Get plenty of sleep

As you get older, getting good sleep becomes more important. Getting enough sleep can enhance memory, focus, and brain function. On the other hand, a lack of sleep can lead to a variety of problems, including a decrease in the immune system's effectiveness.

Try one of these methods to improve the quality of your sleep:

• Make sure your room is dark, quiet, and cool
• Keep a regular bedtime routine when possible
• Limit daytime naps to about 45 minutes
• Avoid caffeine later in the day
• Limit alcohol, as it may interfere with sleep quality

Ideally, our bodies require seven to nine hours of quality sleep to recharge and keep our immune systems strong. Consult your doctor if you suffer from insomnia or other issues that keep you up at night to determine whether there may be any underlying causes.
