YOU CAN LOSE WEIGHT without changing what you eat or doing one minute of exercise! It’s a bold claim. And don’t get me wrong: Nutrition and exercise are important! But there’s another key to weight loss – and most people don’t even know about it. It’s sleep.
In fact, besides eating whole foods and moving your body, getting enough sleep is the most important thing you can do for your health. On the flip side, sleep deprivation makes you fat – AND leads to depression, pain, heart disease, diabetes, and much more.
That’s why in today’s blog I want to talk about the impact sleep has on your health and give you 19 tips you can use to get a good night’s rest and enjoy all the health benefits sleep has to offer. Let’s start by talking about a rather serious sleep condition called sleep apnea.
The Dangers of Sleep Apnea
Sleep apnea is a condition where your sleep is interrupted all night because your airway closes and your body startles you awake so you don’t suffocate. This is a very common and extremely under-diagnosed problem. It affects 18 million Americans and most are NOT treated for it.
Let me tell you about one of my patients who was in that same predicament. He was so tired that he had to stand up at his computer to work during the day so he wouldn’t fall asleep! His wife reported hearing his horrible snoring and gasping episodes at night. He would fall right asleep as soon as he sat down to watch TV at night.
Most frightening, he had fallen asleep at the wheel when driving. Then he came to see me. When we got his sleep apnea diagnosed (with a sleep study in a sleep lab) and got him treated with a device to keep his airway open at night, he lost 50 pounds, his blood pressure turned to normal – and he got his life back.
But people with sleep apnea are not the only ones in trouble. It is estimated that 70 percent of Americans are sleep deprived. The era of Starbucks has been surpassed by an era of prescription stimulants to keep people awake and functioning, like dexadrine and Ritalin – otherwise known as “speed” or amphetamines.
Surprisingly, I see an increasing number of patients prescribed these “uppers” by their psychiatrist because coffee is not enough to keep them energetic. It seems we believe that if you can’t do ten things at once, something must be wrong with you. But this is preposterous.
Your biological rhythms keep you healthy and produce cyclic pulses of healing and repair hormones, including melatonin and growth hormone. When those rhythms are disturbed by inadequate or insufficient sleep, disease and breakdown get the upper hand.
It is estimated that 70 percent of Americans are sleep deprived.
We evolved along with the rhythms of day and night. They signal a whole cascade of hormonal and neurochemical reactions that keep us healthy by repairing our DNA, building tissues and muscle, and regulating weight and mood chemicals. The advent of the light bulb changed all that.
When you are sleep deprived, your cortisol rises – and so do all its harmful effects, including brain damage and dementia, weight gain, diabetes, heart attacks, high blood pressure, depression, osteoporosis, depressed immunity, and more.
The reality is that most of us need at least eight hours of restful sleep a night. But meeting this goal has become more and more difficult. Partially because good sleep is not something that just happens (unless you are a baby or teenager). There are clearly defined things that interfere with or support healthy sleep. Here is what you need to do:
19 Tips to Improve Sleep
First, you have to prioritize sleep! I used to think that “MD” stood for “medical deity” and meant I didn’t have to follow the same sleep rules as every other human being. I stayed up late working long shifts in the emergency room, ignoring the demands of my body to rest. It wasn’t until I learned that shift work (like I did in when I worked in the emergency room) leads to a shortened life expectancy that I quit.
Unfortunately, our lives are infiltrated with stimuli – and we keep stimulated until the moment we get into bed. This is not the way to get restful sleep. Frankly, it’s no wonder we can’t sleep well when we eat late dinners, answer emails, surf the Internet, or do work, and then get right into bed and watch the evening news about all the disaster, pain, and suffering in the world.
Instead we must take a little “holiday” in the two hours before bed. Creating a sleep ritual – a special set of little things you do before bed to help ready your system physically and psychologically for sleep – can guide your body into a deep, healing sleep.
We all live with a little bit of post-traumatic stress syndrome (or, I should say, traumatic stress syndrome, because for many of us there is nothing “post” about it). Much research has been done on the effects of stress and traumatic experiences and images on sleep. If you follow my guidelines for restoring normal sleep below, your post-traumatic stress may become a thing of the past.
Here’s how restore your natural sleep rhythm. It may take weeks or months, but using these tools in a coordinated way will eventually reset your biological rhythms:
Sleep Testing: What You Need to Know
There are many medical sleep disorders, the most common (and most under-diagnosed) is sleep apnea. If you experience excessive daytime sleepiness, fatigue, snoring, and have been seen to stop breathing in the middle of the night by your spouse or partner, then you could be one of the many people with undiagnosed sleep apnea.
People with sleep apnea have a higher risk of high blood pressure, heart disease, and sudden death, so diagnosing and treating it is imperative. High blood pressure is a clue, because half of all people with high blood pressure have undiagnosed sleep apnea.
Get an overnight sleep study done in a sleep lab. It may the best thing you ever do for yourself. It might just save your life!
And remember – don’t skimp on sleep! It is one of the most powerful healing treatments available if you want to achieve lifelong vibrant health.
