what cause one to be tired in the afternoon
These may offer short-term peaks in energy, but donât fix the cause. Afternoon fatigue is commonly caused by poor sleep, improper diet, lack of exercise, dehydration, medications or hormonal imbalances. Not getting enough sleep is one of the most common causes of afternoon fatigue. Going to bed too late, getting interrupted by a pet or baby at night, or sleeping on an uncomfortable mattress can all lead to restless sleep.
