Ageism term by Robert Butler in 1969
After age of 65, most people experience this. They get judged by virtue of their age.
According to a study released on Monday, North Americans aren’t getting enough
sleep as they need. The growing habit of using computers, laptops, tvs, and other
electronic devices in the hour before bedtime is not helping
The US-based National Sleep Foundation did this annual poll of Americans. They
asked people when it comes to late night use of computers, tvs, etc, they wanted to
know what their pattern of usage of this technology was. They learnt that artificial
light exposure b/w dusk and the time we go to bed at night suppresses the release of
melatonin. Melatonin is important for sleep, so if you suppress it then you don’t have
enough of it when you go to sleep. As a result, you are more alert and have
difficulties falling asleep.
Another problem they ascertain is that many people go to sleep with their cell phone
on their bedside table. So they are awakened if they get a message or call.

Dr. Robert Butler did study on problems with sleep. Need 7-8 hours of sleep. If you
don’t get enough sleep, it can lead to depression, obesity, diabetes, etc.

condition as to why. For example, people suffering from hypothyroidism would be
tired. Another example is multiple sclerosis; one of the symptoms is fatigue.

tired of all respondents. They were sleepier than even baby boomers. They were
napping b/c they were tired. Lack of sleep causing problems for them. Effecting
mood, family life, social life, and ability to do any work/school work.
Approximately 1/10 people from this survey said they were being awakened from
their sleep from calls, e-mails, texts at night.
