When you're preoccupied with many different tasks and responsibilities at work, it's difficult to remember to keep hydrated. However, staying hydrated is one of the most important things you can do for your body, as water helps to regulate your internal temperature, remove metabolic wastes, lubricate your joints, and keep your heart and muscles healthy. Studies have shown that those who maintain good hydration have improved alertness, better concentration, and overall enhanced cognitive performance compared with those who are dehydrated; this can also offset potential safety risks, in particular when driving a vehicle.
