ZZZ's (Sleep and Aging for Seniors)

You might have heard people say that we need less sleep as we get older. But the truth is — adults over 60 still need 7 to 9 hours a night. What does change, though, is how we sleep. As we age, we spend less time in deep sleep — that’s the stage where our body really gets to work repairing and refreshing. During sleep, our bodies repair muscles, our immune systems recharge, and our brains process memories. Poor sleep can make it harder to concentrate, increase the risk of falls, and even impact heart health. Plus, things like arthritis, medications, or even a snoring spouse (hey I’m just saying!) can disrupt our rest. And let’s not forget — our internal clocks shift. That’s why some of us turn into early birds — up at 5 AM and ready to tackle the day before the rooster crows. Sleep is not a uniform state; it consists of several cycles that occur throughout the night. Each cycle can be divided into two main categories: Non-Rapid Eye Movement (NREM) and Rapid Eye Movement (REM) sleep. NREM sleep can be further broken down into three stages: 1. Stage 1: The lightest sleep, where you drift in and out of consciousness. This stage is brief, typically lasting only a few minutes. 2. Stage 2: A deeper sleep where your heart rate slows and body temperature drops. This stage lasts longer and prepares your body for deeper sleep. 3. Stage 3: Often referred to as deep sleep, this stage is crucial for restorative processes. It’s during this phase that your body repairs tissues, builds bone and muscle, and strengthens the immune system. REM sleep, on the other hand, is when most dreaming occurs. This stage is essential for cognitive functions such as memory consolidation, learning, and emotional regulation. Together, these stages create a complex tapestry that rejuvenates both body and mind. During sleep, various processes happen that are essential for overall well-being. • Immune Function: Sleep enhances your immune system's ability to fight off illness. Studies have shown that lack of sleep can lead to a decrease in immune response, making you more susceptible to infections. • Metabolism and Weight Management: Adequate sleep helps regulate hormones related to appetite. Sleep deprivation can disrupt the balance of ghrelin (the hunger hormone) and leptin (the satiety hormone), leading to increased cravings and potential weight gain. • Cardiovascular Health: Quality sleep is linked to a lower risk of heart disease. During deep sleep, your blood pressure drops, allowing your heart to rest. Chronic sleep deprivation, on the other hand, can lead to increased blood pressure and elevated heart rates. Beyond physical health, sleep has a profound impact on mental well-being. The relationship between sleep and mental health is a two-way street: poor sleep can contribute to mental health issues, while mental health struggles can lead to sleep disturbances. • Cognitive Function: Good sleep is essential for optimal brain function. It enhances attention, problem-solving skills, and decision-making abilities. A well-rested mind is better equipped to manage stress and navigate daily challenges. • Emotional Regulation: Sleep affects mood and emotional resilience. During REM sleep, the brain processes emotions and memories. Insufficient REM sleep can lead to irritability and heightened emotional responses. • Mental Disorders: Sleep disorders often co-occur with mental health conditions like anxiety and depression. Addressing sleep issues can be a crucial step toward improving overall mental health. Next, let’s talk about some common sleep issues that come with age: 1. Waking up frequently — maybe to use the bathroom (looking at him) or because of discomfort. 2. Sleep apnea — breathing interruptions that can be serious if untreated. One of my sons has sleep apnea and it requires the use of a breathing mask while you sleep 3. Restless Leg Syndrome — ever feel like your legs have a mind of their own? 4. Insomnia — Insomnia isn’t just “not being able to sleep.” It can mean:
