Sleep is not just a time when our body and mind shut down. It’s an active period during which essential processing, restoration, and strengthening occur. Just as our body needs food and water to function, it also needs sleep. Without enough sleep, our bodies can’t work correctly. Sleep helps our body repair itself. During sleep, our cells produce more protein. Sleep is often called “beauty sleep” – it helps our body repair and rejuvenate. Lack of sleep can disrupt the hormones that control hunger and fullness. When we don’t get enough sleep, we eat more and choose unhealthy foods.
Sleep and mental health
Sleep is closely connected to mental and emotional health. Most people have experienced fatigue, short temper, and lack of focus, often resulting from a poor night’s sleep. What many people don’t realize is that chronic sleep problems can lead to long-term mood disorders like depression and anxiety. During sleep, our brain processes and consolidates our memories from the day. This is why students who pull “all-nighters” often struggle to recall information during exams. Sleep also helps regulate our emotions. When well-rested, we can better handle stress and manage our emotions.
Sleep cycle
Understanding the sleep cycle can help us appreciate why quality sleep is essential. Sleep is not a uniform state of unconsciousness. Instead, we go through several stages of sleep throughout the night. There are two main types of sleep: Rapid Eye Movement (REM) sleep and Non-REM sleep. Non-REM sleep has three stages, progressing from light sleep to deep sleep. REM sleep is when most dreaming occurs and is thought to play a crucial role in learning and memory consolidation. A complete sleep cycle takes about 90 to 110 minutes. We must go through several complete sleep cycles each night for optimal health. This is why it’s not just the quantity of sleep that matters but also the quality.
How much sleep do we need?
The amount of sleep we need varies with age. Newborns need up to 17 hours of sleep daily, while school-age children and teens need 9 to 11 hours. Most adults need 7 to 9 hours of sleep per night. However, it’s important to note that these are general guidelines. Some people may need more or less sleep to feel their best. You might need more sleep if you’re often tired, irritable, or have trouble concentrating.
Incidences of sleep deprivation
- Heart disease – Lack of sleep can increase blood pressure and inflammation, which are risk factors for heart disease.
- Diabetes – Poor sleep can affect how our body processes glucose, increasing the risk of type 2 diabetes.
- Obesity – As mentioned earlier, lack of sleep can disrupt hormones that control appetite, leading to weight gain.
- Mental health disorders – Chronic sleep problems are linked to depression, anxiety, and other mental health issues.
- Accidents – Drowsy driving can be as dangerous as drunk driving. Many workplace accidents are also attributed to fatigue.
