Growing old has a genius PR team. It sells blue-light masks, tinctures, and freezer pods for people who really hate the idea of youth slipping away.
But the truth is, it’s not a serum or a capsule that can keep you feeling young. Experts keep pointing to the same five moves that influence biological age, the cellular wear-and-tear version of time that predicts health better than the number on your cake.
Here are five habits that actually slow the clock:
1) Take your sleep seriously
Sleep is repair. It resets hormones, clears cellular junk, and supports immune and brain function. Better sleep lines up with slower epigenetic aging, while short or fragmented sleep tracks with faster clocks and a higher risk for diabetes, heart disease, and dementia. Aim for regular hours, seven to nine if possible. Keep the room dark and cool. Park the phone outside.
2) Move more, most days
Exercise is the closest thing to a lever on biological age. Even simple multi-week programs shift aging markers. Mix strength and endurance three to four times a week. Brisk walks, short lifts, bike intervals. Consistency beats heroics. If you sit all day, stand up every hour, and take the stairs whenever you can.

3) Eat for the clock you want
Eating habits heavy on plants, fiber, and healthy fats link to younger biological profiles, especially if weight or blood sugar is an issue. Build plates from vegetables, fruit, whole grains, legumes, nuts, fish, and olive oil. Dial down ultra-processed foods, added sugars, and excess sodium. You’re stocking cells with materials that repair damage and keep stress signals low.
4) Audit your vices
Smoking and heavy drinking carve lines into your DNA. Both accelerate biological age across multiple measures. If quitting nicotine feels impossible, get help and keep trying. With alcohol, set a weekly limit and schedule alcohol-free days. Your liver, heart, and sleep will pay you back with interest you can feel.
5) Protect your stress budget
Chronic stress is a full-body tax. It throws hormones off balance, weakens immunity, interferes with sleep, and speeds up biological aging. Night shifts and endless workweeks only make the toll heavier. Build margins into your week. Ten minutes of breathing or meditation, therapy when you need it, a walk with someone who makes you laugh, a firm no when your schedule is already full.
We carry two ages. Chronological age is non-negotiable. Biological age has some wiggle room. These habits change the slope of the line. They’re inexpensive, repeatable, and addictive in the right way. No pill beats a routine you can live with. Sleep well. Move often. Eat like someone you care about. Be honest about the habits that wear you down. Then keep going. The anti-aging industry sells shortcuts. Your body prefers a schedule with routine maintenance.
