What level of barometric pressure effects body?

A fall in barometric pressure can affect health in various ways. Mountain sickness or altitude sickness: It refers to a group of general symptoms occurring on climbing or walking to a higher altitude or elevation too quickly. At heights above 1,500-3,000 m (5,000-10,000 feet), the pressure is low enough to produce altitude sickness.

Is there any study to show how barometric pressure fall effects health?

1) dropping from 1018 mb to 1014 mb (slower speed in 1 day), which seem no effect at all.
2) dropping from 1018 mb to 900 mb (faster speed in 1 day)

How does the changing speed described on any study?

There is some evidence to suggest that changes in barometric pressure can affect blood pressure, but the exact relationship is not well understood. Blood pressure is the force of blood against the walls of the arteries, and it is influenced by a number of factors, including the volume of blood in the circulatory system, the resistance of the blood vessels, and the strength of the heartbeat.

Barometric pressure can affect blood pressure by changing the volume of blood in the circulatory system. When barometric pressure changes, it can cause a shift in the volume of fluids in the body, leading to changes in blood pressure. For example, a rapid drop in barometric pressure, such as during a weather front, can cause an increase in blood volume and a corresponding increase in blood pressure.

Again, as we've discussed in past threads, the relationship between barometric pressure and blood pressure is complex and not fully understood. Other factors, such as stress, age, and the presence of underlying medical conditions, can also play a role in blood pressure regulation. Additionally, the effects of barometric pressure changes on blood pressure can vary between individuals and are not always predictable.

Based on this study, do they mention on how much change in barometric pressure can affect blood pressure. Do you still get the reference materials?

They've only made speculations (article provided below; read the discussion section for more details)

"CONCLUSIONS
The study confirmed an inverse relationship between atmospheric
pressure and blood pressure during the spring days,
and systolic blood pressure during winter nights."

"Systolic pressure – the upper number in a blood pressure reading – measures how hard the heart pumps blood into arteries. "

Referring to your article's conclusions, during winter nights,
as AP gets lower, heart is getting harder to pump blood into arteries.
as AP gets higher, heart is getting easier to pump blood into arteries.

but this articles seem missing AP details, such as level and changing difference.

Is there any more articles related to AP details?

Thanks, to everyone very much for any suggestions (^v^)

Did you review the results section?

Yes, those data is blood pressure, not atmosphere pressure.
I would like to know on how and what atmosphere pressure levels affect blood pressure in term of SYSTOLIC and DIASTOLIC.

Furthermore, how to interpret the meaning in term of blood pressure (SYSTOLIC vs DIASTOLIC)?
such as
when SYSTOLIC is higher, how does it affect our body?
when DIASTOLIC is higher, how does it affect our body?

Blood pressure numbers of less than 120/80 mm Hg are considered within the normal range.
Blood pressure is higher than 180/120 mm Hg and you are experiencing signs of possible organ damage

The most is goes into it is in Table 2:


Blood pressure is measured using two numbers: The first number, called systolic blood pressure, measures the pressure in your arteries when your heart beats. The second number, called diastolic blood pressure, measures the pressure in your arteries when your heart rests between beats. When either the systolic or diastolic blood pressure is elevated, it can lead to health problems. For example, a high systolic blood pressure with a normal diastolic blood pressure is a sign of stiff arteries, while a high diastolic blood pressure with a normal systolic blood pressure may indicate problems with the blood vessels themselves.

What kind of blood vessels issue relate to a high diastolic blood pressure with a normal systolic blood pressure?

Do you find any related article about this issue?
Thanks, to everyone very much for any suggestions (^v^)

What you're describing is called "Isolated diastolic hypertension". Apparently this occurs due to age-related changes in the blood vessels in the heart, stiffening of the arteries, and also certain medical conditions like diabetes, kidney disease, and sleep apnea can lead to it too.
