Depression and symptoms of depression

Depression is a complex condition that affects millions of people around the world. According to the World Health Organization (WHO), more than 280 million people are currently living with depression (https://www.who.int/news-room/fact-sheets/detail/depression), which makes it one of the most common mental disorders globally.

When we talk about depression, we usually think of emotional symptoms - sadness, listlessness, a feeling of emptiness or loss of interest in activities that used to bring pleasure.

However, the symptoms of depression are not only psychological.

Many people first notice changes in their body - constant fatigue, muscle aches, sleep disturbances or digestive problems - before realizing that these changes are related to depression.

Research shows that as many as 60-80% of people with depression also report pronounced physical symptoms, which indicates a strong connection between the body and the emotional state.

Understanding the symptoms of depression, including physical symptoms, can help recognize the condition earlier and seek appropriate support.

What are the physical symptoms of depression?

Physical symptoms of depression are physical changes that occur as a result of long-term stress, emotional stress and changes in the functioning of the nervous system.

The brain and body are connected through complex neurobiological processes. When a person is depressed, there are changes in the level of neurotransmitters such as serotonin, dopamine and noradrenaline.

These changes may affect:

• energy level
• sleep quality
• appetite regulation
• feeling of pain
• functioning of the immune system
  

That is why depression often has strong physical manifestations.

The most common physical symptoms of depression

Chronic fatigue and lack of energy

One of the most common symptoms of depression is a constant feeling of exhaustion.

People with depression may feel tired even after a long sleep. Simple everyday activities can become very demanding.

Studies show that more than 90% of people with depression report severe fatigue and low energy.

Sleep disorders

Depression often affects sleep quality.

The most common problems include:

• insomnia
• early morning awakening
• hypersomnia (excessive sleeping)

According to research by the American Academy of Sleep Medicine, about 75% of people with depression have a problem with insomnia.

Changes in appetite and body weight

Depression can cause significant changes in eating habits.

Some people experience increased appetite and overeating, while others lose interest in food.

The US National Institute of Mental Health states that changes in appetite and body weight are present in about 40% of people with depression. Source: https://www.sleepfoundation.org/mental-health/depression-and-sleep

Body aches and body tension

Many people suffering from depression also have unexplained body pains, such as:

• headaches
• back pain
• muscle pain
• feeling of tension in the body

Research shows that people with depression have a significantly lower pain tolerance threshold, which can increase feelings of physical discomfort.

In the Mindfulness approach, the body is seen as a place where experiences and emotions are stored. Modern research also indicates that the body actively participates in the way we experience depression.

Digestive problems

Depression can also affect the digestive system.

The most common ones are:

• nausea
• prison
• diarrhea
• stomach discomfort

The connection between the brain and the digestive system is called the brain-gut axis. Scientific research shows that changes in mood can directly affect the function of the digestive system.

Decreased sex drive

Loss of interest in sex is a common symptom of depression.

Studies show that between 50% and 70% of people with depression report decreased libido.

Weakened immune system

Chronic stress and depression can weaken the immune system.

According to research published in the journal Psychological Bulletin, long-term depression can increase the level of inflammatory processes in the body, which affects the body's resistance.

How to recognize depression in time

Physical symptoms of depression are often the first signal that something is out of balance.

It is important to pay attention if they occur for a long time:

• chronic fatigue
• sleep disorders
• body aches without a clear cause
• changes in appetite
• energy loss

If these symptoms persist for more than two weeks, talking to a mental health professional is recommended.

A holistic approach to relieving symptoms of depression

Contemporary approaches to mental health increasingly emphasize the importance of working with the body.

Mild physical activity can help to:

• activates the nervous system
• increase energy levels
• reduce body tension
• improve your mood

Yoga, conscious movement and breathing exercises they can contribute to the regulation of the nervous system and restore a sense of balance.

Mindfulness and depression

Mindfulness is now widely used as a support in the treatment of depression.

In Great Britain, the Mindfulness Based Cognitive Therapy (MBCT) program is implemented in a number of clinical centers, including Oxford University.

A meta-analysis published in JAMA Psychiatry shows that MBCT can reduce the risk of depression recurrence by about 31–43%. Source: https://jamanetwork.com/journals/jamapsychiatry/fullarticle/2517515

In people who have had depression before, the probability of a repeat episode can be between 70% and 80%.

Mindfulness helps people develop a greater awareness of thoughts, emotions and bodily sensations, thus creating space for a different attitude towards stress.

When to seek help

If you or someone close to you is experiencing symptoms of depression, it is important to know that help is available.

Talking to a psychologist, psychotherapist, or other health professional can be the first step toward recovery.

Depression is a treatable condition – and recognizing the symptoms is the first step.
