What Are Sleep Disorders?
These conditions affect how much and how well you sleep. Causes range from poor habits that keep you awake to medical problems that disrupt your sleep cycle. If you don't feel rested in the mornings, see your doctor. Not getting enough shuteye is a serious problem that can threaten your health and safety.
The Dangers of Not Getting Enough ZZZs
Lack of sleep can take a toll on nearly every part of your life. Research links sleep deprivation to car accidents, relationship troubles, poor job performance, job-related injuries, memory problems, and mood disorders. Recent studies also suggest sleep disorders may contribute to heart disease, obesity, and diabetes.
Symptoms of a Sleep Disorder
Symptoms depend on the type you have, but you might:
- Feel very sleepy during the day
- Have trouble falling or staying asleep
- Stop breathing briefly and often while asleep (apnea)
- Have uncomfortable feelings in your legs and the urge to move them (restless legs syndrome)
How Much Shuteye Do You Need?
Needs vary from person to person, but the general guidelines are:
- 16 hours for infants
- 9 hours for teenagers
- 7-8 hours for adults
Keep in mind that some adults do fine with 5 hours, while others need as many as 10.
It’s normal to have trouble sleeping once in a while, but when the problem lingers night after night, you have insomnia. Do you lie awake for hours? Do you wake up too early and not able to drift off again? Do you wake up repeatedly throughout the night? Insomnia is the most common sleep disorder ,affecting a third of adults at some point in their lives.
Insomnia and Sleep Hygiene
In many cases, insomnia is related to bad habits before bed. Do you drink coffee in the afternoon or evening? Do you smoke or eat heavy foods at night? Do you go to bed at a different time each night? Do you fall asleep with the television on?
Insomnia and Mental Health
Mental health problems such as depression, anxiety, and posttraumatic stress disorder can also cause insomnia. Unfortunately, some of the medications used to treat these conditions can also cause sleep problems. If you think you’re losing ZZZs and your medication is to blame, talk to your doctor about adjusting your treatment.
Insomnia and Medical Conditions
Trouble sleeping is often linked to health problems such as:
- Chronic pain
- COPD (Chronic Obstructive Pulmonary Disease)
- Heart failure
- Thyroid problems
- Neurological disorders such as stroke, Alzheimer's, or Parkinson's
Pregnancy is another reason for insomnia, especially in the first and third trimesters. Menopause is, too, as hot flashes are uncomfortable. Both men and women tend to have sleep problems after 65. And shift workers and frequent flyers can get a circadian rhythm disorder. This means their “internal body clock” is out of whack.
This means your breathing stops and starts over and over while you’re sleeping. The pauses last several seconds and trigger a switch from deep to light sleep. Apnea can make you very sleepy during the day. You might not even know you have it. But your spouse or partner can certainly tell you about your snores, snorts, and gasps.
Restless Legs Syndrome
Do you have an irresistible urge to move your legs? Do you have uncomfortable feelings in them, like a throb or tingle? Many describe it as pins and needles or a creepy-crawly sensation. It gets worse at night, which makes it tough to catch some winks. And you might have twitches that wake you up.
Do you find it hard to get through the day without naps, even after a good night’s rest? With narcolepsy, you can’t control it and suddenly fall asleep. Other warning signs include:
- Loss of muscle control with strong emotions
- Dream-like hallucinations as you fall asleep or wake up
- Dreams during naps
- When you wake up, you might also feel like you can’t move.
Do you get out of bed and wander around at night without knowing it? Do people tell you the next morning about your crazy adventures, things you don’t remember? It’s most common in children between the ages of 4 and 8, but it can happen to anyone.
If you think you have a sleep disorder, tell your doctor. He might ask you to write down your habits for 1-2 weeks. Include:
- What time you got in and out of bed
- How long and how well you slept
- The amount of time you laid awake
- What you ate/drank (especially caffeine and alcohol) and when
- Your emotions and stress level
- A list of drugs you take
For sleep apnea, a continuous positive airway pressure (CPAP) machine keeps airways open so you can rest soundly. You can treat narcolepsy and restless legs syndrome with lifestyle changes and prescription medication. And there are drugs for insomnia, although good sleep habits can work just as well.
Anxiety makes insomnia worse, but cognitive-behavioral therapy can help ease your worries. Relaxation training and biofeedback calm your breathing, heart rate, muscles, and mood. Talk therapy can also quiet your mind.
Good Sleep Habit:
You can do several things to prep for bedtime, and a regular workout should be a part of your plan. It’s easier to fall and stay asleep when your body’s tired. Exercise in the late afternoon though. Working up a sweat just hours before bedtime can have the opposite effect and keep you up.
Some foods and drinks can be the stuff of nightmares. Avoid these 4-6 hours before bed:
- Caffeine, including coffee, tea, and soda
- Heavy or spicy foods
- Alcohol (it helps some people fall asleep, but it can also make them wake up over and over again)
Try a light evening snack that’s high in carbs and easy to digest. A small bowl of cereal with milk or a small muffin fit the bill, but eat them at least an hour before calling it a day. Warm milk and chamomile tea raise your body temperature and can make you sleepy, too.
Is late-night TV part of your routine? Sure, it’s entertaining, but it also keeps you awake and alert. Playing video games and surfing the Internet can have the same effect. The National Sleep Foundation suggests that you remove televisions and computers from your bedroom.
Tell your mind and body that it's time to catch some ZZZs with a bedtime ritual. This can include a warm bath, a book, or relaxation techniques such as deep breathing. It's also important to go to bed and wake up at the same time every day, even on the weekends. If you still have trouble sleeping, talk to your doctor.
