Benefits of drinking a glass of water after waking up

Replenish fluids and electrolytes

While sleeping, the body does not take in food or water, and still loses water through breathing and sweat, leading to mild dehydration when waking up. This condition can cause fatigue, decreased energy, decreased concentration, and difficulty performing physical activities. Drinking water immediately after waking up helps rehydrate, restore energy and stay more alert.

Promote metabolism

Drinking water on an empty stomach creates a thermogenic effect, increasing metabolic rate, thanks to which the body burns calories more effectively during digestion. This morning habit can support energy expenditure throughout the day, contributing to weight maintenance and health.

Supports digestion and detoxification

Water helps move food and waste through the intestines, maintaining regular bowel movements and effective digestion. At the same time, water promotes good kidney function, eliminates toxins and maintains the body’s natural detoxification process.

Improve mood

After a night of sleep, mild brain dehydration can lead to fatigue, decreased concentration, poor alertness and forgetfulness. Drinking water early helps the brain function more effectively, lifts the spirit and is ready to start a new day.

Reduce fatigue and headaches

Dehydration is a common cause of fatigue and headaches. Drinking water immediately after waking up balances fluid intake, prevents these symptoms from appearing, and provides the energy needed to stay active all day.

Some beneficial ways to drink water in the morning:

• Drink 1-2 cups (250-500 ml) of water immediately after waking up to replace lost fluids.
• Do not drink sugary or caffeinated drinks (on an empty stomach) in the morning as they make you thirstier.
• Choose water that is room temperature or slightly warm. Warm water is easier to drink and aids digestion.
• People who exercise a lot should drink more water afterward to stay hydrated.

Drinking water immediately after waking up is good for most people. However, some people need to be cautious such as having kidney disease, heart failure or other heart diseases, stomach problems such as gastroesophageal reflux (should wait a while or take small sips). People with edema or fluid retention need to control their water intake, because drinking too much, too quickly can make the condition worse. You should consult your doctor or nutritionist to know the amount of water that is good for your health.
