Why Your Knee Pain Feels Worse in Hot Weather

Why Your Knee Pain Feels Worse in Hot Weather

Are your knees more accurate than the weather channel?

Sudden changes in temperature and air pressure are often felt in the joints. While colder weather can lead to stiffness and discomfort, hot weather can worsen pain. Understanding why these changes occur can help you develop a plan to alleviate the symptoms and enjoy the beautiful weather without worrying about your knees.

To help you out, we asked our expert, Dr. Thomas Kane III, to discuss how hot weather affects the knees and what can be done about it.

Dehydration may worsen pain

High temperatures can lead to excess sweating and dehydration, which reduces the fluid that cushions your joints. When the natural lubrication in the knee decreases, friction within the joint increases, leading to inflammation and discomfort. Always carry a water bottle, and consider adding electrolytes to maintain proper hydration. Salt is an electrolyte, and adding a pinch to your water can help.

Humidity may cause swelling

Humidity can make things worse by causing your tissues to expand and retain fluid. This may increase pressure in and around the joint, especially in already inflamed knees. Combined with dehydration, humid weather can throw your joint balance off and make everyday movement painful.

Wearing loose, breathable fabrics that don’t cling to the skin, such as cotton and linen, can help you stay cool and dry. 

Heat cramps may occur

Heat cramps are muscle spasms caused by a loss of essential minerals like sodium and potassium. These electrolytes regulate muscle function, and when lost through sweat, your knee and leg muscles may cramp up or become fatigued, adding to joint strain. 

These cramps may appear suddenly, especially during or after physical activity. Stretching, staying hydrated, and replenishing electrolytes quickly can help soothe muscle tension before it escalates.

If you have knee issues and want to play a sport during the summer, ensure you have access to water with electrolytes and, preferably, opt for indoor facilities that are cooler. 

Get help for your knees

While home remedies may provide temporary relief, persistent or worsening knee pain should never be ignored. The right treatment can slow down the progression of the disease and significantly increase the quality of life.
