By Jessica Migala, Oct 21, 2025

Clinical depression—the most severe form of depression—is complicated, and influenced by a variety of factors including individual brain chemistry, genetics, a history of trauma, and stress. Treatment of the condition, too, is complex, needing to address the biological, genetic, environmental, and psychosocial factors at play, which differ from person-to-person. “For depression treatment, I strongly believe in a multimodal approach, as evidenced by research,” says psychiatrist Alex Dimitriu, M.D., the founder of Menlo Park Psychiatry & Sleep Medicine in California. “In my practice, we help people with daily life habits likesleep, work, play, and exercise, we add therapy to improve understanding of the patient and their relationships, and we use medication when needed.”

6 Habits That Make Obstructive Sleep Apnea Worse

By Marygrace Taylor, Sep 25, 2025

CPAP therapy uses a mask to deliver continuous air pressure through your airway during sleep, which helps keep the area open and prevents breathing disruptions. But if the mask doesn’t fit correctly, it can end up leaking, which means you might not be reaping all of the benefits of treatment. “A poor CPAP mask fit essentially means most of the air is not getting where it needs to go: to your airway,” says Alex Dimitriu, MD, a board-certified sleep specialist and founder of Menlo Park Psychiatry & Sleep Medicine in Menlo Park, California.

5 Surprising Benefits Of Sleeping Naked—From Better Skin To Hotter Nights

By Shannon Dawson, Sep 19, 2025

Struggling to fall or stay asleep? Your body temperature plays a key role in regulating your sleep cycle, especially during REM sleep, the restorative stage when your brain and body recharge. According to a study by the National Institutes of Health, room temperature is one of the most crucial factors for quality sleep. Ideally, your bedroom should be between 60–67°F (15–19°C), according to the study, Healthline reported. Sleeping naked helps your body cool down more efficiently, which not only helps you drift off faster but also leads to deeper, more restful sleep, shared Dr. Alex Dimitriu during an interview with the New York Post, published Feb. 21. “When our bodies can cool off at night, we enter deeper stages of sleep (slow wave sleep) — which is why sleeping in a cooler environment is important.”

By Clarissa Brincat, Sep 16, 2025

“There is very little evidence supporting the use of lettuce water for sleep,” says Dimitriu. Lettuce contains extremely small amounts of two substances called lactucin and lactucopicrin, which are thought to have a mildly calming and sleep-inducing effect. “But there are very few studies supporting this, and none have been conducted in humans,” he cautions. 

Does Melatonin Cause Weight Gain? Exploring the Effects on Metabolism and Sleep Quality

By Jessica Migala, Sep 13, 2025

Overall, “melatonin supplements may lead to weight loss,” says Alex Dimitriu, MD, who is double-board certified in psychiatry and sleep medicine and the founder of Menlo Park Psychiatry & Sleep Medicine in Menlo Park, California. One big caveat: “Most of this research is from rat studies, and the doses of melatonin tested have been quite high,” Dr. Dimitriu says. What this tells us is that melatonin is not a supplement that should be used for weight loss. However, preliminary research suggests that you don’t necessarily need to worry that melatonin itself will cause weight gain, if this is a supplement you choose to take under your doctor’s recommendations.

What Are ‘Bipolar Eyes’?

By Elizabeth Millard, Sep 5, 2025

This effect, known colloquially as “bipolar eyes,” doesn’t happen to everyone and isn’t considered a hallmark symptom of the condition. However, it may be noticeable during a manic episode for some, says the psychiatrist Alex Dimitriu, MD, founder of Menlo Park Psychiatry and Sleep Medicine in California, and a medical reviewer at Everyday Health. “‘Bipolar eyes’ is a nonclinical term used to describe the look of someone in a manic episode, where the eyes convey excess energy or excitement,” he says. But, changes in eye appearance are just one potential part of a bigger picture when it comes to diagnosing and managing bipolar disorder.

The Egyptian Sleep Method Is Going Viral — But Does It Work?

By Kendra Cherry, Sep 3, 2025

“The Egyptian sleep method involves sleeping under a damp sheet, which cools off from evaporation,” explains Alex Dimitriu, MD, psychiatrist and founder of Menlo Park Psychiatry & Sleep Medicine. Because water absorbs heat as it evaporates, your body temperature drops as the water gradually evaporates. Some variations of this method suggest sleeping in minimal (or no) clothing. Another alternative is to wear a damp T-shirt to bed. For the best results, make sure that your bedroom is well-ventilated to avoid trapping excess humidity. He notes that sleeping under a wet cloth isn’t always the most desirable option, but it *can* be helpful in some cases. “If you are sleeping in a really hot environment, with no other options, it might be worth a go. Just don’t over-wet the sheet!” he says.

Why You Still Have Stress Dreams About School

By Chantelle Lee, Aug 29, 2025

Dr. Alex Dimitriu, a psychiatrist and sleep medicine doctor in Menlo Park, Calif., says that dreams of feeling unprepared can stem from stress in your day-to-day life. But dreaming specifically about feeling unprepared at school, he says, could be because those are such formative years in people’s lives. “For a lot of us, school is really the first time that we got that feeling of stressful non-preparation,” he says. “In a situation where your stress as an adult is triggered by work or some other scenario, those are very powerful memories of effectively the first experiences of being unprepared or late or missing something.”

Dr. Alex Dimitriu, who is double board-certified in psychiatry and sleep medicine and the founder of Menlo Park Psychiatry & Sleep Medicine, says that younger adults may need more sleep than older adults, but not by much.
