Whenever the air pressure stays below 1008 hPa for several hours or the air pressure falls from its intraday high for more than 4 hPa or the fall is too rapid, my depression got worse (feeling very low in energy, want to lie down without stamina.I will feel very sleepy and have more bad dreams. I will also be more irritable). I am sharing my experience here, hoping to find other depression patients to reconfirm my findings. If the low pressure worsens my depression, I guess it is because it lowers the saturation of oxygen in air, so I am currently taking some high altitude medicine to boost the oxygen saturation in my blood. It might be working so far but I need more time to reconfirm its efficacy. Pls share you experience if any.
