“Sweat No More: The Surprising Role of Cold Blood in Beating the Heat wave

Ensure our well-being and functionality. While sweating is the body’s natural response to regulate temperature, there’s a lesser-known hero at play that aids in beating the heat wave: cold blood. Let’s delve into the In the midst of scorching heat waves, our bodies strive to maintain an optimal temperature to intriguing ways in which cold blood contributes to keeping us cool and comfortable even in the most sweltering conditions.

Cold Blood: A Natural Coolant

Maintaining Body Temperature Through Cold Circulation
Cold blood, often overlooked in discussions about thermoregulation, actually plays a significant role in helping us combat the rising temperatures. Our bodies are marvelously adaptive systems that utilize various mechanisms to stay within the optimal temperature range. One such mechanism involves the circulation of cold blood.

Cold Blood: A Natural Heat Sink

Heat absorption and redistribution beyond its role in circulation, cold blood acts as a natural heat sink. It absorbs excess heat generated by our internal processes, effectively preventing the body from reaching dangerously high temperatures. This process is akin to the way a sponge soaks up liquid – the cold blood absorbs heat and then redistributes it throughout the body for gradual dissipation.

Enhancing Endurance and Performance

Cold blood also offers unexpected benefits during heatwaves. The coolness of the blood helps maintain the functionality of cells and tissues, reducing the risk of overheating-induced fatigue and cellular damage. This is especially crucial for athletes and individuals engaging in physical activities outdoors. By preserving optimal cellular function, cold blood indirectly enhances endurance and overall performance.

Staying Cool: Nature's Masterstroke

The Symbiotic Dance of Sweat and Cold Blood
Sweating remains a crucial player in temperature regulation. However, when combined with the strategic circulation of cold blood, the body’s cooling mechanism becomes even more effective. As sweat forms on the skin’s surface, the adjacent cold blood vessels aid in its rapid evaporation. This synergy ensures that the cooling process is not only efficient but also consistently reliable.

Embracing the Cold-Blooded Advantage

In our quest to conquer the heatwave, it’s essential to recognize the role of cold blood as a silent yet powerful ally. From its involvement in maintaining circulation to acting as a heat sink and enhancing endurance, cold blood showcases nature’s brilliance in equipping us to thrive even in the hottest conditions. So, the next time you seek respite from the sweltering sun, remember that your cold blood is working diligently to keep you cool and comfortable.

The ever-increasing temperature has made life difficult for the people.

High Sunlight

Three continents – North America, Europe and Asia are in the grip of heat wave. In many countries, the temperature has reached more than 50 degree Celsius.


While India is currently experiencing a lack of heat, it is crucial to recognize the potential danger that heat waves can pose. According to the Government of India, a shocking statistic unveils that from 1990 to 2020, an astounding 25,983 lives were tragically claimed as a result of the relentless, scorching temperatures.


Seeing this figure of death, some questions must be arising in your mind. Questions like- what happens in our body in hot temperature that we cannot tolerate it, how our body works in heat, etc. Let’s know the answers to these questions…


First of all know how our body deals with heat i.e. how the body tolerates the heat…

When the temperature is high

The body keeps warm blood away from the internal organs to keep itself cool, and sends cold blood to these organs.

Proper circulation of blood is important in reaching the cold blood to the internal organs. The blood is redistributed from the core of the body to the periphery. During this, the heat comes out through the skin. This is called sweating.

Sweat comes out of the skin.

As this sweat dries, the body starts cooling down. Due to this, the blood temperature which was warm before the sweat dried up and was away from the internal organs, cools down and starts reaching back to these organs. Because of this, the internal organs become cold again.


Now know what happens in our body in excessive heat…

According to scientists, the body tolerates temperatures ranging from 35 to 37 degrees Celsius without any problem.

 At the same time, when the temperature starts to exceed 40 degree Celsius, then humans start having problems. According to research, it becomes difficult for humans to tolerate a temperature of 50 degree Celsius.


When the temperature is higher than our skin temperature (90 degree Celsius), the body gains more heat than it can release.


In dry weather, sweat evaporates effortlessly, allowing the body to stay cool effortlessly. However, in humid weather, sweat does not dry as quickly, making it challenging for the body to maintain a cool temperature.

Scientists say-

When the body gets too hot, we start sweating. This is a natural process of the human body. Through this the body tries to cool itself down so that it does not get harmed. When sweat comes out, it also gets dried by the hot air. But if there is a lot of humidity in the environment, then sweat comes out but does not dry. If the humidity is high then the heat is felt very much. On the other hand, the temperature may be high, but if there is no humidity then the heat is felt less. blood pressure decreases in summer


In the humidity, the body works hard to keep itself cool. This increases the heart rate and decreases blood pressure. This makes people dizzy. Whereas, when sweat comes out, the body gets dehydrated. That is, there is a lack of water in the body. Due to this, the level of blood also decreases and the blood pressure decreases.


High blood pressure patients, elderly, small children, thyroid patients, heart patients, kidney patients, pregnant women and diabetes patients are most affected by the high heat. If you are young, your body temperature can also increase by one or two degrees Celsius in high temperature. There is no danger from this but you may feel a little discomfort. But if the temperature rises too much i.e. along with unbearable heat the humidity level also increases, then the body temperature will also increase rapidly. In such a situation, you may be in trouble.

Organ failure due to excessive heat

Too much heat increases the risk of heat stroke. In this situation when the body is unable to control its temperature. In heat stroke, the body temperature rises rapidly and does not come down. The sweating mechanism of the body i.e. the sweating system fails. The body temperature may rise to 106°F or higher within 10 to 15 minutes. This can lead to organ failure.

A look at other heat hazards…


People often get tired quickly in very hot weather. Many times, people are unaware of their own actions. When our heart is not able to circulate blood in a normal flow, then in this situation there is a condition of unconsciousness. The problem of migraine and dehydration also increases in the rising heat.

Conclusion :


If someone has got heat stroke, then immediately follow the methods given below…


  • Place an ice pack or a cloth moistened with cold water on the head.


  • Place a towel soaked in cold water on the head, neck, armpits and groin.


  • Remove thick layers of clothing and allow air to circulate.


  • To cool down the body, sit in a cooler or fan.
