The Foundations of a Healthy Lifestyle
A healthy lifestyle is built from repeatable habits, not a restrictive trend. Balanced food, regular physical activity and adequate sleep support health and can lower the risk of some chronic conditions. Screening can identify certain problems earlier, but which test is appropriate depends on age, sex, symptoms, family history, pregnancy status, existing conditions and local programme guidance.
Nutrition: The ICMR Guidelines in Practice
ICMR-NIN's 2024 guidance emphasizes a varied, balanced pattern. Build meals from vegetables and fruit; whole grains or millets; pulses, beans or another suitable protein food; and other foods appropriate to your needs. Prefer minimally processed choices more often and limit foods high in fat, salt or sugar and highly processed products. The right quantities vary with age, activity, health, pregnancy and other individual needs; use a clinician or dietitian for a therapeutic diet rather than assuming a universal oil, protein or supplement dose.
Physical Activity and Sedentary Time
For adults generally, WHO recommends 150 to 300 minutes of moderate-intensity aerobic activity a week, or 75 to 150 minutes of vigorous activity, or an equivalent combination. Adults should also do muscle-strengthening activity involving major muscle groups on at least 2 days a week. Limit sedentary time and replace it with physical activity of any intensity, including light intensity. To help reduce the harms of high sedentary time, adults should aim to do more than the recommended moderate- to vigorous-intensity activity when possible. During pregnancy or postpartum, women without contraindications should aim for at least 150 minutes of moderate-intensity aerobic activity each week. Vigorous activity is a continuation option only for women who were already habitually doing vigorous activity before pregnancy and have no contraindication; ask a clinician about safe adaptations during pregnancy or postpartum. Adults aged 65 and older follow the same general-adult aerobic and strengthening targets and should also do varied multicomponent activity that emphasizes functional balance and strength at moderate or greater intensity on at least 3 days a week to improve functional capacity and help prevent falls. Some activity is better than none: start gradually and adapt activity to current ability and fall risk. Choose walking, cycling, sport, household movement or adapted home exercise that is safe for your health, weather, air quality and surroundings; ask a clinician or physiotherapist about adaptations if fall risk, symptoms or a medical condition affects what is safe.
The Importance of Sleep Hygiene
Sleep needs vary with age and the person. CDC guidance says adults aged 18 to 60 need at least 7 hours a night, adults 61 to 64 generally need 7 to 9 hours, and adults 65 or older generally need 7 to 8 hours. A regular sleep and wake time, a quiet and comfortable environment and a wind-down routine can help. Speak with a healthcare professional if sleep problems persist or daytime sleepiness, loud snoring, gasping or another symptom concerns you.
Preventive Health Screenings
India's NP-NCD programme uses population-based screening and risk assessment for hypertension, diabetes and oral cancer in adults aged 30 and over, with breast and cervical cancer screening for eligible women. This programme scope is not a universal schedule for every laboratory test. Other tests and their frequency depend on age, sex, symptoms, family history, previous results and clinician or programme guidance. Screening does not guarantee prevention or mean prescribed treatment can be stopped; discuss results and next steps with a healthcare professional.
