Can Wearing a Tie Reduce Blood Flow to Your Brain?

💡 The Answer

• A 2018 study found that wearing a necktie reduces blood flow to the brain by up to 7.5 per cent.
• This reduction can cause dizziness, nausea and headaches in those wearing tight neckties.
• Ties worn too tightly can also increase pressure in the eyes and act as carriers of germs.
• The study used MRI scans to measure cerebral blood flow with and without a necktie.
