## Aging brain changes sleep timing
Older people wake up earlier because their brains process time cues less effectively as they age.

> Like most of the things that change with age, there’s not just one reason, and they are all interconnected
## Time cues from the brain decline
The brain’s ability to sense sunset, sunlight, meals, and social cues that mark daily time decreases with age.

> These are all what we call time givers, or they give time to the brain
## Cataracts affect sleep timing
People with cataracts, which affect over 50% of Americans aged 80 and up, perceive sunset earlier due to reduced light.

> If there’s cataracts, the evening light doesn’t go into the eyes as much, so, according to the brain, sunset is earlier than when it actually set
## Melatonin release happens earlier
Less light input causes the body to release melatonin earlier, making older people feel tired sooner.

> For younger people, melatonin 'starts rising after sunset', which is why you generally feel tired a few hours after
## Bright light helps sleep timing
Exposure to bright light 30 to 60 minutes before sunset can delay wake times by helping the brain sense later sunsets.

> These bright lights will tell the brain that the sun hasn’t set yet, which will hold the melatonin production
## Sleep tips for older adults
Avoid alcohol before bed, exercise regularly, and get morning sunlight to improve sleep quality and duration.

> While that nightcap might make you sleepy, it actually disrupts the quality of your sleep
## Sleep changes are natural
Changes in sleep patterns are part of aging, but healthy habits can counteract them for better rest.

> All in all, changes in sleep patterns are a part of life. While some of these factors are out of your control, you can also counteract them with healthy habits so you can get your best rest
## Key takeaway

Aging brains receive less light, causing earlier melatonin release and earlier wake times.
