Dr. Neena Chandrasekaran instructs how to take a scientific nap, from 12am to 14h, at 20 minutes.
According to Dr. Neena Chandrasekaran, respiratory expert and emergency resuscitation, nap has many benefits but needs to follow the proper method.
The most ideal time for napping is from 12h to 14h, because this is the time when the biological rhythm of the body decreases. Napping during this time will not affect night sleep.
Chandrasekaran recommends avoiding napping after 15 hours to maintain a stable night sleep. However, this rule may be different for people who work at night shifts or have weekly sleep cycle disorders.
Ideally taking a nap is 20 minutes. This time helps the body to rest fully, alert and not tired. Sleeping more than 20 minutes can cause drowsiness and discomfort.

In a previous video, Dr. Chandrasekaran also mentioned the benefits of napping on the brain.
A study on people from 49 to 67 years old shows the relationship between regular napping and greater brain volume. This helps reduce the risk of dementia, cognitive impairment and brain function improvement when old.
