the Risks of Alcohol Disinfectants and Spa Water Ingestion

Disinfectant alcohol

Hello, I would like to ask a few questions:
1.
When entering a public place, the staff sprayed my hands with disinfectant alcohol, and then I touched food with my hands.
If this disinfectant alcohol is ingested, could it cause any problems in the body?
2.
Two days ago, while soaking in a hot spring, I accidentally ingested a little hot spring water.
Could this cause any problems?
3.
If a liquid that is not meant for drinking enters the body, will it always be excreted? If it has caused harm to the body, what symptoms might occur?

1.
Upon entering a public place, the staff first sprayed my hands with disinfectant alcohol, and then I touched food with my hands.
If this disinfectant alcohol were to be ingested, would it cause any problems? ANSWER: If it is pure alcohol, it should have already evaporated.
2.
Two days ago, while soaking in a hot spring, I accidentally ingested a little hot spring water.
Will this cause any problems? ANSWER: If you are not experiencing any discomfort now, then it should be fine.
3.
If a liquid that should not be ingested enters the body, will it always be excreted? ANSWER: Water will be excreted, but harmful solutes may cause damage.
If harm has already occurred to the body, what symptoms might arise? ANSWER: That would depend on what you ingested.

When it comes to the use of alcohol disinfectants and the ingestion of spa water, there are several important considerations regarding health and safety. Let's address your questions one by one.

1. Ingestion of Alcohol Disinfectant: If a person has their hands sprayed with a 75% alcohol disinfectant and then eats without allowing the alcohol to evaporate, there is a risk of ingesting a small amount of alcohol. While the primary concern with alcohol ingestion is alcohol poisoning, the amount typically transferred from hands to mouth in this scenario is likely to be minimal. Ingesting a small amount of alcohol (especially in the context of hand sanitizers) is generally not harmful for most adults, but it can pose a risk for children or individuals with certain health conditions. Symptoms of alcohol ingestion can include dizziness, nausea, vomiting, and in severe cases, respiratory depression or unconsciousness. If you suspect significant ingestion, it is advisable to seek medical attention.

2. Ingestion of Spa Water: Drinking a small amount of spa water is generally not harmful for most people, but it depends on the water's quality. Spa waters can contain various minerals and microorganisms, and if the water is not properly treated, it could potentially lead to gastrointestinal issues. Symptoms may include nausea, diarrhea, or abdominal discomfort. If you experience any of these symptoms after ingesting spa water, it is wise to consult a healthcare provider. In some cases, spa water may also contain chemicals used for treatment, which could pose additional risks if ingested.

3. Excretion of Harmful Liquids: The human body has mechanisms to eliminate many substances, including some that are harmful. However, not all substances are easily excreted, and the body's ability to do so can depend on various factors, including the substance's chemical nature, the amount ingested, and individual health conditions. For example, alcohol is metabolized primarily by the liver and can lead to toxicity if consumed in large amounts. Symptoms of toxicity can include confusion, difficulty breathing, and loss of consciousness. Other harmful substances may cause different symptoms based on their nature. If a harmful substance is ingested, it is crucial to seek medical attention immediately, as some substances may require specific treatments to mitigate their effects.

In summary, while small amounts of alcohol disinfectant and spa water ingestion may not lead to significant health issues for most adults, caution should always be exercised. It is essential to allow alcohol disinfectants to dry completely before eating and to be mindful of the quality of water consumed, especially from public or recreational sources. If you experience any adverse symptoms after exposure to these substances, do not hesitate to seek medical advice. Always prioritize safety and hygiene in public spaces to minimize health risks.
