Referred to as the "warm water therapy," upon waking up in the morning, drink four glasses of warm water on an empty stomach.

It is recommended to drink warm water as soon as you wake up in the morning.

Is this method of water intake really beneficial for health?

◇Thick blood becomes thinner... Four positive changes

​

Drinking water on an empty stomach in the morning is beneficial in many ways. Morning fasting water intake helps to~

​

First, during sleep, approximately 500ml to 1L of fluid is released due to sweating and breathing.

It thins blood that has become more viscous.

Therefore, it reduces the risk of myocardial infarction and stroke, which commonly occur in the morning.

​

Second, it is good for waste elimination.

Drinking a glass of water immediately after waking up increases the volume of blood and lymph fluid, helping to smoothly eliminate waste products from the body.

​

Third, it promotes intestinal movement and helps with bowel movements.

In the morning, when I wake up, my intestines don't move and stay still.

When something is eaten, the stomach moves, causing the gastro-colic reflex.

A glass of water on an empty stomach in the morning helps promote bowel movements by aiding intestinal activity.

​

Fourth, it helps prevent chronic dehydration.

In the elderly, the secretion of antidiuretic hormone is often decreased, leading to a chronic state of dehydration.

While sleeping, hydration is not maintained, leading to worsening dehydration.

Drinking water immediately after waking up can prevent dehydration and promote metabolism and blood circulation.

​

Lukewarm water around 30 degrees Celsius is preferred.

​

What is the ideal temperature for water?

​

It is recommended to drink lukewarm water at around 30 degrees Celsius, slightly lower than body temperature, on an empty stomach in the morning.

Drinking cold water can excessively stimulate the autonomic nervous system, potentially causing arrhythmias and other heart problems.

Additionally, drinking cold water causes our bodies to use unnecessary energy to raise the body temperature back to normal.

Especially for the elderly or frail individuals, their basal metabolic rate decreases, so drinking cool water can help.

Body temperature decreases further, and gastrointestinal blood flow drops, which can lead to reduced secretion of digestive juices.

​

How much water should I drink?

​

There is no rule governing the amount of water to drink.

Some people insist on drinking four glasses, but there's no need to insist on drinking a lot of water.

Pay attention to your health condition and drink water accordingly.

Patients with end-stage renal failure or end-stage heart failure who drink too much water need dialysis.

Fluid retention in the body can lead to problems such as edema and difficulty breathing.

Diabetic patients tend to eat less because drinking a lot of water causes a feeling of fullness.

There may be risks such as hypoglycemia.

Patients with gastroesophageal reflux disease may experience worsening symptoms as the gastroesophageal junction opens frequently.

Drink an appropriate amount, more than one glass.

However, when drinking water, you should drink slowly rather than gulping it down quickly.
