Short answer: it depends on where you live. Tap water safety varies a lot by country, city, and even neighborhood.

In general

• Many places do not have reliably safe tap water for drinking without treatment.

• Even where water is treated, old pipes, storage tanks, or intermittent supply can contaminate it.

• Clear water ≠ safe water.

Short answer: No — your microwave is not giving you cancer.

Here’s why 👇

🔬 How microwaves work

• Microwaves use non-ionizing radiation

• This type of radiation cannot damage DNA

• Cancer is linked to ionizing radiation (like X-rays, gamma rays, nuclear radiation)

So the radiation from a microwave does not cause cancer.

Colds

You’re usually contagious:

• 1–2 days before symptoms start

• While you have symptoms

• Most contagious in the first 2–3 days

• Can remain contagious for up to 7 days

• Children may spread it longer (10+ days)
