Feeling hot and sweaty during plasma donation is a common reaction. It's mainly due to the body's response to the blood components being returned during the plasma collection process. Plasma donation involves removing blood, separating the plasma, and then returning the remaining components back to your body. This can cause a slight decline in blood calcium levels, leading to a sensation of warmth or heat. Staying hydrated and having a small, calcium-rich snack before donating can help mitigate these sensations.
