Rainy weather often brings lower barometric pressure, which can affect the pressure inside joints and tissues, leading to increased pain in past injuries.
Cold and damp weather can cause muscles and joints to stiffen. This stiffness can aggravate old injuries, making them more painful during rainy conditions.
Higher humidity levels during rain can lead to swelling in joints and tissues, which can intensify pain and discomfort from previous injuries.
Changes in weather can trigger inflammatory responses in the body, which may exacerbate pain in areas affected by past injuries or arthritis.
People tend to be less active during rainy weather, leading to muscle stiffness and reduced mobility, which can make old injuries feel more painful.
The discomfort of rain and gloomy weather can affect mood and perception of pain, making existing injuries feel worse due to heightened sensitivity.
