How New Hampshire's climate shapes wellness

Much of New Hampshire has a humid continental climate — four distinct seasons, with warm to hot summers and cold winters that bring snow and short days. Seasonal shifts in light and temperature affect sleep, mood, activity and vitamin D, so a winter plan matters as much as a summer one.

FAQ

New Hampshire wellness FAQs

Do I need to visit a clinic in New Hampshire for a wellness genetic test?

No clinic visit is needed. At-home wellness genetic tests ship to New Hampshire: you collect a sample at home, mail it back and review results online — ideally with a clinician in New Hampshire who can put them in context. See our genetic testing guide.

How do you stay active through New Hampshire's winters?

Plan indoor options before it gets cold — a gym, pool or home strength routine — and keep daily walks going by dressing in layers. Morning light and a steady sleep schedule help counter the energy dip many people feel on short winter days.

Can you get enough vitamin D from the sun in New Hampshire?

New Hampshire sits at about 43.7°N. At this latitude, winter sunlight is too weak for meaningful vitamin D production for roughly four months. That's roughly November through February. Skin tone, sunscreen, age and time outdoors also matter, so a blood test is the only way to know your level — ask your clinician before supplementing.
