Eating curd with sugar before exams or an important event: Curd is known to have a cooling effect on body and helps you calm down and relax. Plus the sugar gives you enough energy to complete the task at hand with gusto. So the next time your mom runs behind you with a spoonful of curd and sugar, just eat it without arguing.
Not stepping out during a solar eclipse: While it sounds like a superstition, it makes a lot of sense. During a solar eclipse, the Earth's gravitational waves are weak and allow UV rays from the sun to directly hit the earth. Exposure to UV rays can cause diseases like cancer and other skin diseases. That is why going out during an eclipse is prohibited, and not because of any superstition.
Sprinkling water around food plates while offering prasad: You think this makes no sense? Well, in older days, plates full of food would be kept on the floor. The food would attract insects and other creepy crawlies. Circling the plates with water prevented insects from reaching the food in the plates, preventing contamination.
Drinking water from copper vessels: It's an Indian tradition to store water in copper vessels overnight and drink that water in the morning. Copper has antibacterial and anti fungal and anti-inflammatory properties which help in healing wounds faster. Copper is also known to stimulate digestion and has cholesterol lowering properties. When water is stored in copper vessels, the copper slowly leaches and lends its properties to the water.
Eating with silver cutlery: The human body needs silver in trace quantities, and there's no way food can provide it. When food is served in silver cutlery, trace amounts of silver leaches into the food, which is just enough to meet your body's requirement.
Fasting: Fasting is usually associated with religion but did you know there's science behind it? Ayurveda recommends fasting at least once in a week to give your stomach and digestive system some rest. The digestive system works 24*7, and when you eat light for a day, it helps the digestive system recover from the fatigue.
Sitting on the floor and eating: Sitting on the floor while eating is known to improve digestion. The food is placed in front of you, and you constantly make the back and forth movement while eating. This action helps the stomach to secrete stomach acids, which also helps in digesting food more efficiently.
Using an Indian toilet to poop: Squatting is supposed to be a natural position which exerts the right amount of pressure on the muscles of your intestine, which starts pushing the waste towards the rectum. Squatting also relaxes the muscles between the anus and the rectum, which makes it easier for the bowels to evacuate. Sitting, on the other hand, does not relax these muscles and leads to incomplete excretion which further increases your risk of diseases like hemorrhoids.
Eating before sunset--Eating before sunset is a common practise among Jains and is an extremely healthy one. When you eat before sunset, there's a huge gap between your dinner and bedtime. This huge gap helps digestion, and the digestive system does not need to work overtime during night when the rest of your body is resting.
