The Role of Cortisol in Sleep Regulation

What is Cortisol?

 

Cortisol is a hormone produced by the adrenal gland that helps the body respond to stress. It plays a vital role in regulating blood sugar levels, aiding in the metabolism of fat, protein, and carbohydrates, and assisting in the reduction of inflammation.

 

How Does Cortisol Affect Sleep?

 

Research has shown that higher pre-sleep cortisol levels are associated with shorter total sleep time and lower sleep efficiency. Individuals with shorter average sleep times or lower average sleep efficiency have flatter diurnal cortisol slopes, which is indicative of a dysregulated stress-response system.

 

The Impact of Cortisol on Sleep Quality

 

  • Sleep Duration: Higher pre-sleep cortisol levels predict shorter subsequent total sleep time.
  • Sleep Efficiency: Higher pre-sleep cortisol levels are linked to lower sleep efficiency.
  • Sleep Onset Latency: Higher pre-sleep cortisol levels are associated with longer sleep onset latency.

Managing Cortisol for Better Sleep

 

  1. Establish a Consistent Sleep Schedule: Regular sleep patterns help regulate cortisol levels.
  2. Practice Relaxation Techniques: Activities like meditation and deep breathing can reduce cortisol levels before sleep.
  3. Limit Exposure to Screens Before Bed: The blue light from screens can interfere with cortisol regulation.
  4. Exercise Regularly: Physical activity can help manage stress and reduce cortisol levels, but avoid vigorous exercise close to bedtime.
