A barometric reading below 29.80 inHg is generally considered low, and low pressure is associated with warm air and rainstorms….Low Pressure

Fronts are not included on weather maps because they are unstable.

On weather maps, these readings are represented as a blue “H” for high pressure or a red “L” for low pressure.

1. Rising or steady pressure indicates clearing and cooler weather.
2. Slowly falling pressure indicates rain.
3. Rapidly falling pressure indicates a storm is coming.

That means air exerts 14.7 pounds per square inch (psi) of pressure at Earth’s surface. High in the atmosphere, air pressure decreases. With fewer air molecules above, there is less pressure from the weight of the air above. As the air rises, the water vapor within it condenses, forming clouds and often precipitation.

Researchers saw a connection between an increase in medication sales and changes to barometric pressure. From this, the researchers concluded that a decrease in barometric pressure causes an increase in the incidence of headaches. The barometric pressure doesn’t have to change drastically to cause headaches, either.

Although barometric pressure can’t be predicted as accurately as the other elements just mentioned, it has a major influence on fish behavior.

Barometric pressure is the weight of the atmosphere that surrounds us. Barometric pressure often drops before bad weather. Lower air pressure pushes less against the body, allowing tissues to expand. Expanded tissues can put pressure on joints and cause pain.

In “bad” or stormy weather, barometric pressure drops so that there is less pressure to push against the body. This allows tissues around the joints to expand, putting pressure on the joints and increasing pain.

Changes in barometric pressure can cause expansion and contraction of tendons, muscles, bones and scar tissues, resulting in pain in the tissues that are affected by arthritis. Low temperatures may also increase the thickness of joint fluids, making them stiffer and perhaps more sensitive to pain during movement.

Low barometric pressure fatigue Low barometric pressure can also cause fatigue. This happens for several reasons. Firstly, low barometric pressure is synonymous with low light levels. These low levels of natural light can cause our bodies to produce more melatonin.

Air pressure, also called barometric pressure, indicates how the weight of the atmosphere above is shifting. A falling air pressure generally means there is an approaching storm that will arrive within the next 12 to 24 hours. The farther the barometric pressure drops, the stronger the storm.

In addition to cold weather, blood pressure may also be affected by a sudden change in weather patterns, such as a weather front or a storm. Your body — and blood vessels — may react to abrupt changes in humidity, atmospheric pressure, cloud cover or wind in much the same way it reacts to cold.

Atmospheric pressure, also known as barometric pressure (after the barometer), is the pressure within the atmosphere of Earth. The standard atmosphere (symbol: atm) is a unit of pressure defined as 101,325 Pa (1,013.25 hPa; 1,013.25 mbar), which is equivalent to 760 mm Hg, 29.9212 inches Hg, or 14.696 psi.

Barometric pressure changes cause expansion and contraction of the ligaments, tendon, and cartilage within the joint and this causes the increase in pain.

Supplements and Medications To Help Joint Pain

1. Vitamin D. The number one supplement I recommend for joint health and overall musculoskeletal health is vitamin D3.
2. Estrogen. Estrogen is important for musculoskeletal health, including joint health.
3. Glucosamine and Chondroitin Sulfate.
4. MSM.
5. Turmeric.
6. Omega 3.
7. Ginger.
8. SAMe.

Some people may be more sensitive to weather changes experiencing more stiffness, pain, and swelling with a barometric pressure decline. Scientists suggest that a fall in air pressure allows the tissues (including muscles and tendons) to swell or expand.
