Does a warm and sunny climate affect our energy,comparing to a cool and cloudy climate?

Answer 1

The human body operates best within a fairly narrow temperature range and abnormal heat or cold can impose severe stress.There is marked relationship between human mortality and thermal stress.Comparison of daily mortality rates with maximum temperatures suggests deaths occur only in the hottest summers.More people die due to heat waves than due to extreme cold conditions every year.
As per some unconfirmed reports,police record shows that more violent crimes are commited during very hot or stormy weather.
So very hot weather affects our body(and hence our energy) more than a cold weather.

Answer 2

The body has several reactions to hot or cold weather. This reaction is called thermoregulation. When a person is in hot weather, the body reacts by dilating blood vessels close to the skin and begins sweating to allow evaporative cooling to let you get back to your normal temperature. The body does not use much energy to try to cool down, since doing so would actually increase your temperature.

In cold weather, the blood vessels in arms and legs constrict, allowing less heat to escape. Shivering will start, which can increase your metabolism by five times! Also, thyroid hormones in the body are higher in the winter causing your base metabolic rate to increase. This all means that cold weather causes your body to use more energy to thermoregulate; you could feel like you don't have as much energy to go out and do things you enjoy because a lot of energy is being used to keep you going.

In addition, there is a condition known as seasonal affective disorder (S.A.D) in which a person feels depressed in the winter due to a lack of sunlight. This condition can cause the person to become depressed or just feel like they lack enough energy to carry out normal activities.
