Temperature regulation also plays a role in hormonal balance, particularly in the production of melatonin, the hormone responsible for sleep-wake cycles. Melatonin production typically increases in cooler environments, as indicated by research from the National Institutes of Health (NIH) . Sleeping in a cooler room—or without pajamas—can help facilitate this process naturally.

In addition, cooler environments may support lower nighttime cortisol levels. Cortisol, commonly known as the “stress hormone,” fluctuates throughout the day, but elevated levels at night can disrupt sleep. The Endocrine Society has linked nighttime temperature to cortisol regulation, showing that high temperatures may interfere with proper hormonal cycling .

While sleeping naked is not a cure-all for skin problems, ensuring airflow and reducing friction can support general skin hygiene and comfort—especially for those with sensitive or allergy-prone skin.

Allowing the body to rest without constriction may benefit those who experience issues related to poor circulation or nighttime discomfort, according to Harvard Health Publishing .

Again, this doesn’t imply that all clothing disrupts circulation, but rather that removing tight garments may alleviate some pressure or discomfort for certain individuals.
