Depression

Energy, Sleep & Stress Care
Written By Jennifer Tang

Overview

Depression is a common but serious mental health condition that can affect mood, interest and enjoyment, energy, sleep, appetite, concentration, relationships, and everyday functioning. It is different from temporary sadness. During a depressive episode, low mood or loss of interest typically persists most of the day, nearly every day, for at least two weeks and is accompanied by other symptoms.¹˒²

At Tangible Health, we take a whole-person approach by looking at your mood symptoms, sleep, nutrition, physical activity, stress, medications and supplements, medical conditions, and overall function. Naturopathic care can complement established treatments such as psychotherapy and medication while supporting broader aspects of physical and emotional health.²˒⁴

What Is Depression?

Depression is a mood disorder involving persistent low mood and/or a loss of interest or pleasure in activities, together with other emotional, cognitive, behavioural, or physical symptoms that interfere with everyday life. Symptoms can range from mild to severe.¹ Several depressive patterns can occur:

Major Depressive Disorder
Major depression involves depressed mood or loss of interest accompanied by other symptoms for at least two weeks, with meaningful effects on daily functioning.¹˒⁴

Persistent Depressive Disorder
This involves depressive symptoms that persist for an extended period, generally two years or longer in adults. Symptoms may be less intense than an acute major depressive episode but can still significantly affect quality of life and functioning.⁴˒⁵

Seasonal Pattern Depression
Some people experience recurrent depressive episodes during a particular season, most commonly beginning during fall or winter and improving during spring or summer.⁶ Depressive episodes can also occur as part of bipolar disorder. A history of periods involving unusually elevated or irritable mood, substantially increased energy or activity, reduced need for sleep, increased talkativeness, impulsivity, or other symptoms of mania or hypomania is clinically important because bipolar depression requires a different treatment approach.¹˒⁵

Common Symptoms of Depression

Depression can affect emotional, cognitive, physical, and behavioural health.¹˒⁴

Emotional Symptoms

  • Persistent sadness, emptiness, or low mood

  • Loss of interest or pleasure

  • Feelings of hopelessness, guilt, or worthlessness

  • Irritability

  • Feeling emotionally numb or disconnected

Cognitive Symptoms

  • Difficulty concentrating or making decisions

  • Reduced motivation

  • Forgetfulness or mental slowing

  • Repetitive negative thoughts

  • Thoughts about death or suicide

Physical & Behavioural Symptoms

  • Fatigue or low energy

  • Difficulty sleeping or sleeping excessively

  • Changes in appetite or weight

  • Feeling physically slowed down or restless

  • Social withdrawal

  • Reduced self-care

  • Difficulty managing work, school, or everyday responsibilities

Not everyone experiences depression in the same way. For some people, fatigue, irritability, sleep changes, physical symptoms, or loss of interest may be more noticeable than sadness.¹

Causes & Contributing Factors

Depression does not have one single cause. Biological, psychological, social, medical, and environmental factors can interact in different ways for different people.¹˒²

Life Experiences, Stress & Mental Health
Bereavement, trauma, relationship difficulties, financial stress, loneliness, illness, caregiving demands, and other major life experiences can contribute to depression. Anxiety, trauma-related conditions, substance-use concerns, and other mental health conditions may also overlap with depressive symptoms.¹

Sleep & Daily Health
Sleep disruption is common in depression and can affect energy, concentration, mood, and daily function. Nutrition, physical activity, social connection, alcohol or substance use, and daily routines may also influence overall wellbeing and recovery.¹˒⁴

Medical Conditions & Medications
Certain medical conditions and medications can contribute to symptoms that resemble or worsen depression. Depending on the individual presentation, targeted evaluation for concerns such as thyroid disease, anemia, medication effects, or sleep disorders may be appropriate.³

Pregnancy, Postpartum & Life-Stage Changes
Depression can occur during pregnancy, after childbirth, or during other significant life-stage changes. Hormonal changes may be relevant for some people, but depression should not automatically be attributed to a general “hormonal imbalance.”

Our Approach to Depression

At Tangible Health, we focus on understanding how depression is affecting your life and which physical and lifestyle factors may be useful to address alongside appropriate mental health treatment.

Your Mood & Daily Function
We review when symptoms began, mood patterns, loss of interest, motivation, concentration, energy, daily routines, relationships, work or school functioning, and how much symptoms are interfering with everyday life. Assessment also includes safety, previous depressive episodes and treatment, family mental health history, and any symptoms that could suggest bipolar disorder or another mental health condition.

Your Sleep, Nutrition & Overall Health
We review sleep, eating patterns, physical activity, stress, medications and supplements, alcohol and substance use, physical health, and other symptoms that may provide useful clinical context. The goal is not to search for a hidden gut, adrenal, hormonal, inflammatory, or nutritional explanation for depression. Instead, we identify specific modifiable factors or medical concerns that may reasonably contribute to your overall wellbeing and treatment response.

Your Goals
Your goals may include improving mood, reconnecting with activities you enjoy, sleeping more consistently, increasing energy, improving concentration, returning to exercise, supporting nutrition, managing medication side effects, or integrating naturopathic care with psychotherapy or medication. Care is built around your priorities, existing treatment, symptom severity, and safety.

