Tips for better sleep:

Increase your physical activity — and make it a morning routine.

Exercising in the morning can “help jump start your day,” St-Onge said. Plus, the exposure to light is good for your circadian rhythm, a natural, internal process that controls the sleep-wake cycle.Of course, any exercise is better than none, so work out later in the day if that works best for you.

Eat a healthy diet.

Enjoy plenty of fiber-rich vegetables, fruits, legumes and whole grains. Include nuts and fish. Minimize processed meats, refined carbohydrates and sugary drinks. Avoid trans fats.

This eating style will help you live a longer, healthier life and may help improve your sleep. One study found that eating more saturated fat and sugar led to less deep sleep, and eating more fiber led to more deep sleep.

Balance your calories throughout the day.

When you get more calories late at night, sleep may be less peaceful, St-Onge said. Drinking too many sugary, caffeinated or alcoholic beverages may also lead to more disruptions during the night.

Keep in mind that your dietary needs may change with age. For example, you may be more affected by caffeine as you get older. You might need to have your last cup of coffee earlier in the day, especially if it’s keeping you up at night.

Find a relaxing ritual.

If stress is taking a toll on your sleep, find practices to help you relax. These can include meditation, deep breathing or writing.

Gratitude may help you sleep better, according to some research, so try a gratitude practice or journal.

“I’m a list maker, so when I’m stressed I look at my calendar. That’s what calms me down,” St-Onge said.

Take a look at how your late-night habits may be affecting your sleep.

“You need to prioritize what’s more important. Do you really need this right now?” she said. “Was that extra hour of work late at night worth it? Was staying up later beneficial? Or did it make you more stressed the next day?”

Go low-tech.

If you’re seeking better sleep, try not using cell phones and other devices late in the evening. St-Onge gives her phone a bedtime: It’s off from 10 p.m. to 7 a.m. every day.
“Shining a bright light in your face before bedtime is counterproductive,” she said.

Keep trying.

Some of these lifestyle changes are based on personal preference and it may take some trial and error to find what works best for you.

Apps and watches that monitor sleep can be helpful, but not foolproof.
