Drink container material safety

These notes combine advice from 4 reviewed passages across 3 workouts.

Overview

Coach’s advice

Drink container safety depends on the material of the container and on how the container is used. Metal containers are acceptable for drinking, and stainless steel in particular causes no problems. Tungsten is reportedly not toxic.

Coach’s advice

The cautions concern what goes into the container and how long the drink stays there. Fruit juice and acidic drinks should not be used with a tungsten drink container. If the container material leaks into a drink over time, it could poison the drinker. When water stays in a plastic bottle for more than a day, substances from the plastic can pass into it.

Container leaks

Coach’s advice

If the container material leaks into a drink over time, it could poison the drinker. The material of the container and the time the drink stays in it both play a role in this risk.

Acidic drinks

Coach’s advice

Fruit juice and acidic drinks should not be used with a tungsten drink container. The restriction is specific to tungsten items.

Plastic bottles

Coach’s advice

When water stays in a plastic bottle for more than a day, substances from the plastic can pass into it. The time the water spends in the bottle is what triggers the transfer.

Coach’s experience

In his own experience, the coach is bothered by the plastic bottle issue.

In his own use, the coach researched the safety of his drink container and is not fully certain that drinking from it is harmless.

In his own use, the coach avoids drinking hot things from his container, without being certain that this precaution is needed.