Treatments That May Be Included

Psychotherapy and medication are established treatments for depression, with treatment selected according to symptom severity, previous response, health history, personal preferences, and safety considerations.³˒⁴˒⁸ Cognitive behavioural therapy and related evidence-based psychological approaches are also available through mental health services in Ontario.⁷

Your supportive care plan may include:

  • Naturopathic Counselling to support coping, health behaviour change, stress management, routines, and implementation of your broader mental health plan

  • Lifestyle Medicine to support physical activity, sleep, daily structure, social connection, and other behaviours that may support overall wellbeing

  • Clinical Nutrition to support regular meals, adequate nutrition, and individualized dietary needs

  • Nutraceuticals & Supplements when there is a specific nutritional or clinical indication and safety and medication interactions have been reviewed

  • Botanical Medicine in selected circumstances, with careful consideration of evidence, side effects, mental health history, and medication interactions

  • Medication & Supplement Review to identify possible contributors to fatigue or mood symptoms and reduce the risk of interactions with antidepressants or other psychiatric medications

  • Collaborative Care with your family doctor, psychologist, psychotherapist, counsellor, psychiatrist, or other healthcare professionals when appropriate

Lifestyle and naturopathic strategies are intended to complement appropriate mental health treatment, not replace psychotherapy or medication when these are indicated.³˒⁸˒¹⁰

What to Expect

Initial Assessment
We begin with a detailed review of your mood, interest and enjoyment, sleep, energy, appetite, concentration, stress, daily function, medications and supplements, medical history, previous mental health treatment, and current supports.

Mood & Health Assessment
We consider symptom severity, duration, safety, previous depressive episodes, and other conditions that may overlap with depression. When the history suggests it, targeted medical assessment may also be appropriate for concerns such as thyroid disease, anemia, medication effects, or sleep disorders.³

Personalized Plan
Your plan is developed around your symptoms, existing treatment, sleep, nutrition, physical activity, health history, and personal goals. Recommendations are designed to complement psychotherapy or medical treatment when needed.

Ongoing Support
Follow-up focuses on changes in mood, interest and enjoyment, sleep, energy, daily function, treatment response, and progress toward your goals. Worsening symptoms or new safety concerns may require additional mental health support.

When to Seek Support for Depression

Consider speaking with a healthcare provider or mental health professional if:

  • Low mood or loss of interest persists for two weeks or longer

  • Depression is affecting work, school, relationships, or everyday responsibilities

  • You feel persistently hopeless, worthless, or guilty

  • Sleep or appetite has significantly changed

  • Fatigue or difficulty concentrating is persistent

  • You are withdrawing from relationships or activities

  • You are increasingly using alcohol, cannabis, or other substances to cope

  • Symptoms keep returning

  • Current depression treatment is not providing enough relief

  • You have experienced periods of unusually elevated mood, decreased need for sleep, markedly increased energy, or impulsive behaviour¹˒⁵

Seek urgent mental health or medical care if:

  • You have thoughts of suicide or self-harm

  • You have made plans to harm yourself

  • You feel unable to keep yourself or someone else safe

  • You are unable to care for basic needs because of severe depression

  • You experience hallucinations, delusions, severe confusion, or major changes in behaviour

  • Depression is accompanied by severe agitation or other rapidly worsening mental health symptoms

Depression can increase the risk of suicide, so changes in safety should always be taken seriously.

Frequently Asked Questions

  • Sadness is a normal emotion and often changes as circumstances change. Depression involves a more persistent pattern of low mood and/or loss of interest alongside other symptoms that affect daily functioning, typically lasting at least two weeks during a depressive episode.¹

  • Depression is not adequately explained by one simple chemical imbalance. Current understanding recognizes a complex interaction of biological, psychological, social, and environmental factors.¹

  • Diagnosis is based on symptoms, their duration and severity, their effect on everyday function, medical and mental health history, and consideration of other possible explanations. There is no single blood test or brain scan that diagnoses depression.⁵

  • Sometimes. Testing should be guided by your symptoms and health history. For example, anemia and thyroid disease can produce overlapping symptoms and may warrant investigation when clinically appropriate, but broad hormone or nutrient panels are not automatically required.⁵

  • No. Treatment depends on the type and severity of depression, previous treatment, personal preferences, other health conditions, and safety considerations. Psychotherapy and medication are both established treatments, and they may be used separately or together.³

  • Yes, physical activity can be a useful part of treatment for some people and is supported in Canadian depression guidance. It can be used alongside psychotherapy, medication, and other treatments according to symptom severity and individual preference.³

  • Yes. Seasonal affective disorder is a form of depression with a recurring seasonal pattern, most commonly beginning in fall or winter and improving during spring or summer.⁶

  • Some complementary treatments have been studied, but effectiveness varies and they are not appropriate substitutes for necessary treatment, particularly in severe depression. Supplements and herbal medicines can also cause side effects and interact with psychiatric medications, so they should be considered individually.⁹

  • Naturopathic care can support sleep, nutrition, physical activity, stress management, medication and supplement review, and assessment of relevant physical-health concerns. It is best integrated with appropriate psychotherapy, medication, or specialized mental health care when these treatments are indicated.
