Imagine being in a sauna for a few hours. Then imagine getting out of it and walking straight into a giant freezer for another few hours. Do this several times a day and continue the routine for a couple of months. Some people say that’s what spending summer in Japan is like.
Japan’s summer months are notoriously hot and muggy, which can lead to a range of health problems. Natsubate (summer fatigue) leaves people feeling tired, lethargic and/or sleep-deprived. Many people lose their appetite and become irritated, while others suffer digestive problems such as diarrhea, constipation and/or giddiness.
