Tokyo - Many people in Japan set their air conditioners too cold at night in the summer and find it difficult to get a good night's sleep, a survey by major air conditioner maker Daikin Industries Ltd has found.
According to a survey conducted in July of 524 people nationwide aged 20 to 59, 44.5% of respondents were dissatisfied with using air conditioning while sleeping in the summer.
With multiple responses allowed, the most common complaint, 52.8%, was “My body feels cold and tired” when I sleep with the air conditioning on. Combined with "I wake up cold when I leave the air conditioning on" at 33%, it was evident that many were suffering from "too cold".
Of those who use air conditioning before bed, 55.5% leave the unit running until the morning, while 36.5% set a timer to turn off the units while they sleep. This last action is supposed to help people avoid getting too cold, but 33% of people who did this complained of waking up feeling hot after the timer went off.
Daikin recommends leaving the air conditioner on even while sleeping on a sultry night when the outside temperature does not drop below 25 degrees Celsius. The company also advises that users can sleep comfortably if the airflow direction is set horizontally so that the wind does not blow directly against the body. It is also recommended to place a fan opposite the air conditioner to raise the cold air near the floor to reduce the unevenness of the room temperature.
A recent survey conducted in Japan regarding summer sleep quality and air conditioning use revealed some remarkable results. The findings show that a whopping 44.5% of Japanese residents face discomfort in their sleep despite relying on air conditioning to combat the summer heat. This article dives into key findings from the survey and sheds light on the reasons for this dissatisfaction.
Struggle with sleep quality:
As temperatures rise during the steamy summer months, air conditioners have become an essential part of maintaining indoor comfort. However, the survey shows that almost half of the respondents (44.5%) struggle with insufficient sleep quality even when using air conditioning in the bedroom. This phenomenon prompts investigation into potential factors influencing this widespread problem.
Possible factors at play:
Several factors may contribute to the sub-optimal sleep quality experienced by a substantial portion of the Japanese population:
Temperature Fluctuations: While air conditioning helps maintain a cool indoor environment, sudden changes in temperature can disrupt the body's natural sleep regulation, leading to discomfort and fragmented sleep.
Humidity levels: High humidity levels, often associated with summer, can affect the body's ability to regulate temperature and humidity, which can cause discomfort during sleep.
Noise and vibration: Air conditioners can make noise and vibration that disturbs sleep, especially if they are not properly maintained or if the bedroom is not sufficiently sound-proofed.
Inadequate air circulation: Improper placement of air conditioning units or insufficient ventilation can lead to uneven cooling, leaving some areas of the room warmer than others.
Light pollution: Longer hours of daylight in summer can bring unwanted light into bedrooms, affecting the natural sleep-wake cycle.
Finding the solution:
Given these challenges, it is essential to find practical solutions that improve the quality of sleep in the summer months:
Optimum temperature setting: Experiment with different temperature settings to find the most comfortable sleeping environment.
Humidity control: Consider using dehumidifiers to maintain optimal humidity levels in the bedroom.
Noise Reduction: Ensure regular maintenance of air conditioning units and explore noise reduction strategies such as the use of soundproof curtains.
Proper ventilation: Place air conditioning units strategically to ensure even air circulation and sufficient cooling throughout the room.
Light control: Use blackout curtains or blinds to minimize light pollution during sleep.
The survey's finding that 44.5% of individuals in Japan experience poor sleep quality despite using air conditioning underscores the complexity of achieving a comfortable summer sleep. By understanding potential contributing factors and adopting practical solutions, individuals can take proactive steps to improve their sleep experiences during the challenging summer season.

In a shocking revelation, a recent survey conducted in Japan shed light on a pressing problem that affects 44.5% of the population. Despite the widespread use of air conditioning systems during the scorching summer months, a significant percentage of people struggle with sub-par sleep quality. This alarming trend calls for closer examination of the potential factors that could be contributing to this widespread dissatisfaction.
Key findings from the survey:
The survey, which included a diverse demographic in different regions of Japan, revealed a disturbing reality: nearly half of respondents (44.5%) reported dissatisfaction with sleep quality and relied on air conditioning to beat the summer heat. This puzzling revelation has raised questions about the effectiveness of air conditioning systems in promoting restful sleep during the steamy months.
Factors contributing to sleep dissatisfaction:
While air conditioning is commonly assumed to improve sleep quality by maintaining a comfortable indoor temperature, the survey results indicate a discrepancy between expectations and reality. Several potential factors may contribute to this phenomenon:
Temperature discrepancies: Research suggests that simply lowering the temperature may not be enough to ensure restful sleep. Factors such as humidity, airflow and personal comfort preferences can be equally influential.
Air quality: Air conditioning systems that are not properly maintained can circulate allergens, dust and other contaminants, which can impact sleep quality and overall well-being.
Adaptation Period: It is possible that sudden changes from outdoor heat to an air-conditioned indoor environment require an adjustment period for the body to effectively regulate its sleep patterns.
Noise and Disturbance: Noise generated by air conditioning units or disturbances related to their operation could contribute to sleep disruption and offset the intended benefits.
Use of technology: Long-term exposure to electronic devices that emit blue light before bed can disrupt the body's natural sleep-wake cycle, counteracting air conditioning efforts.
Implications and recommendations:
The survey results have implications beyond personal comfort, as sleep quality is directly related to overall health and well-being. To address this issue and improve sleep during the summer months, individuals and households could consider the following measures:
