Causes of Excessive Sweating After Drinking Water

Experts suggest that people should focus on drinking water or any other liquid only when they are thirsty and not just because they want to. One may also need to cut down on the excess liquids if suffering from hyperhidrosis. Here are some of the major reasons for excessive sweating after drinking water.

Causes of Excessive Sweating After Drinking Water

Drinking Excess Water Increases Pressure on Kidneys

When you drink a lot of water, your kidneys are pressurized to work harder than before as they need to eliminate the extra load of fluid the body has been given. In order to do so, it not only makes you use the toilet more frequently but also makes you sweat excessively to balance out the fluid.

Brain Flushes Out Excess Water in Form of Sweat

On drinking too much water at any given point of time, a message is sent to the brain from the stomach that the body has become over hydrated and that the excess of water needs to be flushed out. The nervous system is then activated by the brain to excrete excess water through both urination and sweating. So when you sweat due to excess water consumption, the sweating lasts for a short while till the brain understands that the excess water has been eliminated from the body.

Hormonal Changes Cause Excessive Sweating

The body undergoes several hormonal changes during andropause and menopause and this too plays a major role in causing excessive sweating after drinking too much of water. Along with the sweating, the person can also experience night sweat and hot flashes all day long.

How to Prevent Excessive Sweating After Drinking Water?

In order to keep the body well hydrated, you must drink sufficient water every day. It is important to know that if you experience a lot of sweating after drinking water, it is no way injurious to your health and will have no ill-effects on the body. In most cases, the sweating is brief and not continuous. However, here are some easy ways to prevent excessive sweating after drinking water.

  • Instead of drinking a lot of water at one point of time, drink small amount of water at regular intervals. For example, if you are thirsty and want to drink water instead of drinking 3 glasses of water in one go, drink a glass of water every hour or half an hour to quench your thirst and keep the body hydrated. By doing this, you can also adjust the fluid loss from your body (in the form of sweat and urine) quite easily.
  • It is recommended not to drink too much coffee or any caffeinated product after water consumption as this can lead to excessive sweating. Once you have finished your caffeinated drink, wait for at least half an hour before drinking any water. This will prevent the sweating to a large extent.
  • If you wish to prevent excessive sweating, try not to immediately indulge in any kind of physical activity be it running, jogging, cycling or weight training after consuming water. Drink some water, wait for a few minutes and only then start your exercise regime or activity which you plan to do.
  • In order to prevent excessive sweating after water consumption, never drink loads of water after eating spicy food items. This plays a major role in causing sweating as your body gets heated up when you consume foods which are spicy and adds to the sweating rapidly.


A human being should never reduce his water intake as this can lead to several diseases and also prove to be fatal in some cases. However, if you are amongst those individuals who experience a lot of sweating after drinking water or any other liquid for that matter, then it is advisable to own the ways mentioned above to prevent this from happening. This will not only help you continue your regular water intake but also keep the body well hydrated without any excessive sweating.
