Habits are repeated behaviors that can become closely connected with particular situations, emotions or routines. Some are harmless, while others can affect health or daily life. Changing an unwanted habit usually requires understanding what triggers it and finding a realistic alternative.

Smoking

Smoking is harmful to health and increases the risk of serious diseases, including cardiovascular disease, respiratory disease and several cancers. Nicotine dependence can make quitting difficult, so needing support is not a sign of weak willpower.

Evidence-based stop-smoking support may include counseling and, where appropriate, medicines or nicotine-replacement treatment recommended by a healthcare professional.

Nail Biting

Nail biting is common and should not be treated as a reason to shame someone. If a person wants to reduce it, identifying situations that trigger the behavior, keeping nails maintained and substituting another activity for the hands may help. Persistent biting that causes injury or significant distress can be discussed with a healthcare professional.

Eating Habits

Occasionally eating more than intended is different from having an eating disorder. Regular eating patterns, adequate nutrition and awareness of hunger and fullness cues may help some people develop a healthier relationship with food. Recurrent loss of control, distress or other concerns around eating deserve professional support rather than judgment.

Changing a Routine

Choose one specific behavior, identify its triggers and decide what you will do instead. Small changes that can be repeated are usually more practical than demanding instant perfection. If a habit involves addiction, significant anxiety, self-injury or an eating disorder, qualified professional support is appropriate.
