In our daily lives, we always turn on the faucet to wash our hands every morning, but many people overlook an important thing, which is the overnight water in the faucet. It is best not to use the overnight water in the faucet directly for washing, even if it is boiled and used for drinking! Normally, you should turn on the faucet in the morning and let it run for about 1 minute before using it. The discharged water can be used to flush the bathroom, water the flowers, wash the floor, etc. So why can't the overnight water from the faucet be used directly?
1. The overnight water from the faucet may contain Legionella bacteria that can cause pneumonia
Legionella pneumonia is the most severe type of atypical pneumonia, with a mortality rate of up to 45%. According to research, Legionella bacteria can be isolated from tap water pipes in lakes, hotels, hospitals, and homes. Therefore, it is highly likely that Legionella bacteria exist in overnight water from faucets, and people who consume overnight water directly are prone to contracting Legionella pneumonia.
2. Long term consumption of overnight water in tap water pipes may lead to lead poisoning
The water in the tap water pipe will undergo chemical reactions with the metal in the faucet or water pipe, forming metal contaminated water. Moreover, the microorganisms in the tap water will also produce harmful substances to the human body after a night of reproduction. If the faucet used is of poor quality, it is more likely to cause excessive lead content in the water.
As is well known, excessive lead entering the human body can damage the brain's neural tissue, cause insufficient oxygen supply, cause brain tissue damage, and lead to symptoms such as anemia, headache, and fatigue. Moreover, if it enters the body of children or pregnant women, it can cause irreparable damage to underage children, including developmental delays, deformities, premature birth, and other phenomena.
So, when we wake up every day to use the faucet, it's best to turn on the faucet and let it run for 1 minute to clean the overnight water, and to use buckets to hold the overnight water to avoid wasting resources.
