7 reasons to start drinking water on an empty stomach:

Digestive system: The food pipe, after having digested a variety of foods the previous day, would still be left with remnants. Starting the day with a glass of warm water acts as a good flush, which removes all these remnants. The warm or hot water also helps in removing greasiness, which is very helpful in people who eat a lot of junk food.

Helps in Weight loss: Drinking warm water on an empty stomach is perfect for those who are trying to lose weight as warm water raises body temperature and the metabolism. This, eventually, helps in burning more fat and boosting the weight loss efforts through diet and exercise changes. Ideally, you should add some drops of lemon in it. 

Strengthens Immune system: When a glass of hot water along with some lime is consumed early in the morning, it gives the required dose of vitamin C and potassium to the body, which strengthens your immunity system. Also, as the stomach is empty, the absorption is faster. 

May prevent headaches or migraines. People often ignore this well-known fact. One of the primary reasons for a migraine or a headache is dehydration. Beginning your day with a glass of water can offset the chances of developing one. Continue drinking water through the day to prevent the onset of one.

Maintains body’s pH balance: The body’s pH turns alkaline as the ascorbic acid and the citric acid is easily digested and removed from the system. Drinking warm water helps in maintaining the required pH in the body.Keeps you positive throughout the day: A nice juicy lime smells great, and this can be one of the best mood enhancers to begin your day with.

Skin and hair: For anybody with good skin, the key success factor is hydration, and a glass of warm water in the morning works like a cherry on the cake. When our body accumulates toxins, it becomes prone to illness and aging. A glass of hot water in the morning stimulates detoxification and helps in repairing skin cells and elasticity.

So, start your day with a glass of warm water and feel the difference.
