What are muscle cramps?
Muscle cramps are sudden, involuntary contractions or spasms in one or more of your muscles. They are very common and often occur after exercise. Some people get muscle cramps, especially leg cramps, at night. They can be painful, and they may last a few seconds to several minutes.
You can have a cramp in any muscle, but they happen most often in the:
- Area along your ribcage
What causes muscle cramps?
Causes of muscle cramps include:
- Straining or overusing a muscle. This is the most common cause.
- Compression of your nerves, from problems such as a spinal cord injury or a pinched nerve in the neck or back
- Low levels of electrolytes such as magnesium, potassium, or calcium
- Not enough blood getting to your muscles
- Certain medicines
- Getting dialysis
Sometimes the cause of muscle cramps is unknown.
Who is at risk for muscle cramps?
Anyone can get muscle cramps, but they are more common in some people:
- Older adults
- People who are overweight
- Pregnant women
- People with certain medical conditions, such as thyroid and nerve disorders
When do I need to see a health care provider for muscle cramps?
Muscle cramps are usually harmless, and they go away after a few minutes. But you should contact your health care provider if the cramps:
- Are severe
- Happen frequently
- Don't get better with stretching and drinking enough fluids
- Last a long time
- Are accompanied by swelling, redness, or a feeling of warmth
- Are accompanied by muscle weakness
What are the treatments for muscle cramps?
You usually don't need treatment for muscle cramps. You may be able to find some relief from cramps by:
- Stretching or gently massaging the muscle
- Applying heat when the muscle is tight and ice when the muscle is sore
- Getting more fluids if you are dehydrated
If another medical problem is causing the cramps, treating that problem will likely help. There are medicines that providers sometimes prescribe to prevent cramps, but they are not always effective and may cause side effects. Talk to your provider about the risks and benefits of medicines.
Can muscle cramps be prevented?
To prevent muscle cramps, you can:
- Stretch your muscles, especially before exercising. If you often get leg cramps at night, stretch your leg muscles before bed.

What is sleep?
Sleep is a complex biological process. While you are sleeping, you are unconscious, but your brain and body functions are still active. They are doing a number of important jobs that help you stay healthy and function at your best. So when you don't get enough quality sleep, it does more than just make you feel tired. It can affect your physical and mental health, thinking, and daily functioning.
What are sleep disorders?
Sleep disorders are conditions that disturb your normal sleep patterns. There are more than 80 different sleep disorders. Some major types include:
- Insomnia - being unable to fall asleep and stay asleep. This is the most common sleep disorder.
- Sleep apnea - a breathing disorder in which you stop breathing for 10 seconds or more during sleep
- Restless leg syndrome (RLS) - a tingling or prickly sensation in your legs, along with a powerful urge to move them
- Hypersomnia - being unable to stay awake during the day. This includes narcolepsy, which causes extreme daytime sleepiness.
- Circadian rhythm disorders - problems with the sleep-wake cycle. They make you unable to sleep and wake at the right times.
- Parasomnia - acting in unusual ways while falling asleep, sleeping, or waking from sleep, such as walking, talking, or eating
Some people who feel tired during the day have a true sleep disorder. But for others, the real problem is not allowing enough time for sleep. It's important to get enough sleep every night. The amount of sleep you need depends on several factors, including your age, lifestyle, health, and whether you have been getting enough sleep recently. Most adults need about 7-8 hours each night.
What causes sleep disorders?
There are different causes for different sleep disorders, including:
- Other conditions, such as heart disease, lung disease, nerve disorders, and pain
- Mental illnesses, including depression and anxiety
Sometimes the cause is unknown.
There are also some factors that can contribute to sleep problems, including:
- Caffeine and alcohol
- An irregular schedule, such as working the night shift
- Aging. As people age, they often get less sleep or spend less time in the deep, restful stage of sleep. They are also more easily awakened.
What are the symptoms of sleep disorders?
The symptoms of sleep disorders depend on the specific disorder. Some signs that you may have a sleep disorder include that:
- You regularly take more than 30 minutes each night to fall asleep
- You regularly wake up several times each night and then have trouble falling back to sleep, or you wake up too early in the morning
- You often feel sleepy during the day, take frequent naps, or fall asleep at the wrong times during the day
- Your bed partner says that when you sleep, you snore loudly, snort, gasp, make choking sounds, or stop breathing for short periods
- You have creeping, tingling, or crawling feelings in your legs or arms that are relieved by moving or massaging them, especially in the evening and when trying to fall asleep
- Your bed partner notices that your legs or arms jerk often during sleep
- You have vivid, dreamlike experiences while falling asleep or dozing
- You have episodes of sudden muscle weakness when you are angry or fearful, or when you laugh
- You feel as though you cannot move when you first wake up
How are sleep disorders diagnosed?
To make a diagnosis, your health care provider will use your medical history, your sleep history, and a physical exam. You may also have a sleep study (polysomnogram). The most common types of sleep studies monitor and record data about your body during a full night of sleep. The data includes:
- Brain wave changes
- Eye movements
- Breathing rate
- Blood pressure
- Heart rate and electrical activity of the heart and other muscles
Other types of sleep studies may check how quickly you fall asleep during daytime naps or whether you are able to stay awake and alert during the day.
What are the treatments for sleep disorders?
Treatments for sleep disorders depend on which disorder you have. They may include:
- Good sleep habits and other lifestyle changes, such as a healthy diet and exercise
- Cognitive behavioral therapy or relaxation techniques to reduce anxiety about getting enough sleep
- CPAP (continuous positive airway pressure) machine for sleep apnea
- Bright light therapy (in the morning)
- Medicines, including sleeping pills. Usually, providers recommend that you use sleeping pills for a short period of time.
- Natural products, such as melatonin. These products may help some people but are generally for short-term use. Make sure to check with your health care provider before you take any of them.
