Our bodies are 60-70% water, and therefore we need to consider water as an essential nutrient. Becoming dehydrated can cause all sorts of problems. However, it’s also possible to drink too much water. So, how much water should we drink, and what types of water filters should we use?
In the days when it was extremely difficult for me to get moving in the mornings, I got into the habit of drinking 3 glasses of water first thing. This was essential for me at that time, and I’ve stayed in the habit of drinking lots of water. However, when researching for this article, I discovered that I’ve been drinking too much water, and it’s been contributing to my ongoing sleep problems.
Water has a number of important functions in the body.
- It’s essential for good blood flow. If you get dehydrated, your blood gets thicker and your blood pressure increases. The pressure on your heart increases and your blood becomes less efficient at delivering vital nutrients.
- Water helps digestion because it helps to break food down in the digestive system. This helps to avoid constipation.
- Water helps respiration because it is a lubricant in the lungs.
- Water helps with mobility and joint lubrication. Muscles are about 80% water.
So, how much water should we drink? We are normally advised to drink 8 glasses a day. However, this may be too much for some people and not enough for others.
There are early signs you can look out for to see if you’re not drinking enough water and you’re becoming dehydrated. These include headaches, lethargy, dry skin, muscle weakness, dizziness, and lack of focus.
When considering whether you are drinking the right amount of water, you need to bear the following in mind:
- How much you sweat. If you sweat a lot, you need more water.
- Your size. The bigger you are, the more water you need.
- How much you exercise. If you exercise a lot, you need more water.
- Your diet. Processed foods are largely dehydrated. However, fresh food such as fruit, vegetables, and meat will contribute a lot to your overall water intake. (This was my mistake. When deciding how much water to drink, I didn’t take into account how much water I was getting from my diet.)
- Your thirst mechanism. You need to listen carefully to your body because it will tell you when you need more water.
- How many times you’re urinating a day. 6-8 times is usually enough. 8-12 times is probably too much. However, when considering your urination rate, you also need to consider whether you are drinking diuretics such as caffeine.
It’s important to consider how much water you’re drinking, but it’s also important to make sure the water you’re drinking is clean.
In the video Water Filtration – which type of filter is right for you? (see below), Dr Peter Osborne looks at the various different types of filters, especially in regards to their ability to pull fluoride from the water. In summary, he recommends the following:
- A whole house water filtration system using GAC (Granular Activated Carbon) and KDF (Kinetic Degradation Filters). A whole house system is necessary because the chemicals in tap water can be absorbed through the skin when showering. This kind of system will purify the water to a certain extent, but it won’t pull out fluoride.
- A RO (Reverse Osmosis) filter in the kitchen for drinking and cooking. This will take out fluoride. However, it also takes minerals out of the water and therefore electrolytes will have to be added back in before drinking.
Bottled water is not a good alternative. When tested, a lot of bottled water turns out to be no better than tap water. Furthermore, the plastic from the bottles leaches into the water (even if the bottle is labelled BPA free) and can reduce immune function and act as a chemical oestrogen. (Water bottled in glass may be OK.)
Drinking the right amount of the right kind of water can have a huge effect on our health. And it’s such a simple and basic thing to do. So, the next time you have a headache, tryi just drinking a glass of water before you reach for the pain-killers. You may simply be dehydrated.
How much water should I drink? Is the "8 glasses" rule valid?
