• Increased risk of chronic diseases: Persistent lack of sleep can increase the risk of chronic diseases, including cardiovascular disease, type 2 diabetes, and high blood pressure. Poor sleep increases stress hormone (cortisol) levels and can cause blood sugar disruption, leading to long-term health problems.
• Reduced metabolism: Not getting enough sleep affects the body’s metabolism, disrupting hormones that control hunger and fullness such as ghrelin and leptin. This can lead to uncontrolled eating, increased cravings, especially for foods high in sugar and fat, easily causing weight gain and obesity.
• Effects on skin and appearance: Lack of sleep reduces the ability to regenerate skin, causing skin to become dull, pale and prone to acne. Dark circles under the eyes and wrinkles appear more easily because the body does not have time to recover and regenerate collagen – an important protein that helps the skin stay firm and elastic. Lack of sleep can also make the face look tired and poor, affecting appearance and confidence.

Sleep plays an extremely important role in human physical and mental health.

However, in modern life with a fast pace and lots of pressure, getting enough sleep seems to be becoming increasingly difficult for many people. So What are the harmful effects of not getting enough sleep?? Lack of sleep not only affects physical health but also has many negative effects on the brain and mind:

• Impaired concentration and memory: Not getting enough sleep reduces the ability to concentrate, remember and process information. Sleep helps consolidate memories, create new connections in the brain, and transfer information from short-term memory to long-term memory. Lack of sleep reduces the ability to remember, learn and solve problems.
• Mood disorders and increased risk of depression: Lack of sleep makes mood more volatile, irritable and sensitive. Poor sleep reduces serotonin, a hormone that helps regulate mood, thereby increasing the risk of anxiety and depression. Long-term sleep disorders, especially chronic insomnia, are considered a major risk factor for psychological health problems.
• Affects the ability to make decisions and control emotions: When lacking sleep, the brain operates less effectively, affecting the ability to evaluate situations and make decisions. Brain areas such as the prefrontal cortex – which controls reason, judgment and decisions – slow down. At the same time, lack of sleep reduces the ability to control emotions, making people who lack sleep more easily angry, susceptible to negative impacts, and more difficult to control themselves.
• Increased risk of long-term brain diseases: Prolonged lack of sleep can increase the risk of serious brain diseases such as cognitive decline and Alzheimer’s disease. During sleep, the brain removes accumulated toxic substances, including beta-amyloid, a protein linked to Alzheimer’s disease. Lack of sleep prevents these toxins from being fully eliminated, creating conditions for brain diseases to develop.
