SHOULD I EXERCISE TO SLEEP BETTER?
Sleepless nights happen to the best of us. Maybe you tossed and turned all night long, were up working on an urgent deadline or had a bit too much fun celebrating last night and it ate into your shuteye. Whatever the case, the reality is that you still have to face the next day on little to no sleep and still function at an acceptable level.
What Causes Insomnia?
Insomnia can be caused by psychiatric and medical conditions, unhealthy sleep habits, specific substances, and/or certain biological factors. Recently, researchers have begun to think about insomnia as a problem of your brain being unable to stop being awake (your brain has a sleep cycle and a wake cycle—when one is turned on the other is turned off—insomnia can be a problem with either part of this cycle: too much wake drive or too little sleep drive). It’s important to first understand what could be causing your sleep difficulties.
Medical Causes of Insomnia
There are many medical conditions (some mild and others more serious) that can lead to insomnia. In some cases, a medical condition itself causes insomnia, while in other cases, symptoms of the condition cause discomfort that can make it difficult for a person to sleep.
Examples of medical conditions that can cause insomnia are:
- Nasal/sinus allergies
- Gastrointestinal problems such as reflux
- Endocrine problems such as hyperthyroidism
- Neurological conditions such as Parkinson’s disease
- Chronic pain
- Low back pain
Medications such as those taken for the common cold and nasal allergies, high blood pressure, heart disease, thyroid disease, birth control, asthma, and depression can also cause insomnia.
In addition, insomnia may be a symptom of underlying sleep disorders. For example, restless legs syndrome—a neurological condition in which a person has an uncomfortable sensation of needing to move his or her legs—can lead to insomnia. Patients with restless legs syndrome typically experience worse symptoms in the later part of the day, during periods of inactivity, and in the transition from wake to sleep, which means that falling asleep and staying asleep can be difficult. An estimated 10 percent of the population has restless legs syndrome.
Sleep apnea is another sleep disorder linked to insomnia. With sleep apnea, a person’s airway becomes partially or completely obstructed during sleep, leading to pauses in breathing and a drop in oxygen levels. This causes a person to wake up briefly but repeatedly throughout the night. People with sleep apnea sometimes report experiencing insomnia.
If you have trouble sleeping on a regular basis, it’s a good idea to review your health and think about whether any underlying medical issues or sleep disorders could be contributing to your sleep problems. In some cases, there are simple steps that can be taken to improve sleep (such as avoiding bright lighting while winding down and trying to limit possible distractions, such as a TV, computer, or pets). While in other cases, it’s important to talk to your doctor to figure out a course of action. You should not simply accept poor sleep as a way of life—talk to your doctor or a sleep specialist for help.

The Best Exercises for Sleep
Working out regularly has so many positive health benefits. It can reduce stress, boost alertness during the day, and even improve your sleep quality. There’s no one perfect exercise that will enhance your sleep—any type of movement is better than none—but these three specific activities are scientifically proven to help you get better slumber.
Aerobic (or Cardio) Exercise
Activities that get your heart rate up, such as running, brisk walking, cycling, and swimming, have been shown to improve sleep and battle insomnia. Even small bouts, such as 10 minutes, may help, though the goal is to get at least 150 minutes of moderate-intensity (or 75 minutes of vigorous-intensity) aerobic exercise each week.
Building muscle has been shown to improve the quality of sleep, and it can also help you fall asleep faster and wake up less frequently throughout the night. So try doing exercises like shoulder presses, bicep curls, tricep dips, squats, lunges, calf raises, sit-ups, and push-ups that will make you stronger.
Yoga’s relaxing poses and stretches, as well as the calming breathing exercises that accompany them, may be especially helpful if stress is what’s keeping you from falling asleep. Those with insomnia who do yoga daily for eight weeks are likely to fall asleep faster and increase the amount of time that they spend sleeping.
