We live in crazy busy times. It seems the technology designed to make us more efficient has allowed us to continue our work life after hours and jam more play dates into our over-packed schedules. We attempt to keep up with family, work, home, friends and our health. Polls show we’re also spending more time than ever trying to improve our appearance, lose weight and prioritize our health. Something’s gotta give—and unfortunately, for man, trying to squeeze a few extra hours out of the day comes at the cost of shorter nights and less sleep.
Sleep is crucial for memory and learning, immune system functioning, emotion regulation, heart health, muscle repair and growth, healthy aging and regulating hunger. Mental and physical performance is directly and dramatically impacted by poor sleep. Scientists are discovering new evidence of the incredible power of sleep every day.
Healthy sleep is important for healthy weight loss. There are two important hormones that regulate our appetite, which may be the most significant factor in weight gain or loss. Ghrelin is our “hunger hormone,” that regulates our appetite and energy distribution. Leptin is our satiety hormone; it signals when we’re full and have eaten all we need.
Not getting enough sleep, or poor quality sleep, revs your appetite by boosting ghrelin and lowering leptin. You wake up feeling hungrier after a rough night’s sleep and your body isn’t able to send you the property hunger/satiety signals:
Short sleep = HIGHER ghrelin + LOWER leptin à eat more à weight GAIN
Long sleep = LOWER ghrelin + HIGHER leptin à eat less àweight LOSS/STABILITY

We spend nearly a third of our lives asleep. How much sleep we need is fairly stable across our adult lifespan. Adults generally need between 7 to 9 hours of sleep each night; some may need slightly less and others slightly more.
