Yes, feeling fatigued and drowsy after experiencing strong emotions like anger is relatively normal. Emotions can trigger physiological responses in the body, and anger, in particular, can lead to the release of stress hormones like adrenaline and cortisol. These hormones prepare your body for a "fight or flight" response, which can lead to increased heart rate, heightened alertness, and tense muscles.
Once the intense anger subsides, there is often a rebound effect where the body's systems return to a more relaxed state. The drop in adrenaline and other stress hormones can cause you to feel tired or drowsy, similar to how you might feel after a period of physical exertion.
Additionally, strong emotions can be mentally draining, as they consume a lot of mental energy and attention. This can also contribute to feelings of fatigue.
It's important to note that individual reactions to emotions can vary, so while it's common for some people to feel fatigued and drowsy after anger, others might experience different reactions. If you find that these feelings persist or interfere with your daily functioning, it's a good idea to seek support from a healthcare professional or therapist to explore the underlying causes and coping strategies.
