Why do people feel uncomfortable when the weather is hot?

■ Summer depression is related to long days, high temperature and high humidity.

Why do some people feel more depressed in summer? You may have heard of seasonal affective disorder, which affects about 4% to 6% people. Seasonal affective disorder usually causes people to become depressed when the days get shorter and colder in winter. About 10% of patients with seasonal affective disorder are just the opposite, and their depressive symptoms appear because of the arrival of summer. Experts pointed out that research shows that in some countries close to the equator, such as India, emotional disorders are more common in summer than in winter. Why do seasonal changes lead to depression? Experts are not sure, but longer days and increased heat and humidity may play a role. Special symptoms of summer depression usually include loss of appetite, sleep disorder, weight loss and anxiety.

But I hope you have a good attitude. Every day is a beautiful day.
