It is important to stay hydrated in order to promote optimal functioning both in daily tasks and athletic success. Unsuitable hydration can bring about both dehydration and hyponatremia, which can cause symptoms like faintness, exhaustion, and poorer functioning.
For a distance that’s 5 miles or less, or 8km or less, you don’t need to worry much about staying hydrated. It’s alright to top up your liquid levels after your exercise session if you were out for half an hour to forty-five minutes, except when running outdoors in hot weather.
A lot of runners consume too many fluids, instead of having an inadequate intake. You can suffer from abdominal bloating or, even worse, hyponatremia if you over-consume alcoholic beverages and throw off your salt levels.
Lack of fluids while running can cause a headache afterwards, as well as various medical issues, and is not beneficial to your kidneys.
How Much You Should Drink
The recommendation for running and drinking is straightforward: Drink when you feel the need for it. Research has found that drinking whenever one is thirsty can aid in the prevention of underhydration, which can cause dehydration, and of overhydrating, a condition linked to having a low salt level in the blood as a result of an excessive amount of fluid being held in the body.
It is typically recommended that runners drink between 4 and 6 ounces of fluids every 20 minutes while exercising.
Athletes who complete their runs in less than 8 minutes per mile should consume 6 to 8 ounces of fluid every 20 minutes. For strenuous exercises that take up to 90 minutes or longer, it is important to include a sports beverage when rehydrating in order to replenish the body’s supply of sodium and other necessary minerals.
Determining Your Sweat Rate
The above guidelines are broad. It’s important to remember that everyone’s fluid needs vary. Some people sweat more than others.
To figure out how much fluid to consume during a jog or event, you need to be aware of your perspiration rate, which can range between 1 and 4 quarts each hour. Weigh yourself nude before a timed training run, and then again after.4 (You can drink during this run, but keep track of how much, and add this to your fluid needs calculation.) One pound of weight loss equals 1 pint of water loss.
Determine how much you perspire and use that information to figure out how much liquid you will need while running or competing. For instance, if you shed a pound while jogging for an hour, that is equivalent to sixteen ounces lost in an hour. If you consumed 12 ounces of liquid during your jog, you will need to replace a total of 28 ounces of fluid each hour. You must have 7 ounces of water or a sports drink every 15 minutes to switch this out.
Take note of the weather conditions on the day you undertake the exam and bear in mind you might have to change your intake if the weather is different. Conduct the sweat rate test on a different day to analyze the varying outcomes depending on the conditions.
Signs of Dehydration
Take note of any indications that you require additional fluids. Early symptoms include:1
- Thirst
- Dry mouth
- Feeling fatigued or sluggish
As dehydration progresses, symptoms can include:
- Headaches
- Muscle cramps
- Nausea
- Fatigue
What to Drink
There are options beyond plain water for rehydration. Some are only appropriate for longer, more intense runs.
Cold Water
Having cold water helps lower your body temperature, therefore slowing down sweating and the water loss that comes with it. Studies demonstrate that ingesting icy or even a frozen drink can prolong and increase your running performance. Additionally, the majority of people favor the taste of cold water, which may cause them to consume more hydration when it is cooled.
Sports Drinks
If you’re engaging in exercise that lasts longer than 90 minutes, particularly if it’s causing you to perspire, a wise decision is to start drinking electrolyte replacement sports drinks. Depending on what is going on, you may use a combination of water and sports drinks, or just go with the sports drinks for a time.
Electrolytes, the same components that can be found in table salt, are present in sports beverages, such as Gatorade and Powerade, in the form of sodium and potassium. When you are jogging, your body eliminates electrolytes through perspiration. You may have noticed the salty deposits on your running cap and sampled the saltiness of the sweat running along your face.
You must replenish electrolytes in order to maintain hydration levels and avoid muscle spasms. You need to replenish your energy and electrolytes after 90 minutes of activity and consuming a sports drink that provides carbohydrate calories and electrolytes would be beneficial.
Some athletes discover that it is sometimes more simplified to acquire their needed nutrition through drinks instead of solid sustenance, principally throughout the finally extended time of a lengthy run or competition. If you find that store-bought sports drinks do not fit your taste or the amount of sugar in them is too high, you can concoct your own.
Athletes who do not replenish their electrolytes sufficiently during lengthy runs or competitive events may be in danger of becoming overly hydrated. Hyponatremia, a deficiency in the concentration of sodium in the blood, can take place in athletes if they drink too much liquid and do not replenish salt eliminated via perspiration.
Flavored Water
If you find the taste of plain water unappealing, even when it is cold, you can make it more palatable by adding flavor so you can consume enough. Some water additives also include electrolytes, but many don’t. Be wary if you are running for a prolonged period of time, particularly if the temperature is high. A sports beverage might be necessary in addition to flavored water.
Coconut Water
Some runners enjoy drinking coconut water to stay hydrated and to aid in recovery. This drink has both the energy carbohydrates provide and the essential electrolytes such as potassium and magnesium. It has natural sugar that can give you an extra jolt of energy. Nevertheless, it is not as high in sodium as sports drinks.
Coffee
Recent studies have shown that having caffeine before an extensive race or lengthly training run can help with the benefits of completing it successfully and continuing with it. If you’re somebody who needs coffee in the morning, there’s no problem with having some before starting off your morning run.
Caffeine can lead to an increased urge to go to the bathroom. Remember that when undertaking your run, you should take bathroom availability into consideration. You do not need to be concerned that caffeine will cause dehydration. Not everyone is able to withstand coffee or other caffeinated beverages before going on a jog (it could cause indigestion), however if it is agreeable to your stomach then it’s alright to drink it.
