Research indicates that nighttime temperatures are rising faster than daytime temperatures, further compromising sleep quality.

A recent study published in The Lancet reveals that sleep loss has increased by 5% globally over the past five years, peaking in 2023, which was the hottest year on record with a 6% rise in sleep loss.

Jeremy Farrar, chief scientist at the World Health Organization, stresses that the health impacts of climate change are felt continuously, not just during extreme weather events.

The demand for air conditioning is projected to triple by 2050, further complicating the situation as temperatures continue to rise.

Poor building design exacerbates indoor overheating, particularly in temperate climates, making it crucial to improve ventilation and shading to mitigate these effects.

This rise in sleep loss is attributed to climate change, particularly due to high nighttime temperatures that disrupt sleep patterns and hinder recovery from daytime heat.

The Lancet Countdown report, involving 122 global experts, highlights the adverse health impacts of climate change, including sleep disruption caused by high temperatures and extreme weather events.

Research by Kevin Lomas shows that bedroom temperatures exceeding 27°C (80.6°F) hinder the body's cooling process, leading to significant long-term health consequences.

Lack of sleep can severely diminish attention span and quality of life, potentially worsening other health conditions, as noted by experts studying the relationship between heat and sleep.

In 2023, high temperatures resulted in a staggering loss of 512 billion potential labor hours globally, with heat-related deaths among individuals aged 65 and older increasing by 167% since the 1990s.

The study utilized historical sleep-tracking and temperature data, identifying the Middle East and sub-Saharan Africa as the regions most affected by sleep loss due to high nighttime temperatures.
