Drowsiness and lack of sleep in climate change

The human brain is particularly sensitive to heat. According to scientists studying the impact of climate change on health, higher temperatures cause the central thermostat of the body and activate stress reactions.

Our bodies give priority to cooling to everything else in extreme heat, which means that less oxygen and blood flow reach the brain and muscles. That is why we feel sluggish, foggy and non -mobilized during the hot days.

Such changes resulting from heat are more noticeable in temperate areas, with Pakistan being one of them.

It is not that Karachi afternoons have been stretched in infinity. It is the heat and humidity that make it difficult to move, to operate, to want something else than a nap.

Researchers are increasingly considering how increasing global temperatures affect sleep standards and contribute to wider health complications.

“The growing temperatures caused by climate change and urbanization are a planetary threat to human sleep and therefore health, performance and prosperity,” said the 2024 review published in Sleep Medicine.

A separate study published on a land in 2022 found that people lost an average of 44 hours of sleep annually during the first two decades of the 21st century compared to previous periods, linking the trend directly to increasing night temperatures.

Chronic sleep deprivation disturbs the body’s ability to recover, increasing the risk of fatigue, drowsiness and accidents at work or on the road, the researchers say.

Over time, accumulated sleep loss – often referred to as “sleep debt” – can aggravate metabolic function and increase the risk of obesity, diabetes, cardiovascular disease and neurodegenerative conditions such as Alzheimer’s, according to the neuropathy.

This heat -caused fatigue emerges as a concern for public health, especially in areas facing prolonged thermal waves with minimal overnight stay.

Experts say that the results are not only natural but psychologically, as chronic heat exposure has also been linked to increased stress and reduced mental well -being.

How do we adapt to this, then, to our daily lives as citizens of a city where heat does not dissolve even in October?

Cold shower before sleeping, less chai and brown, more seasonal fruit drinks, such as Falsa and Unripened Mango Purea mixed in cold water, drinking lassi, placing wet clothes over the windows, placing a bathroom full of water in the corner of the room and the directory continues.

As the weather becomes unbearable, more and more people are falling back to local residence practices.

However, this is not something that can be treated exclusively on an individual basis.

With global warming showing no sign of deceleration, scientists encourage governments to calculate the hidden heat tax on human behavior and capacity, from productivity that is reduced to the increasing needs of health care, in the context of broader strategies.
