Sleep! It's more important than you think

Many people have trouble sleeping, and breaking the cycle of insomnia can be hard. But lack of sleep can lead to a whole lot of trouble, the least of which is excessive yawning. Read on to read why lack of sleep can wreak havoc on your regular functioning.

WHY IS SLEEP SO IMPORTANT

During sleep, pathways form between nerve cells (neurons) in your brain that help you remember new information you’ve learned. Sleep deprivation leaves your brain exhausted, so it can’t perform its duties as well. You may also find it more difficult to concentrate or learn new things. The signals your body sends may also come at a delay, decreasing your coordination skills and increasing your risks for accidents.

EMOTIONAL AFFECT

Sleep deprivation also negatively affects your mental abilities and emotional state. You may feel more impatient or prone to mood swings. It can also compromise decision-making processes and creativity.

WEIGHT GAIN

Along with eating too much and not exercising, sleep deprivation is another risk factor for becoming overweight and obesity. Sleep affects the levels of two hormones, leptin and ghrelin, which control feelings of hunger and fullness.

Leptin tells your brain that you’ve had enough to eat. Without enough sleep, your brain reduces leptin and raises ghrelin, which is an appetite stimulant. The flux of these hormones could explain nighttime snacking or why someone may overeat later in night. A lack of sleep can also contribute to weight gain by making you feel too tired to exercise.

Your body needs sleep, just as it needs air and food to function at its best. During sleep, your body heals itself and restores its chemical balance. Your brain forges new connections and helps memory retention. Without enough sleep, your brain and body systems won’t function normally. Stimulants like caffeine aren’t enough to override your body’s profound need for sleep. Behind the scenes, chronic sleep deprivation can interfere with your body’s internal systems and cause more than just the initial signs and symptoms listed above.
