How to Use iPhone 6s as a Scale to Weigh Items. The 3D Touch display on iPhone 6s and iPhone 6s Plus is able to detect pressure applied to the screen in order to serve the 3D Touch pop and peek functions, but with the help of a little third party web app you can transform the iPhone and 3D Touch display into a fairly precise scale.
The feeling of slight dizziness or lightheadedness is a common side effect of donating blood. A healthy donor is capable of donating about 1 pint of blood by volume without any serious side effects following blood donation. This amount of blood loss can be replenished within a dayâs time. The side effects of donating blood are mostly temporary in nature, which subside on their own within a day or two.
Donating blood is a safe process. Each donorâs blood is collected through a new, sterile needle that is used once and then discarded. Although most people feel fine after donating blood, a small number of people may feel lightheaded or dizzy, have an upset stomach or experience a bruise or pain where the needle was inserted.
