Do you know what are the dangers to the body due to this scorching heat that is still throbbing in Tamil Nadu?

In Tamil Nadu, the effect of heat has increased a lot in the last few days. As the temperature rises above 45 degrees, it becomes even more difficult to face the sun. This increased temperature has many adverse effects on our body.

To deal with extreme heat, our body activates its built-in cooling system of sweating, the heart beats faster, and blood vessels dilate so more blood can flow through them. The body may also be more susceptible to heat exhaustion and heat stress, which can cause symptoms such as dizziness, fatigue, nausea and muscle cramps.

When the temperature rises too high, overheating can cause multiple organ failure. When the scorching heat of summer pushes the mercury above 45°C (113°F), our bodies undergo a number of interesting changes. Extreme heat takes its toll on our physiology. In this post, we can know what changes will happen in our body due to this increase in temperature.

As the temperature rises, our body activates its built-in cooling system, which Sweating increases. When the temperature is above 45 degrees, sweat glands work overtime to release sweat, which evaporates on the skin, creating a cooling effect. Sweating helps regulate body temperature and prevent overheating, but it also causes water and electrolyte loss. It is important to replenish fluids and maintain proper hydration to avoid dehydration and related health problems.

vasodilation
In response to extreme heat, our blood vessels dilate in a process called vasodilation. When the temperature rises above 45 degrees, the blood vessels near the surface of the skin dilate, allowing more blood to flow through them. This expansion facilitates heat dissipation and helps regulate body temperature.

However, the dilation of the blood vessels can sometimes cause a drop in blood pressure, which can lead to dizziness or fainting. Staying hydrated and staying in a cool environment are essential to maintaining heart health during extreme heat.

increased heart rate
When we face temperature above 45 degree, our heart rate increases. The body perceives high temperatures as stressful and increases heart rate to deliver oxygen and nutrients to cells. The heart beats faster to maintain an adequate blood supply throughout the body, initiates cooling mechanisms, and maintains vital organ function. Individuals with pre-existing heart conditions should avoid strenuous physical activity during periods of extreme heat. Otherwise the risk of heart attack increases.

skin changes
Exposure to temperatures above 45°C can cause skin problems. The scorching heat can dry and irritate the skin, making it prone to sunburn. Ultraviolet (UV) radiation from the sun is more intense, increasing the risk of sunburn and long-term skin damage. To prevent harmful effects on the skin, it is important to protect skin from high sunlight exposure by using sunscreen, wearing appropriate clothing, and seeking shade.

heat exhaustion
Overheating can push the body’s temperature-regulating mechanisms to their limits, causing heat-related illnesses such as heat exhaustion and heat stroke. Heat exhaustion occurs when the body loses significant amounts of water and electrolytes through excessive sweating, resulting in symptoms such as dizziness, fatigue, nausea and muscle cramps.

Heat exhaustion can turn into heat stroke if not treated properly. Immediate medical attention is needed to prevent damage from heat stroke.
