Does Rainy Weather Trigger Your Migraines, Joint Pain, or Other Symptoms?

A rainy day brings more than wet weather, for many people, it brings a wave of headaches, stiff joints, or fatigue. The culprit is often barometric pressure, which drops before and during rainfall and can set off a cascade of physical reactions. Tracking rainy days alongside your symptoms in Trace Health helps you discover whether weather is a reliable trigger for how you feel.

Health effects

Barometric pressure, the weight of the atmosphere pressing down on your body, drops noticeably before and during rain. For migraine sufferers, this pressure shift is one of the most well-documented environmental triggers. Lower pressure creates a pressure difference between the outside environment and the spaces inside your sinuses and skull, which can activate pain-sensitive nerves and kick off a migraine attack. Joint pain is another common rainy-day complaint, particularly for people with arthritis, fibromyalgia, or old injuries. When barometric pressure falls, tissues around joints may expand slightly, increasing pressure and discomfort in already-sensitive areas. Many people with rheumatoid arthritis or osteoarthritis report that they can 'feel rain coming' hours before it arrives. Rainy days also tend to reduce sunlight exposure, which can suppress serotonin levels and contribute to low mood, fatigue, or symptoms associated with seasonal affective patterns. Staying indoors more and moving less on wet days can compound feelings of stiffness or low energy. For some individuals, however, rainy days offer relief. Cooler, humid air can soothe dry airways and ease symptoms for those sensitive to heat or dry conditions. People prone to heat-triggered headaches or skin flare-ups may actually feel better when temperatures drop with rainfall. The key is that rainy weather does not affect everyone the same way. Your personal pattern, trigger, reliever, or neutral, is something only consistent symptom tracking can reveal.

Frequently Asked Questions

Why do I get a headache or migraine when it rains?

The most likely cause is the drop in barometric pressure that occurs before and during rainfall. This pressure change can affect the fluid and pressure balance inside your head, triggering pain-sensitive nerve pathways associated with migraines. Sinus pressure changes, reduced sleep quality due to storms, and lower light levels can also contribute. Logging rainy days in Trace Health alongside your headache severity can help you confirm whether pressure changes are a consistent migraine trigger for you.

Does rainy weather make joint pain worse?

Many people with arthritis, fibromyalgia, or previous joint injuries report increased pain and stiffness on rainy days, and research supports a link to falling barometric pressure. When pressure drops, soft tissues around joints may expand slightly, amplifying discomfort in sensitive areas. Cold and damp conditions can also reduce circulation and increase muscle tension around affected joints. Tracking your joint pain scores against rainy weather in Trace Health over several weeks can reveal how strong this connection is for your body.

Can rainy days affect my mood or energy levels?

Yes, rainy days reduce natural light exposure, which can suppress serotonin production and raise melatonin levels, leaving you feeling sluggish, low, or unmotivated. This is especially pronounced for people who are sensitive to seasonal light changes. Reduced physical activity on wet days can also contribute to fatigue and a dip in mood. By tagging rainy days in Trace Health and logging your energy and mood scores, you can see whether overcast weather consistently correlates with your emotional and physical wellbeing.

  • “Ok so I try so hard to track symptoms but apple health doesn’t have a widget for that and it’s kind of a pain to track down every little thing… Now this app!!!! Everything is right there, there’s widgets, it’s fast and simple and syncs! I freaking love this app! I’m still playing with it so I haven’t seen if it has a “how are you feeling right now” feature but it is everything I have ever wanted the symptoms on health to be!” (grofica82, United States)
