Insights from a Neurologist in Miami

Sleep is one of the most important pillars of brain health, yet millions of people struggle with sleep disorders that affect their daily lives. Miami neurologist Dr. Sergio Jaramillo explains that sleep problems are more common than many people realize and can have significant impacts on cognitive performance, mood, and long-term neurological health. Drawing on insights shared during a sleep health discussion with specialists from Baptist Health, Dr. Jaramillo highlights how understanding sleep patterns, identifying sleep disorders, and improving sleep hygiene can dramatically improve overall well-being.

One of the first things Dr. Jaramillo emphasizes is that recommended sleep duration varies depending on age. According to guidelines from the National Sleep Foundation, newborns require the most sleep, typically 14–17 hours per day, while school-aged children benefit from 9–11 hours of sleep each night. Teenagers generally require 8–10 hours, and adults between the ages of 18 and 65 typically need 7–9 hours of sleep per night. However, Dr. Jaramillo notes that sleep requirements can vary from person to person, meaning some individuals may function best slightly outside those ranges.

While occasional poor sleep is common, persistent sleep problems may indicate a sleep disorder. Specialists often see patients experiencing symptoms such as difficulty falling asleep, waking frequently during the night, excessive daytime fatigue, or loud snoring. Conditions like insomnia and sleep apnea are among the most common sleep disorders. Sleep apnea occurs when the airway becomes partially or completely blocked during sleep, reducing oxygen levels and repeatedly waking the brain to restart breathing. Over time, untreated sleep apnea may increase the risk of high blood pressure, heart disease, stroke, and other serious health problems.

Dr. Jaramillo also explains that it is important to distinguish between a sleep disorder and a sleep disturbance. A sleep disorder is a medical condition affecting the body’s ability to sleep normally, such as insomnia or sleep apnea. A sleep disturbance, however, may be caused by external factors, such as environmental noise, a partner moving in bed, or caring for a child during the night. Although disturbances may disrupt sleep, they do not necessarily indicate an underlying medical condition.

Risk factors for sleep disorders can vary depending on the condition. Some sleep disorders have genetic or hereditary components, meaning individuals with a family history may be more likely to develop similar issues. Physical factors can also play a role. For example, people who are overweight may have a higher risk of sleep apnea, although Dr. Jaramillo notes that even individuals with a healthy weight can develop the condition due to anatomical differences in the airway. Because sleep disorders can present differently in each person, proper medical evaluation is essential.

One of the most powerful ways to improve sleep naturally is through good sleep hygiene. Sleep hygiene refers to the daily behaviors and environmental factors that support healthy sleep. Specialists recommend creating a sleep-friendly environment that is cool, dark, quiet, and comfortable. Exposure to bright light, particularly from phones or tablets, can interfere with melatonin production and disrupt the body’s internal clock. Maintaining a consistent sleep schedule and avoiding stimulating activities close to bedtime can help reinforce the brain’s natural sleep signals.

Dr. Jaramillo also highlights how mixed signals to the brain can interfere with sleep. Activities such as using electronic devices in bed, consuming caffeine too late in the day, or engaging in stimulating behaviors close to bedtime can confuse the brain’s sleep-wake system. While some individuals may tolerate these habits better than others, repeated exposure can eventually lead to chronic sleep problems. Practicing consistent habits and limiting stimulants in the evening can significantly improve sleep quality.

Another common question involves sleep aids and medications. Over-the-counter options like melatonin or nighttime medications are widely used, but Dr. Jaramillo advises caution. Occasional use may be acceptable for short-term sleep difficulties, but relying on sleep aids regularly can reduce the body’s ability to fall asleep naturally. Instead, specialists increasingly recommend approaches that address the underlying causes of sleep issues, including behavioral strategies that help restore natural sleep patterns.

Sleep also plays a crucial role in children’s development. Dr. Jaramillo explains that sleep deprivation in children may appear differently than in adults. Rather than appearing tired, children who lack adequate sleep may become hyperactive, struggle academically, or develop behavioral challenges. Because sleep habits formed during childhood often continue into adulthood, establishing consistent sleep routines early in life can have long-lasting benefits.

There is also growing evidence linking sleep with long-term neurological health. Dr. Jaramillo notes that researchers believe there may be a bidirectional relationship between sleep disorders and neurodegenerative conditions such as Alzheimer’s disease. Disruptions in circadian rhythm may serve as early indicators of neurological changes, while individuals with Alzheimer’s often experience fragmented sleep and excessive daytime fatigue. Maintaining healthy sleep patterns may therefore play an important role in protecting brain health over time.

For people experiencing ongoing sleep problems, Dr. Jaramillo encourages seeking medical guidance rather than ignoring the symptoms. Persistent insomnia, loud snoring, excessive daytime sleepiness, or unusual nighttime behaviors may indicate an underlying sleep disorder that requires professional evaluation. Through proper diagnosis and personalized treatment strategies, many sleep conditions can be effectively managed.

Miami neurologist Dr. Sergio Jaramillo continues to educate patients about the critical role sleep plays in brain function and overall health. For individuals struggling with sleep disorders, improving sleep hygiene, maintaining consistent routines, and consulting a specialist when symptoms persist can help restore healthier sleep patterns and improve quality of life.
