For Yemeni beekeeper Mohammed Saif, honey production used to be a lucrative business but years of war and climate change have taken the buzz out of the family hives.

The business, handed down from father to son, "is slowly disappearing", Saif told AFP. "The bees are being hit by strange phenomenons. Is it due to climate change or the effects of war? We really don't know."

Yemen, one of the world's most impoverished countries, has been gripped by a deadly conflict since 2014.

In the southwestern region of Taiz, Saif recently took stock of his hives in a rugged valley surrounded by mountains.

Before the war, Saif said, the family managed 300 hives, now only 80 are left.

Experts consider Yemeni honey some of the best in the world, including the prized Royal Sidr known for its therapeutic properties.

The United Nations says honey plays a "vital role" in Yemen's economy, with 100,000 households dependent on it for their livelihoods.

But "enormous losses have been inflicted on the industry since the outbreak of the conflict", the International Committee of the Red Cross said in a report in June.

"Armed conflict and climate change are threatening the continuity of a 3,000-year-old practice," the ICRC said.

"Successive waves of displacement to flee violence, the impact of weapon contamination on production areas, and the growing impact of climate change are pushing thousands of beekeepers into precarity, significantly reducing production."

Saif knows it all too well.

"Last year in our village a missile struck a beekeeper's hives. He lost everything," he said.

"The war has had a very bad impact on us. The fighters have targeted many zones where bees are found," he added.

The ICRC's Bashir Omar said the conflict had limited the ability of beekeepers to freely roam the land whenever flowers were in bloom to collect the honey.

Landmines and active front lines are among the challenges they face.

"To make matters worse, Yemen, like many conflict-affected countries, is disproportionately affected by climate change," the ICRC report noted.

"Temperature rises in recent years, combined with severe alterations caused to the environment, are disturbing the bees' ecosystem which is impacting the pollination process," it said.

"With water tables falling and increased desertification, areas previously engaged in agricultural activities and beekeeping no longer sustain these livelihoods."

The ICRC is providing financial support and training this year to beekeepers, after a similar initiative in 2021 that helped nearly 4,000 of them.

Nabil al-Hakim, who sells Yemen's celebrated yellow nectar in Taiz shops, also recalled the golden days before the conflict ravaged his country.

"Before the war we could make a good living by selling honey... but honey has become rare and customers can no longer afford it," he said.

"Before, I used to sell up to 25 five-liter jars a month. Now I can't even sell one."

Cool showers and less coffee or alcohol: sleep quality is being harmed by hotter temperatures caused by climate change, and scientists say we need to learn how to adapt.

The human brain is very sensitive to heat, with higher temperatures raising the body's central thermostat and activating stress systems.

Scientists are increasingly exploring mechanisms that can help the body adapt to rising temperatures affecting our sleep and leading to health complications.

"Rising temperatures induced by climate change and urbanization pose a planetary threat to human sleep, and therefore health, performance, and wellbeing," according to a 2024 review of scientific literature published in the journal Sleep Medicine.

Humans lost an average of 44 hours of sleep a year during the first two decades of the 21st century compared to earlier periods, according to a 2022 study published in the journal One Earth, which linked the data to rising temperatures.

The intensification of global warming could lead to an annual loss of 50 to 58 hours of sleep per person by 2099, according to research led by Kelton Minor, from the University of Copenhagen, based on data gathered from more than 47,000 individuals in 68 countries.

"Interventional studies and field experiments are now urgently needed to foster adaptation and safeguard the essential restorative role of sleep in a hotter world," Minor and other authors of the paper said.

Neurons regulating temperature and sleep in the brain are highly interconnected, and lowering the body's internal thermostat is key to improving sleep quality.

Adapting to heat comes at a cost to the body, according to Fabien Sauvet, a researcher at Paris Cite University.

"We sweat more and faster, for example, but it requires additional hydration. And it has limits, so during heatwaves, the most important thing is to adapt our behavior," such as activities, schedules and clothing, Sauvet said.

But humans could "tolerate higher temperatures than commonly thought", he added, pointing to several studies showing that good sleep quality can be achieved with a room temperature of up to 28 degrees Celsius (82.4 degrees Fahrenheit).

Challenging "the false belief that the bedroom must be at 18-20C", he said that sleeping in light clothing such as a t-shirt and shorts, and with a simple sheet as well as good ventilation, could help dealing with a few more degrees.

"If we always sleep with air conditioning, we will never acclimatize," he said.

Armelle Rancillac, a neuroscientist at the Center for Interdisciplinary Research in Biology, said anything beyond 28C "becomes much more complicated".

An excessive lack of sleep is known to disrupt the body's recovery.

In the short term, this can lead to drowsiness, fatigue and a higher risk of accidents at the workplace or on the road.

In the long run, it can create a harmful sleep "debt", impacting our metabolism and increasing the risk of weight gain, diabetes, cardiovascular diseases and even neurodegenerative diseases like Alzheimer's, Rancillac said.

A sleep deficit can also reduce stress resistance and have a negative impact on mental health.

To sleep better in a hotter environment, Rancillac stressed that there is a need to "eliminate or at least pay attention to sleep enemies".

Before bedtime, it is recommended to take a cool shower -- but not an icy one -- reduce stimulants like coffee, and limit alcohol, which facilitates falling asleep but slightly raises the internal body temperature.

Avoid hot tubs after a workout, opting instead for outdoor temperatures or a cold bath, said Sauvet.

Napping during the hottest hours of the day have also been proven to mitigate the impacts of a sleep deficit.

Short naps -- "30 to 40 minutes, and before 2:00 pm" -- are ideal, so as not to interfere with a good night's sleep, according to the researcher.
