Some days, it’s hard enough to find time to take a bathroom break… let alone stop for a quick drink of water. And that icreases your risk of dehydration, which can be bad for your heart.
We all know that we should be drinking more water on a daily basis and that’s especially true during the summer months – when you start sweating as soon as you walk out of the door and it’s even more critical to stay hydrated.
It’s not just that our bodies are made up of about 60 per cent water, which is the primary building block of cells.
Water also regulates your body temperature, insulates your brain and other organs, absorbs shock, metabolises food, and carries waste out of your body.
According to the latest research, not getting enough water makes your heart’s job even harder and dramatically slows your reaction times.
The BBC reported that water deprivation during exercise can make you feel more winded and can send your heart rate through the roof, compared to a workout under the same exact conditions while drinking water.
There’s a lot of water flowing through your blood – but a lack of water intake, coupled with the loss of water through sweat, makes your blood thicker. And anyone who’s ever been put on a blood thinner knows that thick blood makes the heart work extra hard just to keep it pumping.
What’s more, dehydration affects more than your body. It can also affect your mind!
In the study, researchers found that a person’s reaction performance can be cut by nearly a third when dehydrated, and their hand-eye coordination can be significantly impaired as well.
A related study on British athletes reported similar outcomes, with dehydration causing a 20 per cent drop in accuracy and a two per cent reduction in overall speed.
Now, when you are exercising you have to at least replace the fluids you’re losing when you sweat – and this is even more important when you exercise in hot weather. In this latest study, the subject lost the equivalent of FOUR GLASSES during his workout.
Remember that if you’re feeling thirsty, it’s already too late. You’ve lost 2 to 3 per cent of your body’s water, but the physical and mental impairment starts when you’ve only lost about 1 per cent of your body’s water.
And if you’ve already lost even just 1 per cent water, you’re dehydrated.
As I shared with you recently, dehydration has also been linked to a higher BMI – but drinking water can help you shed some of that extra weight.
Don’t forget that you get much of your water from what you eat, so you can also bulk up on high water content foods like watermelon (which is 92 per cent water), cucumbers, and celery in addition to those big glasses of water.
Wishing you the best of health,
