Water and health: why drink enough
Chapter 1: The need for water for life: fundamental aspects
Water is the basis of life. It is from 55% to 78% of our body, depending on age, gender and physique. This precious element plays a decisive role in almost all physiological processes, supporting the functioning of cells, tissues and organs. Inadequate water consumption can lead to serious health consequences, from insignificant fatigue and ending with serious chronic diseases. Understanding the vital importance of water and its influence on various body systems is the first step towards optimizing health and well -being.
1.1 Water as a universal solvent and transport system:
Water is an excellent solvent, which makes it indispensable for transporting nutrients, hormones, enzymes and oxygen throughout the body. Blood, consisting mainly of water, transfers oxygen from lungs to cells and carbon dioxide back to the lungs for excretion. Lymph, another water -based liquid, transports the cells of the immune system and removes waste. Without enough water, these transport systems work less effectively, which leads to a slowdown in metabolism, a decrease in immunity and the accumulation of toxins.
- Transfer of nutrients: Water dissolves vitamins, minerals and amino acids from food, allowing them to be absorbed into the blood and deliver to the cells.
- Oxygen transport: Hemoglobin in red blood cells binds oxygen and transfers it throughout the body. Water maintains blood fluidity, ensuring the effective oxygen delivery.
- Removing waste: Water helps to remove metabolic waste, such as urea and creatinine, through the kidneys in the form of urine.
- Hormonal regulation: Many hormones, such as insulin and thyroid hormones, are transported in the blood and affect various processes in the body.
- Enzymatic activity: Water is necessary for many enzymatic reactions that catalyze biochemical processes in the body.
1.2 Water in thermoregulation:
The body uses water to maintain constant body temperature, which is extremely important for the optimal functioning of cells and enzymes. When we overheated, the sweat glands release sweat that evaporates from the surface of the skin, cooling us. This process requires a significant amount of water. The lack of water reduces the body’s ability to thermoregulation, which can lead to overheating, the thermal impact and other dangerous conditions, especially during physical exertion or in hot weather.
- Sweating: Evaporation of sweat from the surface of the skin takes heat in the body, reducing its temperature.
- Blood flow regulation: Blood tolerates heat from internal organs to the skin, where it can be scattered. Water provides sufficient blood volume for effective thermoregulation.
- Overheating prevention: Adequate hydration helps to prevent overheating during physical exercises, illness or stay in a hot environment.
- Maintaining stable temperature: Water has a high heat capacity, which means that it can absorb a large amount of heat without heating. This helps maintain stable body temperature.
1.3 Water in maintaining the health of joints and muscles:
Water is an important component of the synovial fluid, which lubricates the joints, reducing friction and providing smooth movement. Dehydration can lead to a decrease in the volume of synovial fluid, which increases the risk of joint pain, stiffness and injuries. In addition, water is necessary for muscle health, since it is involved in the processes of reduction and relaxation of muscles. The lack of water can lead to muscle cramps, fatigue and a decrease in strength.
- Synovial fluid: Water is a significant part of the synovial fluid, which lubricates the joints and ensures their smooth movement.
- Muscle contraction and relaxation: Water is involved in the electrolyte balance, which is necessary for the correct reduction and relaxation of muscles.
- Prevention of seizures: Dehydration can lead to an imbalance of electrolytes, which can cause muscle cramps.
- Maintenance of muscle elasticity: Water helps maintain elasticity and flexibility of muscles, which reduces the risk of injuries.
- Reduced inflammation: Adequate hydration can help reduce inflammation in the joints and muscles.
1.4 Water and kidney function:
The kidneys play a vital role in filtering blood, removal of waste and maintaining an electrolyte balance. For the effective performance of these functions, the kidneys are necessary for a sufficient amount of water. Dehydration can lead to a decrease in kidney function, which increases the risk of kidney stones, urinary tract infections and chronic kidney disease.
- Blood filtering: The kidneys filter blood, removing waste and toxins, which are then excreted in the urine.
- Electrolyte balance regulation: The kidneys help maintain the balance of electrolytes, such as sodium, potassium and calcium.
- Urine production: Water is the main component of urine, which is used to remove waste from the body.
- Prevention of the formation of kidney stones: Sufficient water consumption helps to dilute urine, which reduces the risk of kidney stones.
- Protection against urinary tract infections: Water helps to wash bacteria from urinary tract, reducing the risk of infections.
Chapter 2: Symptoms and consequences of dehydration
Dehydration can manifest itself with various symptoms that are often ignored or accepted for signs of other conditions. The recognition of these symptoms at an early stage allows you to take measures in a timely manner and avoid serious consequences. The severity of the symptoms of dehydration depends on the degree of fluid deficiency in the body.
