Hello, Lykkers! As the sun blazes overhead and temperatures soar, the instinct to reach for a chilled drink becomes almost irresistible.


The sweltering heat of summer days can drive many to indulge in cold beverages, but have you ever wondered if these icy delights truly cool you down, or if they might be doing more harm than good?


Join us to unravel the mysteries behind hydration and staying cool in high temperatures!


The Cooling Illusion of Cold Drinks


Scientists explain that during extreme heat, the body naturally dilates its blood vessels, a process that helps regulate temperature by increasing blood flow to the skin. However, this physiological adjustment can leave some feeling sluggish, dizzy, or even queasy, leading to a craving for something cold—perhaps an iced drink or a slice of chilled watermelon.


Yet, the very act of consuming cold drinks can prompt blood vessels to constrict rapidly, which, in turn, can disrupt the digestive system. The sudden temperature shock may lead to abdominal discomfort, cramps, or even diarrhea. Moreover, the high sugar content found in many cold beverages—especially carbonated ones—can lead to excessive sugar intake, causing a spike in blood sugar levels and potentially accelerating calcium loss from the body. Over time, this could contribute to issues like osteoporosis.


Researchers advise that when the heat becomes oppressive, the best choices for hydration are cool water, mineral water, or purified water. For those seeking a bit more flavor, lightly brewed tea, salted water, or green bean soup can be excellent alternatives, helping to balance the body's fluids without the adverse effects of sugary drinks.


The Science of Smart Hydration


Proper hydration is critical in high temperatures, where the body's metabolic rate increases. However, experts caution against guzzling large amounts of water all at once. Consuming water in rapid, large quantities—such as downing an entire bottle in one go—can overwhelm the digestive system, leading to a reflexive increase in sweating, and paradoxically, further dehydration.


Instead, they recommend a more measured approach to hydration. Rather than waiting until thirst becomes unbearable, drink small amounts of water—about 200 to 300 milliliters—at regular intervals throughout the day. This gradual method is likened to the way farmers water crops: slow and steady, avoiding sudden, heavy downpours. In this way, the body remains adequately hydrated without triggering excessive sweating.


It's also important to replenish lost electrolytes, including sodium and water-soluble vitamins like B vitamins, which are excreted in sweat. A diet rich in fruits, and vegetables, and lightly salted water sipped from time to time can help maintain the necessary balance of nutrients.


Apart from hydration, there are other tips for us to keep cool but harmless.


Surviving the Heat Indoors


With many retreating to the cool comfort of air-conditioned rooms during heatwaves, scientists emphasize the importance of maintaining a balanced environment. Setting the air conditioner to around 26°C (78.8°F) ensures comfort without causing the body to react to extreme temperature differences.


Moreover, spending long hours in an air-conditioned space can lead to reduced circulation and joint discomfort. They suggest standing up and moving around every hour, perhaps engaging in light aerobic exercise to promote blood flow. Keeping joints and the lower back warm by adjusting clothing layers can prevent muscle stiffness and pain.


Nourishing the Body Wisely


High temperatures often diminish appetite, leading some to crave spicy, fried, or grilled foods in an attempt to stimulate hunger. However, those heavy, greasy meals will hurt our bodies during hot weather, as the digestive system is already taxed by the heat.


A light diet, rich in easily digestible foods like fish and shrimp, is recommended. Steamed, boiled, or stewed dishes are preferable, providing necessary hydration while being gentle on the stomach. Dark-colored vegetables and fruits, full of essential nutrients, should comprise a significant portion of the diet to replace those lost through sweat.


Navigating through the challenges of high temperatures involves more than just seeking immediate relief. Lykkers, with mindful hydration, and a smart choice of diet and environment, one can enjoy the summer heat without succumbing to its potential pitfalls. Stay cool, stay healthy, and let these tips guide your journey through the sunniest days!
