Bed of Nails: Risks and Safety Concerns - What You Need to Know

Lying on a bed of nails for an extended period of time can be dangerous. The nails can cause serious injuries to the skin and underlying tissues. In some cases, the nails can even puncture the skin and cause internal damage. Even if the nails do not puncture the skin, they can still cause pain, discomfort, and inflammation.

As such, there is no definitive answer to how long a person can lie on a bed of nails. The length of time that a person can safely lie on a bed of nails will vary depending on the individual's pain threshold and the type of nails used.
