How To Prevent Sleep Fragmentation And Insomnia?

Sleep fragmentation is basically when you have short sleep intervals. You have repeated sleep interruptions all through the night. This sleep pattern leads to extreme tiredness during the day.

People with fragmented sleep usually fall asleep on time but wake up several times through the night. Sleep fragmentation is often one of the symptoms of sleep disorders like sleep apnea or narcolepsy.

Also, experiencing body ache or pain can result in sleep fragmentation as the pain might cause you to wake up intermittently during the night. Another thing that can cause sleep fragmentation is snoring.

The major effect of sleep fragmentation is excessive fatigue throughout the day. Sleep fragmentation can also result in unhealthy weight gain and mood disorder.

To know if you are experiencing sleep fragmentation, you can use sleep trackers to help you determine how often you wake up between sleep and for how long.

Along with the help of a sleep physician, this would help you determine if you are suffering from sleep fragmentation or something else.

If your sleep fragmentation is a result of a sleep disorder, then the treatment involves treating the underlying sleep disorder. Sleep physicians also recommend the following to help treat sleep fragmentation:

  • Go to bed and wake up at approximately the same time every day
  • Avoid using electronic gadgets like phones and laptops an hour before your bedtime.
  • Sleep in a comfortable, cool, quiet, and dark environment.
  • Physicians also recommend supplements like melatonin and valerian to help reduce sleep fragmentation
  • Cognitive-behavioral therapy, sleep restriction therapy, and relaxation training can help in treating fragmented sleep.

Insomnia can be caused by physical or psychological factors. Also, a snoring partner, pregnancy, parasite, or genetic condition can cause insomnia.
