How Many Calories Are Burned Drinking Hot Water?

There are many trending theories about ways to burn calories and combat weight gain, and one is by drinking hot water. Is this true? And if it is, how many calories are burned by doing it? We’ll examine if there is science supporting this and see if it is true.

Learning Hydration

Healthdirect provides vital information about hydration:

How Can I Stay Hydrated?

To stay hydrated, it’s important to drink enough water even before you feel thirsty. This is especially important if you are exercising or if it’s a hot day. Even if you’re not thirsty, try to drink at least 8 glasses of water throughout the day. Water contains 0 calories so drinking ice water or warm water will not increase your calorie intake or affect your self’s energy expenditure. You can tell if you are well hydrated by the colour of your urine. If it is pale yellow or straw-coloured, you are probably hydrated. If it’s darker, you need to drink more water.

You can see the colour of your urine should be on this urine colour chart — but remember that taking some medicines or vitamin supplements can change the colour of your urine for a few hours.

Stay hydrated: sip water before thirst kicks in. Crucial during exercise or hot weather. Aim for 8 glasses daily.

You can increase water intake by:

  • always carry a water bottle with you
  • keeping chilled water in the fridge on hot days
  • flavouring water with lemon, strawberries, or mint to add flavour
  • always have a glass of ice water or warm liqui on the table when you’re eating

What is the Benefit of Drinking Hot Water?

The following listed below are the health benefits of warm water as stated in Water Filters Australia:

Warm water has health perks, per Water Filters Australia:

  • Improves & Aids Digestion
    A glass of warm water first thing in the morning kick-starts the digestive system.
  • Improves Blood Circulation
    It’s believed that hot or warm water aids blood flow improving circulation. As the blood flow increases, this, in turn, helps to rid the body of toxins.
  • Helps To Reduce Toxins
    Warm water helps to flush out toxins in the body. It’s great for flushing the liver tissues so the toxins can be removed via the skin and bowels.  This in turn helps the kidneys to filter properly and contributes to overall wellness.
  • Relieves Constipation
    This condition can often be brought on by dehydration. It’s good to be aware of the common dehydration warning signs. A glass of warm filtered water in the morning will help to improve bowel functions. The warm filtered water will help break down foods so they can pass easily through the intestine.
  • Helps With Menstrual Cramps
    If you suffer from uncomfortable cramping at a certain time of the month then a glass of warm filtered water can help. It will help the muscles relax and the cramps ease.
  • Helps with a Cold & Sore throat
    Drink a glass of warm filtered water for colds and sore throats. It acts as a natural expectorant by helping to get rid of phlegm in the respiratory tract.
  • Decreases Stress
    Drinking a glass of hot/warm water, helps your muscles to relax which the body needs.
  • Helps Maintain a Healthy Weight
    Warm water increases your body temperature and metabolic rate, making your body burn extra calories.

Water Consumption Can Contribute to Calorie Burn

According to Healthline, drinking 0.5 litres (17 oz) of water may increase the number of calories burned for at least an hour. Some studies show that this can lead to modest weight loss.

Drinking 0.5L (17oz) water may boost calorie burn for an hour, aiding weight loss.

The bottom line is – can drinking hot water burn calories?

The temperature of the water does not matter when it comes to burning calories and weight loss – you can drink plain water at all temperatures – drinking cold water, warm, or room temperature water, and as long as you drink 2 litres or more, your weight loss journey will be smooth when you couple it with a healthy diet and regular physical activity. Medical advice from a nutritionist or dietitian and guidance from a fitness personal trainer may help.

So, there you have it. Drinking hot water or even ice-cold water can slightly increase the number of calories you burn each day. If you are looking to lose weight, focus on making healthy lifestyle choices such as eating food with fewer calories (like apples) and exercising regularly as these are the most effective ways to achieve your weight loss goals.
