Starting work before 10 am makes us feel exhausted.
The researchers at Oxford University stated that forcing employees to start work before 10 am is making them ill, exhausted, and stressed. Until the age of 55, our daily rhythms are totally unsynchronized with the “9-to-5” working day, causing a genuine threat to employees’ productivity and their physical, mental, and emotional health.
Waking up early leads to anxiety and frustration.
As Dr. Kelley shared, a lack of sleep may result in changes like mood swings, anxiety, anger, frustration, weight gain, etc. Also, when you wake up unnaturally with the help of an alarm (and a frequently pressed “snooze” button), it makes you feel half asleep when you finally wake up which is known as sleep inertia.
In this way, your work performance can be affected for periods of up to 3-4 hours which is usually linked to major accidents, shared researcher, Stuart McFarlane. This is extra important in regards to jobs that require employees to be part of dangerous situations shortly after waking up, like firefighters, ambulance staff, and pilots.
