Sleep as Medicine: A Psychiatrist's Guide to Deep Rest and Healing

"In psychiatry and medicine in general, sleep should be considered a vital sign," declares Dr. Alex Dimitriu, a psychiatrist and sleep medicine specialist. This bold statement sets the stage for a journey into the depths of sleep's profound impact on our mental and physical health.

Why Does Sleep Matter So Much?

Sleep isn't just about resting our weary bodies; it's a symphony of cycles, each playing a crucial role in maintaining our well-being. "Sleep has a cyclical structure that repeats about every 90 minutes during the night," explains Dr.Dimitriu. These cycles comprise light sleep, deep sleep, and REM sleep, with deep sleep being particularly vital,especially in the first half of the night.

What Happens During Deep Sleep?

Deep sleep is the brain's maintenance crew, diligently clearing out the debris accumulated during the day's cognitive activities. "During deep sleep, the brain does massive maintenance work, cleaning out the by-products of a day's worth of thinking," says Dr. Dimitriu. Among these by-products are proteins linked to Alzheimer's disease, making deep sleep crucial for cognitive health.

Furthermore, deep sleep is instrumental in memory formation and processing. It's like a librarian organizing information,moving memories from temporary shelves to permanent ones and creating space for new knowledge. This is why a good night's sleep is so essential before exams!

Why is REM Sleep Important?

As the night progresses, we transition into REM sleep, the realm of dreams. "Think of REM sleep as the ultimate virtual reality experience," suggests Dr. Dimitriu. While our bodies remain still, our brains are abuzz, processing emotions, consolidating memories, and even fostering creativity.

REM sleep is like a therapist, helping us make sense of our emotional experiences and simulate future scenarios. It's also a playground for creativity, where the brain tests out new connections, leading to those sometimes bizarre but often insightful dreams.

How Does Sleep Affect Our Mental Health?

Lack of sleep can wreak havoc on our mental state. It impairs impulse control, making us more prone to unhealthy choices and emotional outbursts. "Moods are more intense and tempers shorter after a night of poor sleep," warns Dr. Dimitriu. The prefrontal cortex, responsible for impulse control, is the first to suffer when we're sleep-deprived.

Over time, the consequences of sleep deprivation extend beyond mood swings. It increases the risk of various health problems, including obesity, diabetes, hypertension, and even heart attacks.

How Has Modern Life Disrupted Our Sleep?

Modern life, with its artificial lights and electronic devices, has made sleep an afterthought. The constant stimulation from our screens keeps our brains engaged, making it difficult to wind down and prepare for rest. As Dr. Dimitriu puts it,"Electric lights and electronic devices have made sleep a last priority."

How Can We Reclaim Our Sleep?

Dr. Dimitriu offers some valuable tips for improving sleep:

• Aim for seven to eight hours of sleep per night.

• Establish a consistent sleep schedule.

• Create a relaxing bedtime routine.

• Embrace silence and minimize distractions before bed.

The Power of Silence

In our fast-paced world, silence has become a rare commodity. However, Dr. Dimitriu emphasizes its importance for good sleep. "If you want to sleep better at night, give yourself a chance to think earlier in the day," he advises. Engage in activities that allow your mind to wander and process information without the constant bombardment of digital stimuli.
