The cooling effects of cold liquids are more likely explained by their rehydration effects. If heat does build up, the body will attempt to lose excess heat by transporting it away from the vital organs to the skin surface where it is transferred directly to our environment through convection and radiation. And large amounts of cold liquids will cause blood flow to slow, making heat transport less effective.Īs you can imagine, beverages with a high caloric content, such as soft drinks, will have a similar effect as ice cream and kick start our metabolism shortly after ingestion. But, this is only momentary and depends on the quantity and caloric content of the ingested liquid.Ī small amount of liquid will lose its cooling effect quite quickly as it gets warmed up by the surrounding organs. So ice cream is not the best option for cooling down, but what about cold beverages? The heat transfer between a cold beverage and the digestive system can directly influence temperature. Digesting calorie-rich food leads to an increase in body temperature. While it may seem logical that introducing something cold, like ice cream, into the stomach should help reduce temperature, its initial cooling effect is rapidly replaced by heat generated by digestive processes needed to break down the nutrients in ice cream. The heat this generates is beneficial when it’s cold, but when outside temperatures rise, we need to avoid overheating. It includes digestive processes involved in breaking down nutrients in food, the absorption and transportation of those nutrients to the cells, and their conversion into building blocks or energy necessary for physical activity. Metabolism is necessary to keep our bodies functioning correctly. We can do this because our bodies are constantly producing heat as a by-product of internal chemical processes (metabolism). Humans are warm-blooded or endotherms, which are scientific ways of saying we can control our body temperature independent of the environment. The process of maintaining an optimal body temperature is called thermoregulation, which involves a delicate balance between producing and losing heat. To test whether they do, we need to know a bit more about how the body controls temperature in different environments. While most of us agree ice cream and cold beverages are refreshing summer treats, do they actually help cool us down? One study has suggested that migraine sufferers may be more susceptible to these headaches.All over the world summer is synonymous with water activities, cold beverages and, of course, ice cream. The pain, through a quirk of our anatomy, is not felt so much in the mouth as it is “referred” to other areas of the face - behind the eyes and nose, in the forehead or elsewhere. No one is quite sure what causes the actual pain, but it is thought that a combination of direct stimulation of temperature-sensitive nerves plus the cold’s effects on blood vessels running along the roof of the mouth. Typical triggers include blended icy drinks, ice water and frozen treats such as ice cream, particularly when consumed rapidly on a warm day. Technically known as cold-stimulus headaches, an ice cream headache is set off when an unusually cold substance passes over the palate and back of the throat. Yet ice cream headache, or brain freeze, is more of an unpleasant quirk of our existence than a serious disease. Many people experience these sudden, excruciating and brief headaches after ingesting something cold. ![]()
