Self-care is any necessary human regulatory function which is under individual control, deliberate and self-initiated.

Personal hygiene involves those practices performed by an individual to care for one's bodily health and well being, through cleanliness. Practices that are generally considered proper hygiene include bathing regularly, washing hands regularly and especially before handling food, washing scalp hair, wearing clean clothing, brushing teeth, cutting finger nails, covering one's mouth when coughing, disposal of soiled tissues appropriately, making sure toilets are clean, and making sure food handling areas are clean, besides other practices. People tend to develop a routine for attending to their personal hygiene needs.

Sleep hygiene recommendations include establishing a regular sleep schedule, using naps with care, not exercising physically or mentally too close to bedtime, limiting worry, limiting exposure to light in the hours before sleep, getting out of bed if sleep does not come, not using bed for anything but sleep and sex, avoiding alcohol as well as nicotine, caffeine, and other stimulants in the hours before bedtime, and having a peaceful, comfortable and dark sleep environment.
