Doordarshan anchor faints during live weather broadcast: Some lesser-known causes of dehydration you must know

Discussing what happened, she mentioned in the video,”I had been feeling unwell for some time, and I thought drinking water would help. Normally, I never have water with me while reading the news, whether it’s a 10-minute segment or half an hour; I just don’t need it,”

“However, on that particular day, I gestured to the floor manager for a bottle of water, but no sound bytes were running at that moment as a general story was being covered. Unfortunately, this meant I couldn’t get the water I needed until a sound byte finally played. But, by then, it was too late and I fainted,” she continued.

Understanding the cause behind her fainting

Dr Palleti Siva Karthik Reddy MBBS, MD General Medicine and consultant physician, says, “The body tries to maintain its internal temperature by increasing blood circulation to the skin and sweating. Sweating, while essential for cooling, results in a significant loss of body water and salts (electrolytes). 

“If these fluids are not adequately replaced, the blood volume decreases, which makes the heart work harder to circulate blood. This increased cardiovascular strain can lead to symptoms like fatigue, dizziness, and fainting.”

In many parts of India, she says, high humidity accompanies the heat, which hampers the evaporation of sweat and reduces the body’s ability to cool itself effectively, increasing the risk of heat-related illnesses and dehydration.

Lesser-known factors that exacerbate dehydration and how to prevent them

While we are aware that dehydration can be caused due to sun exposure and lack of fluid intake, Dr Reddy enlightened us on other lesser-known causes of this problem that may surprise you:

Air conditioning

Constant exposure to air conditioning can dry out the ambient air, increasing respiratory water loss. Use a humidifier in air-conditioned rooms and increase water intake.

High protein diets

Metabolising protein requires more water, potentially leading to increased water loss. Ensure adequate hydration particularly if on a high-protein diet.

Caffeine and alcohol

Both substances have diuretic effects, promoting the excretion of water and salts from the body. Limit intake of these substances, especially in hot weather, and compensate with extra water.

Certain medications

Diuretics, antihistamines, and some psychiatric medications increase urine output or reduce salivation. Discuss medication side effects with a healthcare provider and adjust water intake as necessary.

Illnesses

Conditions like diarrhea or fever increase body water loss. Increase fluid intake during illness and consider oral rehydration solutions if necessary.

Intense physical activity

Vigorous exercise, especially in hot weather, increases sweat loss. Drink water and electrolyte-replacement beverages before, during, and after exercise.

Addressing dehydration requires an understanding of both environmental and personal factors. “Awareness and proactive hydration strategies are key, especially in climates prone to extreme heat. Providing education on the importance of hydration and recognising the early signs of dehydration can help prevent serious health issues,” suggests Dr Reddy.