Carbonated Drinks
The carbon dioxide in soda can cause problems with your digestion, leading to gas and stomach swelling. It is generally not advised during or before a run. Non-diet soda’s sugar content can lead to an increase in weight. If you are consuming soda, you are not consuming water or any other beverage with better nutritional value. Some marathoners enjoy a boost of energy and sugar craving with a soda during their endurance event. The sugar and caffeine provide energy to keep them going.
Prehydrating Between Intense Workouts and Races
If you plan on having an intense workout or taking part in a race within 12 hours of the last one, it is best to begin hydrating yourself about 4 hours prior to getting started.
To pre-hydrate, drink 5-7 milliliters of liquid for every kilogram of your body weight (2.2 pounds).
This would be approximately equal to a full tumbler of water for someone who weighs an average of 75 kilograms.
If you are worried about staying hydrated during exercise or a competition, it may be helpful to include a few salty snacks or beverages as part of your pre-hydration plan to help your body retain water.
It is not always necessary to drink water before physical activity if you haven’t exercised in more than 12 hours or if you are already adequately hydrated. It’s always a good idea to make sure you’re properly hydrated before you go for a run or compete in a competition.
How Much Should You Drink During Exercise?
The objective of drinking fluids during exercise or competitions is to stave off dehydration, which would detrimentally affect your capabilities or disposition. It is to be expected that a certain degree of dehydration will occur during lengthy physical activities; replenishing fluids after the workout is a must.
Taking this into consideration, the most recent conclusions on activities that cause you to perspire heavily is to just drink water when you start to feel parched.
The study that was conducted on this topic referred to consuming enough liquid to prevent being thirsty as “drinking a sufficient amount to prevent thirst”.
Running and Hydration – Here’s The Rule of Thumb
If you are searching for an exact sum of liquid so that you can arrange your hydration requirements first, here is the standard intake.
Generally, it is advised that sportspersons should attempt to consume between 0.4 to 0.8 liters or 8 to 16 oz every hour.
What Are Electrolytes?
When your body begins to produce more perspiration, it’s a good idea to incorporate electrolytes into your fluid intake in order to replace the minerals that your sweat expels.
You know how sweat is salty? It’s because you’re excreting these minerals.
Electrolytes are imperative for the human body to be in optimal condition, and are often lost through perspiration.
Electrolyte minerals can be identified by their ionic charge and comprise of sodium, calcium, magnesium, and potassium (certain lists include chloride and phosphorus too).
These minerals are necessary for proper functioning of cells, and they aid in maintaining the body’s pH balance. They are also vital for the proper working of nerves and muscles, including the heart.
As sweat rate increases, there is a larger amount of electrolytes being lost. There are several factors that influence sweat rate:
- Workout intensity
- Humidity (people sweat more in high humidity)
- Heat
- Genetics
- Gender (men in general tend to sweat more than women, although this is not always the case)
The quantity of perspiration that individuals release during exercises can vary dramatically, as well as the type of minerals present in their sweat. Some individuals perspire a larger amount of salt than others, which is why it is essential to be aware of the amount of sweat you produce.
Sports drinks that contain carbohydrates and sugar
Calories and sugars tend to be unnecessary for regular intensity workouts shorter than 90 minutes, so these sports drinks can be skipped ahead of, during, and after the workout activity.
But they are useful in providing easily absorbed calories if you are running for extended periods, during which you may need a carbohydrate-based fuel strategy.
A sports drink containing varying forms of sugar, such as glucose and fructose, along with electrolytes can be very beneficial and is an excellent item to have handy for rapid energy replenishment.
Every carbohydrate sports drink is not equal, so you should do some research and figure out which brand is best for you. For people with IBS, fructose can be difficult to digest, so it is important to find sports drinks that have sugars that their bodies can handle during strenuous activity.
Sports drinks are a convenient way to get the energy needed for long-distance running, as some runners cannot tolerate eating solid food (or even gels or chews) during a long-distance race.
Be sure to think in advance and figure out how many energy drinks, energy gels, candy, and/or meals you will need to sustain your fueling strategy. If you consume too much carbohydrate energy in one sitting, your body may have difficulty digesting this large quantity while you are active, leading to an upset stomach.
Risks Of Poor Hydration
It is essential to keep an eye on your hydration levels not only for maximum sporting results but also for your overall health and wellbeing!
Dehydration
The majority of individuals will not be deprived of fluids to the extent of risking their well-being, but many do demonstrate signs of dehydration such as weariness, muscle spasm, lightheadedness, perplexity, etc.
Dehydration that only causes a drop of 1-2% in body weight is considered ordinary during exercise activities, especially when participating in events that last a long time like a marathon. Your aim should be to try to counter slight dehydration and avert it from escalating into extreme dehydration which can lead to concerning issues such as convulsions.
Other symptoms of dehydration include:
- lightheadedness
- thirst
- fatigue and lack of energy / enthusiasm
- lack of need to use the bathroom
- dry mouth
- constipation
Hyponatremia
A factor that is rarely discussed in regards to hydration is hyponatremia; this is a condition in which someone drinks too much liquid, which is the antithesis of dehydration.
Hyponatremia is characterized by a decrease in blood sodium levels and results from the ingestion of too many low-sodium liquids for an extended period of time that surpasses the individual’s sweat rate.
The best indicator of hyponatremia is an increase in bodyweight over the course of exercise, which implies that too much liquid has been taken in.
Those who run at a low to moderate speed for extended periods and are thin in build are more liable to experience hyponatremia, but those who run at a faster pace are more in danger of dehydration.
In order to stop this from happening, drink an appropriate amount of liquids for your body’s demands when working out, and make sure to include salt and electrolytes when running for over a couple of hours.
