Water is essential for the body to function correctly. But how much water should you drink per day?
A commonly suggested answer is eight glasses of water per day. But that might not apply to you – your needs can vary depending on many different factors.
Rather than trying to measure exactly how much fluid you need to consume, it can be more effective to assess your own hydration and fluid loss.
How much water should I drink each day?
There is no one-size-fits-all answer for how much water you should drink. Your total fluid intake depends on several different factors, such as your sex, age, activity levels, the weather, your diet, and your overall health.
You should aim to get most of your fluids from drinking water, but other liquids, and even food, contribute to your total amount.
You may need more fluids if you are:
• Exercising or physically active
• In a hot climate
• Sweating profusely
• Sick with a fever
• Pregnant or breastfeeding
• Spending long periods outside
• Eating a high-salt or high-protein diet
Rather than trying to measure your fluid intake in detail, you can focus on how much you need to stay hydrated.
Is it best to drink water in sips throughout the day?
Yes, it is best to spread out your fluid intake as you go about your daily life.
You can encourage yourself to drink more water by making simple changes to your routine. Having a glass of water when you wake up, having water with your meals, and keeping a water bottle or glass with you at your workplace or while studying are simple ways to ensure that you stay hydrated.
A sample schedule could look like this:
• Water when you wake up
• Water with breakfast
• Water during the morning
• Water with lunch
• Water when exercising
• Water with dinner
• Less water close to bedtime if you find that you need to urinate frequently at night
Is it best to drink water first thing in the morning?
Drinking water when you wake up is a good way to rehydrate after a night’s sleep, and it can help you start your day off right. However, there are a number of myths about the benefits of drinking water first thing in the morning.
Some suggest that drinking water first thing boosts your metabolism, flushes out toxins, or even significantly impacts your hormones. However, there is little evidence to support such claims.
What drinking water does after you wake up is replace the fluids that your body loses throughout the night. You may experience more frequent trips to the toilet if you drink water before bed, which is why water is generally not advisable to drink close to sleep.
Should I drink water with my meals?
Yes, you can drink water with your meals. There is a myth that drinking water with your meals will dilute your stomach acids, preventing you from digesting your food, but it is false. In fact, water can aid in digestion. It can also reduce bloating and promote healthy eating habits by helping you feel full faster – especially if you drink it before you eat.
Therefore, there is no reason for healthy people to avoid drinking water with meals.
How can I tell if I am drinking enough water?
You do not need to be obsessive about measuring your water intake. Your body will often tell you when it needs fluids. The most reliable indicator that you are sufficiently hydrated is your urine. If it is consistently pale yellow, you are well-hydrated. If it is dark yellow, you may need to drink more fluids.
However, some medications, supplements, or diseases can affect the color of your urine. If you notice that your urine is consistently very dark, you should speak to a medical professional.
Another indicator of good hydration is that you generally do not feel excessively thirsty throughout the day. If you feel frequently thirsty, especially in hot weather or when exercising, you may need to drink more fluids. However, this is not always the case – some people, such as the elderly, exercising people, and those with specific health conditions, may experience frequent thirst even when they are well-hydrated.
If you have been exercising and find that you have lost a lot of weight during your session, most of it is likely to be water that you have lost through sweat. Therefore, you should drink more fluids after you finish your workout. People who exercise intensely should pay particular attention to their fluid intake. If you are a competitive athlete who exercises regularly and sweats heavily, you may wish to track your fluid intake more closely rather than relying only on your sense of thirst.
Can I drink too much water?
Yes, in fact, drinking too much water can be dangerous. The issue with drinking too much water is that it can lead to a severe electrolyte imbalance. Your blood can become too diluted, which can cause you to experience a range of unpleasant symptoms, such as headaches, nausea, vomiting, and confusion. In extreme cases, it can even be fatal.
This is another reason why you should not be obsessive about your water intake. Water is essential for your survival, but drinking too much water is not healthy.
The extreme sports and endurance running communities are generally quite aware of the risks associated with both dehydration and overhydration and try to carefully track their fluid intake accordingly.
Does coffee count towards my daily water intake?
Coffee and tea are made from water, so they do count towards your fluid intake. However, they also contain caffeine, a diuretic that increases urine production. Most of the water in coffee and tea is still beneficial, though, and you do not need to drink an additional glass of water for every cup of coffee you consume.
