Common Warning Signs
Before fainting, many people experience a range of symptoms like lightheadedness, nausea, or a sudden feeling of warmth or cold. These symptoms are your body's way of signaling that a reflex syncope episode might be imminent. Recognizing these signs early can help you take action to prevent a fall.
The Role of Triggers
Certain triggers can lead to reflex syncope, especially in younger people. Emotional stress, dehydration, or standing for long periods are common culprits. Identifying and avoiding these triggers can reduce the risk of an episode. Sometimes, the symptoms are so subtle that they go unnoticed, particularly in older adults.

After the Episode: What Happens?
After a syncope episode, many people feel fatigued or washed out. This post-episode fatigue is a common symptom and can last several minutes to hours. Knowing this can help you plan for rest and recovery, minimizing the impact on your daily activities.
