Dear Welcome to HCM We understand your concerns I went through your description. Feeling hot even in low temperature is not that typical. This condition might indicate some organic and internal disorder. First is overweight and excess fat tissues (high BMR (basal metabolic rate)). The fat beneath the skin acts as an insulation barrier which provides warmth.The best way to tackle this would be to lose weight.By regular exercise you can control your hypertension too. Second reasons could be an inborn tendency or hormonal imbalance like hyperthyroidism. For confirmation please visit a general physician and go with his advice. Hope this answers your query.
