Other Factors

• Sunshine seems to play a role in how you feel. A study in the journal "Emotion" by Dr. Jaap J. A. Denissen and colleagues notes that people reported feeling better on sunny days. Often, on clear and sunny days, high pressure dominates the weather, establishing an indirect link between barometric pressure and mood.
  
  

Barometric Pressure, Pain and Mood

Studies by Tufts University researchers claim that barometric pressure, along with temperature, can affect osteoarthritis symptoms. Researchers believe that the level of pain experienced impacts mood.
  
  

Barometric Pressure, Cognition and Mood

• Russian scientists and others report that low barometric pressure curtails mental activity, including attention span and short-term memory. Impaired cognitive function on a somewhat regular basis can impact your mood and how you feel about yourself.