It is still better to prioritize plain water over coffee, since coffee contains calories and other additives that are unhealthy.
Are sparkling waters a good option?
Clear carbonated water can also be used as a source of fluids. If you enjoy drinking sparkling water, you can drink it in preference to sugar-sweetened sodas. However, you should be mindful of flavored sparkling water brands that may contain added sugars and artificial flavors.
How much water should I be drinking when exercising?
Most of your fluid intake should be determined by your general needs. However, you may require more fluids when exercising, especially if you are exercising for a long time or in hot weather.
Some factors that affect your fluid intake are:
• The type and length of your workout
• The weather and the level of humidity
• How physically fit you are
• How much you sweat
• Whether you are wearing any clothing or equipment that causes you to sweat more
If you are exercising for a short time, you may not need to worry too much about your fluid intake – simply drink when you feel thirsty. If you are exercising for a long time or in hot weather, you may need to take more water with you on your workout. It is a good idea to replenish the fluids you lose when you finish your exercise.
In rare cases, some sportspeople may need to account for additional factors, such as the loss of salts in sweat, when determining their fluid intake.
What are some good ways to drink more water?
If you struggle to drink enough fluids, you do not need to come up with elaborate rituals or strategies to help you remember. Making a few small tweaks to your environment can be enough to significantly increase your fluid intake. Try keeping a water bottle at your desk or at your side while studying. You can try making drinking water a part of your daily rituals, such as having it with meals. You can also remind yourself to drink water when you are exercising or going out for the day. You can add flavor to your water with lemon, cucumber, or other fruits and herbs to make your water more enjoyable. If you find that your mind often forgets to remind you to drink water, you can set alarms or reminders on your phone or use special apps. You can prioritize water over other, unhealthier drinks and make sure to always have it available to you when you need it.
How can I be sure I am not dehydrated?
Your body will often tell you when it needs more fluids. If you feel excessively thirsty, you may be dehydrated, but you can also use other signs to help you assess your hydration status. You should not feel constantly thirsty throughout the day. Your urine should also generally be a pale-yellow color. If you have been exercising, you may notice that you have lost weight after your workout – most of it is likely to be water, so you should try to drink more fluids after you finish your workout.
Other symptoms of dehydration are dry mouth and lips, dizziness, fatigue, constipation, and less frequent trips to the bathroom.
How can I be sure I am not overhydrated?
As mentioned previously, overhydration is dangerous and can have unpleasant side-effects. Overhydration tends to occur when people drink way more fluid than their bodies need. It is relatively uncommon for people who do not engage in competitive or extreme sports to experience it.
Overhydration can also be caused by health issues unrelated to fluid intake, such as kidney or hormone problems. Some medications can also cause you to retain water.
In most cases, you can avoid overhydration by drinking fluids only when you are thirsty rather than following a strict water-drinking regime.
If you are not sure whether you are experiencing dehydration or overhydration, it is best to speak to a medical professional. Do not try to self-treat any potential condition.
Should I drink fluids if I have a fever?
If you have a fever, you should drink more fluids to ensure that you do not become dehydrated. Having a fever means your body temperature is hotter than normal, which causes you to sweat more than usual and, therefore, lose extra fluids.
Drinking water will prevent you from becoming dehydrated and will help your body recover.
In some cases, you may also need to replenish the salts your body loses when you sweat. If your fever is particularly severe or you are unsure what to do, speak to a medical professional.
Is there a difference between drinking water and other fluids?
As previously mentioned, drinking water is essential for your body to function, but you can consume other fluids as well. Many foods contain water, and you can get a considerable number of fluids from your regular diet. Juices and milk contain water and are nutritious, but they still contain other ingredients. Coffee and tea count towards your fluid intake, but they should be limited due to their caffeine content.
Most fluid-containing foods and drinks can be part of a healthy diet. The most effective balance depends on your personal needs and preferences.
Is there an easy way to remember how much water to drink?
There is no hard and fast rule about how much water you need to drink per day. The most important rule is to drink when you are thirsty and to increase your fluid intake when you exercise. The other rules are to always have water available to you and to drink it when you can.
Do not get obsessed about how much water you need to drink per day, and never try to drink more water than your body needs.
If you have a medical condition that affects your fluid intake or if a medical professional told you how much water you should drink per day, it is essential to follow their guidelines.
Water is vital to your body, but so is your health.
