If you thought that the rising temperatures are only reflected in the weather, you are completely wrong - they have a decisive effect on our body.

A large study of its kind has found that rising temperatures driven by the climate crisis are disrupting the sleep of people around the world, which is very worrying.

Good sleep is critical to health and quality of life in general.

But global warming is raising temperatures at night, even faster than during the day, making it difficult for many to sleep.

The analysis revealed that the average person already loses 44 hours of sleep a year, leading to 11 nights with less than seven hours of sleep - which is a standard standard of adequate sleep.

Lost hours of sleep will increase even more as the earth continues to warm up, and this affects some groups much more than others.

Warm-up sleep loss is about a quarter higher for women than men, twice as high for people over 65 and three times as high for those in less affluent countries.

The researchers used data from sleep tracking bracelets used by 47,000 people in 68 countries.

The heat causes poor sleep and this harms everyone's health.

Previous studies have shown that rising temperatures are detrimental to health, causing increased heart attacks, suicides and mental health crises, accidents and injuries, as well as reduced work capacity.

Poor sleep has also been shown to have similar effects, and the researchers said their research suggests that poor sleep may be a key mechanism by which heat causes these health effects.

Worryingly, the researchers said, their data showed no signs that people could adapt to warmer nights.

"For most of us, sleep is a very essential part of our daily routine; we spend almost a third of our lives asleep," the Guardian Celton Minor, from the University of Copenhagen, Denmark, who led the study, told the website.

"But a growing number of people in many countries around the world are not getting enough sleep."

Minor said reduced sleep on warmer nights affects huge populations.

For example, he said, a night of over 25 degrees in a city of a million people would result in 46,000 people suffering from shorter sleep.

"And if you look at the heat wave that is currently happening in India and Pakistan, we are talking about billions of people who have been exposed to conditions that are likely to cause significant sleep loss," Minor said.

The study, published in the journal One Earth, analyzed sleep and weather data collected from 2015 to 2017 and found that higher temperatures reduced sleep by delaying bedtime and falling asleep.

This is probably because people's bodies need to cool down every night when they fall asleep and it is harder when the temperatures are high.

Women's urination may be more affected because their body usually cools more slowly than men's when going to bed.

Women also have higher levels of subcutaneous fat on average, which makes cooling down slower.

Older people are known to sleep less at night and have poorer body temperature regulation, which may explain their sensitivity to rising temperatures.

People in poorer countries may lose more sleep because they have less access to cooling features such as window shutters, fans and air conditioning.
