Stress is a biological response that affects nearly every system in your body. The first step to managing it is actually recognising it in the first place. Many people don’t even consider stress to be a problem and go through their lives as if it is a new normal for their body and mind.

A 2025 study reported 35.1% prevalence of stress, higher in women (36.1%) and high-income nations (36%).

How Does Stress Affect the Body?

Stress triggers a “fight-or-flight” response. Your body releases hormones like cortisol and adrenaline, which prepare you to react to a threat. Short-term, this is useful. Long-term, it is damaging.

Physical Effects of Stress

When stress hits, your body reacts immediately. Here is what happens:

• Heart rate and blood pressure increase
• Muscles tighten, especially in the neck, shoulders, and back
• Breathing becomes faster and shallower
• Digestion slows down or becomes irregular
• The immune system becomes suppressed over time

According to the research, when you face too much stress, it puts you at risk of some serious physical conditions. It can include heart conditions and blood pressure issues.

How Does Stress Affect the Mind?

Stress impairs memory, decision-making, and emotional regulation. It can lead to anxiety and depression if left unaddressed.

Mental and Emotional Effects

The psychological toll of stress is just as serious as the physical one. Your brain changes under chronic stress.

• Difficulty concentrating or making decisions
• Increased irritability, mood swings, and anger
• Feelings of overwhelm, helplessness, or hopelessness
• Persistent worry and racing thoughts
• Reduced motivation and creativity

What Are the Common Symptoms of Stress?

It is completely normal to feel a bit “frazzled” when life gets intense, but stress is a bit of a shapeshifter. It doesn’t just stay in your head.

It often shows up in your body and behaviour before you even realise you’re overwhelmed.

Physical Symptoms

• Aches and Pains: Frequent headaches, muscle tension (especially in the neck and shoulders), or chest pain.

• Digestive Issues: Nausea, diarrhoea, or constipation (your gut is very sensitive to stress hormones).

• Low Energy: Feeling exhausted even if you’ve slept, or having trouble falling asleep at night.
• Frequent Illness: Stress can weaken your immune system, which means you might get ill multiple times.

Emotional and Behavioural Symptoms

• Anxiety and constant worry
• Social withdrawal
• Changes in appetite (eating too much or too little)
• Increased use of alcohol, tobacco, or other substances
• Procrastination and neglecting responsibilities

Note: If you’re experiencing physical pain, especially chest pain or severe shortness of breath, don’t just chalk it up to a “busy week.” It’s always best to get a quick check-up with a doctor to be safe.

Can Stress Cause Long-Term Health Problems?

Yes. Chronic stress is directly linked to serious, long-term health conditions. It is not something to dismiss as “just stress.”

Possible Long-Term Effects

When the body remains in a prolonged state of stress, the damage accumulates. Here are the conditions strongly linked to chronic stress:

• Heart disease and hypertension: Elevated cortisol levels strain blood vessels over time.
• Type 2 diabetes: Stress hormones can raise blood sugar and contribute to insulin resistance.
• Obesity: Cortisol increases appetite and promotes fat storage, especially around the abdomen.
• Gastrointestinal disorders: Irritable bowel syndrome (IBS) and acid reflux are frequently stress-related.
• Mental health disorders: Prolonged stress is one of the leading triggers for clinical anxiety and depression.
• Immune dysfunction: Chronic stress suppresses the immune system, making you more susceptible to infections and slower to heal.
