1) Ayurveda views fatigue as arising from an imbalance of the doshas (Vata, Pitta, Kapha), which can be caused by poor diet, lifestyle factors, and toxin buildup.
2) Managing fatigue involves lifestyle changes like following an appropriate diet for one's constitution, getting adequate sleep, and using herbal remedies and spices to aid digestion and reduce toxins.
3) Physical symptoms of fatigue include body aches, poor immune function, and mental symptoms like lack of motivation; Ayurvedic treatments target the root causes through diet, yoga, self-massage and specific herbs.
