5. Dehydration
Our bodies consist of 70% water. So it is easily understandable that water is necessary for every bodily function including brain functions. Lack of water in the body is termed as dehydration. Dehydration can affect the brain very quickly. A decrease in cognitive functions can occur due to two hours of heavy excise without water. Different studies have shown that dehydration affects various functions like coordination, complex problem-solving, and attention.
You don’t need to remind yourself about drinking a certain amount of water every day. You just need to drink water when you are thirsty as thirst is a good indicator of the need for water. It is a good habit to drink water throughout the day to keep the body and brain healthy.
