“When the stomach is cold, all diseases can follow.”
Traditional Chinese Medicine proverb.
Many people reach for iced drinks without a second thought, especially during the summer. But cold beverages can subtly undermine your health.
Ice: A Recent Intrusion into Human Physiology
The habit of consuming iced beverages is less than 150 years old. In evolutionary terms, that is a blink of an eye. Human physiology has evolved to work with ambient or warm liquids, not icy shocks to the gut.
Health Implications of Cold Drinks
Our internal organs function best when kept warm. Cold beverages cause blood vessels to constrict, which slows digestion and impairs nutrient absorption. This can results in symptoms such as bloating, cramping, and constipation.
In Ayurveda and Chinese Medicine, digestion is said to be powered by internal heat, often referred to as “digestive fire” (Spleen/Stomach Yang). Cold drinks suppress this fire (Cold / Damp), which over time can weaken the immune system and reduce overall vitality.
Other common symptoms associated with cold drinks include:
- Phlegm and excess mucus
- Sense of heaviness
- Liver stress
- Headaches and migraines
- Chronic fatigue
So Why Do People Crave Icy Drinks?
In modern life, many of us run hot. Excess carbs, caffeine, and too much going on leave many of us wired, anxious, and overstimulated. Cold drinks offer a quick cooling sensation and temporary relief. The problem is, the relief is superficial and not truly restorative. Over time, the habit can contribute to chronic health problems.
Recommended Beverage Temperature
Opt for room temperature or warm beverages, especially before and after meals. Exceptions can be made during the hot summer months or after exercise, but choose cool, not cold. Adding mint leaves to your water can enhance flavor and gently cool the body without shocking the system. Personally, I keep a bottle of water in the refrigerator and a pitcher on the counter. In summer months, I mix the two for a moderately cool drink of water.
