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. Poor sleep has been linked with dementia; 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. Adults who don’t get enough sleep 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

• watching TV or using the computer or cell phone 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.

Humans are social creatures. We need human contact to survive and thrive. It is also vital for healthy brain function. Lack of friendly interactions has been linked with cognitive decline. Perceived social isolation and loneliness are risk factors for poorer cognitive performance, depression, and faster cognitive decline. People who have friends, even a few close friends, are less likely to develop Alzheimer’s disease and brain decline. They are also happier and more productive. If you would like to meet new people, take up some social hobbies where you can meet others. Dancing, tennis, and bridge are a few examples of activities where you can get out and meet new people.
