Asian beauty secrets have astounded the world for years. And while genetics almost certainly play a huge role in their beauty, they abide by one simple habit that not only helps them to stay healthier, but also helps them maintain their beauty.

A major ritual for the people of Japan, drinking water first thing in the morning is considered to be a remedy for a number of major body disorders. While the U.S. and other Western nations suffer from obesity, diabetes, heart disease and more, the population of Japan doesn’t have a high rate for these various deadly issues.

And while it may be hard to admit, we surely could learn a thing or two from them!

Not only does drinking water first thing in the morning quench your thirst, but it also rejuvenates you in a number of ways.

If you don’t believe me, check out these 6 ways:

1. It fires up the metabolism.

When you drink water, it fires your metabolism up and increases its productivity by a whopping 24% for over 90 minutes!

2. It makes you more alert.

Rania Batayneh, MPH., a nutritionist and the author of ‘The One One One Diet,’ says that drinking a glass of water first thing in the morning is wonderful for increasing productivity. “One of the biggest indicators of lethargy or low energy is that you are dehydrated,” Batayneh says. “Because water aids in both body regulation and brain function, it is also closely related to balancing out our moods.”

3. It fuels your brain.

Our brain is composed of over 73% water. Maintaining hydration is essential for our brain staying at optimal levels and peak performance.

4. It fights sicknesses and makes your immune system stronger.

When we drink water on an empty stomach, it keeps viruses at bay by providing our immune system with the boost it needs to fight sickness and disease. A strong immune system is a key to fighting a number of viruses and sicknesses that can leave our system permanently damaged.

5. You eat less.

In a study, it was discovered that when we drink water before we eat, we can lose up to 4.5 pounds over a three-month period, without any other measures taken. Why? Because we eat less!

6. It flushes toxins.

“Your kidneys do an amazing job of cleansing and ridding your body of toxins as long as your intake of fluids is adequate”, according to Kenneth Ellner, an Atlanta-based dermatologist. Getting fluids into your body right after you wake up will help your body flush out toxins first thing in the morning.
