Why do we go to the bathroom more often when the weather is cold than when the weather is hot?

Why is it cold in winter and hot in summer? Some people may think that we are far away from the sun in winter and the opposite in summer. In fact, this idea is completely wrong. The earth revolves around the sun in an ellipse that is close to a perfect circle. The closest date to the earth to the sun is in early January, and the farthest distance is in early July. , that is to say, it is the coldest season in the Northern Hemisphere when we are closest to the earth. This also shows that when the earth orbits the sun, the distance of the earth from the sun is not the factor that determines the coldness and warmth. The correct explanation is this:

The four seasons are mainly due to the oblique intersection of the equator and the ecliptic (the path of the sun as seen on the earth). As the Earth rotates, its axis of rotation remains oriented in space. In winter, the sun's rays slant on the ground, and each unit area on the ground receives less heat. In addition, the day is short, and the time of sunlight is short every day, that is, the time of heating is short. Furthermore, the outer atmosphere of the earth absorbs part of the light and heat. When light is irradiated, it passes through the thicker atmosphere and absorbs more, thus causing cold winter. In summer, on the contrary, the sun shines directly on the ground, the days are long, and the light passes through the atmosphere thinly, so the climate is hot. The spring and autumn rainy seasons are between winter and summer, so the climate is mild. This is because in winter, the altitude angle of the sun is smaller, the sun's light shines on the earth obliquely, the energy density of solar energy reaching the earth is smaller, and the earth obtains less energy from the sun, so the winter is cold; while in summer, the sun The altitude angle is large, the sunlight is almost directly hitting the earth, and the energy density of the solar energy reaching the earth is very high. The earth obtains more energy from the sun, so it is hot in summer. Because the earth revolves around the sun in an ellipse, in winter, our earth is closer to the sun; in summer, our earth is farther away from the sun.
