Sports drinks may be useful if your activity is moderate to vigorous in intensity for more than 60 minutes.

While exercising, your body can lose a lot of water and fluid, as much as a litre or two in an hour. This is as a result of natural body functions like breathing, sweating, or making use of the bathroom.

Since we sweat and breathe more in the course of exercising, it is then very important for you to drink more water as well as stay hydrated.

The quantity of water you will drink is dependent on your size as well as sweat levels, fitness levels, environment such as hot or cold weather, and also the length and intensity of your workout.  Ensure to have available a bottle of water while exercising so you can sip from it regularly.

Disadvantages of drinking water during exercise

Overhydration by athletes is called exercise-associated hyponatremia. This happens when athletes drink even when they are not thirsty.

Drinking more than the required fluids during exercise can result to overwhelming of the body’s ability to remove water. The sodium content of blood is diluted to abnormally low levels. Cells absorb excess water, which can result to dangerous swelling in the brain.

Hyponatremia can lead to muscle cramps, nausea, vomiting, seizures, unconsciousness and, in few cases, it can lead to death.

When you drink excessive quantity of water, you may experience water poisoning, intoxication, or a disruption of brain function. It happens when there’s too much water in the cells (including brain cells), causing them to swell.

When the cells in the brain swell, they cause pressure in the brain. When this happens, you may experience things like confusion, drowsiness, and headaches. If this pressure enhances, it could result to conditions like hypertension (High Blood Pressure) and bradycardia (Low Heart Rate).

Sodium is the electrolyte affected most by overhydration, which results to a condition called hyponatremia. Sodium is an important element which assists in keeping the balance of fluids in and out of cells.

When the level drops as a result of high amount of water in the body, fluids get inside the cells. Then the cells swell, increasing your chances of having seizures, going into a coma, or even dying.

What Are the Signs That You’re Drinking Too Much Water?

One of the best ways to determine if you are drinking the adequate quantity of water is to check the color of your urine. It mostly ranges from pale yellow to tea-colored as a result of the combination of the pigment urochrome and the water level in your body. If the urine is mostly clear, it is a sure sign that you are drinking too much water in a short span.

Too many trips to the bathroom are a sign that you are relieving yourself more than usual. On average, you should urinate six to eight times a day. Going up to 10 times is normal for water-drinking high achievers or people who drink caffeine or alcohol on a regular basis.

Drinking water when you are not thirsty. For you to avoid drinking too much water, ensure you take it when your body needs it. The body can fight against dehydration by making you know when you need to drink some water.

Nausea or vomiting are also symptoms of overhydration and can look like those of dehydration. When you have too much quantity of water in the body, the kidneys can’t remove the excess liquid. It starts collecting in the body, which results to nausea, vomiting, and diarrhea.

Throbbing headaches all through the day. Headaches can be a sign for both hydration and dehydration. Excessive water in the body causes the body’s salt levels to go down as well as the cells to swell. This swelling makes them to grow in size, and those in the brain press against the skull. This pressure causes a throbbing headache and may result to brain impairment as well as trouble breathing.

Discoloration of the hands, feet, and lips as well as swelling can be caused by overhydration. And when the cells swell, the skin will also swell.

When the electrolyte levels drop as a result of too much drinking of water, your body balance goes down. Low electrolyte levels in the body can result to muscle spasms and cramping.

Drinking too much water makes your kidneys to work too hard to remove the excess amount. This creates a hormone reaction that makes you feel stressed and fatigued. If you are unable to get out of bed after drinking too much water, it is because of the fact that your kidneys are overworking.


You now understand why taking enough water during exercise is important. Ensure you always stay hydrated while exercising to avoid dehydration.

If you are taking water, make sure you don’t take it in excess because overhydration too can result to different problems.

To be on the safer side, while you take water, make sure it is not in excess and it is not below the adequate quantity your body will need to stay hydrated. And also ensure you don’t take the fluids your body don’t need when you are exercising.
