Effect of atmospheric pressure on volcanic eruptions?Report of sudden illness-Weathernews

2022/01/20 16:40 Weathernews

On the night of Saturday, the 15th, when there was a volcanic eruption in Tonga, there was a temporary change in atmospheric pressure nationwide. Weathernews interviewed users to see if their physical condition changed on the 15th and 16th.

As a result, regarding 20% of the respondents answered that they felt some influence from sudden changes in physical condition over the two days of the 15th and 16th due to changes in atmospheric pressure and weather.

Atmospheric pressure changes significantly at night on Saturday, 15th

Looking at the change in atmospheric pressure on the night of the 15th (Saturday) by Soratena, an observation aircraft that Weathernews has independently installed at 3000 locations nationwide, once the atmospheric pressure rises (displayed in red), the atmospheric pressure immediately rises. A descent (displayed in blue) has occurred, and it appears that it is propagating concentrically. It is a change of regarding 2hPa.

It is presumed that this captures the pressurization (pressure rise) → decompression (pressure drop) peculiar to the shock wave.

Sudden changes in physical condition before and following a large change in atmospheric pressure

It was reported that this large change in atmospheric pressure and subsequent changes in sea level continued, so there was no major bias in the region and there was a change in physical condition.

Atmospheric pressure changes significantly at night on Saturday, 15th

Atmospheric pressure changes began on the southeastern side of the Japanese archipelago, such as the Kanto and Izu Islands.

Looking at the change in atmospheric pressure caused by Soratena, an observation aircraft that Weathernews has independently installed at 3,000 locations nationwide, the atmospheric pressure rises (displayed in red) and then immediately drops (displayed in blue). It has happened and is appearing to propagate concentrically. It is a change of regarding 2hPa.

It is presumed that this captures the pressurization (pressure rise) → decompression (pressure drop) peculiar to the shock wave.

It is unlikely that this shock wave will have any effect, but it is a phenomenon that indicates the scale of this volcanic eruption.

Females have a greater influence and are different in age

Looking at the male-female ratio in detail, the ratio was significantly different, with 35% of females and 14% of males, and the result was that there were more females.

By age group, females are affected by age, with regarding 30% in their 30s and nearly 40% in their 40s and 50s.

On the other hand, it seems that younger men are more affected, but there is no big difference compared to females.

Symptoms include “headache” and “tinnitus”

Many respondents answered “headache” for the symptoms and areas where they felt pain this time.

There were also many comments saying “tinnitus”. For a moment, it seems that there was a sudden change like entering the tunnel by Shinkansen due to a sudden change in atmospheric pressure.

It is said that weather pain is closely related to the inner ear, and it is thought that it affected the disturbance of the barometric pressure sensor and autonomic nerves.

Also, it seems that some people felt “dullness” as well as neck, shoulders, hips and old injuries.

Prepare for sudden weather pain

Disorders and pain caused by changes in atmospheric pressure, humidity, and temperature are called “weather pain.” I don’t know the direct causal relationship because the affected time zone varies and the feeling differs depending on the physical condition of the day, but some people suffer from sudden changes in physical condition due to large changes in atmospheric pressure. I think.

By knowing patterns such as changes in your physical condition on a daily basis and checking the forecast, you can take measures early and alleviate your symptoms.
