Postal Bulletin

The May 26 Postal Bulletin cover.

The Postal Bulletin’s latest issue features summertime tips for avoiding heat stress.

High temperatures, humidity and direct sun exposure can increase the risk of heat stress. Symptoms can include headache, nausea, muscle cramps, fatigue and dizziness.

The 52-page issue also highlights two new stamps: the Views of Our Planets and Pluto — Explored!
