Many of us try to sleep as little as possible. There are so many things that seem more interesting or important than getting a few more hours of sleep, but just as exercise and nutrition are essential for optimal health and happiness, so is sleep. The quality of your sleep directly affects the quality of your waking life, including your mental sharpness, productivity, emotional balance, creativity, physical vitality, and even your weight. No other activity delivers so many benefits with so little effort!

The effects of sleep deprivation and chronic lack of sleep
While it may seem like losing sleep isn't such a big deal, sleep deprivation has a wide range of negative effects that go way beyond daytime drowsiness. Lack of sleep affects your judgment, coordination, and reaction times. In fact, sleep deprivation can affect you just as much as being drunk.

The effects include:

• Fatigue, lethargy, and lack of motivation
• Moodiness and irritability
• Reduced creativity and problem-solving skills
• Inability to cope with stress
• Reduced immunity; frequent colds and infections

• Concentration and memory problems
• Weight gain
• Impaired motor skills and increased risk of accidents
• Difficulty making decisions
• Increased risk of diabetes, heart disease, and other health problems

How sleep deprivation can add to your waistline
Ever noticed how when you’re short on sleep you crave sugary foods that give you a quick energy boost? There’s a good reason for that. Sleep deprivation has a direct link to overeating and weight gain.

There are two hormones in your body that regulate normal feelings of hunger and fullness. Ghrelin stimulates appetite, while leptin sends signals to the brain when you are full. However, when don’t get the sleep you need, your ghrelin levels go up, stimulating your appetite so you want more food than normal, and your leptin levels go down, meaning you don’t feel satisfied and want to keep eating. So, the more sleep you lose, the more food your body will crave.
