It is known that drinking a glass of water immediately after waking up is good for health. While it is good to follow this practice, drinking cold water is not recommended. Trying to start the day lightly by doing so may actually put a burden on the body.

 

Drinking water immediately after waking up is beneficial. During sleep, our bodies become dehydrated. Internal hydration can be lost through sweat and respiration during sleep, amounting to up to 1 liter.

 

When blood becomes thick, the risk of developing cardiovascular diseases such as myocardial infarction or stroke increases. Drinking water immediately after waking up can lower blood viscosity and help prevent this. Drinking water on an empty stomach can also create a feeling of fullness, which may prevent overeating from the morning.

According to Dr. Brenda Davis's thesis from Virginia Tech University in the United States, people who drank two glasses of water 20 minutes before breakfast lost about 2 kg more than those who did not.

However, drinking cold water immediately after waking up is not recommended.

 

Suddenly pouring cold water on a body that has been sleeping all night can excessively stimulate the autonomic nervous system, increasing the risk of arrhythmia and other heart problems. When the body temperature drops suddenly due to cold water, our body may also consume unnecessary energy to maintain normal body temperature. Especially for the elderly, drinking cold water suddenly can cause body temperature to drop and reduce blood flow to the stomach, which may decrease the secretion of digestive juices.

 

Drinking water immediately after waking up is best with lukewarm water around 30°C, slightly below body temperature, rather than cold water stored in the refrigerator. Also, do not gulp down water quickly; drink slowly and leisurely. Patients with hypertension, a history of cerebral aneurysm, or cerebral hemorrhage should avoid drinking large amounts of water rapidly, as it can cause a sudden increase in blood flow to the brain. This may lead to issues such as rupture of brain blood vessels. It is recommended to sip slowly over about five minutes.
