The promotion of regular sleep is known as sleep hygiene. Here are some simple sleep hygiene tips:
- Go to bed at the same time each night, and rise at the same time each morning.
- Sleep in a quiet, dark, and relaxing environment, which is neither too hot nor too cold.
- Make your bed comfortable and use it only for sleeping and not for other activities, such as reading, watching TV, or listening to music.
- Remove all TVs, computers, and other "gadgets" from the bedroom.
- Avoid large meals before bedtime.
You can promote sleep hygiene by sending a sleep Health e-Card.
Sleep-related difficulties – typically called sleep disorders – affect many people. Major sleep disorders include:
- Insomnia – an inability to fall or stay asleep that can result in functional impairment throughout the day.
- Narcolepsy – excessive daytime sleepiness combined with sudden muscle weakness; episodes of narcolepsy are sometimes called "sleep attacks" and may occur in unusual circumstances.
- Restless Legs Syndrome (RLS) – an unpleasant "creeping" sensation associated with aches and pains throughout the legs that can make it difficult to fall asleep.
- Sleep Apnea – interrupted sleep caused by periodic gasping or "snorting" noises or momentarily suspension of breathing.
If you or someone you know is experiencing a sleep disorder, it may be important to receive an evaluation by a healthcare provider.
