There is no way to understand this particular information better without getting to know the several age brackets and the required amount of sleep. Having knowledge of the required number of hours certain age brackets should sleep would give a self determined answer to the question. Below is a breakdown of the several ages and the number of hours people in the age brackets should sleep;

1. 0-3 months - 14-17 hours sleep total

2. 4-12 months - 12 -16 hours sleep total

3. 1-2 years ago - 11-14 hours total number of sleep hours.

4. 3-5 years old - 10-13 number of hours

5. 9-12 years old - 9-12 hours sleep total

6. 13-18 years old - 8-10 hours of sleep time

7. 18-60 years old - atleast 7 hours of sleep daily.

8. 61-64 years old - 7-9 hours of sleep

9. 65 years and above should sleep at least 7-8 hours per night.

Having known the above very important information, the best time to go to sleep at night and also to wake up has to reflect and perfectly match the recommended sleep recommendations for the age group. You can figure out the best time to wake up in the morning based on the time you slept and the recommended number of hours fixated for your age group. There is no one size fits all.

1 Brazil

For anyone travelling to Brazil, be wary of muggers! Street crime is rampant in parts of Rio de Janeiro and Sao Paolo, and whilst many victims are left unharmed, the experience can still scar you.Incidences of “quicknappings” has also risen in major cities. This involves being abducted and taken to an ATM to pay your ransom. If you can’t pay, your family is only a call away.

 

Along with street crime, organized criminal groups have waged wars against police and public institutions that were unable to be bribed. If you survive all that don't forget the drugs and narco-terrorism.

 

2. Russia

The Russian mafia runs wild, there are more gangsters than police, and a Russian is assassinated every 18 minutes, averaging 84 murders per day in a nation of 143 million.

 

Foreigners are kidnapped more frequently due to the higher ransom allocated. Crimes include but are not limited to pickpocketing wallets, cell phones, cameras, cash, and physical assaults.

 

3 South Africa

Any nation described as the ‘rape capital of the world’ should be one to take extra special care in. But rape is not the only vice to be worried about.

 

Another damning statistic for South Africa is its appalling high murder rate. Most crime is confined to poor areas but it hasn’t stopped gated communities springing up all over South Africa and armed guards protecting wealthy tourist groups.

 

Farming in South Africa has become one of the most dangerous professions in the world. And like anywhere, sex can be very dangerous in South Africa, where more than 10 million people are infected with HIV.

4 Burundi

Mass murder and mayhem compete with environmental problems as the biggest headaches for the people of Burundi. The list of assassinated leaders is extensive, and control of the nation has changed hands numerous times in the last 60 years. Th biggest risks for visitors are crimes committed by roaming gangs and armed children. Muggings, carjackings and kidnappings await, so you are advised not to stop the car 

 

5 Afghanistan

Hundreds of people are killed, shredded, and maimed each year due to these insidious devices. Following the Soviets came the Taliban, whose control meant women were banned from jobs and universities.

 

In 2001, the United States overthrew the Taliban, but banditry, tribal rivalries and drug-relatedi violence have left the nation unstable. Suicide bombings are a constant threat, and nobody in Afghanistan is safe.
