We all have some bad habits, but some of these bad habits can harm your brain. Skimping on sleep is one of those bad habits. Those who do not get enough Zzzs are more likely to get dementia and Alzheimer’s compared to those who get adequate sleep. Lack of sleep in older adults increases the risk of excessive daytime sleepiness, depression, and problems with attention and memory. They are also more likely to fall at night and rely on more sleep aids (both over-the-counter and prescription kinds). People who have trouble falling asleep at night should avoid caffeine, alcohol, and watching TV or using the computer in the evening. If you have trouble sleeping, practice a soothing bedtime routine in the evening to help you wind down and get to sleep.
