how does weather affect pain Archives - Minnesota Physical Medicine Blog

The weather can affect your mood, but can it also affect how pain is expressed and felt in your body? According to new research out of the United Kingdom, certain whether patterns may make your chronic pain condition worse. Below, we take a closer look at what the study uncovered, and we explain why certain weather patterns may lead to a chronic pain flareup.

Chronic Pain and The Weather

To better understand how weather systems affected individuals with pain, researchers from the University of Manchester conducted a 15-month study involving more than 13,000 people living with chronic pain. Patients were asked to record their pain intensity each day with the help of a smartphone app. GPS location data was also used to record the weather data for the individual’s location. Researchers ranked all tracked days, and the most painful days saw 23 percent of participants report an increase in pain, whereas only 10 percent said the same on the days ranked as the least painful days.

Researchers took the 45 highest ranking days for pain and averaged the weather conditions to determine the weather patterns that were present on the days when the most amount of people were in pain. The same was done for the 45 lowest ranking days. Here’s what they found:

On the most painful days, the jet stream was aimed right at the UK, with below-normal pressure over the UK.
On the most painful days, the humidity and precipitation rate were both above-normal.
On the least painful days, there was above-normal pressure over the UK.
On the least painful days, the humidity and precipitation rate were both below-normal, and winds were weaker.

Co-lead researchers Professor David Schultz, Department of Earth and Environmental Sciences at the University of Manchester, and Professor Will Dixon, had this to say about the study:

“Over 2400 years ago, Hippocrates wrote that different wind directions could bring better or worse health to individuals,” said Professor Dixon. “The belief by people living with long-term pain conditions, such as arthritis, that their pain is affected by the weather remains prevalent today, with about 75% of people with chronic pain believing this to be true. Yet, there is disagreement over what weather condition makes their pain worse.”

“Part of the reason for this lack of consensus is that previous researchers have treated the different measures of the weather such as pressure, temperature, humidity separately, which assumes that one could vary the temperature while holding all of the other weather measures fixed,” said Professor Schultz. “Of course, the real atmosphere does not behave like this, as all the variables are changing simultaneously. A simple analysis clearly won’t do to get at understanding how weather affects pain.”

The leading theory is that when low pressure systems arrives, the pressure against your joints drops as well, which can make swelling and inflammation worse. Our bodies then react to this inflammation, which can lead to an increase in pain sensations. It’s far from a concrete science, but this study seems to provide more proof that there is at least a correlation between certain weather conditions and an increase or decrease in chronic pain.

The summer is here and it’s time to be outdoors. Summer heat and the change of seasons can have a variable effect on pain, as medical conditions react differently to weather changes. Most pain conditions often do better during the summer, since the warmth allows muscles and joints to move more comfortably. Summer also allows for more time to use the outdoors as a place to exercise.

The warmth of summer is often a blessing for those with painful conditions. Muscles in the warmth often do not tighten up, and thus hurt less. Joints are less stiff since they are not cold. Now is the time to get some exercise. Start exercising slowly, warm up and stretch your muscles as you get going. Remember, if you have not been exercising, do not over do it initially. Walking is good exercise, and gradually increase your pace, distance and time as you build up strength. Go for 30 minutes a day and meet the American Heart Association goals for cardiac conditioning. If walking is too slow, bicycling is another low impact activity that can easily get the heart moving. Exercise stimulates the body’s endorphins, improves the brain function and decreases pain. Get a fitness tracker and monitor whether you are meeting your goals.

Pace, Hydration and Sun Protection

Once the weather turns nice, many of us forget common sense. We need to pace our selves especially with activities that we have not done or which are repetitive. Spending a weekend doing extensive landscaping is likely to cause injury. Heavy lifting and highly repetitive jobs or sports may damage the back or muscles, tendons and ligaments. Be reasonable and break up the tasks that need to be done to prevent problems.

The summer is a great time to be outdoors. However, do not forget to hydrate and protect against the sun. Dehydration is easy if it is hot and humid outside. Drink plenty of water, and if you are sweating excessively, drink liquids that replace nutrients. Avoid drinking alcohol when its hot outside since this tends to lead to dehydration. Remember the sunscreen when outdoors, as new studies show men ignore using sunscreen and have a higher incidence of skin cancer.

Summer is a good time to have some fun. Relax, exercise and enjoy the outdoors. There are many benefits of being outside and taking advantage of the good weather. Use a little common sense and your pain may greatly improve.
