Types of stress
There are several types of stress, including: acute stress episodic acute stress chronic stress.
Acute stress Acute stress happens to everyone. It’s the body’s immediate reaction to a new and challenging situation. It’s the kind of stress you might feel when you narrowly escape a car accident. Acute stress can also come out of something that you actually enjoy.
It’s the somewhat-frightening, yet thrilling feeling you get on a roller coaster or when skiing down a steep mountain slope. These incidents of acute stress don’t normally do you any harm.
They might even be good for you. Stressful situations give your body and brain practice in developing the best response to future stressful situations. Once the danger passes, your body systems should return to normal.
Severe acute stress is a different story. This kind of stress, such as when you’ve faced a life-threatening situation, can lead to post-traumatic stress disorder (PTSD) or other mental health problems.
Episodic acute stress Episodic acute stress is when you have frequent episodes of acute stress. This might happen if you’re often anxious and worried about things you suspect may happen. You might feel that your life is chaotic and you seemingly go from one crisis to the next.
Certain professions, such as law enforcement or firefighters, might also lead to frequent high-stress situations. As with severe acute stress, episodic acute stress can affect your physical health and mental well-being.
Chronic stress When you have high-stress levels for an extended period of time, you have chronic stress.
