One of the main causes of drowsiness is dehydration.. Nutritionists say - all day, without waiting for thirst, you should drink plenty of water, especially in the morning.

For other drinks, doctors recommend citrus juices and green tea.. They invigorate more coffee.

“Natural orange juice is rich in vitamin C, which fills the body with energy, and the smell of orange, lime and lemon stimulates brain activity.

Well, green tea in terms of caffeine content is in no way inferior to a cup of freshly brewed coffee, but it’s much more useful, ”the doctor said.

Great snack at work - unsweetened fruits and berries. These are natural stimulants, “dark” berries - blueberries, currants, cherries are especially good. Out of season, you can add sugar-minted berries to tea or beat frozen in a blender and dilute them with water to get vitamin fruit juice.
