8. Make sure to consume an adequate amount of water daily
Drinking water is the solution to almost all health issues. Increased intake of water will keep you hydrated during the day and therefore rejuvenate a lethargic brain. The cells of the brain require twice as much energy than other cells of the body and water is the most effective provider of this energy. When the brain has an adequate supply of water, you will think faster and be more focused, and have greater creativity and clarity.
Medical professionals suggest that the average human should be consuming about 64 ounces of water every day. That is closely equal to 8 glasses of water or 4 plastic bottles of water. Lack of water to the brain can cause numerous problems associated with focus, memory, and brain fatigue, as well as sleep issues, headaches, depression, anger, and more.
What to do: Carry a bottle of water around with you can see how many times a day you can fill it up. Drink teas or foods with high water content, like watermelon or celery. Keep track of your water intake and make drinking water a priority.
