Stress symptoms aren’t always obvious, and they’re often misunderstood or misinterpreted.

Here are five frequently overlooked signs of stress:

Digestive issues

When stress hits, your body releases neurotransmitters, chemical messengers that trigger the body’s fight-or-flight response. This can disrupt the digestive system, leading to gastrointestinal issues such as nausea, stomach pain, constipation, and diarrhea.

Headaches

When you’re stressed, your nervous system causes the muscles in your neck, shoulders, and scalp to contract. Over time, this can reduce blood flow and send pain signals to the brain. Tension headaches are often described as a dull ache or a tight band around the head, with heightened sensitivity in the temples, scalp, and the base of the neck.

Skin problems

When you experience prolonged stress, elevated cortisol levels can cause your immune system to go into over-drive. This hormonal shift can trigger hives and rashes, and cause existing inflammatory conditions, like rosacea, psoriasis, and eczema, to flare up.

Frequent illness

Long-term stress can weaken the body’s defenses, leaving you more susceptible to illness. This is because stress hormones suppress immune cell function, reduce antibody production, and increase inflammation.

Brain fog

When your stress levels remain high, cortisol can impact the prefrontal cortex, the part of the brain responsible for rational thought, decision-making, and memory. As a result, you may struggle to think clearly and stay focused.

Managing stress

While it’s impossible to avoid stress altogether, you can learn to manage it. Many people find that being active boosts their mood and provides a welcome distraction from their worries. Others find that mindfulness helps them to focus on the moment and untangle themselves from unhelpful thought patterns. Build a few stress-management techniques into your routine, and you may find difficult times are easier to cope with.

When stress becomes chronic (meaning it’s constant and prolonged) it can begin to take a serious toll on your physical and mental wellbeing. If stress is impacting your daily life, speak to your healthcare provider as soon as possible.
