It is advisable to avoid storing water in plastics bottles because it can get contaminated with the chemicals used in making them, said Dr Ashit Bhagwati.
Many of us wake up feeling thirsty and instinctively grab the bottle kept on the bedside table to drink water. But have you ever wondered whether you should be drinking water that has been left to sit overnight, or in simple terms, stale water?
The human body is made up of 70 per cent water. It is essential to drink water to maintain the body’s temperature, detox it through sweat, urination and bowel movements, and lubricate the joints.
If water is left in the open without a cover, it mixes with carbon dioxide. While there is no harmful effect of this, it slightly reduces the pH level of water. The effect of reaction is minimal, said Dr Gaurav Jain, consultant, internal medicine, Dharamshila Narayana Superspeciality Hospital, Delhi. However, the expert added that while is safe for a healthy person to drink water that’s been sitting overnight, “if this water is consumed by an already ill or unhealthy person, it may make them prone to catching another infection through contamination since their immunity is low. But, there is no harm in drinking stale water if it is stored properly,” he told indianexpress.com.
Dr Ashit Bhagwati, honorary consultant, internal medicine and honorary academic director, ICU at Bhatia Hospital Mumbai said that contamination can occur if water is left uncovered. “Our environment is filled with tiny dust particles and other pollutants which settle down over a period of time. So leaving a glass of water uncovered all night will lead to contamination from dust and other particles,” said Dr Bhagwati.
Alternatively, the container used to store water may become smelly over a period of time due to usage, making it essential to clean it after every use. Not doing so also makes it a collection ground for bacteria and other viruses that can pass through the bottle brim to the water, explained Preety Tyagi, Lead Health Coach, Nutritionist, and founder of MY22BMI.
Experts suggest it is also best to avoid consuming water kept in closed spaces like cars. “Water kept for long in plastic bottles or closed containers in a car is not safe as it heats up in sunlight and allows bacteria to breed,” said Dr Jain.
So, what is the best way store water?
Tyagi mentioned that it is better to avoid water that has been left over the countertop or on the bedside table overnight. “The best practice is to walk up to the source of water such as the water filter and grab a fresh glass, fill it up with fresh water and consume,” she said.
It is advisable to avoid storing water in plastics bottles because it can get contaminated with the chemicals used in making them, said Dr Bhagwati. “In early times people used earthen pots and copper to store water which are comparatively safer,” she added.
According to ayurvedic practitioner Dr Dixa Bhavsar, the quality of water stored in a copper vessel as per Ayurveda are:
Ushna – hot in nature
Rasa (taste) – sweet and slightly pungent
Katu vipaka – undergoes pungent taste conversion after digestion
In an Instagram post, she mentioned that Ayurveda recommended to store water in copper vessels as it has the ability to kill bacteria, if any.
