Understanding temperature dysregulation in Parkinson’s

Parkinson’s affects the autonomic nervous system, the part of the body that controls automatic functions like:

  • Sweat production, which is important for cooling the body
  • Blood vessel control, which helps release or conserve heat
  • Muscle activity, which can create extra heat when muscles tighten or shake
  • When these systems don’t work smoothly, the body struggles to keep a stable temperature.

Temperature swings can affect comfort, sleep, and daily activities. Heat sensitivity, in particular, can make symptoms like stiffness, slowness, or fatigue feel more intense. For some, exposure to heat or cold can trigger falls, fainting, dehydration, or medical emergencies. Helpful strategies, like staying hydrated, dressing in layers, and planning around hot weather, mean you can stay safer and more comfortable.

Why heating & cooling are medical needs

Because of this physiological impairment, active heating or cooling becomes a medical requirement, not a lifestyle choice. Air conditioning, fans, heaters, and maintaining a stable indoor temperature are often essential to:

  • manage symptoms
  • prevent complications
  • remain safe at home
  • avoid hospitalisation.

This leads to higher-than-average electricity usage, especially during extreme weather, a growing issue as Australia experiences more frequent heatwaves.

Energy subsidies & concessions

If you live with Parkinson’s and struggle to self-regulate body temperature, many Australian states and territories offer energy cost support.

This usually requires:

  • holding an eligible concession card (e.g., Pensioner Concession Card, Health Care Card, DVA Gold Card)
  • a medical certificate from your GP or neurologist confirming your inability to regulate body temperature and the need for heating/cooling at home.

Western Australia (WA): Thermoregulatory Dysfunction Energy Subsidy

Residents with thermoregulatory dysfunction — i.e., clinically significant loss of ability to regulate body temperature — can apply for an annual energy subsidy. Parkinson’s (and other neurodegenerative conditions) can meet eligibility if a doctor certifies it and you hold a concession card.

  • Benefits:
    • ~$810 paid each year directly to your bank account to help cover heating & cooling energy costs.
    • Up to two subsidies per household if two eligible people live at the same address.
  • How it works:
    • Complete the application (online or paper).
    • Your GP or neurologist must complete part of the form confirming your medical condition.

Stay cool this summer!
