DOES SELTZER CAUSE CAVITIES?
Though it’s as hydrating as regular water, soda is an acidic beverage which can break down the enamel of your teeth and leave them vulnerable to decay. But like lemon water, seltzer isn’t acidic enough to cause erosion, explains Matthew Messina, DDS, Columbus, Ohio-based spokesperson for the American Dental Association. You can hydrate with seltzer without needing to brush your teeth afterwards, though if you’re drinking one that’s artificially colored, you may want to brush after to avoid staining.

YOU’LL HONE YOUR CHRONOTYPE.
“Circadian rhythms are going to get tailored even more specifically to an individual’s inherent physiological wiring, and their subtle shifts depending on season, body need, hormonal/menstrual cycle, and intellectual patterns,” says Deanna Minich, Ph.D., Equinox Health Advisory Board member and author of The Rainbow Diet. For example, a recent study by Russian researchers identified not just the classical “morning lark” and “night owl” chronotypes, but six distinct circadian rhythms. “This will enable people to determine a health regimen to help them optimize their hypothalamic signals (the hypothalamus is the powerhouse from where the other metabolic signals are sent) which could potentially help with sleep, appetite, temperature control, and even stress response.”

SET TWO ALARMS.
“Even the most motivated of us need a little nudge in the right direction,” says Toby Massenburg, group fitness manager at Hollywood in California. If one of your 2021 goals is to become a morning exerciser, set two alarms, he suggests. “It’s a great way to hold yourself accountable. You might ignore the first alarm or get distracted with other things. The second one creates a sense of urgency."
