“We know that light, whether artificial or natural, can have a suppressant effect on melatonin, so it is plausible that moonlight could have a natural wake promoting effect,” says Dr. Alex Dimitriu, a psychiatrist and sleep medicine specialist, and founder of Menlo Park Psychiatry and Sleep Medicine.

“Work, especially cognitively demanding tasks, can keep your brain in a state of alertness,” said Alex Dimitriu, MD, a dual board-certified in psychiatry and sleep medicine physician. “Your brain cannot go from 100 mph to zero quickly. Stepping away from work-related stress well before lights out helps signal to your brain that it’s time to wind down.” According to the 10-3-2-1 method, two hours is the sweet spot.

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.

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.”

“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.

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.

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 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.

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.”

Doctors and researchers generally recommend that adults sleep seven to eight hours at night. 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. Recommended increases are closer to a few minutes than a few hours and “will likely fall into the seven to eight hour range,” he adds. While not everyone needs a full eight hours of sleep, Dimitriu encourages people to aim for the higher end of the range in order to confidently lock in their Zs.

Alex Dimitriu, M.D., a psychiatrist and sleep medicine doctor who is founder of Menlo Park Psychiatry & Sleep Medicine in California, was not involved in the research but commented on the findings. “The more general message here is that there is a benefit to measuring sleep objectively, and looking at more than just the total sleep time,” he told Fox News Digital.

While taking any medication, it’s important to use caution when drinking alcohol, says Alex Dimitriu, M.D., a double board-certified specialist in psychiatry and sleep medicine and founder of Menlo Park Psychiatry & Sleep Medicine. Dr. Dimitriu specifically recommends limiting alcohol intake when taking methylphenidate. “Alcohol is a sedative, while Ritalin is a stimulant. When taken together, they can work in opposing directions on the cardiovascular system and the nervous system,” notes Dr. Dimitriu. “Ritalin may mask intoxication from alcohol and result in increased consumption, which can be dangerous,” he explains.
