What is stress?

Stress is the feeling of pressure when you can’t handle your work. Normal stress can motivate you, but high stress can give you mental issues.

What are the three types of stress?

1. Acute Stress:

It is a short-term mental condition that can come because of short-term trauma that comes into your life, like worrying about exams, accidents, arguments with loved ones, losing important things, presentations in front of the boss, etc. The time duration of this stress is 3 days to one month.

  • Acute stress symptoms:

The symptoms are anxiety, trouble sleeping, avoidance behaviors, fast heart palpitations, problems with breathing, and flashbacks.

  • Acute stress treatment:

The solution to this stress is easy: you can meditate, do Prayaram (breathing exercises), do CBT, do physical activities, eat a healthy diet, and talk and connect with others. If you have thoughts about suicide, then take the immediate step of contacting a doctor, and CBT is a very good option.

2. Episodic acute stress:

Episodic acute stress is acute stress that comes back again and again; it is due to work pressure, negative self-talk, financial problems, unhealthy relationships, perfectionist attitudes, high expectations, etc.

  • Episodic acute stress symptoms:
  • The symptoms are anxiety, mood swings, and irritability. Common triggers include work pressure, relationship conflicts, and financial issues. It can be converted into chronic stress if it is not properly treated.

  • Episodic acute stress treatment:
  • To treat anxiety, try CBT, maintain a healthy lifestyle, break your overthinking with the 4-4-4 rule, exercise regularly, and enjoy activities.

    3. Chronic stress:

    Chronic stress means a long duration of tension and worries, which occur due to work pressure, traumatic experiences, health issues, old trauma, and unhealthy relationships. Acute stress runs for short periods, but chronic stress keeps the body alert — fight or flight. This stress increases cortisol.

    • Chronic stress symptoms:

    It gives you so many mental and physical health issues like depression, anxiety, increased blood pressure, heart diseases, hypertension, migraine, headaches, sleeping disorders, irritation, and sexual dysfunction. This stress may include childhood problems or today’s life stress.

    • Chronic stress treatment:

    The solution is exercise, proper sleep, yoga, meditation, keeping a distance from phones and social media, reducing caffeine and junk food, and avoiding self-isolation. If you ignore this stress, then it can create mental as well as physical issues.

    Physical symptoms of stress:

    Physical symptoms are headache, body pain, restlessness, digestive issues, muscle tension, fatigue, and changes in appetite or sleep patterns.

    How to stop stress?

    It is important to manage stress because it can affect emotional, physical, and behavioural health. Self-care is the first step to being safe from stress; good rest, a balanced diet, regular exercise, and relaxation techniques like meditation or yoga can help.

    Keep in contact with your friends and relatives. Avoid unhealthy habits, such as alcohol. Think positively, be proactive and grateful, and help others.

    What is anxiety?

    Anxiety is a natural response involving fear or worry during stressful or challenging situations. When your body senses a threat or danger, it automatically switches to “fight or flight” mode. Due to that, your heart rate increases, muscles tense, and the mind becomes alert. Little anxiety is normal, like before exams or public speaking. But if it is kept for a long time, then it becomes an anxiety disorder.

    What are all the types of anxiety?

    1. Generalized Anxiety Disorder (GAD):

    It is a mental health issue in which people feel fear about daily small and uncontrolled things. The signs of this are muscle tension, headache, nausea, grouchiness, and sweating; the patient does not properly concentrate. GAD is connected to genetic, biological, and environmental influences. If any patient is worried for more than 6 months and faces a physical problem, it is diagnosed. If you don’t take treatment on time, then it becomes chronic, so you should seek professional help.

    2. Selective mutism:

    It is an anxiety disorder where patients feel extreme anxiety while talking to others. Most children face this issue: they speak in familiar environments (school and home) but do not speak in social situations. This problem can also occur with other psychiatric disorders like generalized anxiety disorder. Selective mutism can be treated through cognitive-behavioural therapy, where the patient practices how to face the fear.

    3. Separation Anxiety Disorder:

    It is a condition in which the patient fears being disconnected from a close attachment figure. This problem affects both children and adults. This illness causes emotional distress and effort to avoid being separated; the patient also faces headaches—treatment like therapy and medication help to manage its symptoms and make daily life better.
