Hot Weather and Parkinson’s Disease: Six Tips for Beating the Heat

Heat and humidity can make Parkinson's symptoms worse. People with low blood pressure may feel more dizzy or lightheaded. Cramping, also known as dystonia, might come on more often. Some people have trouble regulating body temperature and don't sweat enough, which can increase risk for heat-related conditions like heat stroke or exhaustion.

Here are ways to stay cool and limit your risk of heat-related Parkinson's symptoms.

Drink Lots of Water

Even without the heat, most people should drink between six and eight 8-ounce glasses of water per day. In the heat, especially if you sweat a lot, you will need more. Fill a jug with water and pull from there throughout the day. Keep a water bottle with you all the time, even when you go out. Flavor your water with fruits, veggies or electrolyte packets if that helps you drink more.

Eat more fruits and veggies, which by nature have a higher water content and so can help you keep hydrated. And limit alcohol and caffeine, which can actually be dehydrating.

Make Virtual Doctor's Appointments

If possible, switch your doctor and other appointments to online instead of in-person. That way you can avoid having to go out in the heat.

Stay Indoors

Don't go out unless you have to. Keep air conditioning or a fan on and the shades drawn. If your home isn't cool enough, head to public spaces that are: libraries, shopping malls, indoor tracks or senior centers are good options. Ask loved ones or neighbors to pick up groceries or medications, if needed, or have them delivered if that's available to you.

Adjust Your Exercise Routine

Watch the weather forecast, looking not only at actual temperature but also humidity and "real feel" (what the temperature actually feels like). If it's too hot, move your exercise indoors. Otherwise aim for early morning or late evening, when it's coolest.

If you do exercise outdoors, cut back temporarily by working out for less time and at less intensity. Find shade, take lots of rest breaks and drink lots of water. Pool or water exercise are great options for outdoor exercise, if available.

Wear Cool Clothing

Look for loose, lightweight, moisture-wicking fabrics. Lighter colors are less likely to soak up heat. You can also try cooling garments, some of which hold ice packs. Soak a bandana or other garment in cool water and wrap it around your neck.

Get Creative

Carry a handheld, battery-operated fan or wear one around your neck. Attach a spray bottle or carry one separately so you can mist your face and cool your skin. Take cool or lukewarm showers or baths when you return from outside.
