It's mid-December and the cold weather continues, but what kind of "warm goods" are you using? We've done a thorough investigation of the warm goods that are actually selling well. We'll also introduce some quick ways to stay warm in winter. ■When should you replace your warm innerwear? How to check the manufacturing year, as told by a Uniqlo representativeYasumi YoshiharaCaster: Let's introduce some warm goods. First, there's Uniqlo's "Heattech." It converts the water vapor from the body into heat and keeps you warm by sticking to your skin. When it no longer sticks to your skin, its function gradually decreases, so it's a good indicator of when to replace it. According to a Uniqlo representative, the guideline for replacing it is three seasons from the time you start wearing it. If you started wearing it last winter, this year will be the second season and next year will be the third season, so you can consider replacing it next year or later. You may have several of these innerwear and not remember when you bought them. In fact, the year and month of manufacture are written on Heattech. Sometimes it is printed directly on the product, but pay attention to the numbers in parentheses [ ] on the washing tag. If it says [34-02]... The "3" on the far left is the first digit of the year of manufacture, so we can see that it was manufactured in 2023, 2013, or 2003. The second character from the left represents the season. 1 is spring, 2 is summer, 3 is autumn, and 4 is winter. The Heattech actually worn by a staff member (in his 50s) was manufactured and sold in the winter of 2013 or 2003, as he said, "I didn't buy it at least last year." He said, "I think it was 2013, but I'm not sure." ■Even if it's cold, it's best to take off your socks when you go to bed. Gunze conducted a survey of 457 men and women to find out whether they wear socks when they go to bed, with 54% of them wearing socks and 46% not wearing socks, which is about half and half. According to Masumi Kawasaki, a head instructor at the Japan Onkatsu Association, "If you feel your feet are cold, it's best to keep your feet warm by wearing socks until just before you go to bed, and then take them off when you go to sleep." When the body temperature at the center of the body drops, people feel sleepy. When this happens, high heat is released from the feet and hands, but if you wear socks, the heat cannot be released properly, making it harder to feel sleepy and worsening the quality of your sleep, so it's better not to wear socks when you're sleeping. For people who can't sleep when their feet are cold, there is a product called Gunze's "Good Night Socks (880 yen)." These socks have a removable toe cover that turns them into leg warmers. They can be worn as socks, and when you go to sleep, you can remove the toe cover and use them as leg warmers, so they are a "two birds with one stone" item. ■ Where to stick a "one warmer"? When you have a cold lower abdomen, the last thing you want to rely on to warm your whole body is a warmer. If you only have one in an emergency, where should you stick it to warm your whole body? According to Kawasaki, if you want to warm your whole body, it's best to apply it to the lower abdomen. It warms the center of the body, raising body temperature, and warms the internal organs, increasing blood flow. There are large blood vessels between the shoulder blades, so they also warm up the area. ▼TBS NEWS DIG Official Website https://newsdig.tbs.co.jp/ ▼Please subscribe to our channel! / @tbsnewsdig ▼Information provided by "TBS Insiders" https://www.tbs.co.jp/news_sp/tbs-ins... ▼Video provided by "TBS Scoop Post" https://www.tbs.co.jp/news_sp/toukou.... #News #news #TBS #newsdig
