This study is looking at ways to improve sleep and natural body rhythms (circadian rhythm) in children aged 3 to 6 years old who are in the intensive care unit (PICU). Researchers are testing two interventions: providing daytime light exposure using a special light source for 2-3 hours in the morning, and restricting all nutrition (food given through tubes or IVs) to daytime hours. The main goal is to see if it's possible to measure sleep and circadian rhythms in these children and if these interventions can be practically used in the PICU. To join, your child must be 3-6 years old, expected to stay in the PICU for more than 24-48 hours, and you, as the parent, must be English-speaking and at their bedside. The study is currently unclear on its recruitment status.

Study design

This is an interventional pilot study planning to enroll 30 participants. It is testing specific interventions rather than comparing them to a placebo.

What's involved

Participants will receive daytime light exposure and have their nutrition restricted to daytime hours. Sleep and circadian rhythm will be monitored from PICU Day 1 through Day 4.

Compensation

Not stated in the trial record.

Follow-up

Participants will be monitored for their sleep and circadian rhythm from PICU Day 1 through Day 4.
