Uttarkashi Tunnel Rescue: Know what happens to the human body and brain without sunlight & limited oxygen

The Uttarkashi Tunnel Rescue operation has left Indians cheering after 41 workers were rescued after 17 days of sheer hard work and dedication. The unfortunate incident took place at Uttarakhand's Silkyari tunnel on Diwali, November 12. The labourers were trapped in the tunnel for over 400 hours, devoid of sunlight and oxygen. While the workers and their families are taking a sigh of relief, what are the implications of being trapped in a dark space for 400 hours? Let's find out.

What happens to the human body without sunlight?

Sunlight is the best source of Vitamin D and not getting sunlight for a prolonged period can affect you in many ways. While it is highly unlikely that an adult will die directly due to exposure to sunlight, however, it does affect your calcium levels which may lead to spasms of the larynx, causing suffocation. According to a report by the Archives of Internal Medicine, humans who were not exposed to the sun had a double risk of dying from heart disease. Sunlight Vitamin D absence can lead to depression, insomnia, and low immunity. Lack of Vitamin D also weakens the muscles leading to atrophy.

However, a diet rich in egg yolks, cheese, fatty fish, milk, juice, and cereal can help reduce the implications of no exposure to sunlight.

What happens to the body without proper oxygen supply?

Other than sunlight, the trapped workers were also devoid of oxygen. The claustrophobic environment and less oxygen in the tunnel space can lead to stress-induced anxiety, hypertension, and depression. According to a report by Financial Express, stress promotes the release of catecholamine hormones. The release of this hormone can further cause significant damage to the heart, brain and overall well-being. It also increases the risk of diabetes and hypertension.

“This release can cause significant damage, affecting vascular structures, the heart, brain, and overall psyche. The physical aspect is equally critical, with factors such as sleep deprivation and anxiety contributing to health issues. Many labourers may also suffer from comorbid conditions like hypertension and diabetes, requiring regular medication and a controlled diet,” a doctor informed the media outlet.

Though the government made sure to provide the workers with food, water, oxygen and other necessities, staying trapped in a dark tunnel for 17 days is no easy feat. The workers are currently being treated and we pray and hope for their fast recovery.
