We are now heading into the “dog days of summer”, commonly described as the most oppressive period of summer heat.  Summer and hot humid weather can be a challenge to all of us, but especially for those living with lymphedema. However, being aware of the complications presented by these warmer months can help prevent further issues and complications when living with lymphedema.


When the temperatures begin to soar those living with lymphedema can have an especially difficult time with the heat. Blood vessels expand with heat, causing the amount of fluid that travels out of the blood vessel and into the tissue to increase. With a compromised lymphatic system the fluid does not always return like it should to the lymph system. This can result in further swelling and edema.
Staying out of the heat is not always an option and we still want to enjoy our summer. Here are some tips and tricks to help best enjoy the dog days of summer while also taking care of your lymphatic system.
