Mental or Physical Fatigue? Know the Difference—And What to Do About It


How To Tell The Difference Between Mental vs. Physical Fatigue

Fatigue is one of the most common complaints in clinical practice, but not all fatigue is the same. Understanding the difference between mental and physical fatigue is key to knowing when and how to seek support.

🌀 “If weekends reset you, it's probably mental.”

Mental fatigue is often the result of prolonged cognitive demand, from decision-making, to multitasking, performance pressure, and constant connectivity. It's common in high-functioning individuals with demanding workweeks. A telltale sign: you feel significantly better after a weekend of rest or time away from screens, the office and structure. Mental fatigue usually lifts when the demands that caused it subside.

🪫 “Still tired after resting? It's time to look deeper.”

Physical fatigue, on the other hand, tends to linger, even with adequate rest. If you’re still tired after a restful weekend, it's a signal to dig deeper. Causes may include low nutrient levels (such as B12, iron, or vitamin D), chronic inflammation, insulin resistance, thyroid dysfunction, or hormonal shifts related to peri-menopause or menopause.

These types of fatigue are rooted in biochemistry and typically don’t resolve with rest alone.

A naturopathic approach looks at both the mental and physical drivers of fatigue. Through targeted lab testing, personalized nutrition, and support for the nervous and endocrine systems, we work to identify and correct the root cause.

If your fatigue isn’t improving with time off, it may be time for a deeper look.


Do You Need An Adaptogen? What the Research Says

Adaptogens are popular natural remedies for stress, but solid clinical evidence exists for only a few. Chief among them? Ashwagandha and Rhodiola.

Ashwagandha supports the stress response by lowering cortisol levels through its effects on the HPA axis. It does 3 things really well: enhances mood, reduces anxiety and improves sleep. It may also curb stress-related eating behaviours like binging and food cravings. It supports cognitive recovery after stress and can improve sexual function in women. It has a long half-life in the body, meaning that dosing once a day is likely sufficient to be helpful.

Rhodiola on the other hand reduces physical fatigue, supports stamina, and improves mental clarity when under a lot of pressure at work or school. It helps maintain mental performance and energy while addressing underlying stressors. Because it has a shorter half-life in the body, multiple daily dosing may be required to maintain its effect.

“Choosing the right adaptogen, at the right dose, can make a dramatic difference in lifting mental fatigue, improving stamina, or easing anxiety.”

Before you start an adaptogen, consult your ND. Many products contain too little to be effective—a practice known as “fairy dusting.” Personalized care ensures safe, effective support.

Hi! I'm Dr. Dominika Zarzeczny, ND

First inspired by the work of Dr. Gabor Mate, Dr. Dominika has focused much of her career on helping her patients connect the dots between early adversity and trauma and their impact on lifelong health and well-being. She knows that the reversal of chronic illness involves the nervous system, and so she has dedicated her practice to helping patients master their own nervous system to positively influence their mind and body, behaviours and ultimately health outcomes. Her explanation of disease doesn't pathologize or blame, but is nuanced, humanized and filled with hope. She trained with various psychologists and experts in the field of psychological trauma. She incorporates the principles of neuroscience, attachment theory, mindfulness, Polyvagal Theory and compassionate inquiry in her approach with patients. Combining these with her naturopathic training, she likes to say that she works at the intersection of science and human experience.
