From today, the 6th (Monday) to tomorrow, the 7th (Tuesday), a low pressure system accompanied by a front will develop and head north of Hokkaido. As a result, atmospheric pressure fluctuations are expected to increase nationwide.
According to weather forecasts released by Weather News, there are many predictions in the “caution” category from Hokkaido to Kyushu. Please be careful if you are prone to weather-related symptoms such as headaches or joint pain due to changes in atmospheric pressure.
Air pressure changes due to the passage of a low pressure system. After falling, it suddenly turns to rise.
As the low-pressure system continues to develop and approach the area, changes in atmospheric pressure will increase today along with stronger rain and wind.
Before a low pressure system or front passes, the pressure decreases, and after the low pressure system or front passes, the pressure starts to increase. As a result, atmospheric pressure fluctuations are expected to increase into tomorrow.
Also, this week it is expected that whole lines and low pressure systems will pass periodically, so there will be large fluctuations in atmospheric pressure throughout the week. Although it varies from person to person, symptoms of weather pain such as headaches and joint pain may occur.
Additionally, the temperature changes greatly throughout the week, which is a concern for the strain on the body. Please be careful not to feel unwell.

“Caution” and “some caution” will continue from now on.
The key to weather pain is atmospheric pressure.
It is said that not only changes in the weather such as sunny or rainy weather, but also temperature, humidity, and atmospheric pressure are greatly involved.
In particular, we can feel changes in temperature and humidity on a daily basis, such as “hot/cold” or “humid/dry,” but it is difficult to feel changes in atmospheric pressure.
WeatherNews’ Weather Pain Forecast builds its prediction logic for Weather Pain by focusing on changes in atmospheric pressure, which is difficult to feel with the skin, among the weather factors that cause it.
(2) The rise and fall of atmospheric pressure that repeats at approximately fixed times twice a day (atmospheric tides)
On the other hand, there are patterns that are not clearly expressed in weather maps, but which give us a sense of weather pain. It is thought that this may be related to “atmospheric tides.”
To explain atmospheric tides in an easy-to-understand manner, they refer to periodic changes in atmospheric pressure that occur due to sunlight warming the atmosphere during the day and cooling it after sunset. This is a change in atmospheric pressure that occurs in a half-day cycle that repeats ups and downs.
This cycle may match the cycle of human biological rhythms, and although it is a 1/1000 level change compared to the atmospheric pressure fluctuation at the weather map level in (1), it is a trigger for weather pain. .
This change is generally high around 9:00 and 21:00, and low around 3:00 and 15:00. Even when there are no low pressure systems or typhoons, the range of atmospheric pressure fluctuations seems to be around several hPa.
Previous research has also shown that the risk of developing weather pain increases when the range of up-and-down fluctuations becomes larger than the average state.
(3) Periodic small pressure fluctuations
Finally, there is something called micropressure fluctuation, which is a smaller change than the atmospheric tide mentioned earlier, and compared to the atmospheric pressure fluctuation at the weather map level in (1), it corresponds to a very small change of 1/10000 level.
Examples of micropressure fluctuations occur when a cyclone approaches, when cumulonimbus clouds form, and due to the influence of airflow over mountains.
The amount of pressure change due to micropressure fluctuations is less than 1 hPa, and the duration is short, ranging from a few minutes to several tens of minutes, but when it occurs, it often occurs multiple times a day.
Although the vibrations are smaller and more detailed than the two patterns above, it is thought that even such minute changes can have an impact on people who have sensors that are sensitive to weather.
