Your brain's supply of blood is hyper-sensitive to oxygen changes. If the oxygen pressure in the air dips, the brain prepares to have more oxygen delivered to it. It instructs the body to dilate blood vessels headed to the brain, which increases blood flow… Thus, you get a barometric pressure headache.
When the Barometric Pressure is high, the pressure pushes more against our body and limits how much tissue can expand. On the other hand, when the atmosphere's air pressure is low, it allows our body's tissues to expand more—putting more pressure on nerves and other parts of our body.
Barometric pressure not only affects the weather, but it can also affect the human body. When the barometric pressure changes, the partial pressure of oxygen changes, which can lead to headaches, joint pain and multiple other symptoms.
Barometric pressure headache symptoms
In addition to typical migraine symptoms like nausea, vomiting and light and sound sensitivity, those who have a migraine triggered by barometric pressure may experience the following: Facial discomfort or pain around their sinuses. Post-nasal drip.
These results indicate that changes in barometric pressure induce sympathetic activation both in rodents and humans. The influence of sympathetic nerve activities on nociceptive afferents after nerve injury is well documented [37–39].
Weather-sensitive pain is caused by the Sympathetic Nervous System. This portion of the nervous system monitors for injury of soft tissues in the body.
Another idea: Changes in barometric pressure may make your tendons, muscles, and any scar tissue expand and contract, and that can create pain in joints affected by arthritis. Low temperatures can also make the fluid inside joints thicker, so they feel stiffer.
Chronic Back Pain: As with joint pain and arthritis, for those who experience chronic back pain, the extreme change in barometric pressure can cause inflamed joints to swell more, perpetuating preexisting pain. Cold temperatures also do not help as it stiffens the joints, tendons, and muscles which support the spine.
The low light conditions associated with rainy weather can lead to a spike in melatonin, making you feel drowsy. Yet another reason for feeling tired or “down” in rainy weather is the effect of barometric pressure.
Some people really can feel atmospheric pressure changes within their bodies. Those with migraine, diabetes, high or low blood pressure, or osteoarthritis are the most susceptible to extra aches and pains before a storm.
“Additionally, we found associations between barometric pressure and brain volume. Basically, when the weather is bad, such as during storms or winter, the cerebellum shrinks and the rest of the brain grows in volume,” Book said. “In summer and when there is high pressure, or nice days, the opposite happens.
Vanos said people are most comfortable with barometric pressure of 30 inches of mercury (inHg). When it rises to 30.3 inHg or higher, or drops to 29.7 or lower, the risk of heart attack increases.
People are most comfortable with barometric pressure of 30 inches of mercury (inHg). When it rises to 30.3 inHg or higher, or drops to 29.7 or lower, the risk of heart attack increases. A barometric reading over 30.20 inHg is generally considered high, and high pressure is associated with clear skies and calm weather.
Warm baths and hot compresses
A bit of rest and relaxation in warm water can be very soothing to your achy joints. The heat relaxes the muscles and increases blood flow. A hot compress or hot water bottle will also do the trick.
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.
However, many people diagnosed with fibromyalgia say that weather has an effect on how they feel. Sudden drops in barometric pressure, as well as extreme temperatures may make pain much worse. Though it may not help all fibromyalgia sufferers, finding a better climate may help ease some symptoms of this condition.
Sensitivity to changes in the weather
There are published studies that have related the pain in fibromyalgia to weather changes. Some studies report that barometric pressure affected fibromyalgic pain positively while yet others find no association.

There's a grain of truth to it. For some people, a change in weather or onset of fall and weather seem to trigger colds, seasonal allergies or other respiratory illnesses. “Certain bacteria and viruses thrive in different types of weather,” Dr. Bast said.
Studies have shown that changes in atmospheric pressure can impact your stress level and your health.
Find the adjustment screw on the back, and carefully turn this with a small screwdriver so that your barometer needle points to this pressure on the dial. Tap it gently in case it is sticky, and re-adjust if necessary.
High blood pressure forces the heart to work harder to pump blood to the rest of the body. This causes the lower left heart chamber (left ventricle) to thicken. A thickened left ventricle increases the risk of heart attack, heart failure and sudden cardiac death.
