Aging and Sleep​

It is a myth that older people need less sleep. Aging is associated with several changes in sleep
patterns. Seniors often go to bed early and wake up early, this is due
to phase advance of the normal circadian rhythm. They also wake more
frequently and experience fragmented sleep, which leads to less deep
sleep.

It has been estimated that insomnia affects nearly half
of all those over the age of 65 years. Some medical conditions, such as
arthritis, dementia, Parkinson's, congestive heart disease, chronic
obstructive lung disease, depression, sleep apnea, restless legs
syndrome, nocturia related to benign prostatic hypertrophy in men, and
bladder instability with decreased urethral resistance in women, are
common causative factors. Many drugs and ingested substances, such as
caffeine and alcohol have been shown to contribute to insomnia too.

To improve sleeping quality, other than treating the underlying

medical conditions, here are my suggestions. Lower room temperature to
65°F; turn off the electronic devices and darken the room; practice
mindful meditation; eat a small meal and finish dinner 2 hours before
bed; exercise regularly; sun exposure 45 min. a day; try acupuncture,
herbs, and aromatherapy.
