Summer is coming soon. When is the best time for swimming in the day in summer?
If you would like to swim indoors, a good time in the day is the early hours-the body has the most energy to use because the body has woken up and will be ready for all kinds of different activities of the day. The body is going to work with enough energy and therefore a person will feel more comfortable if he swims during the early hours of the day.
Swimming early in the day can also be good for anyone who plans to swim outdoors. The conditions outside will be excellent: the water will not be too cold or too hot, and the air will be just clean and fine. Everything is suitable.
Usually, it is not a good idea to swim later in the day because one’s body is tired after work for a whole day and also the weather conditions can be the worst in the later parts of the day.
However, there are still some exceptions. Different people feel different and one’s body acts differently at different time of the day. When a person is feeling active and is not tired at all after work, it may be a better time to swim for him than for others. If he is alert(警觉的) that time, he is safe in the water.
In a word, the best time can change for every person. The person’s body condition decides when the best time for swimming is.
