The Relationship Between Hydration and Health

Hydration is essential to overall wellness; it allows the body to regulate its temperature, support healthy joints, prevent infections and provide essential nutrients to cells.

Water helps flush away waste products through urination, sweating and bowel movements – but what exactly is its relationship to health?

1. Increased Energy

Maintaining an adequate fluid intake can provide an energy boost. Your cells rely on water for their structure, and dehydration can sap your energy levels significantly. Rehydrating lost fluids by eating foods rich in water content (e.g. watermelons, lettuce and tomatoes) and replacing lost fluids is one way to keep yourself feeling refreshed and revitalized.

Water consumption can help improve concentration and memory. Studies have revealed that people can complete cognitively demanding tasks more effectively when adequately hydrated. When you feel thirsty, your brain signals for water but this alone should not be considered an accurate reflection of hydration status; thirst develops once your body is already dehydrated so the best way to monitor this status is looking at urine color (darker equals more dehydration).

Staying hydrated can help those leading active lifestyles perform at their highest potential on the job. Even losing 5% of body fluids can lead to a 30% decline in work capacity, so keeping yourself well hydrated in hot temperatures is especially vital in order to produce sweat that cools the skin and regulates core temperature.

Not only should one drink water regularly, but other forms of liquid can help contribute to optimal hydration: milk and fruit and vegetable juices as well as soup broths are excellent ways to stay properly hydrated; sugary beverages with caffeine may increase fluid losses by making you urinate more frequently, leading to dehydration. Eating meals rich in electrolytes like sodium, potassium, chloride can also aid in maintaining appropriate hydration; these electrolytes play a critical role in maintaining muscle, nerve and cardiac health.

2. Better Sleep

While hydration may seem more relevant for exercise or summer heat, it’s also essential for restful nights of restful sleep. Studies show a link between poor rest and dehydration; being dehydrated could make falling asleep harder at night while lack of rest increases risk for dehydration, creating an endless cycle.

Being well-hydrated can improve sleep by supporting healthy levels of vasopressin, a hormone which aids the body in retaining fluid. Studies have demonstrated the correlation between vasopressin production and length and quality of sleep, and headaches caused by dehydration; dehydration has even been reported among those diagnosed with sleep disorders such as obstructive sleep apnea.

Water can help ensure a peaceful night’s rest; aim for at least 11 cups for women and 16 for men each day, keeping a bottle or glass near your bed so you can drink as needed without disrupting sleep.

However, avoid drinking too many liquids just before bedtime as frequent bathroom visits can disrupt sleep. Instead, sip water throughout the day and avoid foods high in sodium (such as salty snacks) or caffeine which act as stimulants. If sweating heavily from physical activity or living in a hot environment is an issue for you, use breathable pajamas and fans to decrease overheating that could result in excessive fluid loss.

3. Less Pain

Water helps your fascia stay hydrated – the connective tissue that covers muscles, bones, and organs – by making it pliable and elastic; this improves movement while decreasing pain. Without enough hydration however, fascia stiffens up and becomes stiff and rigid, contributing to chronic back pain, arthritis, fibromyalgia or other joint or muscle problems.

Research on hydration and health has often focused on extreme cases: water intoxication or dehydration. But mild dehydration can also pose numerous health challenges, including fatigue, headaches, mood changes and difficulty thinking.

Experts typically recommend drinking eight 8-ounce glasses of water each day, although your water consumption depends on several unique factors like age and activity level. Older adults are especially at risk of dehydration as their thirst levels naturally decrease with age and they’re more likely to take medications that interfere with absorbing fluids by their bodies.

Not only should you drink enough water, but consuming healthy foods that contain plenty of fluids – like fruits, vegetables, and soups – is another important way to ensure optimal hydration. With regular physical activity combined with healthy eating habits and optimal hydration strategies in place, optimal hydration should be attained.

4. Lower Risk of Heat Stroke

Human bodies rely heavily on water for various bodily processes, from regulating cell temperature to flushing out waste products and lubricating joints. Staying hydrated allows your body to work optimally while also helping prevent various conditions like heat stroke. Staying hydrated both during and after exercise is especially essential to maintain muscle tone and decrease injury risks.

Dehydration significantly increases your risk of heat stroke and can even lead to potentially lethal conditions like hypothermia. Without enough fluid in your system, sweat cannot regulate temperature as efficiently. Furthermore, kidneys cannot excrete waste products as efficiently, leading to potentially deadly conditions like kidney failure.

To reduce the risk of heat stroke, drink plenty of water and strive to limit consumption of caffeinated drinks and those high in sodium content (which may actually dehydrate some people). Always read labels before purchasing beverages, such as energy drinks.

Researchers have also discovered that chronic dehydration could increase your risk of certain diseases in the future. A recent NIH study analyzed data from Atherosclerosis Risk in Communities (ARIC) study to examine whether hydration status was related to disease progression; their researchers discovered that those who consumed low amounts of fluids were more likely to experience high blood pressure, high cholesterol, and poor heart function due to chronic hypohydration triggering processes which damage cells and ultimately result in their breakdown.

To avoid dehydration, it’s a good idea to monitor the color of your urine to gauge how hydrated you are. When your urine has light yellow or clear hue, you are adequately hydrated; otherwise if its hue turns dark yellow or amber then more water should be consumed and you should also consume foods rich in hydration such as fruits and vegetables.

5. Better Memory

Water is one of the body’s primary elements and plays an integral part in almost every process, including cognitive functions. If we become dehydrated even slightly, our brain becomes less capable of processing information and memories which could have serious ramifications on mood and overall performance – hence why staying hydrated is so crucial!

Urine specific gravity or color is one way of measuring your level of hydration; you could also try tracking water intake via apps like Intake. One symptom of dehydration can be fatigue or difficulty focusing, so drinking enough fluids each day will improve memory recall and focus.

One study demonstrated that students were better at recalling word lists when properly hydrated compared to when not. Researchers theorize this may be due to water’s cushioning effect around delicate neural tissues, protecting against sudden shifts in temperature as well as acting as an absorber against concussions.

Another study took this concept one step further by showing that even slight dehydration significantly affected performance on tasks that required attention, memory and psychomotor skills (i.e. brain-muscle co-ordination). The effects were most prominent when dehydrated by less than 1-2% of total body weight loss – an accurate representation of daily fluid loss that may occur naturally during life.

Studies have also demonstrated the correlation between water consumption and mental clarity, and an optimal emotional state. Hydration benefits have been attributed mainly to its effects on hormone balance within the body – helping reduce cortisol production while creating an ideal emotional state.
