Taking a mental health day is just as valid as taking one for a cold or migraine — but saying so out loud can feel uncomfortable, especially if you’re not sure what to say, how much to share, or how your employer might respond.

Whether you’re texting your manager, calling your supervisor, or emailing HR, this guide offers supportive, honest wording for different levels of openness — with examples you can copy, adapt, and use.

🧠 Why Mental Health Days Matter

Your brain is part of your body — and when it needs rest, care, or space, that’s not weakness. It’s health. Burnout, anxiety, depression, and emotional overload are legitimate reasons to take time off.

📞 What to Say When Calling In Sick for Mental Health

Here are 4 tone options, depending on your situation and comfort level.

1. ✅ Simple & Professional (No Details Needed)

“Hi [Name], I’m not feeling well today and won’t be able to work. I’m taking a sick day and will keep you posted on tomorrow. Thanks for understanding.”

This works well if:

• You don’t want to disclose it’s mental health
• Your workplace culture is formal or private

2. 💬 Open But Brief

“Hi [Name], I’m feeling mentally unwell and need to take a day to focus on my mental health. I’m taking a sick day and appreciate your support.”

Use this if:

• You want to normalize the conversation
• Your company encourages wellness and openness

3. ❤️ More Personal or Conversational

“Hey [Name], I’ve been feeling really overwhelmed and mentally drained. I need to take a mental health day today to reset. Thanks for your support.”

Helpful when:

• You’re close with your manager
• You want to humanize the situation

4. 📝 For Email or HR Notification

Subject: Sick Day — [Your Name]

Hi [Manager/HR],

I’m reaching out to let you know I need to take a sick day today due to mental health reasons. I’ll be offline and resting, and I’ll check in tomorrow to update on my availability.

Thanks for your understanding,

[Your Name]

⚠️ A Note About Company Policy

Some workplaces allow mental health days under general sick leave — others may require more formal documentation. If you’re unsure, check your employee handbook or ask HR in a separate conversation.

🧘 Final Thought

Taking a mental health day is a form of self-respect — and setting that boundary shows strength, not weakness. Whether you say it plainly or keep it short and professional, what matters is honoring what you need.
