramping
- Mood irritability
- Dry, flaky skin
When dehydration aggravates, symptoms may get complicated. These include:
- Low blood pressure
- Convulsion
- Constipation
- Rapid and deep breathing
- Rapid heart beat
10 Reasons Why Hydration is Important
The importance of hydration cannot be overemphasised. Replenishing body fluids is critical to maintaining good health.
1. Heat regulation:
Water helps maintain the body’s temperature, a process termed as thermoregulation. Chances of water loss are higher during exercise or exposure to hot-humid climate. A loss of fluids can lead to a lack of water in the body, increasing heat storage and body temperature. Adequate intake of water is advised to control the total body heat and prevent the risk of heatstroke or exhaustion.
2. Digestion:
Water is an important part of the saliva and gastric juices. Adequate hydration can help dilute the stomach acids, reducing the risk of bloating, acidity, or gastric reflux. Water also acts as an important component in the breakdown of food and nutrient absorption. It helps soften the stool and prevents constipation.
3. Joint health:
Water is an important component of the synovial fluids, which facilitate easy joint movement. Cartilages in the joints contain about 80% of water, cushioning the joint. A deficiency of water reduces the production of synovial fluid, making the joints lose their cushioning and movement uncomfortable.
4. Cellular function:
Water is present in the extra- and intracellular compartments. It transports nutrients to the cells, balances electrolytes, transfers waste material to the kidney for excretion, and manages many biochemical reactions occurring in the body. Thus, hydration is important for cellular function.
5. Heart health:
Water is present in the plasma, and is essential for maintaining the plasma or blood volume and blood pressure. Also, electrolytes like potassium are important for heart muscle contractions.
6. Electrolyte balance:
Electrolytes like sodium, potassium, and magnesium are lost through sweat, urine, faeces, and vomiting. Hydrating fluids contain all these electrolytes that are helpful in restoring and replenishing the body’s electrolytic balance.
7. Muscle function:
Hydration is important for efficient circulation as well as for the transport of oxygen and essential nutrients to the cells and tissues. Dehydration causes a shortage of nutrients and oxygen in the cells, leading to muscle damage, impaired performance, and muscle cramping.
8. Brain functioning:
Water affects the flow of oxygen to the brain tissues. Lack of water leads to poor transportation of fluids and nutrients, which ultimately causes fogginess and leads to bad mood, headaches, confusion, and tiredness.
9. Skin hydration:
Adequate water is important to enhance skin hydration. Poor water intake can lead to reduced blood flow to the skin, making it dry and flaky.
10. Flushes out toxins:
Hydration plays a crucial role in waste removal from the body. Water allows the kidneys to remove toxins by expelling waste. Higher intake of fluids flushes toxins out of the body, eliminating unwanted components that can prevent toxin accumulation and free radicals.
WHO CAN BENEFIT FROM A HYDRATION DRINK?
Hydration and electrolytes work synergistically. Hydration drinks can benefit fitness enthusiasts, gym goers and those working outdoors. They’re also beneficial for sportspersons and athletes engaging in intense endurance activities. Hydration drinks are usually formulated to help you restore energy levels and electrolytic balance after intense physical activity. These drinks replenish the fluid lost through sweat and precipitation in order to maintain hydration and overcome fatigue.
ROLE OF ELECTROLYTES IN HYDRATION
The main electrolytes that regulate the water movement within the body are sodium, potassium, chloride, calcium, and magnesium. They act as conductors and fluid regulators, helping water reach the cells. Water alone cannot replenish lost electrolytes. Sodium and chloride are the electrolytes present outside the cells, while potassium is present inside the cells. All the electrolytes are helpful in transmitting nerve impulses between the nerve cells. Without adequate electrolytes, nerve transmission is disturbed, which leads to muscle cramps and weakness. Sodium helps in the absorption of the fluid from the small intestine and maintains fluid volume. Potassium helps in muscle functions like contraction and relaxation, regulates heart function, and helps draw water inside the cells to maintain hydration and pH levels. Magnesium is important for muscle function, while calcium is helpful for bone health, muscle contraction, and nerve transmission.
How Steadfast Nutrition Supports Hydration Needs
Opting for an oral hydration solution is the most effective strategy for hydrating yourself. Steadfast Nutrition’s Steadlytes is one of the best supplements to maintain hydration. It provides the electrolytes: sodium, chloride, potassium, magnesium, and calcium along with vitamins B12 and C. An effervescent formulation, it is quickly absorbed by the body to provide instant hydration and replenish lost electrolytes. The vitamin C present acts as an antioxidant, boosting immunity while Vitamin B12 supports nerve health and maintains bone mineral density. The combination of electrolytes and vitamins recharges the body instantly and reduces chances of muscle cramps, fatigue, heat strokes or dehydration. This on-the-go rehydration supplement can be taken by anyone, including athletes, at any time of day.
Conclusion
It is crucial to understand the importance of hydration and electrolytes for the body. Sufficient hydration, mainly via water and electrolyte consumption, is crucial for various physiological functions. Unfortunately, we tend to miss out on hydration due to busy schedules and hectic lifestyles. It is important to set regular reminders to sip water and carry a water bottle to work. This helps maintain proper hydration and electrolyte status. Additionally, one must opt for hydrating liquids such as fresh lemon water or coconut water, as these provide vitamins and electrolytes for hydration which plain water does not.
