Causes of Stress and Anxiety: What Triggers Them and What Helps

The most common causes of stress and anxiety are pressures at work or school, money worries, relationship strain, health problems, major life changes, poor sleep, and too little recovery time. Stress is usually a reaction to a specific challenge, while anxiety can linger after the challenge passes. Daily habits, practical problem-solving and professional care can all help.

This guide is for adults and older teens who want to understand where their stress and anxiety come from and what to do about it. It explains the difference between the two, common triggers, practical steps and signs that it is time to talk with a professional. It is educational and does not diagnose anyone.

What is the difference between stress and anxiety?

Stress is usually a response to an outside cause, such as a deadline or an argument, and it tends to ease once the situation is resolved. Anxiety is a persistent feeling of worry or dread that can continue even when there is no clear threat.

The National Institute of Mental Health (NIMH) explains this distinction in its fact sheet I'm So Stressed Out!, noting that both can affect the mind and body. MedlinePlus, from the National Library of Medicine, describes anxiety as fear, dread and uneasiness that becomes a disorder when it is not temporary and can be overwhelming.

What happens in the body during stress?

During stress, the body releases hormones that prepare you to respond to a threat. MedlinePlus explains that stress hormones make the brain more alert, tense the muscles and increase the pulse.

In short bursts, this response is useful. When it stays switched on, people often notice:

• Headaches, muscle tension or jaw clenching
• Stomach upset or changes in appetite
• Trouble falling or staying asleep
• Irritability and trouble concentrating
• Feeling tired but wired

Our article on physical symptoms of stress covers these signs in more detail.

What are the most common causes of stress and anxiety?

The most common sources fall into a few broad groups: work or school, money, relationships, health, life changes and lifestyle. Several often stack up at once, which is when people feel most overwhelmed.

• Work and school: deadlines, heavy workloads, unclear expectations or conflict
• Money: bills, debt, job insecurity or unexpected expenses
• Relationships: family tension, breakups, loneliness or caregiving
• Health: a new diagnosis, chronic pain or a loved one's illness
• Life changes: moving, a new job, a new baby or a loss
• Lifestyle: short sleep, too much caffeine, little movement, constant news

The American Psychological Association (APA) lists common work stressors including excessive workloads, low salaries, few opportunities for growth, and conflicting demands or unclear expectations. If news is a trigger, see doomscrolling and news anxiety.

How do sleep and lifestyle affect stress and anxiety?

Short sleep, too much caffeine and too little movement can make stress and anxiety feel stronger and harder to manage. They are some of the most changeable causes of stress and anxiety, which makes them a good place to start.

The Centers for Disease Control and Prevention (CDC) says adults ages 18 to 60 need at least seven hours of sleep a night, and recommends a consistent schedule, avoiding caffeine late in the day and turning screens off before bed. The CDC also notes that physical activity can help you feel better right away, sleep better and reduce the risk of depression and anxiety.

If worry peaks at bedtime, see why anxiety can be worse at night.

Step by step: how to find your personal stress triggers

The best way to find your own triggers is to track them for a week or two and look for patterns. The APA recommends this approach for work stress, and it works for other areas of life too.

1. Each evening, note your stress level from 0 to 10.
2. Write down what happened when stress spiked: where, who, and what you were thinking.
3. Record sleep, caffeine, alcohol and exercise for the day.
4. After a week, circle the situations that appear most often.
5. Choose one trigger to work on first.
6. Decide on one small change, such as a boundary, a schedule change or a conversation.
7. Review after another week and adjust.

Example: a hypothetical worker might notice that stress spikes every day after checking email late at night, and choose to stop checking after 8 p.m. A week later, they could compare their sleep and morning stress ratings to see whether the change helped.

What helps manage stress and anxiety day to day?

Day-to-day relief usually comes from a combination of body-calming skills, practical problem-solving and connection with others. No single tool works for everyone.

• Slow breathing, with a longer exhale than inhale
• A short walk or stretch break
• Writing a to-do list to get worries out of your head
• Breaking big problems into the next small step
• Setting limits on work messages and news
• Talking with someone you trust

The National Center for Complementary and Integrative Health (NCCIH) notes that relaxation techniques are generally considered safe for healthy people, though some people occasionally feel more anxious while doing them. Stop any exercise that makes you feel worse.

What should you tell a clinician about stress and anxiety?

Tell a clinician what you feel, how long it has lasted, what seems to trigger it, and how it affects your daily life. Specific examples help more than general descriptions.

A short checklist to bring:

• When symptoms started and how often they happen
• Physical symptoms, such as racing heart, stomach upset or headaches
• Sleep, caffeine, alcohol and substance use
• Major life changes in the past year
• What you have already tried, and what helped
• Any thoughts of self-harm

The NIMH notes that psychotherapy and medication are the main treatments for anxiety disorders, used alone or together depending on an evaluation. If you feel drained as well as anxious, read mental exhaustion: signs, causes and recovery.

How can you support someone who is stressed or anxious?

You can support a stressed or anxious person by listening, offering practical help, and gently encouraging care if symptoms last. Trying to argue someone out of their worry rarely works.

What to say:

• "That sounds like a lot. Do you want to talk it through or just vent?"
• "Is there one thing I could take off your plate this week?"
• "Want to go for a quick walk with me?"
• "You have seemed stressed for a while. Have you thought about talking to someone?"

Avoid "Just relax" or "Stop worrying," which can make a person feel dismissed. Practical help, such as watching children for an hour or helping sort a pile of paperwork, often means more than advice.

The NIMH notes that people should seek help when stress or anxiety interferes with daily life. If a loved one is avoiding work, friends or activities because of anxiety, encouraging an evaluation is a caring step, not an overreaction.

When should you get help sooner?

Get help soon if stress or anxiety lasts for weeks, keeps you from working or sleeping, or leads you to avoid important parts of life. The NIMH suggests seeking help when symptoms interfere with daily life, cause you to avoid things, or seem to be always present.

MedlinePlus advises contacting a provider if severe stress symptoms last two weeks or more, and seeking help right away for suicidal thoughts or increased substance use. Also get urgent care for chest pain, fainting or trouble breathing, which need a medical check.

What should Texans know about stress and anxiety?

Texans face some regional stressors, such as long summers of high heat, long commutes in large metro areas and severe weather. Our article on whether Texas heat can make anxiety worse looks at one of these.

Across Texas, 2-1-1 Texas can connect people with community mental health services, and local mental health authorities run 24/7 crisis lines.

Some causes of stress and anxiety in Texas are seasonal, such as summer heat or storm season. Planning ahead, for example by scheduling outdoor activity for cooler hours or preparing a simple storm plan, can make those stretches feel more manageable.
