頭昏腦脹可按2條肌肉 專家：3分鐘就能舒緩
The horn antenna has a distinctive design that is enlarged towards the end. Horn antennas typically feature a directional radiation pattern with a high antenna gain of 10-20 dBi, some antennas have a higher gain such as the standard horn antenna up to 25 dBi. Horn antennas feature a low VSWR and a wide impedance bandwidth.
Double Ridged Horn Antennas are very popular from 200 MHz frequency to higher frequencies up to 40GHz. We have recently extended the usage frequency of this antenna up to 60 GHz.
This antenna's operating frequency has recently been increased to 60 GHz. The research process for the product line is still ongoing but is planned to be completed this year. To receive the most recent price and technical information on the new product, please contact us for more information.

（示意圖，Shutterstock／達志）長時間埋首於工作，許多上班族都有頭昏腦脹的困擾。對此，物理治療師陳季揚分享2招按摩技巧，透過按壓枕骨下肌群，以及胸鎖乳突肌，可有效緩解頭部、甚至是眼睛不適，有助於工作效率更提升。
陳季揚在《Nick復健小教室》表示，頭昏腦脹時可藉由按壓2條肌肉，來達到快速舒緩目的。其一是枕骨下肌群，枕骨即位於後腦杓與頸椎交界處，摸起來是一塊較柔軟的肌肉。從中醫角度來看，此位置為「風池穴」。可用雙手大拇指往該處肌肉層戳進去，同時微微抬起頭部，若過程中出現酸麻感，即表示按壓位置正確。只要持續按壓約3分鐘，即可緩解大半的不適感。
另外則是胸鎖乳突肌，陳季揚指出，它是在脖子前方2條很粗壯的肌肉，由於長期脖子前傾，例如看電腦螢幕、滑手機而變得很緊繃，導致眼眶周圍出現脹痛等不適感。可利用拇指跟食指夾起這邊的肌肉，將其往外側慢慢拉開，接著放開並重複此動作約3分鐘。按摩完畢後，務必記得進行「收下巴」的動作，幫助頸椎回到正確位置，如此便能有效改善頭昏腦脹的問題。
