Mississauga residents will be able to enjoy an extra hour of sleep on Saturday night, and their health and brain power are set to benefit from the extra hour.

Daylight Saving Time ends at 2am on Sunday morning, meaning that the clocks are put back, so instead of it being 2.01am on Sunday, the clocks change to 1.01am.

Extra sleep is linked to protection against illnesses such as diabetes, cancer, heart disease, inflammation and stress. Local hospitals should see decrease in heart attacks after the clocks move an hour back this autumn.

Changing the clocks cannot create extra daylight, but it can adjust the sun to rise and set at different times on your clock. When we spring forward an hour in spring, we add one hour of natural daylight to our afternoon schedule.

Daylight Saving Time has been used for more than 100 years. But is it worth it?

Many Canadians do not understand the benefits of daylight saving time. So why do more than 70 countries in the world still use daylight savings time?

An argument can be made that longer evenings motivate people to get out of the house. The extra hour of daylight can be used for outdoor recreation and sports.

Local Mississauga businesses benefit from brighter evenings. Longer nights give people more time to go shopping, to restaurants, or other events, boosting the local economy.

When daylight savings time was introduced, more daylight was a good thing because it meant less use of artificial light, helping to save energy.

One of the goals is to make sure that people’s active hours coincide with daylight hours so that less artificial light is needed. This makes little sense close to the equator where the amount of daylight does not vary much in a year, or near the poles where the difference between winter and summer daylight hours is very large.

Changing the time, even if it is only by one hour, disrupts our body clocks or circadian rhythm. For most people, the resulting tiredness is simply an inconvenience. For some, however, the time change can have more serious consequences.

Studies link the lack of sleep at the start of daylight savings time to car accidents, workplace injuries, suicide, and more. Early evening darkness after the end of the daylight savings period is linked to depression.

The risk of suffering a heart attack is also increased when daylight savings begins. However, the extra hour of sleep when the clocks move forward has in turn been linked to fewer heart attacks.
