Sleep

Getting a good night’s sleep is one of the most important ways our bodies recharge. It helps us think clearly, stay in a good mood, and keeps our physical health on track. Sleep also strengthens our immune system and helps us stay steady on our feet.

For people with Parkinson’s, sleep can be a challenge. The same brain changes that cause movement issues can also mess with sleep patterns, leading to frequent wakeups and less "deep sleep." When you don't get the rest you need, it can make Parkinson’s symptoms - like tremors or fuzzy thinking - feel worse during the day.

Keeping a regular bedtime routine is a simple but powerful way to help your brain and body function at their best.

Sleep, Circadian Rhythms, and Parkinson’s Disease

Sleep and circadian rhythm disruptions are fundamental to Parkinson’s; stabilizing daily cycles reduces symptom burden and improves overall patient functioning.

Why Body Rhythms Matter in Parkinson’s Disease

Light Therapy for PD

In a recent episode of The Michael J. Fox Foundation Parkinson’s Podcast, Dr. Beatrix Feigl, an Associate Professor at the Queensland University of Technology (QUT), discussed her groundbreaking research into how specific types of light can treat both sleep and motor symptoms in Parkinson’s disease (PD).

GENERAL

The Age-Old Question of Sleep

In a Better Brain Fitness episode, Drs. Josh Turknet and Tommy Wood argue that poor sleep isn't an inevitable part of aging. Instead, they reveal that declining sleep quality is often driven by lifestyle choices we can change, rather than just unalterable biological shifts.

The Hidden Cost of Fatigue

In this episode of StemTalk, Dr. Hans Van Dongen explores how sleep loss fundamentally rewires brain function and biology. He discusses the dangers of chronic sleep restriction, revealing that individuals often fail to recognize their own cognitive decline despite suffering severe impairment comparable to total sleep deprivation. The conversation covers the "local sleep" phenomenon—where neuronal groups shut down during wakefulness—and how this instability disrupts decision-making and metabolic health.

Sleep, Circadian Biology, and Chrono-Nutrition

This atricle is based on an interview with Dr. Greg Potter. It brings together essential ideas about sleep and nutrition cycles, aligning everyday tips with what we know from research. Discover how light, meal timing, and consistent routines can sync your body’s clock to improve rest and overall health.
