What is the recommended amount of water to drink in a day?
According to The U.S. National Academies of Sciences, Engineering, and Medicine, the average healthy adult living in a temperate climate needs to drink approximately:
    - 15.5 cups (3.7 liters) of fluids a day for men
    - 11.5 cups (2.7 liters) of fluids a day for women
This amount is not the same for everyone, since the recommended amount of water to drink per day depends on a variety of factors, such as the temperature or season, how active you are, your gender, your diet and any health conditions you might have. You are probably drinking enough water if:
    - You rarely feel thirsty
    - Your urine is colourless or light yellow
If you feel like you might not be drinking enough water, you can try having water with each meal; before, during and after excercise; or whenever you feel thirsty. If you want to know more about your personal fluid intake based on your physiology and lifestyle, you should consult your doctor or dietician.
What are the symptoms of drinking too little?
Drinking too little water can lead to dehydration, which can cause the following symptoms:

- Thirst: This is the most obvious sign of dehydration. When the body is dehydrated, it signals the brain to release the thirst mechanism.
- Dry mouth, skin, and eyes: Dehydration can lead to a decrease in saliva production, which can result in a dry mouth, skin, and eyes.
- Fatigue: Dehydration can cause fatigue, dizziness, and a decrease in energy levels.
- Dark-colored urine: Urine should be light yellow in color. If it is darker, it may indicate dehydration.
- Headache: Dehydration can cause headaches, especially in people who are prone to migraines.
- Constipation: Dehydration can cause hard, dry stools and constipation.
- Muscle cramps: Dehydration can cause muscle cramps, especially in people who engage in physical activity.

It is important to note that even mild dehydration can affect your physical and mental performance, so it is important to stay properly hydrated by drinking enough water throughout the day.
