Sleep is important for your physical and emotional health. Sleep
may help you stay healthy by keeping your immune system strong.
Getting enough sleep can help your mood and make you feel less
stressed.
But we all have trouble sleeping sometimes. This can be for many
reasons. You may have trouble sleeping because of depression,
insomnia, fatigue, or Sjögren's syndrome. If you are depressed,
feel anxious, or have post-traumatic stress disorder (PTSD), you
may have trouble falling or staying asleep.
Whatever the cause, there are things you can do:
Your sleeping area
Your sleeping area and what you do during the day can affect how
well you sleep. Too much noise, light, or activity in your bedroom
can make sleeping harder. Creating a quiet, comfortable sleeping
area can help. Here are some things you can do to sleep
better.
Use your bedroom only for sleeping and sex.
Move the TV and radio out of your bedroom.
Keep your bedroom quiet, dark, and cool. Use curtains or blinds to
block out light. Consider using soothing music or a "white noise"
machine to block out noise.
Your evening and bedtime routine
Having an evening routine and a set bedtime will help your body get
used to a sleeping schedule. You may want to ask others in your
household to help you with your routine.
Don't do stressful or energizing activities in the evening.
Create a relaxing bedtime routine. You might want to take a warm
shower or bath, listen to soothing music, or drink a cup of
noncaffeinated tea.
Go to bed at the same time every night. And get up at the same time
every morning, even if you feel tired.
Use a sleep mask and earplugs, if light and noise bother you.
