Don’t grab that glass of water! It’s way too cold and it’s winter, so why drink it? Most of America is obsessed with any sort of cold beverage. Although you may be tempted to quench your thirst with a cold drink, and 79% of people agree with you that drinking ice cold water feels good, the question arises if it’s beneficial to your health. 

For me, I prefer to drink water at room temperature or warm. 虽然听起来很恶心, many scientists agree with this statement, claiming that warm water is more beneficial for your overall health. This includes very minuscule things such as your body's comfort to more serious issues like the well-being of your digestion or even breathing and swallowing. 

For those who still enjoy a refreshing glass of ice-cold water, is it worth it for that satisfying "ah" feeling?

哦，我的头!

Everyone has had headaches that occur without a clear cause 或者根本没有痕迹. 然而, what you have been sipping could be the trigger.      

A 2001 study conducted by the 圣人期刊 involving 669 women makes the connection between the intake of cold water and headaches. 通过这项研究，7.6% of women recorded having headaches after an intake of 150 milliliters of cold water. 然而, within this percentage, the majority of them were people who had migraines. 因此, those with migraines are twice as likely to experience headaches from the ingestion of cold water.

牙疼

It is a painful sensation when cold water hits your teeth and no one wants that. For those with pre-existing gum disease, 过度的斑块, 以及其他条件, drinking cold water worsens the immediate painful sensation of cold water. Because all of these conditions allow for nerves to be more sensitive, this doesn’t mix well with cold water.

鼻粘液增厚

的 国家医学图书馆's (国家卫生研究院) data supports that drinking colder water increases nasal mucus thickening. This is due to the cold water restricting blood vessels in the nose. 的 low blood flow in this area leads to a chain of events which decreases your immune system’s ability to fight off viruses, leading to an increase in nasal mucus.

血压升高

In the USA where almost half the adult population (119.9 million people according to the 疾病控制中心) have high blood pressure and this continues to be a rising issue, it is not the best idea to consume cold water.

一项2022年发布的研究 国家卫生研究院 found that drinking cold water temporarily increases blood pressure. Again, as cold water restricts blood vessels, it contributes to an increase in blood pressure.
    

While the temptation of a refreshing gulp of ice-cold water is undeniable, the potential health 缺点令人警醒. 另一方面， 还有更多的研究 supporting the other spectrum, drinking warm water.

失弛缓性救济

根据 约翰霍普金斯医学院, achalasia is defined as a “rare swallowing disorder that affects the esophagus.” Those with achalasia have lower esophagus (LES) that are unable to relax to pass food into the stomach. 

Yet, drinking cold water worsens these symptoms (Journal of Neruogastrology and Motility). 与此形成鲜明对比的是, the 国家卫生研究院 study of male achalasia patients found that drinking hot water relieves pressure in the LES. This ultimately lets the muscles there relax and allow food to pass through more easily.

舒缓消化

然而，健康 benefit  from warm water can apply to anyone, even those who do not suffer from achalasia. 的 国家卫生研究院’s 2016 study on the effects of drinking warm water discovers that it overall aids intestinal movement. 因此, making digestion a smoother process. Additionally, it is also recommended that those who have had surgeries, such as a 腹腔镜胆囊切除术, drink water at higher temperatures as this will put less stress on the intestinal area.

以毒攻毒

Even though it sounds contradictory, drinking hot or warm water will help your body on the sunniest days. 根据 a study conducted by the 渥太华大学, drinking warm water cools your body internally due to the increased production of sweat. Because sweating is a natural process to cool ourselves, drinking warm water helps with the production of sweat and rehydrates. 然而, drinking warm water is only effective if you haven’t started sweating yet and only on both hot and humid days. 

结论

It is beyond evident that the temperature of drinking water is more than a personal preference, but a matter of health and safety. Furthermore, comprehensive research sheds light on the impacts of this seemingly harmless practice. Regardless of what temperature of water you drink, please stay hydrated.
