Sleep difficulties are a common problem for millions of adults. Even if you can get to sleep, you might have trouble staying asleep. Does this sound familiar? You drift off to dreamland, but find yourself wide awake at 3 a.m., or maybe you wake up every few hours throughout the night. Adequate sleep is supposed to leave you feeling refreshed and ready to start your day. But if your sleep is interrupted, you’re likely to feel fatigued and sleepy the next day. So what gives? There are several factors that may interfere with getting your zzz’s including the following:
1. Too much caffeine:
You probably already know caffeine is a stimulant and can affect your ability to fall asleep. But it can also lead to poor quality sleep including waking up in the middle of the night. Caffeine has a three to five-hour half-life, which means it takes your body that many hours to get rid of half the caffeine you consumed. The bottom line is you may feel the effects of caffeine several hours after you consume it. Keep in mind, energy drinks, cola, chocolate and certain teas also contain caffeine. Your best bet is to avoid caffeine about six hours before bed.
Stress and lack of sleep seem to go hand in hand. If you’re stressed, it can be hard to sleep well and may lead to middle of the night insomnia. When you don’t get enough sleep, that can also lead to more stress and it becomes a vicious cycle. According to the American Psychological Association, adults who get less than eight hours of sleep each night report higher levels of stress symptoms than those who sleep longer. Although it can be easier said than done, it’s important to unwind and unplug before bed.
3. Sleep environment:
Your sleep environment can contribute to poor sleep. For example, loud noises can jolt you from a sound sleep or light peeking through the shades can wake you. Fortunately, there are ways to make your bedroom more sleep-friendly. Invest in a quality mattress and comfy bedding and consider keeping your bedroom cool, which most people find helps sleep. Make sure your curtains are heavy enough to block out sunlight and use a white noise machine or earplugs to block sounds from outside.
4. An aching back:
Back pain can disrupt sleep and leave you struggling to find a comfortable position. If you have chronic back pain, it’s important to treat the underlying cause. Also, your sleep position can make a big difference in your comfort level. The right position for you may depend on whether your upper or lower back ache. To take the pressure off your back, the Mayo Clinic recommends sleeping on your side with your knees slightly pulled up towards your chest with a pillow between your knees.
Your hormones play a role in several functions including sleep. When there is an imbalance or a fluctuation, shifting hormones can contribute to sleep disturbances. A woman’s menstrual cycle, pregnancy, perimenopause and menopause often cause hormonal changes that may affect their quality of sleep. For example, decreased estrogen can lead to hot flashes, which wake you up at 2 a.m. You can’t always control your hormones, but you can make your environment conducive for sleep, unwind before bed and stick to the same sleep schedule. If those strategies don’t help, talk with your doctor. Hormonal replacement therapy or additional treatment may be an option.
If you enjoy a cocktail before bedtime, you know alcohol may help you get to sleep. But the bad news is it actually can interfere with your quality of sleep. As the alcohol metabolizes and the effects wear off, it prevents deep sleep, which causes restless sleep throughout the night. Consider limiting alcohol a few hours before you hit the sack.
7. Eating too late:
A light midnight snack may be fine, but a heavy meal too close to bedtime may leave you tossing and turning during the night. Eating large portions before you turn in for the night can lead to indigestion and acid reflux. If you want a snack before bed, keep it light and stay away from spicy and greasy foods.
