Why undergoing this examination?

Sleep is a necessary activity for the restoration of the body and mind functions, promoting physical regeneration and memory consolidation, as well as strengthening the immune system. 

Melatonin, a hormone produced mainly in the pineal gland, plays a crucial role in sleep regulation. It is released in response to darkness and acts as a sleep inducer, contributing to the maintenance of the circadian rhythm. Associated with melatonin dysfunction, delayed sleep phase syndrome is a growing condition that results in obstacles to the onset of nighttime sleep, as well as compromising morning vigilance and daytime performance. 

What is this exam?

The Sleep Alteration – Melatonin Biorhythm Test involves determining melatonin levels in saliva at different times during the night (10 PM, 2 AM, 4 AM, 8 AM). This allows for the assessment of the patient’s melatonin biorhythm profile at key peak times, relating them to the wake/sleep biorhythm and detecting any deviations from the normal pattern, both in terms of timing and intensity. 

For whom is it indicated?

• Individuals with sleep disorders. 
• People with rotational changes in work hours experiencing sleep disturbances. 
• Individuals with long-term stress, depression, or professional burnout syndrome. 
• Those who frequently travel (jet lag). 
• People who want to proactively manage their health, especially after the age of 40.
