Summer has arrived in Japan and so have hot, sleepless nights
A good night's sleep is growing increasingly elusive in Japan due to the hot and humid summer weather, with human-induced climate change partly to blame.

Japan's hot and humid summer weather is causing sleep deprivation, with climate change partly to blame. The effects of climate-attributed sleep loss are not evenly distributed, with vulnerable demographics such as infants, older adults, and pregnant women being hit harder.
Imagine you're trying to sleep, but it's too hot and humid outside. That's what's happening in Japan right now. The hot weather is making it hard for people to sleep, and it's not just because of the heat. Climate change is also playing a role. It's like when you're trying to sleep, but your brain is too busy thinking about all the things you need to do tomorrow. That's what's happening to people in Japan, and it's affecting their health.
Analysis
A Growing Sleep Deficit in Japan
The hot and humid summer weather in Japan has become a significant concern for residents, with a good night's sleep increasingly elusive without the heavy use of air conditioning. The situation is exacerbated by human-induced climate change, which is at least partly to blame for the growing sleep deficit. According to an analysis by Climate Central, the amount of temperature-related sleep loss linked to climate change has at least doubled since the early 1970s, severely straining people's health.
The Impact of Climate Change on Sleep
The analysis revealed that over five years through 2025, the average person globally lost nearly 56 hours of sleep per year due to high temperatures. More than 10% of that sleep loss was attributed to climate change, primarily caused by burning fossil fuels like coal, oil, and gas, and cutting down forests. The effects of climate-attributed sleep loss are not evenly distributed, with vulnerable demographics such as infants, older adults, and pregnant women being hit harder.
The Consequences of Sleep Deprivation
Sleeplessness can cause a variety of health issues, including poor concentration, lower productivity, weaker immune systems, depression, and anger. A chronic sleep shortage raises the risk of diabetes, high blood pressure, and severe brain and heart conditions such as strokes and heart attacks. In addition, sleep deprivation is a major cause of traffic accidents. The U.S. National Highway Traffic Safety Administration estimates 91,000 crashes reported to police in 2017 involved drowsy drivers, leading to nearly 800 deaths and an estimated 50,000 people injured.
Key points
- Japan's hot and humid summer weather is causing sleep deprivation.
- Climate change is partly to blame for the growing sleep deficit.
- The effects of climate-attributed sleep loss are not evenly distributed.
- Sleeplessness can cause various health issues, including poor concentration, lower productivity, and increased risk of diabetes, high blood pressure, and severe brain and heart conditions.
- A chronic sleep shortage raises the risk of traffic accidents.
If the development of climate-resilient sleep solutions continues, people in Japan may be able to sleep better during the hot summer months. This could be achieved through the development of more efficient air conditioning systems, the use of natural cooling methods, or the creation of sleep-friendly urban environments.
If climate change continues to worsen, the sleep deficit in Japan may become even more severe, leading to increased health problems and decreased productivity. This could have significant economic and social implications, particularly for vulnerable demographics such as infants, older adults, and pregnant women.
