Despite the allure of quenching thirst with a glass of ice-cold water on a scorching day, specialists in cardiology and public health caution that succumbing to this temptation can harbor unforeseen health risks.
They stress that indulging in chilled water frequently, particularly in warm climates, can pose serious threats to heart health and overall well-being.
Wakadaily learnt that, physicians highlighted that the habit of drinking cold water can potentially trigger severe heart complications and other health issues, such as sore throat, nasal congestion, and disrupted digestion. They noted that the consumption of extremely cold water may constrict blood vessels, leading to digestive disturbances and discomfort.
Dr. Akintunde Falola, a noted cardiologist, emphasized the negative impact of consuming cold water, especially following a meal, as it may contribute to increased mucus production in the respiratory tract and elevate the risk of inflammatory infections. He strongly advised against the habit of drinking chilled water due to its adverse effects on digestion and overall systemic health.
He noted , “Many adults, particularly those in tropical regions, are at risk of developing arrhythmia and cardiac arrest due to drinking chilled water. The cold temperature constricts blood vessels and forces the heart to work harder to maintain proper blood circulation.
“Consuming cold water has been linked to high blood pressure and an increased heart rate, gastrointestinal distress including indigestion and cramps. It can also weaken the immune system and decrease resistance to disease.”
Given these risks, the cardiologist advised adults to steer clear of cold water, especially when temperatures are high or during physical exertion.
Falola elaborated that cold water causes blood vessels to constrict, placing added strain on the heart to maintain circulation. This strain can potentially result in organ damage and a heightened risk of cardiac arrest, especially for individuals with existing heart issues.
Additionally, he pointed out that drinking chilled water may not only impact cardiovascular health but also weaken the immune system, making the body more vulnerable to illnesses.
“When the body is already struggling to maintain its core temperature, drinking cold water can overwhelm it and negatively impact its ability to fight off infection“When the body is already struggling to maintain its core temperature, drinking cold water can overwhelm it and negatively impact its ability to fight off infections and illnesses,” he cautioned.
Supporting his argument, Dr. Emmanuel Ifeajuna, a public health specialist, advised Nigerians to pay attention to their drinking habits. He emphasized the significance of staying hydrated by consuming room temperature or warm water, especially in hot weather.
“In these instances, it’s vital to ensure that the body’s core temperature remains regulated and stable, which can help to prevent unnecessary stress on the heart or other vital organs,” he stated.
The expert also cautioned individuals with existing heart conditions to be extra mindful of their fluid intake in hot weather.
He restated , “Those who are already at a higher risk of heart-related issues should exercise caution and avoid exposing themselves to any unnecessary strain on their hearts. Chilled water can also cause gastrointestinal distress, such as cramps, bloating, and indigestion.
“This is because cold water can slow down metabolism and interfere with the body’s ability to properly digest food, which can lead to digestive issues.”
Ifeajuna also mentioned that too much cold water intake may disrupt blood flow, which could ultimately result in numbness or tingling sensations in the arms and legs.
“People often think that drinking cold water will help cool them down in hot weather, but in reality, it can actually shock the system and put the body under unnecessary strain. It’s important to keep in mind that hydration and maintaining a healthy body temperature are key factors in preventing heat-related illnesses and heart-related problems,” he elaborated
The doctor also cautioned about the negative impact of consuming cold water on dental health, as it can lead to tooth sensitivity and difficulty in eating or drinking.
Additionally, a research study reported in the Journal of Physiology revealed that drinking cold water below 10°C during exercise in high temperatures of 34°C increased the occurrence of gastrointestinal issues compared to drinking water at a moderate temperature of 20°C.
The study findings indicated that cold water consumption resulted in higher instances of stomach cramps, nausea, and vomiting, with a prevalence rate of 50% in the cold water group, as opposed to 28% in the room temperature water group.
The researchers concluded that drinking cold water during physical activity in warm conditions could cause gastrointestinal distress and potentially hinder performance.
