Feeling your heartbeat increase while talking to others, especially when your ECG is normal, is commonly due to anxiety or social anxiety, where the body's natural fight or flight response gets triggered in social situations. This can cause symptoms like a fast heartbeat, sweating, or nervousness, even though the heart itself is healthy. You can manage this by practising relaxation techniques such as deep breathing, gradually exposing yourself to social situations to build confidence, maintaining regular sleep and exercise, and reducing caffeine intake. It can also help to talk to a counsellor or psychologist for techniques like cognitive behavioural therapy (CBT). If symptoms are severe or affecting your daily life, a doctor may suggest medications along with therapy for better control.

Poor memory, anxiety, and lack of concentration are often linked to stress, lack of sleep, poor diet, or mental health conditions like anxiety or depression. The first step is to improve daily habits; get 7-8 hours of good sleep, eat a balanced diet, stay physically active, and reduce screen time and caffeine. Simple techniques like making to-do lists, breaking tasks into smaller steps, and practising relaxation methods such as deep breathing or meditation can help improve focus and reduce anxiety. Staying socially connected and taking regular breaks during work or study also supports better concentration. If these symptoms are persistent or affecting your daily life, it is important to consult a doctor or mental health professional, who can evaluate the cause and suggest appropriate treatment, including counselling or medication if needed.

Brief episodes of lightheadedness and a feeling of suffocation that last 15?20 minutes and worsen when you focus on them are often seen in Panic attack or anxiety-related breathing patterns, though other causes like low blood sugar or BP changes can contribute. Try slow deep breathing (inhale 4 seconds, exhale 6?8 seconds), sit or lie down, and avoid overthinking during the episode; regular exercise, good sleep, and reducing caffeine also help.
