Hot weather typically doesn't cause true MS relapses, but it can temporarily worsen your symptoms. This happens because heat affects how demyelinated nerves carry signals between the brain and body. About 60-80% of people with MS experience this heat sensitivity, known as Uhthoff's phenomenon.

Hot weather typically doesn't cause true MS relapses, but it can temporarily worsen your symptoms. This happens because heat affects how demyelinated nerves carry signals between the brain and body. About 60-80% of people with MS experience this heat sensitivity, known as Uhthoff's phenomenon.

Common heat-related MS symptoms include:
• Increased fatigue
• Muscle weakness and cramps
• Balance and coordination problems
• Blurred vision
• Difficulty concentrating
• Muscle spasticity The good news is that these symptoms are temporary. Once your body temperature returns to normal, symptoms should return to your usual baseline levels. Many MyMSTeam members describe similar experiences, with some saying it feels like "walking through Jell-O" on hot days.

To manage symptoms in hot weather:
• Stay in air-conditioned environments when possible
• Stay hydrated
• Avoid direct sun exposure during peak hours
• Use cooling products like neck wraps or vests
• Plan activities during cooler parts of the day
